2004 Rio de Janeiro Declaration on Sustainable Social Development, Disability & Ageing  (Download PDF File, 306 Kb)

The words ‘green’, ‘environmental’, ‘ecological’ and ‘sustainable’ are becoming part of everyday language in the Developed World, but are frequently interchanged without understanding.  To date, however, the concept of Sustainable Development has been hijacked by Environmentalists.  For example, no connection at all may be seen between a ‘sustainable’ building and ensuring that it can be safely and conveniently entered and used by ordinary people.

In other parts of the World, the ambiguous WCED / Brundtland Definition of Sustainable Development is being systematically rejected ;  the concept is viewed as an unaffordable luxury and/or as a means of continued domination and control by the ‘North’.  Yet, sustainability must be a global compact.

In this intolerant and more fundamentalist 21st Century, the United Nations System, International Law, and Social Justice continue to come under sustained attack.  And the Beslan School Tragedy* demonstrates that it is far more hazardous for disadvantaged, vulnerable and indigenous peoples in every society.

[ * The 2004 Beslan School Massacre … https://en.wikipedia.org/wiki/Beslan_school_siege … and its commemoration 10 years later … https://www.rt.com/news/183964-beslan-school-hostage-crisis/ ]

Some specific objectives for the 2004 Rio Declaration were as follows …

  • To present a 2nd Generation Definition of Sustainable Development which is more acceptable to the Developing World ;
  • To restore primacy to the Social Aspects of Sustainable Development … and particularly the ethical values of Social Justice, Solidarity and Inclusion-for-All ;
  • To embed the concept of the ‘Person’ in Sustainable Development … rather than the fleeting reference to ‘People’ which too often results in Disadvantaged, Vulnerable and Indigenous Groups being left behind ;
  • To signal one of the main challenges of Sustainable Development ahead – which will be to establish a framework of horizontal co-ordination at the many institutional levels … and between the many actors and end users … in the human environment.

Adopted in December 2004, at the Brazil Designing for the 21st Century III Conference, the Rio Declaration consists of a Preamble, 10 Principles and 5 Appendices ;  its central concern involves People with Activity Limitations (2001 WHO ICF).

This Declaration extols implementation, and the targeting and monitoring of ‘real’ performance – as opposed to ‘imagined’ or ‘paper’ performance.

LEED, PassivHaus & BREEAM Housing ~ Atrocious Fire Safety !!

Posted by CJ Walsh

2016-04-11:  It Happened One Night !

And Maybe … if it hadn’t been that particular night, during all the festivities of New Year’s Eve 2015, we would never have heard about the Address Supertall Hotel Fire, in Dubayy (UAE).  A long search on the Internet afterwards led to the detailed, post fire analysis report on the 2014 Lacrosse Docklands Fire, in Melbourne (Australia) … followed by some more searching, and a very large can of worms opened up … similar nasty façade (external fabric) fires in many, many countries … involving large chunks of flaming debris falling from terrific heights, carried by the wind to a significant distance away from the building of fire origin.

Some people have tried to suggest that the only reason for these fires is inadequate building codes/regulations.  No … the reason for these fires is much more than that … it’s the ‘SYSTEM’ !   In other words, how the International Construction Sector is organized and goes about its ordinary, everyday activities and tasks.  We must also talk about poor quality design and construction … and a lack of stringent, independent enforcement of effective building codes/regulations and standards.  I have written this down many times before … Self-Regulation is NO Regulation !!

It is very clear that Conventional Fire Engineering … as currently practiced, internationally … is no longer ‘fit for purpose’.  For discussion at SFE 2016 DUBLIN.  Check out the Fire Conference Website: www.sfe-fire.eu … and on Twitter: @sfe2016dublin

IN IRELAND … A 2015 TERRACED HOUSING FIRE …

The general public was shocked and stunned, to put it mildly, by a very rapid and extensive 2015 Terraced Housing Fire on the outskirts of Dublin …

[ See my Blog, dated 2011-04-06 … about a different, but related, 2011 Terraced Housing Fire in Terenure, a suburb of Dublin City.]

