1. There were 2 Important Reasons for undertaking this Series of Posts …
(a) The General Public, and particularly Client Organizations, should be facilitated in directly accessing the core content of the 2005 NIST WTC Recommendations. Up to now, many people have found this to be a daunting task. More importantly, I also wanted to clearly show that implementation of the Recommendations is still proceeding far too slowly … and that today, many significant aspects of these Recommendations remain unimplemented. Furthermore, in the case of some recent key national standards, e.g. British Standard BS 9999, which was published in 2008 … the NIST Recommendations were entirely ignored.
As a golden rule … National Building Codes/Regulations and National Standards … cannot, should not, and must not … be applied without informed thought and many questions, on the part of a building designer !
(b) With the benefit of hindsight, and our practical experience in FireOx International … I also wanted to add a necessary 2011 Technical Commentary to the NIST Recommendations … highlighting some of the radical implications, and some of the limitations, of these Recommendations … in the hope of initiating a much-needed and long overdue international discussion on the subject.

” Architecture is the language of a culture.”
” A living building is the information space where life can be found. Life exists within the space. The information of space is then the information of life. Space is the body of the building. The building is therefore the space, the information, and the life.”
C.Y. Lee & Partners Architects/Planners, Taiwan
[ This is a local dialect of familiar Architectural Language. However, the new multi-aspect language of Sustainable Design is fast evolving. In order to perform as an effective and creative member of a Trans-Disciplinary Design & Construction Team ... can Fire Engineers quickly learn to communicate on these wavelengths ?? Evidence to date suggests not ! ]
.
2. ‘Climate Change’ & ‘Energy Stability’ – Relentless Driving Forces for Sustainable Design !
Not only is Sustainable Fire Engineering inevitable … it must be ! And not at some distant point in the future … but now … yesterday !! There is such a build-up of pressure on Spatial Planners and Building Designers to respond quickly, creatively, intuitively and appropriately to the relentless driving forces of Climate Change (including climate change mitigation, adaptation, and severe weather resilience) and Energy Stability (including energy efficiency and conservation) … that there is no other option for the International Fire Science and Engineering Community but to adapt. Adapt and evolve … or become irrelevant !!
And one more interesting thought to digest … ‘Green’ is not the answer. ’Green’ looks at only one aspect of Sustainable Human & Social Development … the Environment. This is a blinkered, short-sighted, simplistic and ill-conceived approach to realizing the complex goal of a Safe and Sustainable Built Environment. ‘Green’ is ‘Sustainability’ for innocent children !!

(a) Organization for Economic Co-Operation & Development (OECD) – 2012′s Environmental Outlook to 2050
Extract from Pre-Release Climate Change Chapter, November 2011 …
‘ Climate change presents a global systemic risk to society. It threatens the basic elements of life for all people: access to water, food production, health, use of land, and physical and natural capital. Inadequate attention to climate change could have significant social consequences for human wellbeing, hamper economic growth and heighten the risk of abrupt and large-scale changes to our climatic and ecological systems. The significant economic damage could equate to a permanent loss in average per capita world consumption of more than 14% (Stern, 2006). Some poor countries would be likely to suffer particularly severely. This chapter demonstrates how avoiding these economic, social and environmental costs will require effective policies to shift economies onto low-carbon and climate-resilient growth paths.’
(b) U.N. World Meteorological Organization (WMO) Greenhouse Gas Bulletin No.7, November 2011
Executive Summary …
The latest analysis of observations from the WMO Global Atmosphere Watch (GAW) Programme shows that the globally averaged mixing ratios of Carbon Dioxide (CO2), Methane (CH4) and Nitrous Oxide (N2O) reached new highs in 2010, with CO2 at 389.0 parts per million (ppm), CH4 at 1808 parts per billion (ppb) and N2O at 323.2 ppb. These values are greater than those in pre-industrial times (before 1750) by 39%, 158% and 20%, respectively. Atmospheric increases of CO2 and N2O from 2009 to 2010 are consistent with recent years, but they are higher than both those observed from 2008 to 2009 and those averaged over the past 10 years. Atmospheric CH4 continues to increase, consistent with the past three years. The U.S. National Oceanic & Atmospheric Administration (NOAA) Annual Greenhouse Gas Index shows that from 1990 to 2010 radiative forcing by long-lived Greenhouse Gases (GHG’s) increased by 29%, with CO2 accounting for nearly 80% of this increase. Radiative forcing of N2O exceeded that of CFC-12, making N2O the third most important long-lived Greenhouse Gas.
(c) International Energy Agency (IEA) – World Energy Outlook, November 2011
Extract from Executive Summary …
‘ There are few signs that the urgently needed change in direction in global energy trends is underway. Although the recovery in the world economy since 2009 has been uneven, and future economic prospects remain uncertain, global primary energy demand rebounded by a remarkable 5% in 2010, pushing CO2 emissions to a new high. Subsidies that encourage wasteful consumption of fossil fuels jumped to over $400 billion. The number of people without access to electricity remained unacceptably high at 1.3 Billion, around 20% of the world’s population. Despite the priority in many countries to increase energy efficiency, global energy intensity worsened for the second straight year. Against this unpromising background, events such as those at the Fukushima Daiichi Nuclear Power Plant and the turmoil in parts of the Middle East and North Africa (MENA) have cast doubts on the reliability of energy supply, while concerns about sovereign financial integrity have shifted the focus of government attention away from energy policy and limited their means of policy intervention, boding ill for agreed global climate change objectives.’

[ Not just in the case of Tall, Super-Tall and Mega-Tall Buildings ... but the many, many Other Building Types in the Built Environment ... are Building Designers implementing the 2005 & 2008 NIST WTC Recommendations ... without waiting for Building and Fire Codes/Regulations and Standards to be properly revised and updated ?? Evidence to date suggests not ! ]
.
3. Separate Dilemmas for Client Organizations and Building Designers …
As discussed earlier in this Series … the Fire Safety Objectives of Building and Fire Codes/Regulations are limited to:
- The protection of building users/occupants ; and
- The protection of property … BUT only insofar as that is relevant to the protection of the users/occupants ;
… because the function of Building and Fire Codes is to protect Society. Well, that is supposed to be true ! Unfortunately, not all Codes/Regulations are adequate or up-to-date … as we have been observing here in these posts.
.
Just taking the Taipei 101 Tower as an example, I have very recently sent out three genuine, bona fide e-mail messages from our practice …

Toshiba Elevator & Building Systems Corporation (TELC), Japan.
To Whom It May Concern …
Knowing that your organization was involved in the Taipei 101 Project … we have been examining your WebSite very carefully. However, some important information was missing from there.
For our International Work … we would like to receive technical information on the Use of Elevators for Fire Evacuation in Buildings … which we understand is actually happening in the Taipei Tower, since it was completed in 2004.
The Universal Design approach must also be integrated into any New Elevators.
Can you help us ?

Mr. Thomas Z. Scarangello P.E. – Chairman & CEO, Thornton Tomasetti Structural Engineers, New York.
Dear Thomas,
Knowing that your organization was involved in the structural design of the Taipei 101 Tower, which was completed in 2004 … and in the on-going design of many other iconic tall, super-tall and mega-tall buildings around the world … we have been examining your Company Brochures and WebSite very carefully. However, some essential information is missing.
As you are certainly aware … implementation of the 2005 & 2008 National Institute of Standards & Technology (NIST) Recommendations on the Collapse of WTC Buildings 1, 2 & 7, in New York, on 11 September 2001 … is still proceeding at a snail’s pace, i.e. very slowly. Today, many significant aspects of NIST’s Recommendations remain unimplemented.
For our International Work … we would like to understand how you have responded directly to the NIST Recommendations … and incorporated the necessary additional modifications into your current structural fire engineering designs.
Many thanks for your kind attention. In anticipation of your prompt and detailed response …

Dear Sirs,
Knowing that your architectural practice designed the Taipei 101 Tower, which was completed in 2004 … and, later, was also involved in the design of other tall and super-tall buildings in Taiwan and China … we have been examining your Company WebSite very carefully. However, some essential information is missing.
As you are probably aware … implementation of the 2005 & 2008 U.S. National Institute of Standards & Technology (NIST) Recommendations on the Collapse of WTC Buildings 1, 2 & 7, in New York City, on 11 September 2001 … is still proceeding at a snail’s pace, i.e. very slowly. Today, many significant aspects of NIST’s Recommendations remain unimplemented.
For our International Work … we would like to understand how you have responded directly to the NIST Recommendations … and incorporated the necessary additional modifications into your current architectural designs.
Many thanks for your kind attention. In anticipation of your prompt and detailed response …

So … how many Clients, or Client Organizations, are aware that to properly protect their interests … even, a significant part of their interests … it is vitally necessary that Project-Specific Fire Engineering Design Objectives be developed which will have a much wider scope ? The answer is … not many !
How many Architects, Structural Engineers, and Fire Engineers fully explain this to their Clients or Client Organizations ?
And how many Clients/Client Organizations either know that they should ask, or have the balls to ask … their Architect, Structural Engineer and Fire Engineer for this explanation … and furthermore, in the case of any High-Rise Building, Iconic Building, or Building having an Important Function or an Innovative Design … ask the same individuals for some solid reassurance that they have responded directly to the 2005 & 2008 NIST WTC Recommendations … and incorporated the necessary additional modifications into your current designs … whatever current Building and Fire Codes/Regulations do or do not say ?? A big dilemma !
.
A common and very risky dilemma for Building Designers, however, arises in the situation where the Project Developer, i.e. the Client/Client Organization … is the same as the Construction Organization. The Project Design & Construction Team - as a whole - now has very little power or authority if a conflict arises over technical aspects of the design … or over construction costs. An even bigger dilemma !!

5. Please … Your Comments, Views & Opinions ?!?
The future of Conventional Fire Engineering ended on the morning of Tuesday, 11 September 2001, in New York City … an engineering discipline constrained by a long heritage deeply embedded in, and manacled to, an outdated and inflexible prescriptive approach to Codes/Regulations and Standards … an approach which is irrational, ignores the ‘real’ needs of the ‘real’ people who use and/or occupy ‘real’ buildings … and, quite frankly, no longer makes any scientific sense !!
On the other hand … having confronted the harsh realities of 9/11 and the Mumbai ‘Hive’ Attacks, and digested the 2005 & 2008 NIST WTC Recommendations … Sustainable Fire Engineering … having a robust empirical basis, being ‘person-centred’, and positively promoting creativity … offers the International Fire Science and Engineering Community a confident journey forward into the future … on many diverse routes !
This IS the only appropriate response to the exciting architectural innovations and fire safety challenges of today’s Built Environment.
BUT … what do you think ?

