2020-09-22: Adopted at the International Fire Conference: SFE 2016 DUBLIN (www.sfe-fire.eu) …
Many years have passed since the 1972 UN Stockholm Declaration on the Human Environment and the 1992 Rio Declaration on Environment and Development. In 2016, Sustainable Development remains an intricate, open, dynamic and continually evolving concept. The guide and driver for frontline practitioners, policy and decision makers must be a personal Code of Ethics … an integrated and inter-related whole which cannot be reduced to fixed rules inviting game playing and ‘trade-offs’. After working with this Code, it may be necessary to expand on and discuss its principles and/or some of the issues raised … not to narrow its focus, but to broaden interpretation.
The realization of a Safe, Inclusive, Resilient & Sustainable Built Environment demands a concerted, collaborative, very creative and widely trans-disciplinary effort at national, local, regional and international levels across the whole planet – Our Common Home. The informed operation of appropriate legislation, administrative procedures, performance monitoring and targeting, and incentives/disincentives, at all of these levels, will facilitate initial progress towards this objective … but not the quantity, quality or speed of progress necessary. Our time is running out !
This Code of Ethics applies … for those who subscribe to its values … to policy and decision makers, and the many different individuals and organizations directly and indirectly involved in the design, engineering, construction, and operation (management and maintenance) of a Safe, Resilient & Sustainable Built Environment for ALL.
The Purpose of this Code of Ethics is to guide the work of competent individuals and organizations in a context where incomplete or inadequate legislation, administrative procedures and incentives/disincentives exist … but, more importantly, where they do not exist at all … and, amid much confusion and obfuscation of the terms, to ensure that implementation is authentically ‘sustainable’, and reliably ‘safe’ and ‘resilient’ for every person in the receiving community, society or culture … before it is too late !
Update 2020-09-01: Although the term ‘Vulnerable People’ remains unaltered, I considered it wise, and very necessary bearing in mind the obvious myopia in the mainstream health, safety and design worlds … clearly demonstrated by the 2017 Grenfell Tower Fire in England, and this current CoronaVirus / CoVID-19 Global Pandemic … to include references to specific social groups …
Vulnerable People: Those people – in a community, society or culture – who are most at risk of being physically, psychologically or sociologically wounded, hurt, damaged, injured, or killed … and include, for example, people with disabilities, young children, people with health conditions, frail older people, women in late pregnancy, refugees, migrants, prisoners, the poor, and homeless.
2020-07-20: So many diverse design disciplines and interested groups are involved in the realization, operation and maintenance of a Safe, Inclusive, Resilient and Sustainable Human Environment (built, social, economic, virtual, and institutional) … that the use of simple, easily assimilated language and precise, harmonized technical terminology must be widely exercised. For the effective application of Building Information Modelling (BIM), this is particularly important.
And concerning Fire Engineering, it is not clear when the practice began, but defining a concept simply in terms of performance in a ‘standard test fire’ is entirely inadequate, and fails to explain the actual meaning of the concept.
This Terminology … a body of particular terms, each explaining and defining a single concept, covering inter-related building requirements, e.g. human health, accessibility and fire safety for all, firefighting, social rights, design, performance monitoring, and facility management … takes account of:
Sustainability Impact Assessment (SIA)
WHO International Classification of Functioning, Disability and Health (ICF)
Universal Declaration of Human Rights (UDHR)
U.N. Convention on the Rights of Persons with Disabilities (CRPD)
Fire Engineering Terms … take account of the ‘realistic’ end condition, i.e. a real fire in a real building which is occupied or used by real people with varying behaviour and abilities in relation to self-protection, independent evacuation to an external place of safety remote from a fire building, and active participation in a building’s Fire Emergency Management Plan.