[ Fast forward from 2011 … overtaking Priory Hall (see my series of Blogs) … to Longboat Quay, a large residential development on the south bank of the River Liffey, which flows through the middle of Dublin.  A recent visual/surface inspection of one of the units there revealed not just a poor quality of construction … but a lack of care and attention, with a mixture of incompetence and ignorance thrown in for good measure.]

The 2015 Terraced Housing Fire, shown above, should not have been a surprise to the ‘System’ in Ireland.  Research carried out in the U.S.A., Belgium and The Netherlands since 2012, and a serious PassivHaus Apartment Fire in Köln, Germany, on the night of 5 February 2013  … have all shown that the modern home (highly insulated, airtight, packed with electronic equipment and wiring, and fast-burning synthetic furnishings, etc.) is the ‘perfect storm’ of fire conditions and outcomes.  More open residential design + increased fuel loads + new construction systems and materials = faster development of fires, much reduced times to flashover, far less time for occupant evacuation, particularly people with activity limitations … and shorter building collapse times.

The time to flashover in modern high-performance housing, i.e. Sustainable/Green/PassivHaus/Eco/LEED/Bio/+Energy/Low Carbon/BREEAM/Zero Carbon/SMART … can be 7 times faster than in conventional/legacy housing … or less than 5 minutes, compared with just over 29 minutes !

All of this research can be found on the Links & Docs Page of the SFE 2016 DUBLIN Website.

Let us be crystal clear … there is nothing Sustainable/Green/PassivHaus/Eco/LEED/Bio/+Energy/Low Carbon/BREEAM/Zero Carbon/SMART about the post-fire scenes of destruction shown above.  And only for the physical separation between terraces, which can be clearly seen in the last photograph … the fire would have kept spreading.

.

URGENT FIRE SAFETY RECOMMENDATIONS …

Without a balanced, proper approach to the issue of Fire Safety in this type of modern, high-performance housing … occupant safety is seriously threatened.  And if, in the event of a fire incident, the occupants are asleep … or people with activity limitations are living in the house … that threat will be extremely grave indeed.

Reality – Reliability – Redundancy – Resilience !

So … what needs to change ?   In Ireland, our immediate problem is Timber-Framed Housing (as shown above) … and the following is an outline of what must change … NOW !

  1. Party Walls, i.e. the walls separating one house from another, must be constructed of solid masonry, with a uniform and uncompromised thickness of at least 200mm … plastered on both sides, not dry-lined, for adequate smoke resistance … and be continued above the roof covering for at least 300mm.
  2. An effective Fire Detection System must be installed.  The conventional ‘package’ of one smoke detector per floor in the hallway and staircase of a standard 2 storey semi-detached house is nowhere near being adequate.
  3. An effective Residential / Domestic Fire Suppression System must be installed, e.g. low pressure water mist.  See later post, dated 2016-06-13, for a costed notional installation.
  4. If there is a Controlled Ventilation System, either mechanical or natural, in the house (for the purposes of air quality, heat exchange and energy conservation), it must be linked to the fire detection system.  In the event of a fire incident, the Ventilation System must immediately cease operation, and remain ‘fully open’.  This is in order to mitigate the build-up of high positive pressure, within a confined airtight space, caused by a developing fire … and to provide an exhaust route for smoke and toxic gases … during the short period of time prior to activation of the fire suppression system.
  5. Intermediate Timber Floors and Evacuation Routes, including fire resisting doorsets, must be reliably protected from fire and smoke.  The minimum period of fire and smoke resistance must be linked to local fire service support infrastructure.  In other words, the local fire services must be allowed sufficient time to arrive at the scene of a fire in strength … to search for any occupants still remaining in the fire building … and to bring the fire under control.
  6. Uppermost Ceilings under a trussed timber roof structure, including any trap doorsets into the roof space, must be similarly and reliably protected from fire and smoke.  Once fire enters a roof space, the light trussed timber structure will collapse within a few minutes.
  7. Front and Back Entrance/Egress Doors must be outward opening.  In the 2013 German PassivHaus Apartment Fire, the occupant found it extremely difficult to open inward opening doors and windows because of the high positive pressure caused by the developing fire.  This unusual phenomenon was confirmed in the 2015 Finnish Apartment Fire Tests, when much higher positive pressures were observed.
  8. Internal Linings of External Walls must comprise 2 layers of plasterboard, with all joints staggered … steel fixed, at not more than 150mm centres.  Once fire breaches the internal lining of an external wall, the whole building will become involved in the fire.  Horizontal and vertical fire sealing behind these linings, even if properly installed (!), are too little and too late.
  9. Frontline Firefighters must be supported by specialist structural engineering and hazard appraisal units … and light/portable/reliable Thermal Imaging Cameras must be recognized as a standard tool of firefighting.