NIST Recommendations 16-20 > Improved People Evacuation

.
2011-11-30: SOME PRELIMINARY COMMENTS …
1. In the First Post of this Series, I wrote …
” As such a high level of performance is expected … indeed demanded … of a Sustainable Building … Sustainable Fire Engineering must be ‘reliability-based’ … in other words, it must have a rational, empirical and scientifically robust basis … “
Sustainable Fire Engineering must also be ‘person-centred’ … i.e. a design process (in whatever architectural or engineering discipline) which places ‘real’ people at the centre of creative endeavours and gives due consideration to their responsible needs, and their health, safety, welfare and security in the Human Environment.
In order to prolong, and if at all possible, significantly extend the Life Cycle of a Sustainable Building beyond 100 years … Fire Engineers must begin to feel at ease … and be comfortable … with the following mainstream Sustainable Design Concepts …
Flexibility: The extent to which a building interior is designed, when new, to be capable of being easily modified at any later stage during the life cycle of that building – with minimal cost and user inconvenience – because of a person’s changing living or working needs.
Adaptability: The extent to which a building, or a building component, is designed when new, or capable of being easily modified at any later stage, to meet the changing life and living needs of the broad range of potential users, who may or may not have activity limitations, or may develop a health condition during the life cycle of that building or component.
Accessibility of a Building: Ease of independent approach, entry, egress (during normal ambient conditions), evacuation (in the event of an emergency) and/or use of a building and its services and facilities, by all of the building’s potential users - with an assurance of individual health, safety and welfare during the course of those activities.
2. Group 5 of the 2005 NIST WTC Recommendations is, by far, the most important … introducing some innovative concepts of ‘real’ evacuation … with nothing too startling. Contrary to the impression given by NIST … these Recommendations are equally valid for complex building types and, in reality, for all but the most simple of low-rise buildings. It is interesting to note, however, that when discussing fire behaviour or structural performance in fire, for example … the NIST texts are confident and direct. Here, when dealing with ‘people’ issues … not so confident, prone to some rambling … and lacking clarity.
Shortly after the 2005 NIST Report (NCSTAR 1) was published, I stated the following on the SDI Corporate WebSite … at this FireOx International Page … http://www.sustainable-design.ie/fire/structdesfire.htm …
” In its treatment of ‘disability’ and ‘people with activity limitations’, the Report does not go far enough, and is seriously flawed.”
Let me explain why …
As you go scan down through NIST’s Recommendations 16-20, you will encounter 1 reference to ‘mobility impaired occupants’ and 2 references to the impersonal ‘mobility impaired’. IF (and that is still a very big ‘if’, because there is still so much rabid resistance to this topic !) … a New Post-9/11 Evacuation Model, or Construct, Dealing with ‘Disability’ is being developed … all of the major impairment groupings (i.e. visual impairment, hearing impairment, physical function impairment, mental/cognitive impairment, and psychological impairment) must be added to the mix from the beginning. In other words, our proper focus of attention must be ‘people with activity limitations’ … not just people with disabilities, but also frail older people (not all older people !), children under the age of 5 years, women in the later stages of pregnancy, people with a health condition, etc.
And … because of the social stigma still firmly attaching to ‘disability’ … many building occupants/users will not self-identify … not even if their lives depend on it !
Concentrating on one group only, i.e. people with mobility impairments, is simplistic and entirely inadequate … and we will all end up, in a few years time, having to graft on a consideration of the other impairment groups.
This is exactly what has already gone wrong with the development of Accessibility Design Guidance during the last 30 years … where ‘people with visual or hearing impairments’ received merely token attention … and ‘people with cognitive or psychological impairments’ received no attention at all ! And … we are now grappling with the challenge of having to graft on additional texts to try to re-balance International Design Guidance on Accessibility of the Built Environment. Been there – done that – I have all of the t-shirts !!
People with Activity Limitations (English) / Personnes à Performances Réduites (French): Those people, of all ages, who are unable to perform, independently and without aid, basic human activities or tasks – because of a health condition or physical/mental/cognitive/psychological impairment of a permanent or temporary nature.
The above Terms (in English and French) include …
- wheelchair users ;
- people who experience difficulty in walking, with or without a facilitation aid, e.g. stick, crutch, calliper or walking frame ;
- frail, older people ;
- the very young (people under the age of 5 years) ;
- people who suffer from arthritis, asthma, or a heart condition ;
- the visually and/or hearing impaired ;
- people who have a cognitive impairment disorder, including dementia, amnesia, brain injury, or delirium ;
- women in the later stages of pregnancy ;
- people impaired following the use of alcohol, other ‘social’ drugs e.g. cocaine and heroin, and some medicines ;
- people who suffer any partial or complete loss of language related abilities, i.e. aphasia ;
- people impaired following exposure to environmental pollution and/or other irresponsible human activities, e.g. war and terrorism ;
and …
- people who experience a panic attack in a fire situation or other emergency ;
- people, including firefighters, who suffer incapacitation as a result of exposure, during a fire, to poisonous or toxic substances, and/or elevated temperatures.
3. So … what provision should be made for ‘people with activity limitations’ in typical Fire Engineering Design Projects ?
Equivalent to the concept of Maximum Credible Fire Scenario, which has already been discussed in this Series … at FireOx International, some years ago, we developed the concept of …
Maximum Credible User Scenario
Representing building user conditions which are also severe but reasonable to anticipate …
a) 10% of People Using the Building (occupants, visitors and other users) have an Impairment (visual or hearing, physical function, mental or cognitive, psychological, with some impairments not being identifiable) ;
[ This performance indicator appears in ISO FDIS 21542: 'Building Construction - Accessibility & Usability of the Built Environment', which will soon be published.]
b) The Number of People Using a Building increases, on occasions which cannot be specified, to 120% of designed/calculated maximum building capacity.
[ Generally ... the fire safety related texts contained in ISO 21542 are based on the 2005 & 2008 NIST WTC Recommendations.]
4. With regard to Recommendation 17 below, and NIST’s reference to the widths of evacuation staircases and door openings, etc … fire codes and regulations, fire authorities having jurisdiction (AHJ’s), and even the fire services themselves … still have a crazy mixed-up approach to defining the width of these building features … an approach which I am not even going to attempt to repeat ! Forget it !!
Without Exception … all understandings of Evacuation Route Width, Evacuation Staircase Width and Evacuation Door Opening Width … must be harmonized with the following definitions of Unobstructed Width …
Unobstructed Width – General
Free, unobstructed space – clear of all obstacles below a height of 2.1 metres above finished floor level – necessary for passage along a circulation route, or other route component, e.g. a staircase.
[ For example ... the Unobstructed Width of a Staircase is the clear dimension from the edge of one handrail to the edge of the opposite handrail ... and there is always a continuous handrail on each side of an evacuation staircase ! ]
Unobstructed Width – Door Opening
Free, unobstructed space – clear of all obstacles below a height of 2.0 metres above finished floor level – necessary for passage through a door opening, measured when the door leaf is opened to an angle of 90°, or when a sliding or folding door leaf is opened to its fullest extent.
[ For example ... the Unobstructed Width of a Door Opening is the dimension from the edge of the door leaf (when open at an angle of 90°) to the nearest edge of the door frame.]
This FireOx International Page on the SDI Corporate WebSite provides more guidance … http://www.sustainable-design.ie/fire/appendixd.htm
5. With regard to Recommendation 20 below, and NIST’s reference to allowing “all occupants an equal opportunity for evacuation” … this is not just a ‘nice idea’, or an ‘idealistic notion’ … this is now a Human and Social Right which is backed up and supported by International Law ! And … it is no longer acceptable for the Fire Science and Engineering Community to continue its stubborn resistance in the face of this fact !!
For the benefit of my fire engineering colleagues … I will, once again here, reproduce the most relevant extracts from the United Nations Convention on the Rights of Persons with Disabilities …
UN CRPD Preamble Paragraph (g)
Emphasizing the importance of mainstreaming disability issues as an integral part of relevant strategies of sustainable development, …
UN CRPD Article 9 – Accessibility
1. To enable persons with disabilities to live independently and participate fully in all aspects of life, States Parties shall take appropriate measures to ensure to persons with disabilities access, on an equal basis with others, to the physical environment, to transportation, to information and communications, including information and communications technologies and systems, and to other facilities and services open or provided to the public, both in urban and in rural areas. These measures, which shall include the identification and elimination of obstacles and barriers to accessibility, shall apply to, inter alia:
(a) Buildings, roads, transportation and other indoor and outdoor facilities, including schools, housing, medical facilities and workplaces ;
(b) Information, communications and other services, including electronic services and emergency services.
2. States Parties shall also take appropriate measures:
(a) To develop, promulgate and monitor the implementation of minimum standards and guidelines for the accessibility of facilities and services open or provided to the public ;
(b) To ensure that private entities that offer facilities and services which are open or provided to the public take into account all aspects of accessibility for persons with disabilities ;
(c) To provide training for stakeholders on accessibility issues facing persons with disabilities ;
(d) To provide in buildings and other facilities open to the public signage in Braille and in easy to read and understand forms ;
(e) To provide forms of live assistance and intermediaries, including guides, readers and professional sign language interpreters, to facilitate accessibility to buildings and other facilities open to the public ;
(f) To promote other appropriate forms of assistance and support to persons with disabilities to ensure their access to information ;
(g) To promote access for persons with disabilities to new information and communications technologies and systems, including the Internet ;
(h) To promote the design, development, production and distribution of accessible information and communications technologies and systems at an early stage, so that these technologies and systems become accessible at minimum cost.
UN CRPD Article 11 – Situations of Risk & Humanitarian Emergencies
States Parties shall take, in accordance with their obligations under international law, including international humanitarian law and international human rights law, all necessary measures to ensure the protection and safety of persons with disabilities in situations of risk, including situations of armed conflict, humanitarian emergencies and the occurrence of natural disasters.
[ Note: An outbreak of fire in a building is a situation of serious risk for all vulnerable building occupants/users.]
.
At the time of writing, 153 Countries had signed the UN CRPD … while 106 Countries have ratified the Convention and are, therefore, the ‘State Parties’ referred to above.
These are just a few of the State Parties to the UN CRPD …
- Argentina (ratified the UN CRPD, 2008-09-02)
- Australia (ratified the UN CRPD, 2008-07-17)
- Brazil (ratified the UN CRPD, 2008-08-01)
- Canada (ratified the UN CRPD, 2010-03-11)
- China (ratified the UN CRPD, 2008-08-01)
- Cuba (ratified the UN CRPD, 2007-09-06)
- European Union (ratified the UN CRPD, 2010-12-23)
- India (ratified the UN CRPD, 2007-10-01)
- Malaysia (ratified the UN CRPD, 2010-07-19)
- Mexico (ratified the UN CRPD, 2007-12-17)

- Turkey (ratified the UN CRPD, 2009-09-28)
- United Arab Emirates (ratified the UN CRPD, 2010-03-19)
I wonder how implementation is proceeding in these countries !?!

