Ar C.J. Walsh – Registered Architect, Fire Engineer & Independent Technical Controller …… International Expert on Accessibility for All (including Fire Safety) + 'Real' Sustainability Implementation !
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’ !
2014-04-13:Further to the Post, dated 2013-01-13 …
There are many essential qualities and features belonging to and representative of a Sustainable Human Environment (including the Social, Built, Virtual and Economic Environments).As discussed here many times before … Accessibility-for-All is one fundamental attribute, under Social and Legal Aspects of Sustainable Human and Social Development.
Another fundamental attribute … Urban Resilience … is now moving centre stage in the world of International Construction Research & Practice.WHEN, not if … this concept is fully elaborated and understood, it will have a profound impact on All Tasks, Activities and Types of Performance in the Human Environment … under All Aspects of Sustainable Human and Social Development.
After working for many years on Climate Change, particularly Adaptation … it was quite natural for me to encounter the concept of Resilience.But the aim of a newly established Core Task Group within CIB (International Council for Research & Innovation in Building & Construction) is to widen out this concept to also include Severe Natural Events (e.g. earthquakes, typhoons, tsunamis), ComplexHumanitarian Emergencies, (e.g. regional famines, mass human migrations), Extreme Man-Made Events (e.g. 2001 WTC 9-11 Attack, 2008 Mumbai ‘Hive’ Attacks), and Hybrid Disasters (e.g. 2011 Fukushima Nuclear Incident) … to set down Resilience Benchmarks … and to produce Resilience Performance Indicators. An imposing challenge !
AND … as Urbanization is proceeding at such a rapid pace in the BRICS Countries (Brazil, Russia, India, China & South Africa) and throughout the rest of the Southern Hemisphere … ‘practical’ and ‘easily assimilated’ trans-disciplinary output from this CIB Task Group is urgently required.In other words, the work of the Task Group must not be permitted to become an exercise in long drawn out pure academic research … the clear focus must be on ‘real’ implementation … As Soon As Is Practicable !!

SUSTAINABLE DESIGN
The ethical design response, in resilient built and/or wrought form, to the concept of Sustainable Human & Social Development.
SUSTAINABLE HUMAN & SOCIAL DEVELOPMENT
Development which meets the responsible needs, i.e. the human and social rights*, of this generation – without stealing the life and living resources from the next seven future generations.
*As defined in the 1948 Universal Declaration of Human Rights … and augmented by UN OHCHR Letter, dated 6 June 2013, on the Post-2015 Development Agenda.
.
The CITY (as Region)
A geographical region, with open and flexible boundaries, consisting of:
(b)A large resident population of more than 500,000 people (social environment) ;
(c)A supporting hinterland of lands, waters and other natural resources (cultivated landscape) ;
together functioning as …
(i)a complex living system (analogous to, yet different from, other living systems such as ecosystems and organisms) ;and
(ii)a synergetic community capable of providing a high level of individual welfare, and social wellbeing for all of its inhabitants.
.
SOCIAL WELLBEING
A general condition – in a community, society or culture – of health, happiness, creativity, responsible fulfilment, and sustainable development.
INDIVIDUAL WELFARE
A person’s general feeling of health, happiness and fulfilment.
HUMAN HEALTH
A state of complete physical, mental and social wellbeing, and not merely the absence of disease or infirmity.[World Health Organization]
.
SOCIAL ENVIRONMENT
The complex network of real and virtual human interaction – at a communal or larger group level – which operates for reasons of tradition, culture, business, pleasure, information exchange, institutional organization, legal procedure, governance, human betterment, social progress and spiritual enlightenment, etc.
The social environment shapes, binds together, and directs the future development of the built and virtual environments.
BUILT ENVIRONMENT
Anywhere there is, or has been, a man-made or wrought (worked) intervention by humans in the natural environment, e.g. cities, towns, villages, rural settlements, service utilities, transport systems, roads, bridges, tunnels, and cultivated lands, lakes, rivers, coasts, seas, etc … including the virtual environment.
VIRTUAL ENVIRONMENT
A designed environment, electronically generated from within the built environment, which may have the appearance, form, functionality and impact – to the person perceiving and actually experiencing it – of a real, imagined and/or utopian world.
The virtual and built environments continue to merge into a new augmented reality.
ECONOMIC ENVIRONMENT
The intricate web of real and virtual human commercial activity – operating at micro and macro-economic levels – which facilitates, supports, but sometimes hampers or disrupts, human interaction in the social environment.
