[ EICT’s = Electronic, Information & Communication Technologies ]
2014-10-13:Electronic, Information and Communication Technologies have rapidly become an essential feature of the Built, Social and Economic Environments; they are everywhere. During a fire incident, however, these e-Technologies serve a function which is critical for the safety of all building users and firefighters, property protection, minimizing environmental damage, and sustainability. They must, therefore, have a user interface which is Accessible for All … from both ends.
This is a requirement of International Law … and an unambiguous National Requirement (expressed in the form of law and/or mandatory administrative provisions) in those jurisdictions which are States Parties to the United Nations Convention on the Rights of Persons with Disabilities (CRPD).
There is no European Standard (EN) on e-Technology Accessibility … and, in the European Union (EU), a coherent approach to the accessibility of even a modest range of EICT’s has not yet even been developed.
.
Electronic, Information and Communication Technologies (EICT’s)must comply with Section 508 of the United States Rehabilitation Act Amendments of 1998 … or with a suitable Standard/Guidance Document of another country which details an equivalent level of e-Accessibility performance.
U.S. Section 508 covers the following range of e-Technologies:
Software Applications & Operating Systems (1194.21) ;
Web-based Intranet and Internet Information and Applications (1194.22) ;
2014-08-28: Earlier this month … the final straw … as I caught up on a ‘piece’ in McGraw Hill’s Architectural Record … which reproduced an original, intriguing article from designMENA.com, posted on 12 August 2014, by Nick Ames …
Rebel Architects Star In New TV Show
Qatar-based broadcaster Al Jazeera is to show a series of films focusing on radical architects from Pakistan, Brazil, Nigeria, Spain, Palestine and Vietnam. The series – entitled ‘Rebel Architecture’ – focuses on architects using design to confront urban, environmental and social problems in their communities.
Dan Davies, producer of the series, said: “We couldn’t help noticing that despite all the problems afflicting humanity, many of which architecture uniquely has the ability to assist and even solve, most of the mainstream and architectural press celebrates the aesthetics of huge iconic projects, marvelling at insanely complicated ways to fold giant sheets of metal.”
“As we face issues from floods and natural disasters to an explosion of urban populations, soaring inequality and displacement through conflict, architecture seems wholly absent. So we wanted to look beyond the discussion of the aesthetics of Star-chitecture and see what architects outside the mainstream are doing.”
The six-part series, which starts on 18 August, begins with a film documenting the work of Spanish architect Santiago Cirugeda, who uses his knowledge of planning law to occupy abandoned properties and to build structures on unused land.
It also features Pakistani architect Yasmeen Lari, who designs disaster relief shelters and Eyal Weizman, professor of spatial and visual cultures at Goldsmiths University, who explores the way the built environment is used as an instrument of occupation.
In Vietnam, the series follows Vo Trong Nghia, whose projects focus on open spaces and sustainable design, while in Nigeria, Kunlé Adeyemi has designed floating buildings to solve issues of flooding and overcrowding.
The final episode explores Rocinha, the largest favela in Brazil, with builder Ricardo de Oliveira, and master planner Luis Toledo.
“The rebel architects have to push boundaries, but they must also look beyond their own buildings,” said Davies. “They start by looking at the wider context in which they live – be it Spain hit by the financial crisis, or Pakistan ravaged by floods – and work out how they can change the status quo with architecture.”
.
I SAY …
Shouldn’t every Architect be concerned about the issues raised in Nick’s article ? And if not … why not ??
Architecture is a wide and complex field of human creative, artistic and scientific endeavour. Yet in the international and national media, both mainstream and architectural … it does appear, as presented, to be narrowly confined to the “aesthetics of huge iconic projects”, and “insanely complicated ways to fold giant sheets of metal”. And the various media continue to focus on and enthusiastically applaud the current, outrageous phallic skyscraper contest in, for example, the Arab Gulf Region, China and South-East Asia … a contest which is actively promoted by such international organizations as the US-based Council on Tall Buildings & Urban Habitat. [ I might add … with entirely insufficient attention being paid to fire safety, resilience and sustainability in those Super-Tall Buildings !! ]
If Santiago Cirugeda, Yasmeen Lari, Eyal Weizman, Vo Trong Nghia, Kunlé Adeyemi, Ricardo de Oliveira, and Luis Toledo are indeed Rebels … [ I would argue that they most definitely are not ] … and each one is working in isolation … then we must urgently instigate a Revolution …
Creative Architecture In Context !!
PRINCIPAL BARRIER …
The Institutional Framework of Today’s Conventional Architecture … typically developed to promote and protect a 19th Century Model of Architectural Practice … exerts a powerful stranglehold over the architectural profession and the schools of architecture in many countries. It is no longer ‘fit for purpose’ in the 21st Century !
Here in Ireland … a few days before reading the Nick Ames article … I attended a long Extraordinary General Meeting of the Royal Institute of the Architects of Ireland (RIAI) … called by 10 Institute Members to demand urgent, concerted action from the Institute’s Council in response to the new and very flawed Building Control Amendment Regulations (Statutory Instruments Nos.9 & 105 of 2014), which came into effect from 1 March 2014.
Far from being an enlightening and pleasurable occasion … for many small reasons, it was annoying and frustrating. The biggest reason of all, however, was that I saw no evidence whatever that either Council or the Membership understands the simple, fundamental truth that … self-regulation/self-certification does NOT work !
Refer back to my previous post.
The General Public in Ireland … also known as ‘The Long-Suffering Consumer’ … does not trust the Medical and Legal Professions to self-regulate, despite the vociferous protestations from both that their internal regulatory systems are packed-packed-packed with civilians. Yes … ‘selected’ civilians !
That particular evening in the Davenport Hotel, Dublin … the RIAI’s Extraordinary General Meeting (EGM) went nowhere … aided and abetted by Council Members at the head table. It was interesting to note that none of the 10 Institute Members who had called the meeting had a seat at that same table.
As we exit the Profound Economic Crisis following the Extravagant Celtic Tiger Years … and coldly look around us … we witness an architectural profession lost in a contextual wilderness – urban, environmental and social – while fumbling around in a legal and political maze. And, every day, we experience a sprawling, ugly, depressing and unsustainable built environment which is engaged in a sad and brutal conflict with nature.
It has taken at least a generation … but the RIAI has directly overseen the slow and progressive dilution of what it means to be an Architect in Ireland.
2014-05-16: Anybody with even the slightest interest in the Future Development of Fire Engineering Design, and Structural Fire Engineering in particular, should pay attention to the proceedings of an upcoming CIB/NIST Workshop, which will be held on 21-22 May 2014, at the NIST Campus in Maryland, USA …
It is essential to read 3 White Papers … produced by three separate teams of experts, contracted by NIST, in advance of the Workshop … to get a ‘real’ flavour of how discussions may, or may not, develop next week. All three papers are available to download from the NIST WebSite (and the links below). I suggest that you get your hands on them … ASAP !
After reading these 3 NIST White Papers … I was not surprised by the large number of ‘unknowns’, or the enormous gaps in our ‘knowns’ …
Taken in whole and all together, however, the three documents are a public confirmation that today’s general practice of Fire Engineering is more akin to that of mid-19th Century Alchemy. Blinkered practitioners are isolated from the building design process … because they have no understanding of that process, and have no means of effective communication with the many other design disciplines involved. And minimal, i.e. ‘cost-effective'(?), compliance with the limited and inadequate fire safety objectives in current building codes/regulations is widely regarded as the one and only target for their efforts … a minor one compared to the fundamental, long-term target of realizing a Safe, Resilient and Sustainable Built Environment for All. At the same time, frontline fire service personnel are forced to operate on shoestring budgets … and, when a fire emergency inevitably occurs, they are regarded as nothing more than an expendable resource.
!! Structure … Does Not A Building Make !!
Some comments on the 3 NIST White Papers …
A. The Papers contain a number of important technical errors:
A similar Introduction in two of the Papers refers only to the 2005 NIST Report (NCSTAR 1) on the 9-11 Collapse of WTC Buildings 1 & 2 in New York City, which contained 30 Recommendations. However, NIST published a later Report in 2008 (NCSTAR 1A) on the Collapse of WTC Building 7, which contained a further 13 Recommendations … 1 new, and 12 revised/updated from the earlier 2005 Report.
There is a reference in one of the Papers to a 1989 European Directive on Construction Products (89/106/EEC), and as later amended. This Directive was repealed, in 2011, by Article 65 of the new European Union (EU) Regulation No.305/2011 on Construction Products. Unlike a Directive, a Regulation is addressed directly to the EU Member States, and does not permit any flexibility with regard to national implementation. Annex I of Regulation 305/2011 sets out 7 Basic Requirements for Construction Works:
– Mechanical resistance and stability ;
– Safety in case of fire ;