2005 NIST WTC RECOMMENDATIONS
GROUP 5. Improved Building Evacuation
Building evacuation should be improved to include system designs that facilitate safe and rapid egress, methods for ensuring clear and timely emergency communications to occupants, better occupant preparedness regarding their roles and duties for evacuation during emergencies, and incorporation of appropriate egress technologies.*
[ * F-36 This effort should include standards and guidelines for the development and evaluation of emergency evacuation plans, including best practices for both partial and full evacuation, and the development of contingency plans that account for expected conditions that may require adaptation, including the compromise of all or part of an egress path before or during evacuation, or conditions such as widespread power failure, earthquake, or security threat that restrict egress from the building. Evacuation planning should include the process from initial notification of the need to evacuate up to the point when occupants arrive at a place where their safety is ensured. These standards and guidelines should be suitable for assessing the adequacy of evacuation plans submitted for approval, and should require occupant training through the conduct of regular drills.]
NIST WTC Recommendation 16.
NIST recommends that public agencies, non-profit organizations concerned with building and fire safety, and building owners and managers develop and carry out public education and training campaigns, jointly and on a nationwide scale, to improve building occupants’ preparedness for evacuation in case of building emergencies. This effort should include better training and self-preparation of occupants, an effectively implemented system of floor wardens and building safety personnel, and needed improvements to standards. Occupant preparedness should include:
a. Improved training and drills for building occupants to ensure that they know evacuation procedures for a variety of emergency scenarios (e.g. including evacuation and shelter in place), are familiar with the egress route, and are sufficiently aware of what is necessary if evacuation is required with minimal notice (e.g. footwear consistent with the distance to be travelled, a flashlight/glow stick for pathway illumination, and dust masks).
b. Building owners and managers should educate tenants on the life safety systems present in their building(s), provide training materials explaining egress routes and stairwell and elevator information, and develop educational programmes explaining the most appropriate responses in emergency situations. It is further recommended that the owners and managers of office buildings implement the necessary systems for collecting and storing the training history of each building occupant.
c. Improved training and drills that routinely inform building occupants that roof rescue is not (or is) presently feasible as a standard evacuation option, that they should evacuate down the stairs in any full-building evacuation unless explicitly instructed otherwise by on-site incident commanders, and that elevators can be used if they are still in service and haven’t been recalled or stopped.
d. Improved codes, laws, and regulations that do not restrict or impede building occupants during evacuation drills from familiarizing themselves with the detailed layout of alternative egress routes for a full building evacuation.*
[ * F-37 New York City Local Law 5 prohibits requiring occupants to practice stairwell evacuation during drills.]
Affected Standard: ICC/ANSI A117-1. Model Building and Fire Codes: The standard should be adopted in model building and fire codes by mandatory reference to, or incorporation of, the latest edition of the standard. Affected Organizations: NFPA, NIBS, NCSBCS, BOMA, and CTBUH.
NIST WTC Recommendation 17.
NIST recommends that tall buildings be designed to accommodate timely full building evacuation of occupants when required in building-specific or large-scale emergencies such as widespread power outages, major earthquakes, tornadoes, hurricanes without sufficient advance warning, fires, explosions, and terrorist attack. Building size, population, function, and iconic status should be taken into account in designing the egress system. Stairwell capacity and stair discharge door opening width* should be adequate to accommodate contraflow due to emergency access by responders.
[ * F-38 Egress capacity should be based on an all-hazards approach that considers the number and width of stairs (and door openings) as well as the possible use of scissor stairs credited as a single stair.]
a. Improved egress analysis models, design methodology, and supporting data should be developed to achieve a target evacuation performance (e.g. time for full building evacuation*) for the design building population by considering the building and egress system designs, and human factors such as occupant size, mobility status, stairwell tenability conditions, visibility, and congestion.
[ * F-39 Use of egress models is required to estimate the egress capacity for a range of different evacuation strategies, including full building evacuation. NIST found that the average surviving occupant in the WTC towers descended stairwells at about half the slowest speed previously measured for non-emergency evacuations.]
b. To the degree possible, mobility impaired occupants should be provided a means for self-evacuation in the event of a building emergency. Current strategies (and law) generally require the mobility impaired to shelter in place. New procedures, which provide redundancy in the event that the floor warden system or co-worker assistance (i.e. a buddy system) fails, should consider full building evacuation, and may include use of fire-protected and structurally hardened elevators,* motorized evacuation technology (e.g. a battery-operated evacuation chair), and/or dedicated communication technologies for the mobility impaired.
[ * F-40 Elevators should be explicitly designed to provide protection against large, but conventional, building fires. Fire-protected elevators also should be structurally hardened to withstand the range of foreseeable building-specific or large-scale emergencies. While progress has been made in developing the requirements and technologies for fire-protected elevators, similar criteria and designs for structurally hardened elevators remain to be developed.]
c. If protected/hardened elevators are provided for emergency responders but become unusable during an emergency, due to a malfunction or a conventional threat whose magnitude exceeds the magnitude considered in design, sufficient stairwell capacity should be provided to ensure timely emergency responder access to buildings that are undergoing full evacuation. Such capacity could be provided either via dedicated stairways for fire service use or by building sufficient stairway capacity (i.e. number and width of stairways and/or use of scissor stairs credited as a single stair) to accommodate the evacuation of building occupants while allowing access to emergency responders with minimal hindrance from occupant contraflow.
d. The egress allowance in assembly use spaces should be limited in state and local laws and regulations to no more than a doubling of the stairway capacity for the provision of a horizontal exit on a floor, as is the case now in the national model codes.* The use of a horizontal exit creates an area of refuge with a 2 hour fire rated separation, at least one stair on each side, and sufficient space for the expected occupant load.
[ * F-41 The New York City Building Code permits a doubling of allowed stair capacity when one area of refuge is provided on a floor, and a tripling of stair capacity for two or more areas of refuge on a floor. In the world after 11 September 2001, it is difficult to predict: (1) if, and for how long, occupants will be willing to wait in a refuge area before entering an egress stairway; and (2) what the impact would be of such a large group of people moving down the stairs on the orderly evacuation of lower floors.]
Affected Standards: NFPA 101, ASME A 17. Model Building and Fire Codes: The standards should be adopted in model building and fire codes by mandatory reference to, or incorporation of, the latest edition of the standard.
NIST WTC Recommendation 18.
NIST recommends that egress systems be designed: (1) to maximize remoteness of egress components (i.e. stairs, elevators, exits) without negatively impacting on average travel distances; (2) to maintain their functional integrity and survivability under foreseeable building-specific or large-scale emergencies; and (3) with consistent layouts, standard signage, and guidance so that systems become intuitive and obvious to building occupants during evacuations.
a. Within a safety-based design hierarchy that should be developed, highest priority should be assigned to maintain the functional integrity, survivability, and remoteness of egress components and active fire protection systems (sprinklers, standpipes, associated water supply, fire alarms, and smoke management systems). The design hierarchy should consider the many systems (e.g. stairs, elevators, active fire protection, mechanical, electrical, plumbing, and structural) and system components, as well as functional integrity, tenant access, emergency responder access, building configuration, security, and structural design.
b. The design, functional integrity, and survivability of the egress and other life safety systems (e.g. stairwell and elevator shafts, and active fire protection systems) should be enhanced by considering accidental structural loads such as those induced by overpressures (e.g. gas explosions), impacts, or major hurricanes and earthquakes, in addition to fire separation requirements. In selected buildings, structural loads due to other risks such as those due to terrorism may need to be considered. While NIST does not believe that buildings should be designed for aircraft impact, as the last line of defence for life safety, the stairwells and elevator shafts individually, or the core if these egress components are contained within the core, should have adequate structural integrity to withstand accidental structural loads and anticipated risks.
c. Stairwell remoteness requirements should be met by a physical separation of the stairwells that provide a barrier to both fire and accidental structural loads. Maximizing stairwell remoteness, without negatively impacting on average travel distances, would allow a stairwell to maintain its structural integrity independent of any other stairwell that is subject to accidental loads, even if the stairwells are located within the same structural barrier such as the core. The current ‘walking path’ measurement allows stairwells to be physically next to each other, separated only by a fire barrier. Reducing the clustering of stairways that also contain standpipe water systems provides the fire service with increased options for formulating firefighting strategies. This should not preclude the use of scissor stairs* as a means of increasing stair capacity – provided the scissor stair is only credited as a single stair.
[ * F-42 Two separate stairways within the same enclosure and separated by a fire rated partition.]
d. Egress systems should have consistent layouts with standard signage and guidance so that the systems become intuitive and obvious to all building occupants, including visitors, during evacuations. Particular consideration should be given to unexpected deviations in the stairwells (e.g. floors with transfer hallways).
Affected Standard: NFPA 101. Model Building and Fire Codes: The standard should be adopted in model building and fire codes by mandatory reference to, or incorporation of, the latest edition of the standard.
NIST WTC Recommendation 19.
NIST recommends that building owners, managers, and emergency responders develop a joint plan and take steps to ensure that accurate emergency information is communicated in a timely manner to enhance the situational awareness of building occupants and emergency responders affected by an event. This should be accomplished through better co-ordination of information among different emergency responder groups, efficient sharing of that information among building occupants and emergency responders, more robust design of emergency public address systems, improved emergency responder communication systems, and use of the Emergency Broadcast System (now known as the Integrated Public Alert and Warning System) and Community Emergency Alert Networks.
a. Situational awareness of building occupants and emergency responders in the form of information and event knowledge should be improved through better co-ordination of such information among emergency responder groups (9-1-1 dispatch, fire department or police department dispatch, emergency management dispatch, site security, and appropriate federal agencies), efficient sharing and communication of information between building occupants and emergency responders, and improved emergency responder communication systems (i.e. including effective communication within steel and reinforced concrete buildings, capacity commensurate with the scale of operations, and interoperability among different communication systems.
b. The emergency communications systems in buildings should be designed with sufficient robustness and redundancy to continue providing public address announcements or instructions in foreseeable building-specific or large-scale emergencies, including widespread power outage, major earthquakes, tornadoes, hurricanes, fires, and accidental explosions. Consideration should be given to placement of building announcement speakers in stairways in addition to other standard locations.
c. The Integrated Public Alert and Warning System (IPAWS) should be activated and used, especially during large-scale emergencies, as a means to rapidly and widely communicate information to building occupants and emergency responders to enhance their situational awareness and assist with evacuation.
d. Local jurisdictions (cities and counties or boroughs) should seriously consider establishing a Community Emergency Alert Network (CEAN), within the framework of IPAWS, and make it available to the citizens and emergency responders of their jurisdictions to enhance situational awareness in emergencies.* The network should deliver important emergency alerts, information and real time updates to all electronic communication systems or devices registered with the CEAN. These devices may include e-mail accounts, cell/mobile phones, text pagers, satellite phones, and wireless PDA’s.
[ * F-43 Types of emergency communications could include life safety information, severe weather warnings, disaster notifications (including information on terrorist attacks), directions for self-protection, locations of nearest available shelters, precautionary evacuation information, identification of available evacuation routes, and accidents or obstructions associated with roadways and utilities.]
Affected Standard: NFPA 101, and/or a new standard. Model Building and Fire Codes: The standard should be adopted in model building and fire codes by mandatory reference to, or incorporation of, the latest edition of the standard to the extent it is within the scope of building and fire codes.
NIST WTC Recommendation 20.
NIST recommends that the full range of current and next generation evacuation technologies should be evaluated for future use, including protected/hardened elevators, exterior escape devices, and stairwell descent devices, which may allow all occupants an equal opportunity for evacuation and facilitate emergency response access. Affected Standards: NFPA 101, ASME A 17, ASTM E 06, ANSI A117.1. Model Building and Fire Codes: The standards should be adopted in model building and fire codes by mandatory reference to, or incorporation of, the latest edition of the standard.