General Terms … are also included in order to facilitate a better understanding of:
the complexity of human behaviour and perception (visual, auditory, olfactory, gustatory, tactile and proprioceptive) ;
the wide range of health conditions ; and, more specifically
2019-04-05 (2021-07-22): Let us imagine, for a moment, that we are in another dimension … The Twilight Zone …
… and that this is a Positive Energy Building, set in a sprawling, diverse, interconnected and flourishing #Woodland with its ecosystems, flora and fauna … an idealized scene … the Sustainability Idyll …
But … is it … ?? What percentage of the world’s population would ever have the opportunity to live this way ???
And … lurking all around this beautiful scene, is an inherent and growing threat to life, property, and those trees, shrubs, and wildlife … #Wildfires / #Bushfires …
The Aim of Sustainable Fire Engineering (#SFE) is to dramatically reduce direct and indirect fire losses in the Human Environment (including the social, built, economic, virtual, and institutional environments) … to protect the Natural Environment … and, within Buildings, to ensure that there is an effective level of Fire Safety for All Users / Occupants, not just for Some, during the full building life cycle.
[ Human Environment: Anywhere there is, or has been, an intrusion by a human being in the Natural Environment. ]
So … how do we reduce direct and indirect fire losses in the Human Environment … and improve its #Resilience ?
A recent publication provides a good platform – a benchmark – to begin this serious conversation …
December 2018 … the International Union of Forest Research Organizations (#IUFRO), which is based in Vienna, published Occasional Paper No. 32: ‘GLOBAL FIRE CHALLENGES IN A WARMING WORLD – Summary Note of a Global Expert Workshop on Fire and Climate Change’ …
Today, catastrophic wildfires are increasingly common across the globe. Recent disasters have attracted media attention and strengthened the perception of wildfires as ‘bad’ events, a plague worsened by climate disruption that has yet to be eradicated. Although it is true that fire has a destructive potential, the reality of global fire activity depicts a much more complex picture in which fire can be a useful, if not necessary, tool for food security and the preservation of cultural landscapes, as well as a an integral element of many ecosystems and their biodiversity.
Global fire activity is shaped by diverse social, economic, and natural drivers influencing the fire environment. The culminating complexity of these factors defines, in turn, the likelihood of a landscape to burn and the potential positive or negative outcomes for communities and ecosystems that can result from a blaze. Although many regions remain understudied, the effects of ongoing climate disruption associated with other planetary changes are already visible, transforming fire activity in ways that are not well understood but are likely to be dramatic, with potential dire consequences for nature, and society in case of #Adaptation failure.
Based on the limited available statistics, there is a growing trend in the cost of wildfires. In addition to human lives that are lost to flames or smoke, and the billions of euros imputable to firefighting and insurance coverage, the growing interest in costs linked to healthcare, business stability, or the provision of ecosystem services such as drinking-water indicates negative economic consequences impacting countries’ GDP and social stability. Attempts to evaluate the future costs of wildfire disasters point at a worsening situation, yet the list of possible social and economic effects is incomplete and the magnitude of envisaged impacts is conservative.
Notwithstanding the difficulties inherent to global climate modelling, there is a scientific consensus on the future increase in the frequency of fire-conducive weather associated with drier ecosystems, a mix that will eventually result in more frequent and intense fire activity. When combined with an ever-growing world population and unsustainable land uses, the conditions leading to fire disaster will only be intensified. Although fire governance has historically advocated for fire suppression, a ‘NO FIRE’ motto is not an option anymore in the new fire reality. Current policies aiming at total fire suppression have been shown to be detrimental and are therefore outdated. The key to wildfire disaster risk reduction in a changing world now lies in learning to live with fire.
Investments in international co-operation, integrated management, local community involvement, cutting-edge technologies, and long-term data collection are critically needed to ensure the future of fire disaster risk mitigation. Moreover, future land development policies must prioritize the protection and the restoration of natural and cultural landscapes that have been degraded by the inappropriate use of fire or, conversely, by historical fire exclusion; keeping a place for fire in forest resource management and landscape restoration has been shown to be a cost-effective and efficient solution to reduce fire hazard.