.

SUSTAINABLE HOUSING & RESIDENTIAL BUILDINGS …

These building types are more popularly known as Green, PassivHaus / Passive House, LEED, Eco, Bio, BREEAM, +Energy, Zero / Low / Nearly Zero Carbon, or SMART, etc., etc, etc.   In ALL of these cases, however, an Effective Residential Fire Suppression System MUST BE INSTALLED, e.g. low pressure water mist !

In everyday practice … Authorities Having Jurisdiction (AHJ’s), and the Organizations and Individuals responsible for the far-too-rapid construction of these innovative building types are either completely and blissfully ignorant, or callously and negligently in denial, about the seriously negative impacts on Occupant & Firefighter Fire Safety and Building Fire Protection.

BUT … slowly … more and more reliable evidence is being gathered !   Please visit the Links & Docs Page on: www.sfe-fire.eu … and also view this Presentation on some very interesting 2015 Apartment Fire Tests in Finland: www.youtube.com/watch?v=0Ss_ONolzLY

.

ENERGY CONSERVATION & EFFICIENCY UPGRADING OF EXISTING BUILDINGS …

In refurbishment projects where insulation is fixed to the internal surfaces of external walls … similar fire safety problems exist, and they must be solved by reviewing the full checklist above.  Refer again to the PassivHaus Apartment Fire in Köln, Germany, on the night of 5 February 2013 … and to the 2015 Apartment Fire Tests in Finland

Sustainable Buildings – Design Agenda for the 21st Century ?

Posted by CJ Walsh

2009-05-06:  From the late 1980’s and the beginning of the 1990’s in European Union (EU) Research Programmes, it was noticeable that the more pressing early concerns about Energy-efficiency – logical after the oil crises of the 1970’s – were beginning to merge with those of Environment-friendliness, i.e. protection of the environment.  Even at that time, however, faint background references to Sustainability were becoming more common.

 

In 1995, therefore, Sustainable Design International developed and introduced the acronym ‘SEED’ … which stands for Sustainable, Environment-friendly, Energy-efficient Development … as a practical control, or check, on our own work output.

 

 

The next break-through came a few years later.  I briefly discussed the wide conceptual basis for our Corporate Design Philosophy in the post: ‘Sustainable Human & Social Development ?’, dated 2009-03-31.  This basis, while still continually evolving, is critical in terms of services provided, performance targets to be achieved, methods of working and relationships with client organizations, builders, craftsmen/women, manufacturers, etc.

 

This should explain the futility, in our humble view, of the ‘Green’ Agenda (as distinct from the ‘Sustainability’ Agenda) … and approaches based solely on Environmental Aspects of Sustainable Development.  They are a complete waste of time and resources.

 

 

Now in 2009, we remain fully convinced that Sustainable Design Solutions are appropriate to local geography, social need, climate, economy and culture … and are ‘person-centred’ and ‘reliability-based’.

 

Forget the images of mud housing and reading by candle light … the Future of our Built Environment is High-Tech, Smart … and Sustainable !   Let there be no doubt !!