– Hygiene, health and the environment ;
– Safety and accessibility in use ;
– Protection against noise ;
– Energy economy and heat retention ;
– Sustainable use of natural resources.
Concerning fire safety in buildings … it is incorrect to state, or even suggest, that only the second Basic Requirement is relevant … a building must satisfy all of the Basic Requirements taken together, i.e. the 7 Basic Requirements are inter-dependent.
B. Having carefully read the Papers … none of the expert teams appear to have paid any attention to any of the NIST Recommendations, in either the 2005 or the 2008 Reports ! Note well that two separate series of posts on both sets of NIST Recommendations have been carried here on this Technical Blog.
C. If we have learned anything from the WTC 9-11 Building Collapses, it is that the Fire Engineer must be able to communicate effectively with other mainstream building design disciplines … especially ‘ambient’ structural engineers who speak the language of Structural Reliability, Limit State Design and Serviceability Limit States. The Fire Engineer must also become an active participant in the creative, trans-disciplinary process of design. These issues have not been seriously considered in any of the Papers.
D. All of the Papers lack a common and precise starting point … relevant structural fire engineering concepts are either not defined or badly defined … and the ‘dynamic, complex architectural interaction between a building’s structure and fabric under conditions of fire’ requires immediate and urgent investigation …
Structural Reliability
The ability of a structural system to fulfil its design purpose, for a specified time,
under the actual environmental conditions encountered in a building.
Structural Fire Engineering
Those aspects of fire engineering concerned with structural design for fire …
and the dynamic, complex architectural interaction between a building’s structure and
fabric, i.e. non-structure … under conditions of fire and its immediate aftermath,
including but not confined to the ‘cooling phase’.
Fire-Induced Progressive Damage
The sequential growth and intensification of structural deformation
and displacement, beyond fire engineering design parameters*, and the eventual 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.
[ *fire serviceability limit states ]
.
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 Damage and Disproportionate Damage are fundamental concepts in the Fire Engineering Design of All Buildings ! ]
.
E. It is not acknowledged in any of the Papers that the Fire Safety Objectives in Current Building Codes/Regulations are, of necessity, limited in scope … and entirely inadequate in the context of Annex I in EU Regulation 305/2011, and the long-term goal of realizing a Safe, Resilient and Sustainable Built Environment for All. Refer to the updated Scope, Aims & Objectives of CIB Working Commission 14: ‘Fire Safety’.
F. Once and for all … use of the term Fire Resistance (and any number of variations thereof, e.g. resistant, resisting, resistive, etc.) in connection with any aspect of structural performance in fire … is ridiculous ! It is roughly comparable to use of the term Fire Proof during the first half of the 20th Century.
G. Finally, for now … the current unwise focus on Crude Pass/Fail Results from the ‘standard fire’ testing of single loadbearing structural elements must evolve … must be transformed into the more detailed and precise measurement of all aspects of ‘real’ structural system performance over the full duration of a ‘design’ fire (including the cooling phase afterwards) … using a much wider range of performance monitoring equipment, e.g. short wave infra-red thermography.
.
It is no longer acceptable for Fire Engineering to exist in an isolated Twilight Zone … completely removed from the everyday realities of Mainstream Building & Construction.
2014-04-20:Traditional/Conventional Fire Engineering Practice is slowly, but inevitably, being transformed … in order to meet the regional and local challenges of rapid urbanization and climate change, the pressing need for a far more efficient and resilient building stock, and a growing social awareness that ‘sustainability’ demands much greater human creativity …
Design Target: A Safe, Resilient and Sustainable Built Environment for All
Essential Construction & Occupancy Start-Up Processes: Careful Monitoring & Reporting – Independent Verification of Performance (MRV)
.
Sustainable Fire Engineering Design Solutions:
Are Reliability-Based …
The design process is based on competence, practical experience, and an understanding of ‘real’ building performance and resilience during Extreme Man-Made Events, e.g. 2001 WTC 9-11 Attack & 2008 Mumbai Hive Attacks, and Hybrid Disasters, e.g. 2011 Fukushima Nuclear Incident … rather than theory alone.
Are Person-Centred …
‘Real’ people are placed at the centre of creative design endeavours and proper consideration is given to their responsible needs … their health, safety, welfare and security … in the Human Environment, which includes the social, built, economic and virtual environments.
Are Adapted to Local Context & Heritage* …
Geography, orientation, climate (including change, variability and severity swings), social need, culture, traditions, economy, building crafts and materials, etc., etc.
[* refer to the 2013 UNESCO Hangzhou Declaration]
In Sustainable Design … there are NO Universal Solutions !
Design Objectives:
To protect society, the best interests of the client/client organization and building user health and safety, and to maintain functionality under the dynamic, complex conditions of fire … Project-Specific Fire Engineering Design Objectives shall cover the following spectrum of issues …
Protection of the Health and Safety of All Building Users … including people with activity limitations (2001 WHO ICF), visitors to the building who will be unfamiliar with its layout, and contractors or product/service suppliers temporarily engaged in work or business transactions on site ;
Protection of Property from Loss or Damage … including the building, its contents, and adjoining or adjacent properties ;
Safety of Firefighters, Rescue Teams and Other Emergency Response Personnel ;
Ease and Reasonable Cost of ‘Effective’ Reconstruction, Refurbishment or Repair Works after a Fire ;
Sustainability of the Human Environment – including the fitness for intended use and life cycle costing of fire engineering related products, systems, etc … fixed, installed or otherwise incorporated in the building ;
Protection of the Natural Environment from Harm, i.e. adverse impacts.
.
More Specifically … with Regard to Resilient Building Performance during a Fire Incident and the ‘Cooling Phase’ after Fire Extinguishment:
1. The Building shall be designed to comply with the Recommendations in the 2005 & 2008 NIST(USA) Final Reports on the World Trade Center(WTC) 1, 2 & 7 Building Collapses.
In one major respect, the 2005 NIST Report is flawed, i.e. its treatment of ‘disability and building users with activity limitations is entirely inadequate. The Building shall, therefore, be designed to comply with International Standard ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’, which was published in December 2011.
2. The Building shall remain Serviceable, not just Structurally Stable(!) … until all buildings users (including those users with activity limitations waiting in ‘areas of rescue assistance’) have been evacuated/rescued to an accessible ‘place of safety’ which is remote from the building, and have been identified … and all firefighters, rescue teams and other emergency response personnel have been removed/rescued from the building and its vicinity.
The Building shall be designed to resist Fire-Induced Progressive Damage and Disproportionate Damage. These requirements shall apply to all building types, of any height.
Under no reasonably foreseeable circumstances shall the Building be permitted to collapse !
3. The Building shall be designed to comfortably accommodate and resist a Maximum Credible Fire Scenario and a Maximum Credible User Scenario.
.
Concerted International Research is Needed …
To creatively resolve the direct conflict which exists between Sustainable Building Design Strategies and Traditional/Conventional Fire Engineering.
An example … for cooling, heating and/or ventilation purposes in a sustainable building, it is necessary to take advantage of natural patterns of uninterrupted air movement in that building. On the other hand, fire consultants in private practice, and fire prevention officers in authorities having jurisdiction, will demand that building spaces be strictly compartmented in order to limit the spread of fire and smoke … thereby dramatically interfering with those natural patterns of air movement. The result is that the sustainability performance of the building is seriously compromised.
If, however, adequate independent technical control is absent on the site of a sustainable building … it is the fire safety and protection which will be seriously compromised !
To effectively deal with the fire safety problems (fatal, in the case of firefighters) which result from the installation of Innovative Building/Energy/EICT Systems and Products in Sustainable Buildings.
.
These are appropriate tasks for a new CIB W14 Research Working Group VI: ‘Sustainable Fire Engineering Design & Construction’ !
2013-09-05: A few days ago, I was travelling on a motorway in Ireland … the scenery was luscious, and daylight and weather conditions were good … when I noticed that the visibility and marking of Emergency Response and Public Service Vehicles varied considerably. The rear of one vehicle, in particular, had highly visible markings … but it was pulling a high trailer, without any markings … and, of course, the vehicle itself and its bright luminescent markings were almost obscured.
What would happen at night, in heavy rain … if any of these vehicles had to stop on a road without any public lighting … as they responded to a traffic accident … or because they were part of a Garda/police checkpoint ? Serious danger for the responders and other road users is the obvious answer !
Then, more recently, while walking around Howth Harbour, in Dublin … I spotted this Irish Coast Guard Vehicle … which made me feel more optimistic …