2013-09-10: Recently, much ado has been made in the technical press about a New Multi-Storey Office Block in Vienna which has achieved the German ‘Passivhaus’ (Passive House) Standard …
Is There A Problem ?? Yes !!
1. It takes approximately 3 Years of Building Occupation, by ‘real’ people, before the actual performance of a building can be properly monitored and reliably shown. The building is still ‘drying out’ for the first year. It takes at least one to two years of running the complex technologies and systems in today’s buildings … training people how to operate them efficiently and effectively … and fine-tuning and de-bugging as you go along … before everything begins to work together, as originally intended during the building design stage. Then, if all goes well … in the third year of occupation, the careful (i.e. accurate and reliable) monitoring of ‘real’ building performance, by means of portable measuring devices and devices installed within the construction, can commence.
So … what exactly has achieved the German ‘Passivhaus’ (Passive House) Standard … the design intent for the building, or the building’s ‘real’ performance ???
.
2. Much more fundamentally … achieving this Standard is a good starting point … but in a new building project … It Is Not Enough !
A. Energy Conservation and Efficiency Burden Sharing by Different Building Types
Separate strategies are required to greatly improve the energy performance of:
existing buildings … onto which many energy efficiency measures can be successfully grafted, but it will be difficult work and will certainly not be cheap ;
buildings of historical, architectural or cultural importance … the integrity of which must be protected ; and
new buildings and facilities … which must therefore carry the major burden.
.
B. Paradigm for New Buildings – A ‘Positive Energy’ Return + Assured Building User Comfort
Primary Energy Consumption should be less than or equal to 15 kWh/m2/yr.
And …
Renewable Energy and Heating Systems should contribute a reliable quantity of energy, per year, which covers the following:
i) the Building’s/Facility’s Primary Energy Consumption ;
ii) an Energy Efficiency Degradation Factor which takes account of the degradation in energy efficiency …
(a) normally expected during the life cycle of renewable energy and heating systems installed in the building. The rate of degradation will depend on the quality of maintenance and servicing ; and
(b) caused by wasteful patterns of building management and/or use ;
iii) the energy consumed by Private Transport associated with the building or facility ;
iv) an Energy Return to an Intelligent District, Local or Regional Grid exceeding, by a multiple of 3 (three), the total energy consumed by the Building/Facility (including its Energy Efficiency Degradation Factor) and any associated Private Transport.
.
Notes:
Primary Energy includes the energy required to generate, transmit and distribute electricity, as well as energy directly consumed on site.
User Thermal Comfort = Air Temperature + Mean Radiant Temperature + Air Humidity + Air Velocity, i.e. draughts (ISO 7730).
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.
‘Person-Centredness’ is a core value of Sustainable Human & Social Development … an essential principle in Sustainable Design … an indispensable support framework for Sustainability-related Policy and Decision-making … and an invaluable indicator when monitoring Sustainability Implementation.
.
Why so because ?
It is the mid-1990’s … in the centre of Dublin City.
Imagine, if you will, a very large historical building having a civic, justice-related function … and also an enormous Energy Bill. As described in a much earlier post, dated 2009-02-20, and the series of posts which followed on the subject of Building Energy Rating (BER) … we found that the most effective and practical remedy for this gaping and continuously haemorrhaging ‘energy’ wound was to approach the problem though the building’s users, their perception of thermal comfort, and International Standard ISO 7730.
The ‘real’ reduction in energy consumption, the ‘real’ increase in the building’s energy efficiency, and the ‘real’ improvements in building user / employee comfort and morale … were astounding !
.
At a 1999 Strasbourg Conference in France … I delivered the following Paper …
These are interesting times; the benefits of modern technology have bypassed and long overtaken the stirring thoughts, visions and catch cries of Architects at the beginning of the 20th Century. However, at this time in Europe, we must now ask ourselves some difficult questions …
“What should be the Design Agenda for the ‘Built Environment’ in the new millennium ?”
“Do we actually understand the ‘real’ needs and desires of ‘real’ people in an inclusive society ?”
It is Sustainable Design – the art and science of the design, supervision of related construction/de-construction, and maintenance of sustainability in the Built Environment – which is currently generating a quantum leap in the forward evolution of a more coherent design philosophy.
