Flexibility

Urgent ! … Next Generation Architectural Design Concepts

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 !) …

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) !

Driving Harder & Deeper Into Sustainable Development !?!

2013-01-13:   The 13th … a lucky day !

As we drive harder and deeper (at least some of us anyway ?) towards a future of Sustainable Human & Social Developmentor 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 …

The Type of Lightweight Development in the foreground of the photograph below … damaged beyond repair or re-construction during Hurricane Sandy, is not Resilient … which is a different concept to Robust, or Robustness.

Notice the building in the background, on the left, which appears to have survived fully intact … why ??

It will be ridiculous, and the height of stupidity, to repair/replace buildings and infrastructure using similar methods of construction. Will Insurance Companies and Federal/State Authorities understand this ?? Click to enlarge.

.

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

So … what is a Resilient Human Environment … particularly in the context of Sustainable Climate Change Adaptation ?

What do we mean by Transforming Social Organization ??

And … as we drive forward, harder and deeper … why is it critical that we practice a balanced, synchronous approach … across ALL Aspects of Sustainability … to Tangible Sustainability & Climate Resilience Implementation ???

Let us confront some more interesting new words and thought-provoking concepts …

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 resilient socio-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 and surprise 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.