Both of these documents must be carefully adapted by the reader to suit a European context … as the following List of Recommendations from USFA Report FA-330 will clearly indicate …
To help decrease vehicle-related injuries and fatalities of emergency responders if implemented at the appropriate levels:
1. Develop a comprehensive database that tracks accidents involving emergency vehicles and any resulting injuries and/or deaths to both emergency responders and civilians.
2.Limit speeds to a level that is safe for the vehicle being driven and the road conditions on which it is being operated.
3. Adopt a zero-tolerance alcohol (and drugs) policy and enforce an 8-hour time difference between alcohol consumption and the commencement of work.
4.Equip all emergency vehicles with appropriate traffic control and safety equipment.
5. Ensure all traffic-channelizing devices meet applicable standards.
6. Ensure flaggers, if used, are properly trained and meet Manual of Uniform Traffic Control Devices for Streets and Highways (MUTCD) qualifications.
7. Require members to wear highly reflective American National Standards Institute (ANSI)/International Safety Equipment Association (ISEA) 107 Class II, Class III, or ANSI/ISEA 207 compliant public safety vests whenever they operate in a roadway.
8.Mark the emergency vehicle perimeter with retro-reflective striping or markings.
9.Extinguish forward facing emergency vehicle lighting when parked on the roadway, especially on divided roadways.
10. Fire departments should consider the implementation of traffic safety response units.
11. Position the initial-arriving emergency vehicle in a blocking position to oncoming traffic.
12. Establish an adequately sized work zone.
13. Develop a formalized Traffic Incident Management (TIM) information sharing method between public safety and transportation agencies.
14.Manage major traffic incidents using the National Incident Management System (NIMS) Incident Command System (ICS).
15. Consider the use of Unified Command (UC) to manage traffic incidents involving multiple jurisdictions or disciplines.
16.Incorporate transportation departments into ICS when appropriate.
17. Ensure adequate training on roadway hazards and safety procedures for responders.
2013-07-19: Once upon a time, back in 1979, when I was flying to Sydney, Australia … one of the scheduled stops on the route was Bahrain and the New International Airport Terminal there. In spite of the flashy and expensive building, I noticed how obsolete looking (and functioning) were the fittings in the toilet area. Could it possibly be, I wondered, that the Arab Gulf Region was being supplied with shoddy, second rate construction products from you-know-where ??
Fast forward to a few years ago … in Riyadh, Saudi Arabia … and I encountered one building – the same building – where one half had a 110 Volt electrical supply, and the other half had a 220 Volt supply. Amazing !?! Two different consultants, or contractors, or whatever … one from North America, and the other from Europe … with the Saudis in the middle, having to tolerate this nonsense !!