Principle 1 of the 1992 Rio Declaration on Environment and Development states …
‘Human beings are at the centre of concerns for sustainable development. They are entitled to a healthy and productive life in harmony with nature.’
Deeply embedded, therefore, within this philosophy is the concept of ‘person-centredness’, i.e. that core design value which places real people at the centre of creative concerns, and gives due consideration to their health, safety, and welfare in the Built Environment – it includes such specific performance criteria as: a sensory rich and accessible (mobility, usability, communications and information) environment; fire safety; thermal comfort; air, light and visual quality; protection from ionizing / electromagnetic radiation; nuisance noise abatement; etc. An important ‘person-centred’ design aid is the questionnaire survey, which is not only a very valuable source of information, but formalizes meaningful consultation between practitioners and end users.
SDI’s Guideline Framework on achieving equality of opportunity and social inclusion, which is based on a strategy produced by Directorate-General V of the European Commission, shows how further essential elements of ‘social wellbeing’ also relate to person-centredness; these include partnership between all sectors of society, consensus, transparency and openness.
This paper explores the rational and legal basis for person-centredness of the Built Environment in Europe. Fieldwork incorporating this innovative approach is also examined. Finally, a body of principles – a European Charter – is outlined which aims to ensure that new construction works, and renovated existing buildings, perform reliably, are adaptable, accessible and responsive, ‘intelligently green’ (French: intelli-verdure), cost-effective and inherently sustainable.

CLIMATE CHANGE ADAPTATION & MITIGATION POLICIES
AND BEFORE developing Climate Change Policies which will have such dramatic impacts on human populations, and their lifestyles, around the globe … perhaps those policies would be more effective, in the ‘real’ world and in the long-term … if we looked at the problem through the ‘eyes’ of people !
It will be worth taking a look at an interesting background paper produced by the World Bank in 2009 … whether you agree or disagree with the following statements …
“A lack of citizen understanding regarding the basics of climate science is an almost universal finding worldwide even though knowledge has increased over time. Especially notable is confusion between the causes of climate change and ozone depletion, and confusion between weather and climate.”
“North Americans know far less about climate change than their counterparts in the developed world.”
“Accurate and complete understanding of information is not a prerequisite for concern.”
“Concern is widespread around the world, but it may also be inversely correlated with the wealth and carbon footprint of a nation, or the socio-economic ‘class’ within a nation.”
“In some studies, more informed respondents reported less concern or sense of responsibility towards climate change.”
“People stop paying attention to global climate change when they realize that there is no easy solution for it. Many people judge as serious only those problems for which they think action can be taken.”

World Bank Working Paper 4940 (2009) – ABSTRACT …
Climate scientists have identified global warming as the most important environmental issue of our time, but it has taken over 20 years for the problem to penetrate the public discourse in even the most superficial manner. While some nations have done better than others, no nation has adequately reduced emissions and no nation has a base of public citizens that are sufficiently socially and politically engaged in response to climate change. This paper summarizes international and national differences in levels of knowledge and concern regarding climate change, and the existing explanations for the worldwide failure of public response to climate change, drawing from psychology, social psychology and sociology. On the whole, the widely presumed links between public access to information on climate change and levels of concern and action are not supported. The paper’s key findings emphasize the presence of negative emotions in conjunction with global warming (fear, guilt, and helplessness), and the process of emotion management and cultural norms in the construction of a social reality in which climate change is held at arms length. Barriers in responding to climate change are placed into three broad categories: 1) psychological and conceptual; 2) social and cultural; and 3) structural (political economy). The author provides policy considerations and summarizes the policy implications of both psychological and conceptual barriers, and social and cultural barriers. An annotated bibliography is included.
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

.
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 ??
Click to enlarge.
(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 !
Photograph taken by Judy Hill Lovins. Click to enlarge.
(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 ?
Photograph taken by Judy Hill Lovins. Click to enlarge.
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.
NIST TN 1792 – Figure 16: ‘Subway + System 4 Performance’. Click to enlarge.
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.
NIST TN 1792 – Figure 21: ‘Tall Building + System 4 Performance’. Click to enlarge.
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.

Indian NBC, Proposed Part 11 on ‘Sustainability’ – December 2012 Consultation
.
