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 ??
(ii) In a first construction ‘try’ … separate solar and/or photovoltaic panels fixed in place on a roof … attached to the building, almost as an afterthought … were the norm. Now, however, these building systems are no longer innovative … they must be properly shown to be ‘fit for their intended use’ (to comply with building regulations and codes) … and they should now be fully integrated into the architectural design concept for the building … which is not the case in the photograph above. [ Car manufacturers face a similar design challenge today … how to successfully integrate new technologies, e.g. satellite navigation screens, smartphone docking stations, usb sockets, bluetooth, etc., etc., into the front dashboard.]
Anyway … how reproducible is this model building in urban and suburban contexts … in the USA … or elsewhere in the world ?? How many people would have access to sufficient land outside a building to ‘plant’ one, or a series of photovoltaic panels ? Tracking photovoltaic panels, as shown above ?? And as seen in Italy, with those ridiculous photovoltaic fields (in a post, dated 2011-11-07 ) … good agricultural lands should not be used for this purpose … not now, not ever, never !
(iii) Sustainable Buildings are ‘high-tech’ … and a very large amount and variety of electronic and mechanical equipment is necessary in order to reliably monitor and tightly control their performance … in other words, to operate a building in accordance with its design specification. Again … these services should be fully integrated into the architectural design concept for what is, no longer, just a simple dwelling. Do similar houses without basements, for example, now need a central well-ventilated service room, complete with compact workstation ?
In my opinion … the Architectural Design Concept for this building is not coherent. The overall architectural impression is one of a large sprawling house, on a very large plot of land … with many different ‘environmental/energy’-related appendages, or add-ons. Can you see any coherence ?
It is the task of the Architect to consider all facets of building performance at the earliest stages of design … whether a small building, or a very large complex building … and to integrate those many diverse, but interdependent, facets into a coherent architectural statement … having a conceptual single crystalline shape … while also bearing in mind ‘person-centredness’, ‘flexibility’, ‘adaptability’, ‘accessibility for all’, and a ‘long and useful life cycle’.
[ An aside … closer to home … we are now witnessing the rise of the ‘Passive House Designer’. This person, who is able to use a specific computer software package … no less, and no more … need not necessarily be an architect, or have any architectural education/training. Is it possible to refer to the realized output from this software as ‘architecture’ … or are they merely drab, boring boxes ?? ]
3. Sustainable Buildings, Fire Safety & Fire Engineering ?
In the elaborate Amory Lovins Visitor’s Guide above … there is only one mention of fire hazard in the building … and that is in relation to a Passive Clothes Dryer (Page 40). End of story with regard to the Fire Safety Issues for its Users … and the Fire Engineering Implications arising from a chosen architectural design and chosen construction materials and methods.
When I was referring to a centrally located service room in # 2(iii) above … that room should also be structurally hardened, and fire and smoke ‘separated’ from other spaces in the house. Or … if the service equipment is located in a roof space, there are implications for roof structural reliability in a fire situation, and the fire resistance of the ceiling construction beneath. Or … if the equipment is located in a basement, a simple intermediate timber floor construction overhead is inadequate.
Furthermore … an intelligent fire detection and warning system … and a suitable domestic fire suppression system … are no longer luxuries or optional extras, but essential requirements ! Who would want to lose such a valuable investment ??
And insofar as fire safety issues are not being considered … it seems, at all … in the case of most ‘high-tech’, sustainable buildings … and certainly not in the case of the Lovins House … the Architectural Design Concepts for these buildings ‘suffer’ from a gaping hole … an enormous void … they are incomplete and, therefore, entirely inadequate.
Fire Engineering involves much, much more than mere compliance with building regulations and codes … whose fire safety objectives are limited, and whose performance requirements are sometimes inadequate and always minimal.
Unfortunately … there is a fundamental conflict between Sustainable Building Design Strategies and the current state-of-the-art in Fire Engineering Design. As an example … for cooling, heating and/or ventilation purposes in a sustainable building, it is necessary to take advantage of natural patterns of air movement in that building. On the other hand, fire consultants in private practice, and fire prevention officers in Authorities Having Jurisdiction (AHJ’s), will demand that building spaces be strictly compartmented in order to limit the spread of fire and smoke … thereby dramatically interfering with those natural patterns of air movement.
In everyday practice, there is a vast chasm in understanding and communication between these two very different design disciplines. As a result, serious compromises are being enforced on Sustainability Performance. If, on the other hand, adequate independent technical control is absent on the site of a Sustainable Building … it is the fire safety and protection which is being seriously compromised.
A range of critical fire safety issues (fatal, in the case of firefighters) are also arising from the Innovative Building Products and Systems being installed in Sustainable Buildings.