DOHA City Fire – Monday, 28 May 2012 …
I distinctly remember that some Irish people who had actually witnessed the Fatal Fire Incident at the ‘Villaggio’ Shopping Mall (www.villaggioqatar.com), in Doha (capital city of Qatar) … were afterwards talking to Mr. Joe Duffy, on the lunchtime ‘Liveline’ Programme (Ireland’s RTE Radio 1 Station).
19 People were killed on that Monday morning in Doha … 13 Children, 4 Teachers, and 2 Firefighters. Many more were injured from inhaling toxic smoke.
According to various news reports … an electrical fire, caused by a light fitting (which was not ‘fit for its intended use’) in a Nike Shop, engulfed a section of the shopping centre … spreading to the Gympanzee Drop-and-Shop Childcare Centre on the first floor.
The staircase leading to the Childcare Centre collapsed … trapping victims inside. One of their fire exits led directly to the seat of the fire, while the other fire exit was locked from the outside.
In addition, the ‘Villaggio’ – a luxury mock-Italian shopping centre (one of the most popular in the country !) where customers could ride around Venetian-style Canals, in Venetian-style Gondolas – was later found to be in breach of legislation because Essential Fire Safety Measures were either inadequate or missing, at the time of the fire: the fire sprinkler system was not working properly; inflammable paint and decorative mouldings were used in the construction; the building did not have effective fire evacuation procedures in place; the building was not equipped with proper fire-fighting equipment; and the fire alarm wasn’t loud enough.