Extract From Foreword (Page 7):
‘ Developed nations’ approach to sustainability generally concentrates on energy conservation through high technology innovations, and use of products, materials and designs with lower embodied energy. Their green ratings are based on intent, which implies expert inputs and simulation. The Indian construction industry will do better using our traditional wisdom and practices, building in harmony with nature through regional common knowledge, consuming as little as necessary, applying low cost technology innovations, using recycled materials, and recognizing performance (not intent) through easily measurable parameters wherever feasible.’
How Right They Are About Prioritizing ‘Real’ Performance !!
.
And Just Before That Extract Above:
‘ The authentic (my insert !) Indian way of life is aparigraha (minimum possessions), conservation (minimum consumption), and recycling (minimum waste). These three attributes are the guiding principles for sustainable buildings as well. With these attributes and its rich heritage, India can make a substantial contribution in this field and eventually lead the world on the path of sustainability.’
An Overly Ambitious Target ? Perhaps Not.
.
SDI Supporting India’s National Sustainable Buildings Strategy …
We very much welcome this opportunity to make a Submission on India’s Draft Amendment No.1 to the 2005 National Building Code (SP 7:2005) concerning the Proposed Inclusion of a New Part 11 ‘Approach to Sustainability’.
This IS an important development for India … and it DOES mark a substantial contribution to this field, at international level. We wish that other countries would follow your example … particularly China, the other mushrooming economies in South-East Asia, and the Arab Gulf States.
You may not be aware that Sustainable Design International (SDI) has been specializing in the theory and implementation of a Sustainable Human Environment (social, built, virtual, and economic) since the mid-1990’s.
And, for example … in September 2007, we were invited to make a series of Keynote Presentations to 20 Senior National Decision-Makers, from both the public and private sectors, at a 2-Day Workshop which was organized for us in Lisboa, Portugal. If invited, we would be delighted to repeat this valuable exercise in Dilli, Bengaluru, and other suitable venues in India.
.
IF India is to lead the world on this particular track, i.e. Sustainable Buildings, a coherent philosophy must be outlined in the Proposed New Part 11 of the National Building Code, and a clear direction must also be given there to decision-makers, e.g. clients/client organizations, and designers.
Certain essential content must be included in Part 11. With regard to an improved layout of Part 11, please review the attached SDI Document: ‘SEED Building Life Cycle’ (PDF File, 55 Kb) .
.
Because you have prioritized ‘real’ building performance over pre-construction design ‘intent’, it is appropriate to begin our comments here …
1. Sustainability Performance Indicators
In order to prioritize ‘real’ performance, the monitoring of actual sustainability performance in completed and occupied buildings must be comprehensive, accurate and reliable. Indicators of sustainability performance must, therefore, be included in all sections of the Proposed New Part 11.
Sustainability Performance Indicators provide important signposts for decision-making and design in many ways. They can translate physical and social science knowledge into manageable units of information which facilitate the decision-making and design processes. They can help to measure and calibrate progress towards sustainable development goals, and sectoral sustainability targets. They can provide an early warning to prevent economic, social and environmental damage and harm. They are also important tools to communicate ideas, thoughts and values because, as statisticians say: “We measure what we value, and value what we measure”.
Performance Indicators may be both quantitative and qualitative … but must cover all stages of the building process, i.e. project feasibility and performance specification, spatial planning, design, construction, management, operation, maintenance and servicing, de-construction, disposal, final site clean-up and sustainable repair.
While many, though not all, types of building performance can be successfully monitored using lightweight portable equipment … a certain number of monitoring devices must also be permanently installed in the building during construction. A facility to reliably feed the output from these devices back to data collection points, on site and remote, must also be incorporated in the Building’s Intelligent Management System.
Management and collation of sustainability performance data must be reliable. Uncertainty is always present. Therefore, Statements of Uncertainty should always be attached to ‘reliable’ data.
Safety Factors should always be included when targeting critical ‘health and safety’ related types of performance.
Sustainability Performance Indicators must be directly comparable across different Global Regions … within Asia, across different countries … and within India, across different States. A Balanced, Harmonized Core Set of Indian Performance Indicators should be quickly developed. A Balanced ‘Local’ Set of Performance Indicators will always be necessary.
People tasked with monitoring sustainable building performance must be competent … and independent, i.e. be unconnected to client, design and construction organizations.
Specifically in relation to Energy Performance, the targets to be achieved in new buildings must be far more ambitious. Please review the attached SDI Document: ‘SEED Positive Energy Buildings’ (PDF File, 29 Kb) .