And because the emphasis is on pre-construction design ‘intent’ rather than the ‘real’ performance of the completed and occupied building … all of these problems are being conveniently sidestepped or ignored … and they remain hidden from everybody’s view.
Sustainable Fire Engineering Design, on the other hand, is the creative response to Sustainable Design … and the powerful drivers of Climate Change Adaptation, and Energy Conservation/Efficiency in Buildings.
Sustainable Fire Engineering Design Solutions are …
- Adapted to Local Conditions … Geography, Climate (change, variability and severity swings), Social Need, Culture, and Economy, etc., etc ;
- ‘Reliability-Based’ … the design process is based on competence, practical experience, and an examination of ‘real’ extreme events, e.g. 2001 WTC 9-11 & 2008 Mumbai Attacks, and 2011 Fukushima Nuclear Incident … rather than on theory alone ;
- ‘Person-Centred’ … ‘real’ people are placed at the centre of creative endeavours and proper consideration is given to their responsible needs … and their health, safety and welfare … and security … in the Human Environment.
Sustainability … continues to fundamentally transform our Fire Engineering, Architectural and Consultancy Practice at Sustainable Design International Ltd (SDI) !
2013-05-23: The U.N. Secretary-General, Ban Ki-Moon, announced the launch of the United Nations Sustainable Development Solutions Network (SDSN) on 9 August 2012.
UN SDSN is structured around 12 Thematic Groups of scientific and technical experts – from academia, civil society, and the private sector – who work in support of Sustainable Development Problem Solving at local, national, and global scales … and to identify and highlight best practices. They also provide technical support to the High-Level Panel of Eminent Persons on the Post-2015 Development Agenda.
The world has changed profoundly since the year 2000, when the UN Millennium Declaration and the Millennium Development Goals (MDG’s) were adopted by the United Nations. Four critical shifts make the coming fifteen-year period, 2015-2030, different from the MDG period, 2000-2015: (i) a drastically higher human impact on the physical Earth; (ii) rapid technological change; (iii) increasing inequality; and (iv) a growing diffusion and complexity of governance.
These problems will expand, dangerously beyond our control, without an urgent and radical transformation in how we organize society. The world now needs an operational Sustainable Development Framework which can mobilize all key actors (national & local governments, civil society, business, science and academia) in every country to move away from the Business-as-Usual (BaU) Trajectory towards a Sustainable Development (SD) Path. This Framework and the SDG’s identify the main objectives and strategies needed to transform from BaU to SD.
The purpose of the Sustainable Development Goals (SDG’s) is to help translate global aspirations into practical actions. In this regard, SDSN has subscribed to the ‘Rio+20’ Agreement that the SDG’s should be ‘action-oriented, concise and easy to communicate, limited in number, aspirational, global in nature and universally applicable to all countries while taking into account different national realities, capacities and levels of development, and respecting national policies and priorities’.
SDI’s Comments on the Draft ‘Action Agenda for Sustainable Development & Sustainable Development Goals’ …
[ Submitted by e-mail, yesterday (2013-05-22), to the U.N. Sustainable Development Solutions Network.]
1. The problems with this Draft Document, dated 7 May 2013, are fundamental and profound. Our Organization will be happy to assist the Network (SDSN) in improving the text.
2. At this time, however, we would like to bring to your attention some urgent overarching issues:
- Amend the Title … refer directly to the Sustainable Development Goals (SDG’s). See above.
- As drafted, the text does not show that … or explain how … there is a robust Interdependence between the different Sustainable Development Goals.
- Indeed, the scale and immediacy of the Sustainable Development Challenges are unprecedented. The Network (SDSN) must now, therefore, take the brave and difficult step of placing the Sustainable Development Goals in order of priority. Do not allow yourselves to be shackled by the approach taken in the earlier Millennium Development Goals !
- In this Document, All of the texts dealing with ‘Governance’ are ambiguous, weak and embarrassingly inadequate. References to the Institutional, Political, Legal and Judicial Aspects of ‘Governance’ are both necessary, and required.
- The word ‘access’ is used very often and very generally in the Document. BUT … in order for People with Activity Limitations (2001 WHO ICF) to ‘access’ facilities and services in the Built (including Virtual), Social and Economic Environments, and to be included and participate fully in their local communities … it is an ESSENTIAL prerequisite that those Environments are effectively ACCESSIBLE-FOR-ALL ! This concept is not mentioned once in the Document … a very serious omission.
Updates: 2013-06-07 & 2013-07-22 …
The SDSN Final Report is Fundamentally and Profoundly INADEQUATE !