Overall, synthesis of globally available scientific evidence revealed the following key issues for Landscape Management and Governance:
Climate Disruption, with longer, hotter, and drier fire seasons, in combination with other environmental changes linked to population growth and unsustainable land-use practices, is contributing to extreme wildfire events that exceed existing fire management capacities. The world is entering a ‘new reality’ that demands new approaches to fire governance.
Fire is an inherent feature of the Earth System and many ecosystems, including their fauna, are dependent on it for their long-term survival; nevertheless, ongoing changes in global fire activity in terms of location, intensity, severity, and frequency will have immense costs for biodiversity, ecosystem services, human well-being and livelihoods, and national economies – to extents that have yet to be evaluated. Investment in social, economic, and environmental monitoring is therefore urgent, especially in under-studied regions.
Integrated fire risk reduction is key to adapting to ongoing changes in global fire risk. Future #Sustainable Fire Risk Mitigation demands integrated region-specific approaches based on a clear understanding of fires in context, population awareness and preparedness, fire surveillance and early-warning systems, adaptive suppression strategies, fire-regime restoration, landscape-scale fuel management, changes to many land use practices, and active restoration of landscapes.
Engagement with local communities, land-owners, businesses and public stakeholders – via multiple tiers of governance – is crucial to restore and maintain landscapes that are biodiverse and functional, respectful of local cultures and identities, economically productive, and above all, fire-resilient.
People have historically achieved sustainable co-existence with flammable ecosystems and have often used fire as a land-management tool, thereby shaping many modern and long-standing landscapes around the world. Traditional fire knowledge is thus key to adapting to local changes in fire activity, using known techniques for the reduction of dangerous fuel loads, prescribed burning and sustainable landscape management practices.
Building adaptive capacity to confront fires must be based on knowledge of the natural and cultural roles of fire, how they have shaped our modern landscapes, and their importance in the long-term functioning of socio-ecological systems. Further developments in land-system science, geospatial technologies, and computer modelling will enhance our understanding of the long-term ecological and socio-economic drivers of fire through the widespread collection and distribution of harmonized fire data at the global level. However, creating and sharing such knowledge requires national and international investments in scientific and operational fire science programmes.
Catastrophic fires are undeniably part of our future. Current scientific estimates are conservative, meaning that changes in fire activity might be worse than anticipated. We have to act now to mitigate catastrophic fires and limit the occurrence of disastrous situations. Given disparities but also similarities in the levels of fire risk around the world, and the capacities to manage it, knowledge and technology transfers through international cooperation will be a paramount factor in learning to live with fire.
This Occasional Paper is the result of a large collaborative effort by fire scientists and practitioners who believe that learning to co-exist with changing fire activity is not only possible but necessary if we, as a global society, are to adapt to climate disruption and keep our natural and cultural landscapes healthy, resilient, and safe for the next generations. The work presented hereafter was developed during, and as follow-up to, the Global Expert Workshop on ‘Fire and Climate Change’ hosted in Vienna, Austria, on 2-4 July 2018. It stresses the diversity and the complexity of the global fire situation, a situation that is evolving, positively or negatively, in unknown proportions due to global environmental changes — with climate disruption being the most acknowledged manifestation.
Conclusion – Learning To Live With Fire
We live on a flammable planet; although not everything is meant to burn, fire cannot be eliminated. Ongoing global climate disruption combined with other planetary changes is leading to more frequent and more extreme fires exposing vulnerable societies, economies, and ecosystems to disaster situations. The recognition of fire activity as a worsening hazard threatening human security is the necessary first step towards international co-operation for the mitigation of disaster risk situations in fire-prone areas.
However, we are not defenceless. Fire scientists in many regions of the world have been developing successful strategies and tools based on cutting-edge technologies for several years. Those are now mature enough to be up-scaled and adapted to other geographic contexts as part of national fire management frameworks. Additionally, integrating existing and future scientific knowledge on climate disruption and changing fire regimes, and systematically collecting long-term data on current and past fire uses will foster better informed decisions, models and enhanced efforts towards Wildfire Disaster Risk Reduction, as well as contribute to the development of Sustainable Anthropocene Fire Regimes.