Corporate Social Responsibility – Updated EU Strategy 2011-14
2011-11-15: The European Commission, in Brussels, recently published a New European Union Policy Document on Corporate Social Responsibility (CSR) … COM(2011) 681 final – Brussels, 2011-10-25.
To access this document … just go down to the EUR-Lex Link on the right hand side of this Page.
The Updated EU CSR Strategy for 2011-2014 signals an important change of direction … more a re-balancing of emphasis … which enterprises, of all sizes, should immediately be aware of … and whether or not these enterprises are located within Europe … or outside, as far away as China, India, Japan, South Africa, the USA or Brazil, etc.
The Updated CSR Strategy also confirms how the merging of the different and interrelated aspects of Sustainable Human & Social Development, i.e. social, economic, environmental, institutional, political and legal … is progressing nicely, and gathering some momentum. We have discussed this issue here many times … and promoted it elsewhere in our work, particularly during the last decade. How time flies !
[ In this last regard, reference should also be made to the United Nations Development Programme (UNDP) 2011 Human Development Report: 'Sustainability and Equity - A Better Future for All', which was launched in Copenhagen on 2 November 2011.]
.
A New Definition for Corporate Social Responsibility (CSR) …
The European Commission puts forward a new definition of CSR as ‘the responsibility of enterprises for their impacts on society’.
Respect for applicable legislation and for collective agreements between social partners are prerequisites for meeting that responsibility. To fully meet their corporate social responsibility, enterprises should have in place a process to integrate social - environmental - ethical - human rights and consumer concerns into their business operations and core strategy in close collaboration with their stakeholders, with the aim of:
- maximising the creation of shared value for their owners/shareholders, and for their other stakeholders and society at large ;
- identifying, preventing and mitigating their possible adverse impacts.
The complexity of that process will depend on factors such as the size of the enterprise and the nature of its operations. For most small and medium-sized enterprises, especially micro-enterprises, the CSR Process is likely to remain informal and intuitive.
To maximise the creation of shared value, enterprises are encouraged to adopt a long-term, strategic approach to CSR, and to explore the opportunities for developing innovative products, services and business models that contribute to Social Wellbeing and lead to higher quality and more productive jobs.
To identify, prevent and mitigate their possible adverse impacts, large enterprises, and enterprises at particular risk of having such impacts, are encouraged to carry out risk-based due diligence, including through their supply chains.
Certain types of enterprise, such as co-operatives, mutuals, and family-owned businesses, have ownership and governance structures that can be especially conducive to responsible business conduct.
.
The Updated EU CSR Strategy elaborates an Action Agenda for 2011-2014 …
1. Improving Company Disclosure of Social and Environmental Information: the new strategy confirms the European Commission’s intention to bring forward a new legislative proposal on this issue.
2. Enhancing Market Reward for CSR: this means leveraging EU Policies in the fields of consumption, investment and public procurement in order to promote market reward for responsible business conduct.
3. Enhancing the Visibility of CSR and Disseminating Good Practices: this includes the creation of a European award, and the establishment of sector-based platforms for enterprises and stakeholders to make commitments and jointly monitor progress.
4. Improving and Tracking Levels of Trust in Business: the European Commission will launch a public debate on the role and potential of enterprises, and organise surveys on citizen trust in business.
5. Better Aligning European and International Approaches to CSR: the European Commission highlights the following …
- OECD Guidelines for Multinational Enterprises ;
- 10 Principles of the UN Global Compact ;
- UN Guiding Principles on Business and Human Rights ;
- ILO Tri-Partite Declaration of Principles on Multinational Enterprises and Social Policy ;
- ISO 26000 Guidance Standard on Social Responsibility.
6. Further Integrating CSR into Education, Training and Research: the European Commission will provide further support for education and training in the field of CSR, and explore opportunities for funding more research.
7. Improving Self- and Co-Regulation Processes: the European Commission proposes to develop a short protocol to guide the development of future self- and co-regulation initiatives.
8. Emphasising the Importance of National and Sub-National CSR Policies: the European Commission invites EU Member States to present or update their own plans for the promotion of CSR by mid 2012.

NIST’s Recommendations on the 9-11 WTC Building Collapses
2011-10-25: Since shortly after my visit to Lower Manhattan in mid-October 2001 … we have maintained an Archive Page on ‘Structural Fire Engineering, World Trade Center Incident (9-11) & Fire Serviceability Limit States‘ … at SDI’s Corporate WebSite. And I have referenced here … many, many times … the Recommendations contained in the 2005 & 2008 Final Reports of the U.S. National Institute of Standards & Technology (NIST) on the 9-11 World Trade Center Building 1, 2 & 7 Collapses.
In this post (and a series of future posts) … I find it most necessary that the 2005 & 2008 NIST Recommendations now be presented for everyone to read. Yes, some of Recommendations apply specifically to Tall and Very Tall Buildings … and Building Designers in India, China, Brazil, Russia & South Africa (BRICS), the Arab Gulf Region, Europe and North America, etc., should be fully aware of their contents.
BUT … I am also strongly convinced … precisely because I am an Architect, a Fire Engineer and a Technical Controller … that most of the NIST Recommendations apply to ALL Buildings … so catastrophic was the failure exposed on that fateful day (11 September 2001) … in all of our common design and construction practices … and our operation, maintenance and emergency response procedures !
.
PRELIMINARY COMMENTS
1. Extract from Paragraph #9.2, Chapter 9, NIST Final Report on the Collapse of the World Trade Center Towers – Report Reference NIST NCSTAR 1 (2005) …
- NIST believes that these Recommendations are both realistic and achievable within a reasonable period of time, and that their implementation would make buildings safer for occupants and emergency responders in future emergencies.
- NIST strongly urges that immediate and serious consideration be given to these Recommendations by the building and fire safety communities – especially designers, owners, developers, codes and standards development organizations, regulators, fire safety professionals, and emergency responders.
- NIST also strongly urges building owners and public officials to: (i) evaluate the safety implications of these Recommendations for their existing inventory of buildings; and (ii) take the steps necessary to mitigate any unwarranted risks without waiting for changes to occur in codes, standards, and practices.
2. At the time of writing … it is important to point out that although they are related Structural Concepts … and there is still, to this day, a lot of confusion about these concepts in the USA … it is important to clearly distinguish between …
Disproportionate Damage
The failure of a building’s structural system (i) remote from the scene of an isolated overloading action; and (ii) to an extent which is not in reasonable proportion to that action.
Fire-Induced Progressive Collapse
The sequential growth and intensification of distortion, displacement and failure of elements of construction in a building – during a fire and the ‘cooling phase’ afterwards – which, if unchecked, will result in disproportionate damage, and may lead to total building collapse.
3. Recommendation 2, below, would certainly need to be understood and implemented within today’s additional design constraints of Sustainable Climate Change Adaptation and Resilience to Severe Weather Events. Therefore … Design Wind Speeds must be increased, accordingly, for ALL Buildings.
4. As such a high level of performance is expected … indeed demanded … of a Sustainable Building … Sustainable Fire Engineering must be ‘reliability-based’. In other words, it must have a rational, empirical and scientifically robust basis … unlike conventional fire engineering, which is yet aimlessly wandering around in pre-historic caves !
5. Finally … there is no use trying to hide the fact that progress on implementing the NIST Recommendations, within the USA, has been lamentably slow. Outside that jurisdiction, the response has ranged from mild interest, to complete apathy, and even to vehement antipathy. The implications arising from implementation are much too hard to digest … for long established fire safety professionals and researchers who are unswervingly committed to the flawed and out-of-date practices and procedures of conventional fire engineering and, especially, for vested interests !
However … is it either in society’s interest, or in the interests of our clients/client organizations … that, to give you a simple example which is relevant close to home, British Standard 9999 (published on 31 October 2008): ‘Code of Practice for Fire Safety in the Design, Management and Use of Buildings’ takes absolutely no account of any of the NIST Recommendations ? As far as the British Standards Institution is concerned … 9-11 never happened … which I think is an inexcusable and unforgivable technical oversight !
For this reason, the General Public in ALL of our societies and Clients/Client Organizations in ALL countries should also be fully aware of the contents of these Recommendations …