A Qatari Court – Thursday, 20 June 2013 …
The recent outcome from this Qatari Court Case has been nagging at me ever since I saw the news on Al Jazeera (English) … www.aljazeera.com
Only Some of the People having Control / Responsibility were convicted for the Negligence which resulted in the 19 Deaths, and many injuries, at the 2012 ‘Villaggio’ Fatal Fire Incident.
Four people received six-year jail terms, while the fifth received a five-year term. All five are currently out on appeal, and will remain out of custody until the appeals process is completed.
Those convicted include Two Co-Owners of the Childcare Centre, and Members of the Mall’s Management Team. Sheikh Ali Bin Jassim Al Thani, one of the co-owners, is also currently Qatar’s Ambassador to Belgium … while Iman Al-Kuwari, the other co-owner, is the daughter of Qatar’s Culture Minister.
Two other defendants, including the Mall’s Assistant Manager and Head of Security, were cleared of all charges.
.
Other People having Control / Responsibility were also Careless, Incompetent, and Negligent …
2013-06-08: Looking forward to some serious, collaborative and multi-disciplinary discussions on the day … and a barrel of laughs in the process (!!) …
The NUIG ‘blurb’ for the day states … “Considering the importance of aggressive energy-efficiency measures in the Building Sector, together with the requirements for a safe, healthy, comfortable (and accessible) Built Environment … this NUIG Workshop will explore the topic of Integrated Modelling and Performance of the Built Environment.”
.
I was very pleased to receive an invitation to make a Presentation at this prestigious event …
‘Sustainable Fire Engineering Design’ – My Presentation Abstract
Fire Engineering … involves much more than mere compliance with building regulations and codes … whose fire safety objectives are limited, and whose performance requirements are sometimes inadequate and always minimal. More problematically … a fundamental conflict is mushrooming between Safe Sustainable Climate Resilient Building Design and Conventional Fire Consultancy Practice.
However … Sustainable Fire Engineering Design Solutions are:
Reliability-based ;
Person-centred ;
… and above all …
Adapted to Local Context and Heritage (fr: le Patrimoine – see ICOMOS 2011) … geography, climate (incl. change, variability and severity swings), social need, culture, and economy, etc., etc.
This Presentation will discuss very rich collaborative research potential in the following areas …
Creative Fire Engineering Concepts and Building Systems
Fire-Induced Progressive Damage in Buildings
Human Behaviour and Abilities in a Fire Situation
Building Design for Firefighter Safety
BMS – Fire Modelling – BIM
Research Output must be targeted at practical implementation in ‘real’ buildings … with actual user/construction performance carefully (i.e. reliably and precisely) monitored !