We hope this paper will be a catalyst for a paradigm shift, so fires are not seen as an enemy to fight but as natural and necessary phenomena, as well as a useful and necessary tool that can often help protect people and nature. It is paramount to revise, fund, and fulfil future management, research, and governance needs if we are, as world citizens, to trigger a societal change that will help us better live with fires.
The information and insights contained in this Occasional Paper connect together to promote the use of several existing solutions to the problem: defining national fire risk reduction frameworks, collecting and analyzing relevant traditional knowledge and biophysical fire data, investing in fire detection and prediction technologies, involving and preparing stakeholders, and improving fire use and landscape management in ways that help control the fuel load and the spread of fire, while limiting GreenHouse Gas (#GHG) emissions and protecting the communities and the landscapes they live in and often depend on.
The Status Quo is no longer an option; it is time to make Integrated Fire Management the rule rather than the exception.
The creative, person-centred and ethical fire engineering response – in resilient built or wrought form, and using smart systems – to the intricate, open, dynamic and continually evolving concept of Sustainable Human & Social Development … the many aspects of which must receive balanced and synchronous consideration.
SFE PRIORITY THEMES
1. Fire Safety for ALL – Not Just for SOME People. Nobody Left Behind !
Do Building Designers and Fire Engineers have any understanding of what it feels like to be left behind in a fire emergency … perhaps to die ?
Do Building Designers and Fire Engineers have any understanding of the ‘real’ people who use their buildings … or their ‘real’ needs ?
2. Firefighter Safety – It’s So Easy to Dramatically Improve Their Safety At A Fire Scene ! A Firefighter’s Protective Clothing and Equipment are not enough !
Conscious awareness of this issue by Building Designers and Fire Engineers is required … and appropriate education/training.
3. Property Protection – A Minor Code Fire Safety Objective, Insofar As It Is Necessary to Protect the Safety of Building Users … Only !
Fire damage and post-fire reconstruction/refurbishment are a huge waste of resources. On the other hand, protection of an organization’s image/brand is important … and business continuity is essential.
Heritage Fire Losses cannot be replaced !
To properly protect Society and the interests of a Client/Client Organization … Building Designers and Fire Engineers are ethically bound to clearly explain the limitations of Code and Standard Fire Safety Objectives to their Client/Client Organization.
4. Environmental Impact – Prevention Is Far, Far Better Than Cure. Instead of resisting, and erecting ‘professional’ barriers … Spatial Planners, Building Designers and Fire Engineers must begin to properly understand this concept … and act ethically to defend and protect the environment !
Environmental Impact: Any effect caused by a given activity on the environment, including human health, safety and welfare, flora, fauna, soil, air, water, and especially representative samples of natural ecosystems, climate, landscape and historical monuments or other physical structures, or the interactions among these factors ; it also includes effects on accessibility, cultural heritage or socio-economic conditions resulting from alterations to those factors.
This Planet – Our Common Home – can no longer suffer the scale and extent of total devastation seen after the 2015 Tianjin (China) Regional Fire Disaster !
5. Building Innovation, People and Their Interaction – Fire Engineers and Firefighters must understand current approaches to more sustainable building design, the ‘real’ people who use the built environment, and the complex interactions between both.
People with Activity Limitations (E) / Personnes à Performances Réduites (F): Those people, of all ages, who are unable to perform, independently and without aid, basic human activities or tasks – because of a health condition or physical/mental/cognitive/psychological impairment of a permanent or temporary nature.