2005 NIST WTC RECOMMENDATIONS
GROUP 1. Increased Structural Integrity
The standards for estimating the load effects of potential hazards (e.g. progressive collapse, wind) and the design of structural systems to mitigate the effects of those hazards should be improved to enhance structural integrity.
NIST WTC Recommendation 1.
NIST recommends that: (1) progressive collapse be prevented in buildings through the development and nationwide adoption of consensus standards and code provisions, along with the tools and guidelines needed for their use in practice; and (2) a standard methodology be developed – supported by analytical design tools and practical design guidance – to reliably predict the potential for complex failures in structural systems subjected to multiple hazards.
a. Progressive collapse* should be prevented in buildings.
[ * F-19 Progressive collapse (or disproportionate damage) occurs when an initial local failure spreads from structural element to structural element resulting in the collapse of an entire structure or a disproportionately large part of it.]
The primary structural systems should provide alternate paths for carrying loads in case certain components fail (e.g. transfer girders or columns). This is especially important in buildings where structural components (e.g. columns, girders) support unusually large floor areas.*
[ * F-20 While the WTC towers eventually collapsed, they had the capacity to redistribute loads from impact and fire damaged structural components and sub-systems to undamaged components and sub-systems. However, the core columns in the WTC towers lacked sufficient redundant (alternative) paths for carrying gravity loads.]
Progressive collapse is addressed only in a very limited way in practice and by codes and standards. For example, the initiating event in design to prevent progressive collapse may be removal of one or two columns at the bottom of the structure. Initiating events at multiple locations within the structure, or involving other key components and sub-systems, should be analyzed commensurate with the risks considered in the design. The effectiveness of mitigation approaches involving new system and sub-system design concepts should be evaluated with conventional approaches based on indirect design (continuity, strength and ductility of connections), direct design (local hardening), and redundant (alternate) load paths. The capability to prevent progressive collapse due to abnormal loads should include: (i) comprehensive design rules and practice guides; (ii) evaluation criteria, methodology, and tools for assessing the vulnerability of structures to progressive collapse; (iii) performance-based criteria for abnormal loads and load combinations; (iv) analytical tools to predict potential collapse mechanisms; and (v) computer models and analysis procedures for use in routine design practice. The federal government should co-ordinate the existing programmes that address this need: those in the Department of Defence; the General Services Administration; the Defence Threat Reduction Agency; and NIST. Affected Standards: ASCE-7, AISC Specifications, and ACI 318. These standards and other relevant committees should draw on expertise from ASCE/SFPE 29 for issues concerning progressive collapse under fire conditions. Model Building Codes: The consensus standards should be adopted in model building codes (i.e. the International Building Code and NFPA 5000) by mandatory reference to, or incorporation of, the latest edition of the standard. State and local jurisdictions should adopt and enforce the improved model building codes and national standards based on all 30 WTC Recommendations (2005). The codes and standards may vary from the WTC Recommendations, but satisfy their intent.
b. A robust, integrated predictive capability should be developed, validated, and maintained to routinely assess the vulnerability of whole structures to the effects of credible hazards. This capability to evaluate the performance and reserve capacity of structures does not exist and is a significant cause for concern. This capability would also assist in investigations of building failure – as demonstrated by the analyses of the WTC building collapses carried out in this Investigation. The failure analysis capability should include all possible complex failure phenomena that may occur under multiple hazards (e.g. bomb blasts, fires, impacts, gas explosions, earthquakes, and hurricane winds), experimentally validated models, and robust tools for routine analysis to predict such failures and their consequences. This capability should be developed via a co-ordinated effort involving federal, private sector, and academic research organizations in close partnership with practicing engineers.
NIST WTC Recommendation 2.
NIST recommends that nationally accepted performance standards be developed for: (1) conducting wind tunnel testing of prototype structures based on sound technical methods that result in repeatable and reproducible results among testing laboratories; and (2) estimating wind loads and their effects on tall buildings for use in design, based on wind tunnel testing data and directional wind speed data. Wind loads specified in current prescriptive codes may not be appropriate for the design of very tall buildings since they do not account for building-specific aerodynamic effects. Further, a review of wind load estimates for the WTC towers indicated differences by as much as 40 % from wind tunnel studies conducted in 2002 by two independent commercial laboratories. Major sources of differences in estimation methods currently used in practice occur in the selection of design wind speeds and directionality, the nature of hurricane wind profiles, the estimation of ‘component’ wind effects by integrating wind tunnel data with wind speed and direction information, and the estimation of ‘resultant’ wind effects using load combination methods. Wind loads were a major factor in the design of the WTC tower structures and were relevant to evaluating the baseline capacity of the structures to withstand abnormal events such as major fires or impact damage. Yet, there is lack of consensus on how to evaluate and estimate winds and their load effects on buildings.
a. Nationally accepted standards should be developed and implemented for conducting wind tunnel tests, estimating site-specific wind speed and directionality based on available data, and estimating wind loads associated with specific design probabilities from wind tunnel test results and directional wind speed data.
b. Nationally accepted standards should be developed for estimating wind loads in the design of tall buildings. The development of performance standards for estimating wind loads should consider: (1) appropriate load combinations and load factors, including performance criteria for static and dynamic behaviour, based on both ultimate and serviceability limit states; and (2) validation of wind load provisions in prescriptive design standards for tall buildings, given the universally acknowledged use of wind tunnel testing and associated performance criteria. Limitations to the use of prescriptive wind load provisions should be clearly identified in codes and standards.
The standards development work can begin immediately to address many of the above needs. The results of those efforts should be adopted in practice as soon as they become available. The research that will be required to address the remaining needs also should begin immediately and results should be made available for standards development and use in practice. Affected National Standard: ASCE-7. Model Building Codes: The standard should be adopted in model building codes by mandatory reference to, or incorporation of, the latest edition of the standard.
NIST WTC Recommendation 3.
NIST recommends that an appropriate criterion be developed and implemented to enhance the performance of tall buildings by limiting how much they sway under lateral load design conditions (e.g. winds and earthquakes). The stability and safety of tall buildings depend upon, among other factors, the magnitude of building sway or deflection, which tends to increase with building height. Conventional strength-based methods, such as those used in the design of the WTC towers, do not limit deflections. The deflection limit state criterion, which is proposed here is in addition to the stress limit state and serviceability requirement; it should be adopted either to complement the safety provided by conventional strength-based design or independently as an alternate deflection-based approach to the design of tall buildings for life safety. The recommended deflection limit state criterion is independent of the criterion used to ensure occupant comfort, which is met in current practice by limiting accelerations (e.g. in the 15 to 20 milli-g range). Lateral deflections, which already are limited in the design of tall buildings to control damage in earthquake-prone regions, should also be limited in non-seismic areas.*
[ * F-22 Analysis of baseline performance under the original design wind loads indicated that the WTC towers would need to have been between 50 % and 90 % stiffer to achieve a typical drift ratio used in current practice for non-seismic regions, though not required by building codes. Limiting drift would have required increasing exterior column areas in lower stories and/or significant additional damping.]
Affected National standards: ASCE-7, AISC Specifications, and ACI 318. Model Building Codes: The standard should be adopted in model building codes by mandatory reference to, or incorporation of, the latest edition of the standard.

EU Commissioner Connie Hedegaard in Dublin – Hot Air ?
At lunchtime on Friday, 29 October 2010 … European Union (EU) Commissioner, Ms. Connie Hedegaard, in charge of European Commission DG CLIMA (the new Directorate General for ‘Climate Action’) … addressed the Institute of International & European Affairs in Dublin.
While Connie’s Speech was not subject to the Europa House Rule … the Question & Answer Session, afterwards, was.
Note: IIEA’s Europa House Rule … Irish equivalent of the Chatham House Rule … ‘ When a meeting, or part thereof, is held under the Europa House Rule, participants are free to use the information received, but neither the identity nor the affiliation of the speaker(s), nor that of any other participant, may be revealed.’
.
Colour photograph of European Commissioner Connie Hedegaard, DG CLIMA (Directorate General for Climate Action), who visited Dublin recently on Friday, 29 October 2010.
Most importantly, I wanted to find out whether Europe will maintain its air of insufferable arrogance at the upcoming UNFCCC (United Nations Framework Convention on Climate Change) Cancun Summit, which will be held in December (2010) … and be excluded from critical stages in Global Climate Change Negotiations, as was the case in Copenhagen last December (2009) ??? I was not reassured that we have learned from those humbling experiences !
One small case in point … in Europe, we are still messing around with talk of limiting the rise in Global Average Temperatures to 2 degrees Celsius above Pre-Industrial Levels. However … it was demanded last year, in Copenhagen, that this rise be limited to 1.5 degrees Celsius … or lower … particularly by the Small Island Developing States (SIDS) ! Have we listened ? No ! NGO’s in Ireland … please also take note !!!
.
However ! Some good news for a change … the European Commission will produce, sometime early next year in 2011, a strategy document on ’2050 – A Low Carbon Society in Europe’ … that is just a gist of the title, so please don’t quote me … which will also contain related EU Performance Targets for 2030. 2020 is just around the corner, folks !!
Also … Climate Change Adaptation, in Europe, will be given far more of a policy emphasis. Up to recently, there has been little interest in this subject. But the truth is dawning … Mitigation is failing, and Europe is already suffering from the adverse impacts of Climate Change. Practical ways and means are now being identified, therefore, to integrate Adaptation widely into other European Union Policies and Instruments.
In 2009, the European Commission’s White Paper: ‘Adapting to Climate Change - Towards a European Framework for Action’ [COM(2009) 147 final] was published. Next year, following consultations, the Adaptation Framework will make its appearance … and will be promoted with vigour ! So I hope !!!
.
During the Question & Answer Session which followed Connie Hedegaard’s Speech, I raised the following two issues …
1. Missing from the 2009 Adaptation White Paper … the Press Releases, Speeches, and Memos, etc. on the DG CLIMA WebSite … and her Speech at the IIEA on Friday … is any serious or meaningful reference to Sustainable Human & Social Development in all of her work on Climate Action. I strongly suspect, now, that she does not fully understand the meaning of the concept … which involves far, far more than being ‘use-efficient with the earth’s resources’ !
And … would Connie ever consider acquainting herself … properly … with the EU Treaties ? She might then discover the many substantive references to ‘sustainable development’ … and none to the ‘green’ society, ‘green’ this, or ‘green’ the other !!
2. As usual, European Union (EU) Climate Change Data & Statistics were confidently presented by Connie at the IIEA … some, not a lot ! However, there is a major question mark hanging over those statistics … are they Reliable ?? At European level … the experts in the proper management of data and statistics work in EuroStat, which is located in Luxembourg. I visited, there, at the end of June 2010.
However, Europe’s Climate Change Statistical Databases are managed by the European Environment Agency (EEA), which is located in Copenhagen. Does the EEA have the required expertise to manage these Statistical Databases ? No ! Is EuroStat being excluded from making an input into the management of these Databases ? Definitely … Yes !
In question, and in serious doubt … this is the recent EEA’s European Topic Centre on Air & Climate Change (ETC/ACC) Technical Paper 2010/4: ‘Approximated EU Greenhouse Gas Inventory for 2009 – Short Report for EU-15 & EU-27′ … please examine it carefully for yourself.
ETC/ACC Technical Paper 2010/4 was the basis for the Official Statement by Connie Hedegaard, dated 2010-09-10, on the Estimates for EU Greenhouse Gas Emissions in 2009, published by the European Environment Agency (EEA) ! She said …
” The sharp drop in overall EU Greenhouse Gas Emissions last year is not a surprise seen in the light of the economic crisis. But the EU Emissions had already been falling steadily for several years before the recession hit, putting us well on track to meet or even over-achieve our Kyoto Protocol Targets. This is thanks to the armoury of policies and measures implemented over the past decade, which have succeeded in breaking the automatic link that used to mean that economic growth translated into higher Emissions. However, as the economy picks up again we can expect the drop in Emissions to level off or even be reversed temporarily. It is therefore very important that the EU and Member States continue implementing the climate and energy package and the other measures needed to meet our 2020 Targets. And of course I hope that the new strong figures also can inspire the necessary debate on how fast the EU can reach even more ambitious targets.”
.
Just to get you started … please note how the Kyoto Industrial GHG’s (HFC’s, PFC’s and SF6) have … not ! … been handled in this Technical Paper …

U.S. Consumer Organization Identifies Hazardous Plasterboards
In the United States of America, there has been a long-running saga of Hazardous Hydrogen Sulphide (H2S) Emitting Plasterboard/Drywall being installed in new housing. My U.S. cousin and his beautiful wife were crying their eyes out, here in Ireland last year, having discovered that their new home in Florida had been constructed using this plasterboard … or ‘drywall’, as it is known in the local language over there, i.e. American.
This sorry story graphically illustrates a number of important points …
- The Construction Products & Materials Industry is completely and utterly global in nature. Europe is not immune from this phenomenon !
- Within the European Single Market, proper and unqualified emphasis must be placed on the correct CE Marking of Construction Products. Unfortunately, too many European Manufacturers have not the remotest notion about what CE Marking means or involves. And … CE Marking Technical Control Systems & Procedures in European Countries are totally inadequate.
- Just as many people think nothing about stealing the intellectual property of others … so many people think nothing about Fraudulently Applying the CE Mark to unapproved construction products.
- In order to improve the situation concerning Consumer Ignorance about CE Marking … even when a manufacturer has his/her/their CE Marking in order … it is still necessary to clearly and simply demonstrate the Route of Conformity which has been taken in order to obtain the CE Mark. This is not a requirement of European Union Law … but merely a strong personal opinion based on the experience of being a technical controller for many years.
- The problem of hazardous plasterboard in buildings could also happen in Ireland … or in any other European country. It might already have happened. Beware !
- It is not acceptable that a well-established European Brand Name has engaged in this sort of ‘sharp’ practice outside Europe !! Across a large trans-national organization … it is essential that Product Quality Control is consistently at a uniformly high level.