POST-EVENT UPDATE: 2013-06-27 …
While it was difficult to keep the Workshop Programme, involving a series of short 10-minute presentation slots, on track … discussions during the day were engaging, energetic and extensive.
I happily look forward to a successful and collaborative outcome from the day … Multi-Disciplinary Teams producing Trans-Disciplinary Research Output … which is geared towards practical implementation in ‘real’ buildings, with actual construction and building user performance carefully (i.e. reliably and precisely) monitored !

However … and especially since the Workshop had been organized by IRUSE (the ‘SE’ standing for ‘Sustainable Engineering’) … it was indeed very strange to have to clarify the following points, among others:
1. The Minimum Life Cycle for a Sustainable Building is 100 Years … not 50 or 60 years !
2.Future Research Collaboration should be targeted at the multi-aspect ‘Sustainability Agenda’. The word ‘green’ (where only environmental aspects of sustainability are considered) should be actively discouraged, if not banned entirely !
3. With regard to Good Indoor Air Quality (IAQ) … two high-level performance indicators which have been developed with the aim of protecting human health, and are both now referenced in International Standard ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’ … are …
– Radon Activity (incl. Rn-222, Rn-220, RnD) in a building should, on average, fall within the range of 10 Bq/m3 to 40 Bq/m3, but should at no time exceed 60 Bq/m3 ;
– Carbon Dioxide (CO2) Concentrations in a building should not significantly exceed average external levels – typically within the range of 300 parts per million (ppm) to 500 ppm – and should at no time exceed 800 ppm.
Concerning the substantive difference in meaning and scope between ‘sustainable’ and ‘green’ … there is, perhaps, no better way to illustrate this difference than to observe the atrocious ‘Accessibility-for-All’ Performance (Accessibility for People with Activity Limitations !) of the critically acclaimed (?!?) and award winning (?!?) New Engineering Building in Galway University … which flaunts its ‘über-green’ credentials …
Can you believe what’s in those photographs ?? More importantly … can you believe what’s not in those photographs ???? In such a recently completed building … “incredible” is the only answer to both questions.
.
Under International Law … lack of accessibility, or inadequate accessibility, to the social, built, virtual and economic environments … IS a denial and infringement of the basic human rights of people with activity limitations. It also limits, needlessly and unnecessarily, the numbers of potential users of those environments … which makes no sense at all.
My strong recommendation to Galway University … is to immediately commission a Competent Accessibility Consultant to give the university campus a thorough going over ! You are failing the campus user population … the local community in Galway … and Irish society generally.
My even stronger recommendation to the Architects for the New Engineering Building … RMJM Architects (Robert Matthew Johnson-Marshall) in Scotland, and Taylor Architects in Ireland … is to always commission a Competent Accessibility Consultant on all of your projects … small, medium and large … because you haven’t a bull’s notion about this important dimension of building performance !!
And remember folks … Accessibility has been clearly specified in the new International Standard ISO 21542 as including … ‘access to buildings, circulation within buildings and their use, egress from buildings in the normal course of events, and evacuation in the event of an emergency’.
2013-05-30: Further to the recent post here, dated 2013-04-02 … and this Page on our Corporate WebSite …
Pausing … and stepping back … to consider conventional architectural practice, how architects are educated, and whether or not the professional institutes are helping, or handicapping, the forward progress of Architecture for a Better, More Sustainable World … I am deeply concerned about the future …
1. Should it be ‘Multi-Disciplinary’ or ‘Trans-Disciplinary’ ?
The word ‘trans-disciplinary’ is confusing to a lot of people … surprisingly, to many at senior levels in construction-related industries, research sectors, and academia … not just in Ireland, but internationally. The more senior the level, it seems the higher are the walls of that proverbial ‘box’. But, let me reassure you, thinking outside the ‘box’ is not confined to people in their early 20’s !!
Looking over just the initial list of Consultant Specialists in a complex architectural project … it is the task of the Architect to transform a widely ‘multi-disciplinary’ input into a coherent ‘trans-disciplinary’ output. These two concepts are very different.
Next Generation Architectural Processes and Procedures are urgently required …

2. EU Climate & Energy Policies – Key Driving Forces for Sustainability !
Recently, the European Commission issued this Green Paper … (which, by the way, has absolutely nothing to say about Climate Change Adaptation !) …

European Commission COM(2013) 169 final – Brussels, 2013-03-27
Click the Link Above to read and/or download PDF File (104 Kb)
.
Concerning this Green Paper … Two Important Points …
(i) Current European Union (EU) Climate and Energy Policies are not just a passing fad … they are here to stay. With certainty, we also know that they will become more and more stringent … and that higher levels of performance will be mandated … not just on paper or a computer printout … but in reality, for example, in buildings which are constructed and actually occupied by ‘real’ building users. Refer also to recent findings, in Europe, about the large and growing discrepancy between car fuel efficiencies claimed after testing in a laboratory, and when later monitored under ‘real’ driving conditions.
(ii) It has now become obvious that the European Commission has lost the plot … big time ! Policies and Actions in closely related fields have been permitted to become fragmented, disjointed, and even counter-productive. Written into the EU treaties is the term ‘sustainable development’ … an intricate, open, dynamic and continuously evolving concept. However, senior levels (both political and bureaucratic) in the different Directorates-General of the European Commission have long ago forgotten, mislaid and/or lost the proper meaning of ‘sustainability’ … and the essential interdependency of its many aspects.
.
… which brings me to the urgent necessity for Next Generation Architectural Design Concepts …

In Europe … the 1990’s and early 2000’s, taken together, was a period of construction experimentation and research. We thought we could afford the resources and the lazy times … to try this, that and the other. Little emphasis was placed on practical implementation in ‘real’ buildings. However, the scale and immediacy of today’s Sustainable Development Challenges in the Built Environment have, within a few short years and much more quickly than expected, become unprecedented.
The Yanks (Gringos) are very strong on marketing … much stronger than Europe … so let’s examine a small model building … and see if its Architectural Design Concept is both coherent and comprehensive …
Mr. Amory Lovins, of the Rocky Mountain Institute in the USA ( www.rmi.org ) … has produced a very snazzy Visitor’s Guide to the sprawling complex that is ‘his home, bioshelter and office’ in Snowmass, Colorado … a Guide intended for wide public circulation.
Concerning this Building … Three Points of Interest(?) …
(i) For a fleeting moment … let us imagine that a percentage – not even all – of the vast populations living in Africa, India and China wanted the same sort of lifestyle, including the house, that Amory Lovins possesses. What would be the resource implications for this planet ??