The above Term, in English and French, includes …
people who experience difficulty in walking, with or without a facilitation aid, e.g. stick, crutch, calliper or walking frame ;
wheelchair users ;
the very young (people under 5 years of age), frail older people, and women in the later stages of pregnancy ;
people who are visually and/or hearing impaired ;
people who suffer from arthritis, asthma, or a heart condition … or any partial or complete loss of language related abilities, i.e. aphasia … or who have a cognitive impairment disorder, including dementia, amnesia, brain injury, or delirium ;
people impaired after the use of alcohol, other ‘social’ drugs e.g. cocaine and heroin, and some medicines … or following exposure to environmental pollution and/or other irresponsible human activity, e.g. war or terrorism ;
people who experience a panic attack in a real fire situation or other emergency ;
people, including firefighters, who suffer incapacitation as a result of exposure, during a real fire, to smoke and poisonous/toxic substances and/or elevated temperatures.
6. Sustainable Design & Engineering – Get With The Programme ! The extensive United Nations 2030 Sustainable Development Framework Agenda was overwhelmingly agreed and adopted in 2015.
Sustainability Impact Assessment (SIA): A continual evaluation and optimization process – informing initial decision-making, design, shaping activity/product/service realization, useful life, and termination or final disposal – of the interrelated positive and negative social, environmental, economic, institutional, political and legal impacts on balanced and equitable implementation of Sustainable Human & Social Development.
‘Carrots and Sticks’ can only achieve so much. Spatial Planners, Building Designers and Fire Engineers must – individually and as a group – subscribe to a robust Code of Ethics which is fit for purpose in today’s Human Environment.
New CIB W14: ‘Fire Safety’ Research Working Group VI Reflection Document: ‘Sustainable Fire Engineering Design, Construction & Operation’, which will establish a framework for the future development of Sustainable Fire Engineering.
Preparation of this Document will soon begin, and the following issues will be explored:
Conceptual Framework for Sustainable Fire Engineering (SFE), with a necessary accompanying Generic SFE Terminology ;
Strategy for Future SFE Development ;
Implementation of 2005 & 2008 NIST WTC 9-11 Recommendations ;
Fresh, New SFE Research Agenda ;
Resilient Implementation of SFE Research Agenda.

PRIORITY THEME 1 – FIRE SAFETY FOR ALL (2017)
The Fire Safety Task Group, chaired by CJ Walsh, of ISO Technical Committee 59, Sub-Committee 16, Working Group 1, has already commenced the revision and further development of the fire safety texts in International Standard ISO 21542 (2011): ‘Building Construction – Accessibility & Usability of the Built Environment’.
The main effort, initially, has been focused on developing a coherent Fire Safety for All approach … token consideration, or a post-design graft-on, of the fire safety needs of people with activity limitations do not work, and are unacceptable.
On the day before that, 21 April, in a Press Release issued by the World Meteorological Organization (WMO) …
A prolonged run of record global temperatures and extreme weather, the rapid melting of Arctic ice, and widespread bleaching of ocean coral reefs underline the urgent need to sign and implement the Paris Agreement on Climate Change, according to the World Meteorological Organization (WMO).
WMO Secretary-General Petteri Taalas said that 2016 has so far overshadowed even the record-breaking year of 2015.
“The magnitude of the changes has been a surprise even for veteran climate scientists. The state of the planet is changing before our eyes,” said Mr Taalas.
A little earlier in April 2016 … and within the above international context came this problematic, but not-entirely-unexpected tale from Great Britain … the tip of a foul-smelling iceberg in quite a few countries …
Green Deal & Energy Company Obligation
“Improving household energy efficiency is central to government achieving its aims of providing taxpayers with secure, affordable and sustainable energy. The Department of Energy and Climate Change’s ambitious aim to encourage households to pay for measures looked good on paper, as it would have reduced the financial burden of improvements on all energy consumers. But in practice, its Green Deal design not only failed to deliver any meaningful benefit, it increased suppliers’ costs – and therefore energy bills – in meeting their obligations through the Energy Company Obligation (ECO) Scheme. The Department now needs to be more realistic about consumers’ and suppliers’ motivations when designing schemes in future to ensure it achieves its aims.”
Amyas Morse, Head of the British National Audit Office (NAO), 14 April 2016.