In a CPSC (USA) Press Release #10-243, dated 25th May 2010 …
WASHINGTON, D.C. - The United States Consumer Product Safety Commission (CPSC) is releasing today the names of the plasterboard manufacturers whose plasterboard emitted high levels of hydrogen sulphide in testing conducted for the agency by the Lawrence Berkeley National Laboratory (LBNL), in California. There is a strong association between hydrogen sulphide and metal corrosion.
Of the samples tested, the top ten reactive sulphur-emitting plasterboard samples were all produced in China. Some of the Chinese plasterboard had emission rates of hydrogen sulphide 100 times greater than non-Chinese plasterboard samples.

“Homeowners who have problem plasterboard in their homes are suffering greatly”, said CPSC Chairman Inez Tenenbaum. ”I appeal to these Chinese plasterboard companies to carefully examine their responsibilities to U.S. families who have been harmed, and do what is fair and just”.
At the US-China Strategic and Economic Dialogue meetings in Beijing on 24th & 25th May 2010, U.S. officials pressed the Chinese government to facilitate a meeting between CPSC and the Chinese plasterboard companies whose products were used in U.S. homes, and which exhibit the emissions identified during the testing procedures. The Strategic and Economic Dialogue represents the highest-level bilateral forum to discuss a broad range of issues between the two nations.
The following list identifies the top 10 plasterboard samples tested which had the highest emissions of hydrogen sulphide, along with the identity of the manufacturer of the plasterboard and the year of manufacture, from highest to lowest.
- Knauf Plasterboard (Tianjin) Co. Ltd.: (year of manufacture 2005) China ;
- Taian Taishan Plasterboard Co. Ltd.: (2006) China ;
- Shandong Taihe Dongxin Co.: (2005) China ;

Last month, CPSC released the results of plasterboard emissions tests by LBNL. The studies showed a connection between certain Chinese plasterboard and corrosion in homes. In addition, the patterns of reactive sulphur compounds emitted from plasterboard samples show a clear distinction between certain Chinese plasterboard samples manufactured in 2005/2006 and other Chinese and non-Chinese plasterboard samples.
To date, CPSC has spent over $5 million to investigate the chemical nature and the chain of commerce of problem plasterboard. Earlier this year, CPSC and the U.S. Department of Housing & Urban Development (HUD) issued an Identification Protocol to help consumers identify problem plasterboard in their homes. Last month, CPSC and HUD issued Remediation Guidance to assist impacted homeowners.

‘Climate’ Politics – From 2007 Consensus to 2009 Fracture ?
The 2007 UNFCCC Climate Summit held in Bali, Indonesia, from 3rd-15th December … resulted in a strong global consensus in favour of immediate and concerted action on climate change … and a sharply worded document, the 2007 Bali Action Plan … key parts of which state …
‘ The Conference of the Parties,
Resolving to urgently enhance implementation of the Convention in order to achieve its ultimate objective in full accordance with its principles and commitments ;
Reaffirming that economic and social development and poverty eradication are global priorities ; …
Recognizing that deep cuts in global emissions will be required to achieve the ultimate objective of the Convention and emphasizing the urgency to address climate change as indicated in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change ;
1. Decides to launch a comprehensive process to enable the full, effective and sustained implementation of the Convention through long-term cooperative action, now, up to and beyond 2012, in order to reach an agreed outcome and adopt a decision at its fifteenth session, by addressing …
(a) A shared vision for long-term co-operative action, including a long-term global goal for emission reductions … in accordance with the provisions and principles of the Convention, in particular the principle of common but differentiated responsibilities and respective capabilities ;
(b) Enhanced national/international action on mitigation of climate change …
(c) Enhanced action on adaptation …
(d) Enhanced action on technology development and transfer to support action on mitigation and adaptation …
(e) Enhanced action on the provision of financial resources and investment to support action on mitigation and adaptation and technology co-operation … ‘
.
Just a few weeks later, on 12th February 2008, in New York … Ambassador John Ashe, Permanent Representative of Antigua & Barbuda to the United Nations, delivered an Important Statement on behalf of the Group of 77 & China (comprising 130 countries) … at the Thematic Debate of the U.N. General Assembly: ‘Addressing Climate Change – The United Nations and the World at Work’. Fully reflecting and supporting the Bali Action Plan, this Statement clearly set out the Climate Change Priorities for the Developing and Least Developed Countries, including the Small Island Developing States (SIDS). It included the following important extract …
‘ Climate Change as a Sustainable Development Challenge
5. Mr. President, the Group of 77 and China is of the view that discussions on climate change should be placed within the proper context of sustainable development. It is imperative that our discussion reinforces the promotion of sustainable development …
6. We must not lose sight of the fact that climate change is a sustainable development challenge. As such we should adhere steadfastly to the Rio principles, in particular the principle of common but differentiated responsibilities. We must take fully into account that poverty eradication, economic and social development are the paramount priorities of developing countries …
7. Mr. President, urgent action is needed now to fully implement the commitments under the Convention and the Kyoto Protocol, especially commitments on financing for adaptation, technology transfer and capacity building, if we are to make progress towards the achievement of the sustainable development goals of developing countries …
8. Urgent action is particularly needed on commitments, as climate change threatens the livelihoods of the very poor and vulnerable developing countries, in particular Africa, the Least Developed Countries, the Land-Locked Least Developed Countries, Small Island Developing States, and disaster prone developing countries. The G77 and China is of the view that while addressing the challenge of climate, the most affected countries and most vulnerable countries should be given adequate attention and support.
9. Developed countries Parties must take the lead in addressing the implementation gap, since the extent to which developing countries Parties can effectively respond to the challenge depends on the effective implementation by developed country Parties of their commitments relating to financing and technology transfer.’
.
The Developed Countries, i.e. those listed in Annex I of the 1992 UN Framework Convention on Climate Change, did not listen to the words of John Ashe. This helps to explain the Fracture of the 2007 Bali Consensus at Copenhagen, in December 2009 … the sharp division between the ‘have’s’ and the ‘have-not’s’ of our small planet.
Within Developed Countries … there may be a certain comfort, at an intellectual level, in linking Sustainable Development and Climate Change. However, in vulnerable Developing Countries this link is critical … where poverty eradication, and economic and social development are paramount priorities. All are ‘responsible needs’ which are clearly specified and supported by International Law. Yet, the Developed Countries persist in disregarding their legal obligations under Articles 2.3 and 3.14 of the 1997 UNFCCC Kyoto Protocol … and, more importantly, evading their historical responsibility for causing the problem of Anthropogenic Climate Change in the first place.
Closer to home, in the European Union Member States, far too much emphasis is being placed on fully exploiting the various ‘flexibility mechanisms’ within the UNFCCC Process … rather than on direct and proper compliance with their individual Kyoto Mitigation Commitments. There is little or no interest in Adaptation. Meanwhile, the reality shown by the latest analysis of observations from the World Meteorological Organization’s Global Atmosphere Watch (GAW) Programme is that the globally averaged mixing ratios of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) reached new highs in 2008 with CO2 at 385.2 parts per million, CH4 at 1797 parts per billion (ppb) and N2O at 321.8 ppb … higher than those in pre-industrial times (before 1750) by 38%, 157% and 19%, respectively !