(ii) In a first construction ‘try’ … separate solar and/or photovoltaic panels fixed in place on a roof … attached to the building, almost as an afterthought … were the norm. Now, however, these building systems are no longer innovative … they must be properly shown to be ‘fit for their intended use’ (to comply with building regulations and codes) … and they should now be fully integrated into the architectural design concept for the building … which is not the case in the photograph above. [ Car manufacturers face a similar design challenge today … how to successfully integrate new technologies, e.g. satellite navigation screens, smartphone docking stations, usb sockets, bluetooth, etc., etc., into the front dashboard.]
Anyway … how reproducible is this model building in urban and suburban contexts … in the USA … or elsewhere in the world ?? How many people would have access to sufficient land outside a building to ‘plant’ one, or a series of photovoltaic panels ? Tracking photovoltaic panels, as shown above ?? And as seen in Italy, with those ridiculous photovoltaic fields (in a post, dated 2011-11-07 ) … good agricultural lands should not be used for this purpose … not now, not ever, never !

(iii) Sustainable Buildings are ‘high-tech’ … and a very large amount and variety of electronic and mechanical equipment is necessary in order to reliably monitor and tightly control their performance … in other words, to operate a building in accordance with its design specification. Again … these services should be fully integrated into the architectural design concept for what is, no longer, just a simple dwelling. Do similar houses without basements, for example, now need a central well-ventilated service room, complete with compact workstation ?

In my opinion … the Architectural Design Concept for this building is not coherent. The overall architectural impression is one of a large sprawling house, on a very large plot of land … with many different ‘environmental/energy’-related appendages, or add-ons. Can you see any coherence ?
It is the task of the Architect to consider all facets of building performance at the earliest stages of design … whether a small building, or a very large complex building … and to integrate those many diverse, but interdependent, facets into a coherent architectural statement … having a conceptual single crystalline shape … while also bearing in mind ‘person-centredness’, ‘flexibility’, ‘adaptability’, ‘accessibility for all’, and a ‘long and useful life cycle’.
[ An aside … closer to home … we are now witnessing the rise of the ‘Passive House Designer’. This person, who is able to use a specific computer software package … no less, and no more … need not necessarily be an architect, or have any architectural education/training. Is it possible to refer to the realized output from this software as ‘architecture’ … or are they merely drab, boring boxes ?? ]

3. Sustainable Buildings, Fire Safety & Fire Engineering ?
In the elaborate Amory Lovins Visitor’s Guide above … there is only one mention of fire hazard in the building … and that is in relation to a Passive Clothes Dryer (Page 40). End of story with regard to the Fire Safety Issues for its Users … and the Fire Engineering Implications arising from a chosen architectural design and chosen construction materials and methods.
When I was referring to a centrally located service room in # 2(iii) above … that room should also be structurally hardened, and fire and smoke ‘separated’ from other spaces in the house. Or … if the service equipment is located in a roof space, there are implications for roof structural reliability in a fire situation, and the fire resistance of the ceiling construction beneath. Or … if the equipment is located in a basement, a simple intermediate timber floor construction overhead is inadequate.
Furthermore … an intelligent fire detection and warning system … and a suitable domestic fire suppression system … are no longer luxuries or optional extras, but essential requirements ! Who would want to lose such a valuable investment ??
And insofar as fire safety issues are not being considered … it seems, at all … in the case of most ‘high-tech’, sustainable buildings … and certainly not in the case of the Lovins House … the Architectural Design Concepts for these buildings ‘suffer’ from a gaping hole … an enormous void … they are incomplete and, therefore, entirely inadequate.
Fire Engineering involves much, much more than mere compliance with building regulations and codes … whose fire safety objectives are limited, and whose performance requirements are sometimes inadequate and always minimal.
.
Unfortunately … there is a fundamental conflict between Sustainable Building Design Strategies and the current state-of-the-art in Fire Engineering Design. As an example … for cooling, heating and/or ventilation purposes in a sustainable building, it is necessary to take advantage of natural patterns of air movement in that building. On the other hand, fire consultants in private practice, and fire prevention officers in Authorities Having Jurisdiction (AHJ’s), will demand that building spaces be strictly compartmented in order to limit the spread of fire and smoke … thereby dramatically interfering with those natural patterns of air movement.
In everyday practice, there is a vast chasm in understanding and communication between these two very different design disciplines. As a result, serious compromises are being enforced on Sustainability Performance. If, on the other hand, adequate independent technical control is absent on the site of a Sustainable Building … it is the fire safety and protection which is being seriously compromised.
A range of critical fire safety issues (fatal, in the case of firefighters) are also arising from the Innovative Building Products and Systems being installed in Sustainable Buildings.
And because the emphasis is on pre-construction design ‘intent’ rather than the ‘real’ performance of the completed and occupied building … all of these problems are being conveniently sidestepped or ignored … and they remain hidden from everybody’s view.
.
Sustainable Fire Engineering Design, on the other hand, is the creative response to Sustainable Design … and the powerful drivers of Climate Change Adaptation, and Energy Conservation/Efficiency in Buildings.
Sustainable Fire Engineering Design Solutions are …
Adapted to Local Conditions … Geography, Climate (change, variability and severity swings), Social Need, Culture, and Economy, etc., etc ;
‘Reliability-Based’ … the design process is based on competence, practical experience, and an examination of ‘real’ extreme events, e.g. 2001 WTC 9-11 & 2008 Mumbai Attacks, and 2011 Fukushima Nuclear Incident … rather than on theory alone ;
‘Person-Centred’ … ‘real’ people are placed at the centre of creative endeavours and proper consideration is given to their responsible needs … and their health, safety and welfare … and security … in the Human Environment.
Sustainability … continues to fundamentally transform our Fire Engineering, Architectural and Consultancy Practice at Sustainable Design International Ltd (SDI) !
2013-05-22: Whatever Service Providers claim … every day, we experience mobile/cell phone reception variability, drop-off and failure in buildings … whether we are fully conscious of it or not. It’s inconvenient, but all we have to do is change location, even slightly … and ‘re-dial’. However, if we are travelling on a train or bus, and it enters a tunnel … the problem can be annoying, as the situation is beyond our control !
On the other hand, however … not too far from where I live, there is an art house cinema with underground screens on different levels. In this particular case, mobile/cell phone reception failure can be a positive joy – it will not be necessary to listen to someone else’s loud conversations during the film !
BUT … emergency first responders use radio frequency-based communication systems during the normal course of their work … and in the current built environment, these systems can also be unreliable. Improved climate resilience in our future building stock will make matters worse. So, it makes a lot of sense to take this issue seriously now !
Fire Departments equip their firefighters with a Radio Frequency-Based Personal Alert Safety System (PASS) … also known as an Automatic Distress Signal Unit (ADSU) … which sends out a signal to a fire incident base / control centre / command post when the firefighter is motionless or in distress, with a clear indication of his/her location … or, if necessary, a general warning can be sent from the fire incident base / control centre / command post to all firefighters to evacuate a building immediately … for example, if extensive structural collapse is imminent.
Recently, the National Institute of Science & Technology (USA) issued Technical Note 1792. I have just a few short comments to make before jumping into the document …
1. The Empire State Building and a Subway Station in New York City are both iconic building types … and unusual, in the context of the USA generally … but not so in Europe, with our long tradition for ‘hard/heavy’ construction. Challenging environments for radio frequency-based communication systems are encountered in our basement / underground building types, and low-rise complex building types … never mind high-rise and tall buildings.
2. Outside buildings, adequate external access routes for Firefighting Vehicles are mandated in building codes and standards … and Firefighter Lifts are provided inside buildings, etc., etc., etc. Facilitating reliable radio frequency-based emergency communications should become a normal part of thinking about … and designing for … Safe Firefighter Access. And … before new buildings are occupied, it should become routine to carry out an emergency communications check, as part of a wider collaborative effort between Building Management Teams and Local Fire Services.
3. This NIST Technical Note is further evidence … as if any more evidence were needed … that it is a continuing and difficult process to fully implement the 2005 & 2008 NIST WTC 9-11 Recommendations. To date, the easier low hanging fruit (system and procedural inadequacies !) have been tackled, which may be presented and/or described as substantive changes in building codes and standards … mere window dressing … tokenism, at its worst ! However, as discussed here before many times, some European countries continue to completely ignore these important NIST Recommendations.