2. Properly Defining ‘Sustainable Development’
As currently drafted … Definition 2.26 Sustainable Development, on Page 13 of the Proposed New Part 11, is not only ambiguous, it is inadequate for India’s needs … and it is barely the first half of the full, correct definition …
Sustainable Development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs. It contains within it two key concepts:
the concept of ‘needs’, in particular the essential needs of the world’s poor, to which overriding priority should be given ; and
the idea of limitations imposed by the state of technology and social organization on the environment’s ability to meet present and future needs.
[ Please refer to the 1987 Report of the World Commission on Environment & Development (WCED): ‘Our Common Future’ – Chapter 2, Paragraph 1.]
This original definition in the 1987 WCED Report IS appropriate for India … and it must become the core definition at the heart of India’s National Sustainable Buildings Strategy !
A careful reading of the full definition makes it clear that there are Many Aspects to this intricate, open, dynamic and still evolving concept … the most important of which are: Social, Economic, Environmental, Institutional, Political, and Legal.
It is a Fundamental Principle of Sustainability, and one of its Primary Values … that Implementation must be Synchronous, Balanced and Equitable across All Aspects of Sustainability.
The ‘Green Agenda’ merely considers Environmental Aspects of Sustainability … in isolation from all of the other Aspects ! This is a fatal flaw which must be avoided in the Proposed New Part 11 !!
[ I made many references to this issue during the FSAI Conferences in India ! ]
.
3. Sustainability Impact Assessment (SIA) for India !
Rather than Environmental Impact Assessment … surely the Proposed New Part 11: ‘Approach to Sustainability’ must now use, explain and discuss Sustainability Impact Assessment instead !?!
Sustainability Impact Assessment (SIA)
A continual evaluation and optimization assessment – informing initial decision-making, or design, and shaping activity/product/service realization, useful life and termination, or final disposal – of the interrelated positive and negative social, economic, environmental, institutional, political and legal impacts on the synchronous, balanced and equitable implementation of Sustainable Human & Social Development.
.
4. A Robust Legal Foundation for ‘Sustainable Human & Social Development’
Paragraph 4 (Chapter 2, 1987 WCED Report) states …
‘ The satisfaction of human needs and aspirations is the major objective of development. The essential needs of vast numbers of people in developing countries – for food, clothing, shelter, jobs – are not being met, and beyond their basic needs these people have legitimate aspirations for an improved quality of life. A world in which poverty and inequity are endemic will always be prone to ecological and other crises. Sustainable development requires meeting the basic needs of all and extending to all the opportunity to satisfy their aspirations for a better life.’
Trying to list the essential needs of people / the basic needs of all is a very difficult task … but it is work which has been on-going, at international level, since just after the Second World War.
The essential needs of people / the basic needs of all … are specified as being Human Rights and Fundamental Freedoms, and are already fully described within the extensive framework of International Legal Rights Instruments.
Which is why, many years ago, SDI developed this definition for Sustainable Human & Social Development … in order:
to give this concept a robust legal foundation ; and
(because of widespread confusion in media, political and academic circles) … to clearly establish that we are talking about sustainable human and social development, and not sustainable economic development, or any other type of development !
Sustainable Human & Social Development
Development which meets the responsible needs, i.e. the Human & Social Rights*, of this generation – without stealing the life and living resources from future generations … especially our children, and their children … and the next five generations of children.
*As defined in the 1948 Universal Declaration of Human Rights.

5. Climate Change Adaptation & Resilient Buildings in India ?
Atmospheric Ozone Depletion and Climate Change are mentioned, here and there, in the Proposed New Part 11. The important implications of these phenomena for Sustainable Building Design in India are not explained … at all. Why not ?
To properly respond to these phenomena, both must be integrated into India’s National Sustainability Strategies & Policies.
At the very least … we strongly recommend that Design Guidance on Climate Resilient Buildings be immediately drafted. This guidance must be appropriate for implementation in each of the different climatic regions of India.
.
6. A Sustainable Indian Built Environment which is Accessible for All !
Barrier Free is mentioned, here and there, in the Proposed New Part 11. This is to be warmly welcomed and congratulated. Under Social Aspects of Sustainable Human & Social Development … this is an essential attribute of a Sustainable Built Environment ! However, no guidance on this subject is given to decision-makers or designers. Why not ?