[ And as you read further down … consider how important it must be for future effective climate change policy implementation in all of our countries, particularly those countries with an ‘historical responsibility’ …
that accurate, precise and reliable climate change data and statistics be gathered together and properly managed … and this means, for example, that at European Union Member State level, the national statistics organization must be in control of the process … and at EU level, Eurostat must be in control ;
that implementation be stringently and independently monitored for long-term effectiveness ;
that economists be removed from core decision-making in this area … and the veto they currently exercise over necessary mitigation and adaptation actions be removed. ]
The National Audit Office has today concluded that the Department of Energy and Climate Change’s (DECC) Green Deal has not achieved value for money. The scheme, which cost taxpayers £240 Million including grants to stimulate demand, has not generated additional energy savings. This is because DECC’s design and implementation did not persuade householders that energy efficiency measures are worth paying for.
The NAO Report: Green Deal and Energy Company Obligation also found that DECC’s design of its Energy Company Obligation (ECO) scheme to support the Green Deal added to energy suppliers’ costs of meeting their obligations. This reduced the value for money of ECO, but the Department’s information is not detailed enough to conclude by how much suppliers have met their obligations for saving carbon dioxide (CO2) and reducing bills.
The report finds that while the Department achieved its target to improve 1 Million Homes with the schemes, this is not a direct indicator of progress against the objective of reducing carbon dioxide (CO2) emissions. This is because different types of energy-efficiency measures save different amounts of CO2.
The schemes have saved substantially less CO2 than previous supplier obligations, mainly because of the Department’s initial focus on ‘harder-to-treat’ homes, as its analysis showed that previous schemes had absorbed demand for cheaper measures. The Department expects the measures installed through ECO up to 31 December 2015 to generate 24 Mega Tonnes of carbon dioxide (Mt CO2) savings over their lifetime, only around 30% of what the predecessor schemes achieved over similar timescales.
Demand for Green Deal finance has fallen well below the government’s expectations, with households only funding 1% of the measures installed through the schemes with a Green Deal loan. The schemes have not improved as many solid-walled homes, a key type of ‘harder-to-treat’ homes, as the Department initially planned. As part of changes to ECO in 2014, the Department enabled suppliers to achieve their obligations with cheaper measures, moving away from its focus on harder-to-treat properties. ECO has generated £6.2 Billion of notional lifetime bill savings to 31 December 2015 in homes most likely to be occupied by fuel poor people. Beyond this, the Department cannot measure the impact of the schemes on fuel poverty.
There are significant gaps in the Department’s information on costs, which means it is unable to measure progress towards two of its objectives: to increase the efficiency with which suppliers improve the energy efficiency of ‘harder-to-treat’ houses, and to stimulate private investment. The lack of consistency in the government’s approach during the schemes could increase the long-term costs of improving household energy efficiency.
In the NAO’s accompanying investigation into DECC’s loans to the Green Deal Finance Company, also published today, it found that the Department expects that it will not recover its £25 Million stakeholder loan to the finance company, plus £6 Million of interest that has accrued on it. The Department based its stakeholder loan on forecasts of significant consumer demand for Green Deal loans. But demand for Green Deal finance was lower than the Department forecast from the outset, meaning the finance company could not cover its operating costs. The Department agreed a second loan worth up to £34 Million in October 2014, of which the finance company has drawn down £23.5 Million. The Department still expects to recover this loan in full as it will be repaid before other investors in the finance company.
Is it any wonder that the ‘real’ Greenhouse Gas (GHG) Numbers continue to climb relentlessly ?!?

INTRODUCTION to SFE 2016 DUBLIN
Fire Losses – both direct and indirect – amount to a very significant percentage of GDP in all economies, whether they are rich or poor … and result in enormous environmental damage and social disruption. Fire Engineering, including Fire Prevention and Protection in Buildings, is a major multi-billion Euro/Dollar component of the Construction Industrial Sector – worldwide.