Sustainable Climate Adaptation – The Post Copenhagen Priority !
[It was necessary to commence this post ... only after visiting India. See the first post of 2010-01-18.]
Well … we really saw it all at Copenhagen during those two long weeks in December 2009. Wasn’t it great to watch ?!? News, gossip, political ’shenanigans’ and spin … along with riots in the streets and walk-outs in the corridors … a veritable circus … an unmitigated farce !!! A crime against humanity ????
Following the UNFCCC Summit … the PEW Center on Global Climate Change, in the USA (using their own words: an independent, non-profit, non-partisan organization dedicated to providing credible information, straight answers, and innovative solutions to address climate change), offered this ‘credible information’ …
‘ A new political accord struck by world leaders at the U.N. Climate Change Conference in Copenhagen provides for explicit emission pledges by all the major economies – including, for the first time, China and other major developing countries – but charts no clear path toward a treaty with binding commitments.
The basic terms of the Copenhagen Accord were brokered directly by President Obama and a handful of key developing country leaders on the final day of the conference, capping two weeks of harsh rhetoric and pitched procedural battles that made the prospect of any agreement highly uncertain. It then took nearly another full day of tense negotiations to arrive at a procedural compromise allowing the leaders’ deal to be formalized over the bitter objections of a few governments.
… ‘
Now compare this News Article, by Satyen Mohapatra, from the Hindustan Times, New Delhi, India … dated Saturday, 9th January 2010 …
India Brought China Onboard at Copenhagen
New Delhi: Environment & Foreign Minister Jairam Ramesh, on Friday, said India had brought China onboard at Copenhagen.
“India brought China onboard at Copenhagen. The U.S. actually owes a lot to India”, he said here at an interaction.
Despite taking a leadership role during the negotiations, Ramesh said, the Chinese were not ready to talk directly with the US, but always as part of the BASIC (Brazil, South Africa, India and China) Group.
Recounting how the Accord was reached at Copenhagen, Ramesh said it was “floundering on three issues: whether the goal of arresting greenhouse gas (GHG) emissions by 2050 should be expressed in terms of temperature or emission reduction or concentration of GHG in the atmosphere; what would be the international monitoring and verification regime for the mitigation actions of the BASIC countries; and whether the Accord would be legally binding”.
“We got 2.5 out of three”, he added.
And then … consider the opening of a statement by Bruno Rodriguez Parrilla, Cuban Minister for Foreign Affairs, at the last session of the Climate Summit on Friday, 18th December 2009 …
Mr. Chairman:
It has been four hours since President Obama announced an agreement that does not exist. He is disrespecting the international community and behaving as an imperial master.
The document that you, Mr. Chairman, repeatedly claimed that did not exist is showing up now. We have all seen drafts surreptitiously circulated and discussed in secret meetings, outside the rooms where the international community has been transparently negotiating through its representatives.
As it happens, Mr. Chairman, the non-existent document does exist. I deeply regret the way you have conducted the works of this conference.
I can anticipate that the delegation from the Republic of Cuba has decided not to accept the declaration you are introducing. I do not need any additional consultation in any other framework or format; therefore, I declare that at this conference there is no consensus on this document.
I add my voice to that of the representatives of Tuvalu, Venezuela and Bolivia. Cuba considers the text of this apocryphal draft extremely insufficient and inadmissible. The unacceptable goal of 2 degrees Centigrade would have incalculable catastrophic consequences, particularly for the small island nations. It would also have a grave impact on numerous species of the biodiversity.
The document that you are unfortunately introducing contains no commitment whatsoever on the reduction of greenhouse gas emissions.
I am aware of the previous drafts, which again through questionable and clandestine procedures, were negotiated in small groups and which at least made reference to a 50% reduction by 2050. I have here with me those previous drafts that it would be worthwhile making public in this room and releasing to the media and the representatives of the civil society.
The document that you are introducing now leaves out precisely those already meagre and insufficient key phrases contained in those drafts. This document does not guarantee, in any way, the adoption of minimal measures conducive to the prevention of an extremely grave catastrophe for the planet and for human beings.
To Cuba, the content of this document is incompatible with the universally recognized scientific criterion which deems it urgent and unavoidable to ensure at least a 45% reduction of emissions by the year 2020, and no less that 80% or 90% by 2050.
This shameful document that you bring to us is also insufficient and ambiguous with regards to the specific commitment of the developed countries to reduce emissions even when they are responsible for the global warming resulting from the historic and current level of their emissions, and it is only fit that they undertake meaningful reductions right away. This document fails to mention any commitment by the developed nations.
…
Confused ? Depressed ?? Frustrated ???
.
Some Observations from the 2009 UNFCCC Copenhagen Climate Summit:
1. The 2009 Copenhagen Accord is a voluntary political agreement among a small number of countries … an arrangement of convenience. It has no status within the international framework of the 1992 Convention on Climate Change and the 1997 Kyoto Protocol … it is a non-document. It does, however, provide political cover for Brazil, South Africa, India and China (BASIC) … along with the USA … whose politicians have no wish to be bound by legally binding, meaningful GHG Emission Reduction Targets benchmarked back to 1990 levels … most especially, GHG Emission Reductions which would be stringently and independently verified by competent external agencies. The Accord also has the potential, within it, to derail the entire UNFCCC process.
The Accord is not, therefore, being presented on this WebSite.
2. The Developed Countries (i.e. the 1992 UNFCCC Annex I Countries) demonstrated that they had a small understanding of, but very little sympathy for, the concepts of ‘equity’, ‘fairness’, ‘historical responsibility’ and ‘climate justice’.
3. It is now clear that the European Union’s Climate Change Targets of (i) a maximum 2 degree Celsius rise in global temperature is too high … a maximum 1.5 degree Celsius rise should be the target, with an essential reference to a ‘safety factor’ in all calculations … and (ii) a 20% Greenhouse Gas (GHG) Emission Reduction by 2020 is far too low. The time for playing games with numbers is over … GHG Emission Reductions by the EU Member States should be open to stringent and independent/external verification … not just by the European Commission (which is insufficient, on its own, in this particular case) … but also by competent indigenous agencies in the BASIC Group of Countries. To heal the rifts at Copenhagen … greater openness and transparency is required from Europe !!
Spinning of EU GHG Emission Reduction Performance by the European Environment Agency (EEA) … to make it appear that Europeans are doing more, and better, than we actually are … should be firmly knocked on the head, i.e. forbidden !
And in Ireland, to bring this subject closer to home, we urgently need to find another home … one central location, properly managed … for the relevant/related GHG Databases currently held by the Environmental Protection Agency (EPA) and Energy Ireland (SEI). Here … let us recall a pertinent extract from the European Union Treaties … ‘statistics shall conform to impartiality, reliability, objectivity, scientific independence, cost-effectiveness and statistical confidentiality’. This issue has been discussed in previous posts. So … say no more !!!!
4. Developed Countries continue to show a feigned interest in Climate Change Adaptation. Too much of their energies and resources are still being directed at fully exploiting the ‘flexibilities’ in meeting Kyoto GHG Emission Reduction Targets. They are wealthy enough … and they believe (mistakenly) that they possess all of the institutional capacities necessary to deal with any adverse impacts caused by Climate Change, including Variability and Extremes. We have found recently in Ireland, however, during the National Major Flood and Snow Emergencies that we certainly do not have these capacities. If anything, we now know that the relevant institutions in this country are incompetent, disorganized and dysfunctional.
Bearing in mind that the minimum life cycle for a Sustainable Building (just to take one important component of the Built Environment) is 100 years … the abject failure to reach a legally binding consensus agreement at Copenhagen … means that National Adaptation Strategies must now be planned and formulated … urgently … on the basis of, at the very least, a 3-4 degree Celsius rise in global temperature.
.
What is Climate Change Adaptation ?
This encompasses, generally, all actions to reduce the vulnerability and strengthen the resilience of the Human Environment, including ecological and social systems, institutions and economic sectors … to present and future adverse effects of climate change and the impacts of response measure implementation … in order to minimize the threats to life, human health, livelihoods, food security, assets, amenities, ecosystems and sustainable development.
Built Environment Climate Change Adaptation, more specifically, means … reliably implementing policies, practices, projects and institutional reforms in the Built Environment … with the aim of reducing the adverse impacts and/or realizing the benefits directly/indirectly associated with climate change, including variability and extremes … in a manner which is compatible with Sustainable Human and Social Development.
Many opportunities can arise from Adaptation.
.
Why is a Sustainable Approach to Climate Change Adaptation Necessary ?
As an example and very briefly …
In Ireland, it has been proposed as an Adaptation Project … to divert water from the Shannon, a very large river in the west of the country … to Dublin, the capital city, which is located on the east coast … in order to deal with the expected shortage of water which will be caused by Climate Change in the medium term … among other factors.
“Fine”, you might say … and you may later add: “an interesting civil engineering infrastructural project”, as you visualize, in your mind’s eye, impressive Roman Aqueducts in the south of France or outside Rome.
BUT … if you then consider that there are no residential water charges in Dublin (so the concept of water conservation is almost unknown among householders); water supplied to houses in the Dublin Region are not yet metered (so there is no urgency to locate and deal with water leakage inside the private property boundary); there are enormous unintended losses, i.e. leaks, from the public potable water distribution system (approximately 40% even in the good times, and recently well in excess of 60% following the National Snow Emergency !); there are no requirements in our National Building Regulations to harvest any rainwater in any buildings or on any hard surfaces in the vicinity of those buildings … and, finally, Sustainability Impact Assessment (SIA) is not yet a standard procedure, at any level, within National and Local Authorities Having Jurisdiction.
So … just how ‘sustainable’, in reality, is the Shannon-Dublin Water Diversion Scheme as a Climate Change Adaptation Project ???

Older People in Emergencies – Action & Policy Development (II)
In 2008, the World Health Organization (WHO) Report: ‘Older People in Emergencies – Considerations for Action & Policy Development’ was published.
The following are short extracts from that Report …
Older People
Until recently, older peoples’ needs in disasters and conflicts were addressed only by broader adult health and humanitarian programmes. This has changed, as several recent emergencies highlighted this population’s vulnerabilities. Of the 14,800 deaths in France during the 2003 heat wave, 70% were people over 75 years of age. Of the estimated 1,330 people who died in the wake of Hurricane Katrina, most were older people. In Louisiana, 71% of those who died were older than 60 years; 47% of this group were over 77 years old. Worldwide, the United Nations High Commissioner for Refugees (UNHCR) has estimated that older people make up 8.5% of the overall refugee population, and in some cases comprise more than 30% of caseloads. In 2005, approximately 2.7 million people over the age of 60 were living as refugees or internally displaced persons.
Globally, the proportion of older people is growing faster than any other age group. In 2000 one in ten, or about 600 million, people were 60 years of age or older. By 2025, this figure is expected to reach 1.2 billion people, and in 2050 around 1.9 billion. In developing countries, where 80% of older people live, the proportion of those over 60 years old in 2025 will increase from 7% to 12%. Moreover, life expectancy at birth has increased globally from 48 years in 1955 to 65 in 1995, and is projected to reach 73 in 2025. By 2050, people over 80 years old are expected to account for 4% of the world’s population, up from 1% today.
Disability & Older People
Worldwide, it is estimated that more than 80% of the disabled population lives in developing countries, where the prevalence of disability is approximately 20%. That rate is expected to increase dramatically as populations age. By 2050 in India, the incidence of disability is expected to jump by 120%, in China by 70% and in sub-Saharan Africa by 257%.
Emergency Planners must consider these trends, because poor health and reduced mobility increase the risk of serious injury and illness in disasters. Older people have sustained more injuries in disasters than other groups because of functional limitations such as poor balance, muscle weakness and exhaustion. Older people have higher rates of coronary heart disease, diabetes, stroke, cancer, respiratory diseases and rheumatism. A study in China found that 74% of those over 80 years old had chronic diseases, 1.5% were physically disabled, and 3.46% had Alzheimer’s disease. In Iraq, more than half of 340 older people surveyed by HelpAge International had chronic joint and bone problems, hypertension, heart problems, diabetes and reduced eyesight and hearing. In West Darfur, Sudan, 34% of surveyed refugees 50 years of age and over were disabled, 27% could not move without help and 19% had severely impaired vision; while 61% reported chronic diseases that required specialized treatment and/or medicines that were not available.
Objective 1: Increase Visibility and Raise Awareness among Health Agencies and Humanitarian Organizations about Older Peoples’ Needs and Priorities in Emergencies.
- Mainstream and integrate issues related to older people and emergencies into existing policies and guidelines (i.e. emergency medicine, nutrition, protection, gender-based violence, participatory assessments and programming). Include plans for older people in national policy and guideline documents.
- Highlight the need to assist and protect older people as well as their capacities and contributions in rebuilding affected communities.
- Develop inter-agency efforts to identify gaps, develop practice guidelines and provide training and education.
- Promote better practice policies and documents among all stakeholders.
- Collaborate with funders to increase humanitarian assistance to older people based on needs assessments and reflect these in funding proposal criteria.
- Involve older people in developing emergency management activities to increase their visibility and ensure their needs are taken into account, for example, in shelter plans and locations.
Objective 2: Develop Essential Medical and Health Resources for Older People in Emergency Practices.
- Identify and include essential medicines for older people in emergency kits. Include medicines for chronic diseases and other illnesses common among this social group.
- Develop disability aid packages with equipment such as eyeglasses and walking sticks.