However, you should be aware that India ratified the United Nations Convention on the Rights of Persons with Disabilities (UN CRPD) on 1 October 2007. For your convenience, I have attached copies of the Convention in English, Hindi and Tamil.
You should also be aware that, in December 2011, the International Standards Organization (ISO) published ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’. In its Introduction, ISO 21542 is directly linked to the U.N. Convention … almost like an umbilical cord. The scope of this Standard currently covers public buildings. As the Accessibility Agenda in the U.N. Convention is very broad … much standardization work remains to be finished at international level.
The correct term … Accessibility for All … has been defined in 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’.
A note at the beginning of the standard also clarifies that Accessibility is an independent activity, i.e. assistance from another person should not be necessary … and that there should be an assurance of individual health, safety and welfare during the course of those (accessibility-related) activities.
In order to fulfil India’s legal obligations as a State Party to the U.N. Convention on the Rights of Persons with Disabilities … adequate Design Guidance on Accessibility must be included in the Proposed New Part 11, supported by ISO 21542.
In addition, the Bureau of Indian Standards (BIS) should immediately adopt ISO 21542 as the Indian National Standard on Accessibility for All … IS / ISO 21542.
[ I made many references to this issue during the FSAI Conferences in India ! ]
.
7. Fire Safety & Protection for All in Sustainable Indian Buildings ?
Yes … there is 1 mention of ‘fire safety’ and 40 other references to ‘fire’ in the Proposed New Part 11 … but no design guidance. Why not ?
You should be aware that there is a fundamental conflict between Sustainable Building Design Strategies and the current state-of-the-art in Fire Engineering Design. As a good 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 engineers 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 Building 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 with the Innovative Building Products and Systems being installed in Sustainable Buildings.
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 ignored, and they remain hidden from everybody’s view.
This must be addressed in the Proposed New Part 11.

As we drive harder and deeper (at least some of us anyway ?) towards a future of Sustainable Human & Social Development … or are forcefully driven by the anthropogenic (man-made) pressures of Resource Shortages (e.g. water – food – energy) and Climate Change, in the case of millions of people living in poverty throughout the world … or are dragged screaming, which I fear will have to be the solution with the privileged classes in every society who are addicted to lavish and wasteful lifestyles and who show absolutely no interest in either Climate Change or Resource Shortages until they rear up and bite them in the ass (!!) … there is a desperate need for a more complex and precise language of Sustainability, which will give shape to the innovative trans-sectoral concepts and trans-disciplinary policy and decision-making support tools required for Tangible/’Real’ Sustainability & Climate Resilience Implementation.
At the time of writing, the Principal Challenge before us is …
Transforming Social Organization … the Ultimate Goal being to arrive quickly at a dynamic and harmonious balance between a Sustainable Human Environment and a flourishing, not just a surviving, Natural Environment … with the Overall Aim of achieving Social Wellbeing for All.

Climate Change did not directly cause Hurricane Sandy, a severe weather event which hit the Caribbean and the East Coast of the USA during October 2012 … but it was a significant contributing factor. Scenes like those in the photograph below will be experienced far more frequently in the future.
This is not Manhattan, in New York City … so, is the development shown below to be removed altogether … or renewed with the necessary and very costly construction of a massive system of flood protection measures ? Not an easy choice. Which choice would be more sustainable ?
However … WHEN, not IF … Average Global Temperatures rise above 1.5 degrees Celsius, many Small Island Developing States (SIDS) will suffer a similar fate … permanently …

In complete contrast … the Type of Development, below, is more Resilient. Furthermore, however, as a normal human reaction to decades of aggressive, but ultimately unsuccessful, political bullying and economic assault by the USA, the Social Fabric of Cuba is very strong … making this a Resilient Human Environment …

What do we mean by Transforming Social Organization ??

Abridged Executive Summary
The term resilience originated in the 1970’s in the field of ecology from the research of C.S.Holling, who defined resilience as ‘a measure of the persistence of systems and of their ability to absorb change and disturbance and still maintain the same relationships between populations or state variables’. In short, resilience is defined as ‘the ability of a system to absorb disturbances and still retain its basic function and structure’, and as ‘the capacity to change in order to maintain the same identity’.
Resilience can best be described by three crucial characteristics: (1) the amount of disturbance a system can absorb and still remain within the same state or domain of attraction; (2) the degree to which the system is capable of self-organization; and (3) the ability to build and increase the capacity for learning and adaptation.