” Twenty years ago this June, the World Conference on Human Rights convened at Vienna to forge a new vision for our world, one founded on a recognition of the fundamental interdependence between democracy, development and human rights. In the tail of a blood-stained and deprived century, the whispered call was for dignity, equality, justice, rights. And what began as a murmur in Vienna grew in volume and force with each global conference: Copenhagen and Beijing in 1995, Durban in 2001, New York in 2005 and again in 2010, and Rio in 2012. In recent years, the murmur has become a roar, echoing across societies on all continents, from victims denied redress, older persons denied respect, youth denied hope, and activists demanding a better way. From this call, we have learned much about the imperatives of sustainable development. There will be no development without equality, no progress without freedom, no peace without justice, no sustainability without human rights.”
“All that is required is the political will to move beyond the failed approaches of the past, to chart a fresh course, and to embrace a new paradigm of development built on the foundation of human rights, equality and sustainability.”
1. The Post-2015 Agenda must be built on a human rights-based approach, in both process and substance.
2. The new agenda must address both sides of the development challenge – that is freedom from both fear and want.
3. The imperative of equality must underpin the entire framework.
4. Marginalized, disempowered and excluded groups, previously locked out of development, must have a place in the new agenda.
5. We must commit to ending poverty.
6. The new framework must advance a healthy environment, as an underlying determinant of internationally guaranteed human rights.
7. The Universal Declaration of Human Rights guarantees the right to an international order in which human rights can be fully realized. Similarly, the UN Declaration on the Right to Development mandates international reform to ensure human rights-based policy coherence at the international level. In the wake of the global financial, food, climate and energy crises, and in the context of growing disparities and historic governance failures at all levels, the credibility and effectiveness of the Post-2015 Agenda will therefore depend also on the degree to which it addresses this pressing need for human rights-based reforms at international level.
8. The Post-2015 Agenda should be universally applicable.
9. The Post-2015 Agenda must include a strong accountability framework.
10. In the wake of the devastating global financial crisis, and revelations of abusive business practices in all regions, it is clear that responsibility for human rights-based development in the Post-2015 period must extend to actors in the private sector, as well.

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.

NIST TN 1792 – Summary & Conclusion (Page 59)
Radio Frequency (RF) PASS Tests were performed in a New York Subway Station and the Empire State Building because these types of structures provide challenging RF propagation-channel environments. In the Subway, the RF PASS systems were limited in their ability to communicate beyond the initial entrance level. Without the use of repeaters, most of the systems could communicate only a short distance beyond the bottom of the stairwell that connected the token booth corridor to the street. Two systems used repeaters to extend the coverage area. When a repeater was located at the base of the stairwell leading up to the street, those two systems were able to communicate the RF PASS alarms between the street level and the first passenger platform. However, with only a single repeater, neither of the two repeater systems was able to communicate between the external receive site and the second passenger level. This suggests that for structures with sizable subterranean sections, a repeater system will likely be required to reach an external incident command post. If the structure has multiple subterranean levels of increasing depth, a multiple-hop relay system will likely be necessary to ensure the reliability of the communication channel.
In the path-loss measurements and analysis performed at five frequencies, ranging from 430 MHz to 2405 MHz, there are several important insights. Based on the upper adjacent values in the box-plot statistical representation of the path-loss data from the Empire State Building (see Figure 36), path-loss values of 140 dB to 175 dB are possible for high-rises. For the Subway, the path-loss values exceed 210 dB to 240 dB at the lower two passenger platforms (see Figure 35). The frequency dependence is more pronounced for the Empire State Building results, but less apparent in the Subway data. Thus, while a system may function well at the lower end of the frequency spectrum in the above ground portions of a large building, the subway results demonstrate that subterranean structures can cause path-loss values greater than 200 dB across the 430 to 2400 MHz range.
The testing completed here focused on RF PASS system performance and RF propagation-channel measurements in a high-rise and subway station. While a primary goal of the effort was to look at the correlation between the system performance and path-loss behaviour, a secondary goal was to gather path-loss data in two high-attenuation settings. Thus, parameter values for log-normal distributions that will allow simulation of the measured path-loss conditions are included in this report. The authors hope that the data presented here, along with future sets of data, can be used to develop a complete suite of test methods, not only for RF-based PASS systems, but also for other RF-based electronic safety equipment. The path-loss values obtained here are general and could be used to develop standards for other equipment as the need arises for standards for these systems.
In Ireland … 10 UHF Channels have been allocated to the Fire Services for use with hand portable radios …

Taking a photograph is a distraction from the ‘real’ experience … it fails to capture and communicate the ‘person-centred’ feeling …
And I can imagine more comfortable words to describe this scene … ‘spiritual’, ‘transcendental’, ‘metaphysical’, ‘mystical’, ‘supernatural’ …