March 2013 – NIST Technical Note 1792: ‘Performance Analysis of RF-Based Electronic Safety Equipment in a Subway Station and the Empire State Building’.
Radio Frequency (RF) PASS Tests were performed in a New York Subway Station and the Empire State Building because these types of structures provide challenging RF propagation-channel environments. In the Subway, the RF PASS systems were limited in their ability to communicate beyond the initial entrance level. Without the use of repeaters, most of the systems could communicate only a short distance beyond the bottom of the stairwell that connected the token booth corridor to the street. Two systems used repeaters to extend the coverage area. When a repeater was located at the base of the stairwell leading up to the street, those two systems were able to communicate the RF PASS alarms between the street level and the first passenger platform. However, with only a single repeater, neither of the two repeater systems was able to communicate between the external receive site and the second passenger level. This suggests that for structures with sizable subterranean sections, a repeater system will likely be required to reach an external incident command post. If the structure has multiple subterranean levels of increasing depth, a multiple-hop relay system will likely be necessary to ensure the reliability of the communication channel.

In the path-loss measurements and analysis performed at five frequencies, ranging from 430 MHz to 2405 MHz, there are several important insights. Based on the upper adjacent values in the box-plot statistical representation of the path-loss data from the Empire State Building (see Figure 36), path-loss values of 140 dB to 175 dB are possible for high-rises. For the Subway, the path-loss values exceed 210 dB to 240 dB at the lower two passenger platforms (see Figure 35). The frequency dependence is more pronounced for the Empire State Building results, but less apparent in the Subway data. Thus, while a system may function well at the lower end of the frequency spectrum in the above ground portions of a large building, the subway results demonstrate that subterranean structures can cause path-loss values greater than 200 dB across the 430 to 2400 MHz range.

The testing completed here focused on RF PASS system performance and RF propagation-channel measurements in a high-rise and subway station. While a primary goal of the effort was to look at the correlation between the system performance and path-loss behaviour, a secondary goal was to gather path-loss data in two high-attenuation settings. Thus, parameter values for log-normal distributions that will allow simulation of the measured path-loss conditions are included in this report. The authors hope that the data presented here, along with future sets of data, can be used to develop a complete suite of test methods, not only for RF-based PASS systems, but also for other RF-based electronic safety equipment. The path-loss values obtained here are general and could be used to develop standards for other equipment as the need arises for standards for these systems.