 

 

 

Why not begin, so, by looking at a Simple Building Type … Sustainable Housing ?

 

With all of the current hype and fuss about German ‘Passiv’ Houses and Austrian High-Tech Timber Framed Construction … we have been in contact with a number of manufacturers in this region of Central Europe.  After many meetings and detailed discussions, we are disappointed … broken hearted !

 

Below follows our shopping list for the practical, commercial and affordable application, i.e. non-research, of Advanced Systems of Construction (small/medium/large scale projects – new-build and existing projects).

 

N.B.  Current Irish legal requirements and local authority technical control procedures are entirely inadequate.

 

Is anybody out there listening ???

 

 

 

To meet the urgency of Climate Change Adaptation and the challenge of Reliable Sustainability Implementation … a ‘SEED’ Building in Ireland must reach these performance targets:

 

–         be set in Sustainable Landscaping (where appropriate) with Life Cycle Sustainable Drainage … and exhibit a considered, harmonious relationship between the building’s ‘interior’ environment and the ‘exterior’ built and social environments ;

 

–         have a Minimum Building Life Cycle of 100 Years ;

 

–         be Smart/Intelligent, Electronically Mature and facilitate Remote Building Management ;

 

–         be properly shown to be Fit for Intended Use (in the Location of Use) … by CE Marking, using European Standards/Norms & European Technical Approvals (refer to Part D of the Irish Building Regulations and similar requirements in other European national building codes, European Union Safety at Work and Product Liability Legislation) ;

 

–         be Super Energy-Efficient, with negligible thermal bridging and accidental air seepage … and promote and encourage, by design, Energy Conservation ;

 

–         have a substantial component of Renewable Energy & Heat Technologies … sufficient to return a multiple of the building’s energy consumption to an Intelligent Regional or District Grid … and also incorporate Recycling, Rainwater Re-Use and Waste Management Technologies ;

 

–         offer a high level of Indoor Air Quality, including proper protection from Natural Radon ;

 

–         be Flexible and Adaptable with regard to internal layout, and Accessible for People with Activity Limitations (2001 WHO ICF) – in order to prolong Building Life Cycle and maximize Building Usability ;

 

–         contain, as standard and for reasons of safety, a Domestic Sprinkler System and a remotely monitored Fire Detection System … plus a Carbon Monoxide (CO) Detection System, with a detection unit in the vicinity of each fuel burning appliance ;

 

and

 

–         be Competently Built and Reliably Completed to project programme and cost estimate … with the building’s ‘Real’ Performance-in-Use capable of being tested, and continually monitored, over the complete building life cycle ;

 

and

 

–         be simple and straightforward for Building Users/Occupiers to operate.

 

 

 

Principal Areas of Inadequate Performance …

 

1.  Showing Fitness for Intended Use.  Although a Single European Market for the Construction Sector exists on paper (not yet in reality) … this requirement is not well understood by manufacturers … particularly in Germany and Austria, where outdated national approaches to building product/system approval still take precedence over anything at European level.

 

2.  Domestic Sprinkler Systems.  There is a high level of resistance, among most manufacturers, to the installation of these systems.  Not acceptable !!

 

3.  Accessibility of Buildings for People with Activity Limitations.  Not well understood by manufacturers and building organizations (at all levels).  Although there is a lot of legislation in Europe covering this particular issue … it is routinely disregarded and/or very poorly implemented.  In Germany and Austria, for example, the long outdated term ‘barrier-free design’ is still in common use.  Can you believe that ?

 

4.  Radon Protection of Buildings.  Not considered important in Germany and Austria … so manufacturers just don’t bother.

 

5.  Fabric Thermal Performance.  Where building systems are ‘adapted’ for use in Ireland, I have seen thermal performance, as originally designed in Germany/Austria, seriously compromised by the installation of meter boxes and permanent ventilation openings in external walls.  Just the tip of the iceberg !