Unfortunately … a fundamental conflict exists between Sustainable Building Design Strategies and the fire safety responses adopted in today’s Conventional Fire Engineering. To take a simple example: for cooling, heating or ventilation purposes in a Sustainable Building, it is necessary to take advantage of natural unobstructed patterns of air movement in that building. On the other hand, fire engineers in private practice and control personnel in Authorities Having Jurisdiction (AHJ’s) will demand that building spaces be tightly compartmented in order to limit the spread of fire and smoke … dramatically interfering with those natural patterns of air movement.
Unusual fire behaviour and a range of difficult fire safety issues (critical, in the case of firefighters) also arise from the Innovative Design Features (for example, ‘green’ roofs, elaborate intelligent façades) and Building Products / Systems (for example, photovoltaic panels) being installed in Sustainable Buildings.
A wide chasm separates the language and understanding of these two very different design disciplines. As a result, the performance of Sustainable Buildings can be seriously compromised. If, on the other hand, adequate independent technical control is absent on site … it is fire safety which is weakened.
And because, in most countries, the emphasis is placed on pre-construction design intent rather than the ‘real’ performance of the completed/occupied building … these problems are ignored and remain hidden … until a serious fire breaks out !
SUSTAINABLE FIRE ENGINEERING’s AIM
The Aim of Sustainable Fire Engineering is to dramatically reduce all direct and indirect fire losses in the Human Environment (including social, built, economic, environmental, virtual, and institutional) … and to protect the Natural Environment.
Towards Zero Preventable Fires in the Built Environment !
In essence … Sustainable Fire Engineering heavily front-loads Fire Prevention and Fire Protection Measures … above and beyond the minimal and very limited fire safety objectives mandated by current legislation.
Adapted to local geography, climate change and variability, social need, economy, and culture ;

2015-01-31: The beginning of this 21st Century is deeply unsettling … history is catching up on us, and old certainties are crumbling before our eyes …
The recent, extremely violent Paris Hive Attacks … which occurred between Wednesday and Friday (7-9 January 2015) … have again shown that co-ordinated attacks on a small number of carefully chosen, low-level targets can be just as effective in causing widespread social and economic disruption in a City as a single attack on a high-level target. Search for our previous detailed discussion, here, on the 2008 Mumbai ‘Hive’ Attacks.
On this tragic occasion, the attacks happened in Europe … not, as before, in far-off India.
Following the 2001 WTC 9-11 Attacks in New York City … the U.S. National Institute of Standards and Technology (NIST), in 2005 and 2008, recommended that these Building Types should be treated as ‘Risk Priorities’ …
• Tall / High-Rise Buildings ;
• Iconic Buildings ;
• Buildings Having a Critical Function ;
• Buildings Having an Innovative Design.
However, a typical medium-rise office building (in Paris) and off-street supermarket do not fall into the above categories … another indication that the NIST Recommendations must soon undergo a thorough international review and updating.
In the real world, the whole urban and sub-urban infrastructure of a City is at risk from Extreme Man-Made Events … one more risk among significant others, i.e. Hybrid Disasters (e.g. 2011 Fukushima Nuclear Incident), Severe Natural Events (e.g. earthquakes, typhoons, tsunamis) and Complex Humanitarian Emergencies (e.g. mass human migrations, regional famines). And with 50% of the world’s population already living in Cities, and substantial urban population growth projected over the coming decades … it is clear that, in the short to medium term, Cities must become much more resilient. Search for our continuing discussion, here, about Sustainable Urban Resilience.
In this context, compliance solely with the minimal and limited fire safety objectives in current national legislation – from whatever source around the world – is so far from being either adequate or acceptable … that it is no longer worth a moment’s consideration.
A Fire Engineering which is ‘fit for purpose’, i.e. is both ethical and professional, in today’s complex and dynamic Human Environment … has an essential and critical part to play in the realization of a Safe, Resilient and Sustainable Built Environment for All !
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 …
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 ]
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 !
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’ !