In the need for persistence, we can find a first connection with sustainable development. Sustainable development has the objective of creating and maintaining prosperous social, economic, and ecological systems. Humanity has a need for persistence. And since humanity depends on services of ecosystems for its wealth and security, humanity and ecosystems are deeply linked. As a result, humanity has the imperative of striving for resilientsocio-ecological systems in light of sustainable development.
Resilience thinking is inevitably systems thinking at least as much as sustainable development is. In fact, ‘when considering systems of humans and nature (socio-ecological systems) it is important to consider the system as a whole. The human domain and the biophysical domain are interdependent’. In this framework where resilience is aligned with systems thinking, three concepts are crucial to grasp: (1) humans live and operate in social systems that are inextricably linked with the ecological systems in which they are embedded; (2) socio-ecological systems are complex adaptive systems that do not change in a predictable, linear, incremental fashion; and (3) resilience thinking provides a framework for viewing a socio-ecological system as one system operating over many linked scales of time and space. Its focus is on how the system changes and copes with disturbance.
To fully understand resilience theory, the report focuses therefore on the explanation of a number of crucial concepts: thresholds, the adaptive cycle, panarchy, resilience, adaptability, and transformability.
As shown, humanity and ecosystems are deeply linked. This is also the fundamental reason why to adopt the resilience-thinking framework is a necessity for governance. The resilience perspective shifts policies from those that aspire to control change in systems assumed to be stable, to managing the capacity of socio–ecological systems to cope with, adapt to, and shape change. It is argued that managing for resilience enhances the likelihood of sustaining desirable pathways for development, particularly in changing environments where the future is unpredictable andsurprise is likely.
This exposes the strong need for Sustainable Development Governance to embrace resilience thinking. It is not only about being trans-disciplinary and avoiding partial and one-viewpoint solutions; what is needed to solve today’s problems – and especially those linked to sustainable development – is a new approach that considers humans as a part of Earth’s ecosystems, and one in which policies can more effectively cope with, adapt to, and shape change.
In this scenario, the concept and key characteristics of so-called adaptive governance seem to be a practical means for societies to deal with the complex issues that socio-ecological systems are confronted with. Therefore, adaptive governance is best understood as an approach that unites those environmental and natural resource management approaches that share some or all of the following principles: polycentric and multi-layered institutions, participation and collaboration, self-organization and networks, and learning and innovation. Additionally, four interactive crucial aspects for adaptive governance are suggested: (1) to build knowledge and understanding of resource and ecosystem dynamics; (2) to feed ecological knowledge into adaptive management practices; (3) to support flexible institutions and multilevel governance systems; and,(4) to deal with external disturbances, uncertainty, and surprise. Therefore, nine values toward a resilient world are also suggested: diversity, ecological variability, modularity, acknowledging slow variables, tight feedbacks, social capital, innovation, overlap in governance, and ecosystem services.
Finally, three examples analyse practical instances in terms of resilience: (1) the approach taken by the so-called climate change adaptation discourse; (2) the Kristianstad Water Vattenrike, a wetland in southern Sweden that showed problems with loss of wet meadows, decline of water quality, and a disappearing wildlife habitat; and 3) the Goulburn-Broken Catchment from the State of Victoria (Australia). Some lessons can be drawn from these three cases. From the first case, governance structures have direct implications for the level of flexibility in responding to future change as well as variation in local contexts. Sensitivity to feedbacks relates both to the timing as well as where these feedbacks occur. Therefore, learning is more likely if feedbacks occur soon relative to action, and if those most affected by feedbacks are those responsible for the action. Additionally, the way in which a problem is conceptually framed determines the way in which responses are identified and evaluated and therefore influences the range of response characteristics. Second, the example from Sweden revealed that (a) the imposition of a set of rules to protect an ecosystem from the outside will not ensure the natural qualities of a region will be preserved over time. One size never fits all, and an understanding of local history and culture needs to be integrated into the management if local values are to be looked after; (b) for an organization to meaningfully deal with complexity at many scales, it needs to include representatives from each of these levels in the social network; (c) several organizations need to be prepared to contribute to a shared vision and build consensus and leadership – crucial components in adaptability and transformability. Third, the Goulburn-Broken story demonstrates the critical importance of understanding the underlying variables that drive a socio-ecological system, knowing where thresholds lie along these variables, and knowing how much disturbance it will take to push the system across these thresholds.