- Ensure that nutritional guidelines for food distribution suitable for older people are integrated into health planning and response plans.
- Ensure local development of guidelines for feeding older people, using locally available foods to the extent this is possible where populations depend on external food aid.
- Implement gender-based analyses in planning and programme design to account for differences between older men and women in terms of both health needs and access issues.
Objective 3: Develop Emergency Management Policies and Tools to Address Older Peoples’ Health-Related Vulnerabilities.
- Integrate older peoples’ health needs and related issues into assessment tools and practices.
- Develop community-based tools using disaggregated data to identify vulnerable older people. Include formats to identify chronic health conditions, disabilities and nutritional needs.
- Develop procedures to identify hidden and stay-behind older people.
- Develop standardized tools to assess support needs of older people, including inter-generational and community care options.
- Develop age-friendly standards and guidelines so that service and care environments are accessible to older people with disabilities.
- In collaboration with older people, their families and communities, develop personal and household preparedness kits in areas of predictable disasters.
- Collaborate with communities in identifying and implementing community-based home care and support strategies which may reduce older peoples’ isolation and vulnerability during crises.
- Develop guidelines and evacuation plans that include mechanisms to identify and transport frail, disabled and older people with special medical conditions. Identify procedures to ensure adequate care and treatment as necessary.
- Develop guidelines to ensure safe and adequate treatment of older people in evacuation centres and refugee camps.
- Ensure that health facilities have feasible plans to care for older people during disasters and humanitarian crises.
- Develop monitoring and evaluation tools to measure the performance of health care services and humanitarian interventions targeting older people. These measures should be integrated into existing monitoring and evaluation procedures where possible.
Objective 4: Ensure that Older People are Aware of and Have Access to Essential Emergency Health Care Services.
- Use established assessment tools to identify and locate frail and disabled older people and those with chronic diseases and special medical conditions, as well as older caretakers of orphaned children.
- Ensure that assessments are participatory and target all older populations. Assessments should include information on health conditions, social support needs, caretaking responsibilities and available means to meet basic living needs, including access to food and health services, treatment and medicines.
- Ensure that assessments are coordinated across primary health care, rehabilitation, long term care and social services to meet the needs of older people.
- Implement outreach services and referral mechanisms to identify and ensure care for hidden or stay-behind older people.
- Coordinate primary health care, rehabilitation, long-term care and social services to establish system referral mechanisms that older clients may require.
- Assess and organize training for health staff to ensure knowledge of geriatric nutritional, health and medical care needs.
- Establish information programmes to educate older people, families and caregivers about nutritional needs, medical conditions and health care options.
- Use disaggregated data to assess services by age and gender.
Objective 5: Provide Age-Sensitive and Appropriate Health and Humanitarian Services to Maintain Older Peoples’ Health.
- Ensure that equitable access to shelter, clothing, food and sanitation prevent deterioration of health through integrated individual assessments and referrals to health and humanitarian agencies.
- Ensure that age-friendly practices are used to promote services to older people with disabilities.
- Provide access to appropriate health care, including medicines for chronic diseases and disability/restorative aids.
- Collaborate with communities in identifying community-based home care and support options for frail and disabled older people.
- When appropriate and feasible, develop mobile clinics to extend health services to older people living in remote locations.
- Implement mechanisms to assess nutritional balance and ensure access to supplementary food programmes when appropriate, taking into account that many older people also care for children. Provide education on food preparation using supplementary or locally available foods.
- Ensure that protection needs of older people are integrated into programming (e.g. social welfare or community services) to identify persons at risk and prevent abuse and exploitation.
- Undertake monitoring to assess continuing effectiveness of services to older people.
- Use disaggregated data to assess efficiency of implemented activities by age and gender.
Objective 6: Promote Cross-Sectoral Planning and Co-Ordination to Raise Awareness of Older Peoples’ Needs in Crises and Reduce Their Risk of Marginalization and Deteriorating Health in Emergencies.
- Raise awareness among agencies and organizations concerning physical and health issues specific to older people and of ways to adapt basic need support to their requirements (e.g. supplementary food rations, livelihood needs and impacts of protection issues on older peoples’ physical and psychological health).
- Where possible, include older people in planning and programming committees to increase their visibility and ensure their needs and priorities are integrated.
- In coordination with appropriate partners, establish community self-help groups to facilitate community care for more vulnerable older people.
- Recognize self-sufficiency as key to maintaining health and encourage the inclusion of older people in training programmes, income-generation schemes, and community development projects.
- Establish older peoples’ committees to facilitate self-advocacy and communication with authorities and ministries of health to increase access to existing services and entitlements.
Objective 7: Build Institutional Capacity and Commitment towards Ensuring the Health and Safety of Older People in Emergencies.
- Integrate cross-cutting health emergency management issues into global/regional/country strategic plans.
- Promote inter-agency and cross-sectoral consultation on cross-cutting policy and programming issues to build consensus, commitment and capacity to respond to older peoples’ needs in disasters and humanitarian crises.
- Collaborate with ministries of health to establish mandates and legislation ensuring the provision of care to older people; apply a human rights framework to these issues.
- Collaborate with ministries of health to develop options to increase older peoples’ access to affordable health care services, including the implementation of subsidized medical and medicine programmes.
- Advocate for enhanced funding and humanitarian assistance to older people in emergencies and conflicts. Encourage funding agencies to recognize older people as a priority.
- Develop frameworks to promote participatory, transparent and accountable processes to advance the needs of older people.
- Develop sustainable mechanisms to maintain advocacy and consultation of older people within the health care-system. Establish and involve advocacy committees in the planning, implementation and evaluation of emergency management practices when appropriate, for example regarding the design of community shelters that may be accessed by older disabled people.
Objective 8: Strengthen the Capacity of Ministries of Health and Health Care Systems to Meet the Needs of Older People in Emergencies.
- As required, integrate the medical and nutritional needs of older people into local public health and emergency preparedness and response strategies.
- Develop strategies to ensure that existing health care systems develop capacity (infrastructure and knowledge) to meet the increasing proportion of older people who will be impacted by disasters in the future, taking into account medical, disability and mental health needs, including dementia and Alzheimer’s disease.
- Collaborate with communities in identifying community-based home care and support strategies for older people as an option to reduce older peoples’ isolation and vulnerability to disasters.
- Collaborate with communities to develop and maintain disaster reduction committees. Assist in the implementation of strategies to strengthen community support to older people and reduce their levels of risk during disasters (e.g. development of community emergency response teams or mutual assistance groups among more vulnerable older people).
- Integrate older peoples’ needs into exercise designs and facilitate the dissemination of lessons learned.
- Develop performance frameworks and monitoring mechanisms to assess medical response systems and older peoples’ access to specialty care in emergencies.
Objective 9: Develop Mechanisms to Ensure Continuing Development and Exchange of Expertise as these Relate to Older People in Emergencies.
- Develop and provide ongoing training and education to staff on the needs and priorities of older people, including responsibility to include this population in planning and policy development.
- Integrate issues related to older people in emergencies into relevant university curricula.
- Undertake comparative research to assess the health status (including access to assistance) of older people in emergencies vis-à-vis other age groups.
- Undertake research to address demographic shifts and the increasing proportion of older people in disasters as this relates to health care and infrastructure/facility development.
- Ensure emergency preparedness and response considerations are integrated into relevant services and institutions (e.g. facilities caring for frail and disabled older people are required to develop and practice evacuation and emergency care plans).
Objective 10: Promote Active Ageing as a Strategy to Reduce Vulnerability and Develop Resiliency to Disasters.
- Promote a wider understanding among ministries of health and humanitarian organizations of the economic and social factors contributing to the vulnerability of older people, including issues related to livelihoods, inter-generational dependence and social pension.
- Develop policies that recognize active ageing and resiliency as facilitating older peoples’ capacity to prepare for, cope with and respond to the affects of disasters and conflicts.
- Include a life course perspective that recognizes health promotion and prevention of disease and disability.
- Support cross-sectoral forums and activities which link the risks of older people in emergencies to frameworks for livelihoods, protection and gender-based equality, health promotion and social pension.
- Collaborate with relevant organizations to mainstream the health needs of older people into existing humanitarian programmes addressing shelter, nutrition, livelihoods, protection and gender-based violence.
- Develop information campaigns and encourage media to highlight both the needs and capacities of older people and to increase their visibility.
- Collaborate with funding bodies to integrate active ageing as a criterion in funding proposals targeting older people.

‘Feeling’ the Violent Earthquake in Abruzzo, Italy ?!?
Exactly a week ago … in the early hours of Monday morning (03:32 hrs local time), 6th April 2009, a violent earthquake hit the central Italian Region of Abruzzo. The quake had a ‘magnitude’ of 6.3 on the Richter Scale … a scale developed by Charles Richter (1900-1985) during the last century, in collaboration with Beno Gutenberg (1889-1960).
The high numbers of fatalities and people injured continue, even at this time of writing … seven days later, to rise and rise. Approaching 60,000 people have been left homeless. It will take many, many years to restore buildings … and much longer than that to restore the delicate social fabric of local communities.
It is a remarkable joy to experience the culture, and live among the people of one such small community in the centre of Italy … Amandola (≈ 4,500 inhabitants), which is a typical hilltop town located approximately 70 Km north of L’Aquila (≈ 67,000 inhabitants), capital of the Abruzzo Region.

Earthquakes between 6.1 and 6.9 on the Richter Scale regularly cause damage in areas up to 100 Kilometres away from the ‘epicentre’ … that point on the earth’s surface located vertically above the place deep within the Earth where the quake originated.
To put local news reports into some context … accurate measurement of dramatically increased levels of natural radon activity in soils, allied with a good understanding of local geology and seismology, can be an important, although not 100% reliable, indicator of what is happening deep underground. Unfortunately, and unlike in Ireland, radon protection of buildings is not taken seriously in Italy … so, not much attention would have been paid to what anybody said about radon activity in the soils around L’Aquila before the ‘big one’ hit !
Tremors from an earthquake, or trembling vibrations, can be felt strongly far away from an epicentre. I know, because I was in Amandola last Monday morning.
To be involved in Earthquake Resisting Design is one thing … I am very comfortable with technical issues, facts, concepts, building products, etc. To become intimate, however, with the ‘reality’ of a mother of an Earthquake is altogether different !
Jerked awake in those early hours … the building was rocking, not just swaying. Before reaching full consciousness … too much had already happened. If the building had collapsed, I would never have known what hit me. But, it didn’t … and there was no internal damage or cracking.
I don’t know why … but, I went back to sleep again.
Just after 08.00 hrs (local time), phone texts began to arrive from Ireland … “was everybody safe ?”. Something ‘big’ must have happened during the night. I rushed to put on the television news … forget about SKY NEWS, CNN, BBC and that miserable, no-good, laughable excuse for an ‘impartial, balanced and fair’ news service FOX NEWS … the best coverage … and continuous coverage … was on the Italian TV Stations.
Tragic scenes … of historical buildings destroyed … expected, because they would not be of modern (reinforced concrete or steel) construction … and, far many more than should be the case, of modern buildings seriously damaged or collapsed like a plate of pancakes … somewhat expected, because of inadequate technical controls over building design and construction in many parts of the country.
[Similar scenes of modern, 'tofu' construction could be witnessed after the Major Earthquakes in Central China, beginning in May 2008.]
Later that morning, I inspected an historical building which I had recently restored … and where I had incorporated earthquake resisting features. Relief, relief, relief … not a single crack.
Travelling back to Rome by car that afternoon, fleets of emergency response vehicles moved swiftly in the opposite direction towards the Earthquake Zone …
