2017-10-10: After the Grenfell Tower Fire Tragedy in London, on 14 June 2017, the integrity of the English Regulatory and Technical/Building Control Systems is now so compromised that a complete Systems Transformation is immediately required ! Closer to home, here in Ireland … what nobody is daring to say, even our tame media, is that Our Regulatory System is based very closely on the English System. And Our Technical/Building Control System is purposefully under-resourced … so it is weak and ineffective.
Let there be no confusion … Priory Hall and Longboat Quay, both in Dublin, are just the tip of an enormous iceberg …

So where do we start again ?
Reality – Reliability – Redundancy – Resilience !
With regard to Reliable Fire Engineering Related Design, Supply and Construction … this is how we must proceed …
Design of the works is exercised by an independent, appropriately qualified and experienced architect/engineer/fire engineer, with design competence relating to the fire protection of buildings ;
Supply of fire safety related construction products/systems to the works is undertaken by reputable organizations with construction competence, particularly in relation to the fire protection of buildings ;
Installation/fitting of fire safety related construction products/systems is exercised by appropriately qualified and experienced personnel, with construction competence relating to the fire protection of buildings ;
Supervision of the works is exercised by appropriately qualified and experienced personnel from the principal construction organization ;
Regular inspections, by appropriately qualified and experienced personnel familiar with the design, and independent of both the design and construction organizations, are carried out to verify that the works are being executed in accordance with the design.
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.

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 !) …

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 !

(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) !
