Important New Publication: ‘Heritage – Driver of Development’

2013-06-09:  Further to yesterday’s post … and my use of the phrase ‘Adapted to Local Context and Heritage (fr: le Patrimoine)’ … in relation to Sustainable Fire Engineering Design Solutions … or, indeed, Sustainable Design Solutions generally …

The International Council on Monuments and Sites (ICOMOS) … has just published the hard-copy version of … ‘Le Patrimoine, Moteur de Développement : Enjeux et Projets … the proceedings from the 2011 ICOMOS International Scientific Symposium, which was held in conjunction with the 17th ICOMOS General Assembly in early December 2011 … and organized by ICOMOS-France (www.icomosfrance.fr).

This bilingual (French and English) document provides a summary of the 4 Main Issues discussed during the Paris Symposium.

Manifested here … is a profound re-imagining of the concept of ‘heritage’, and its symbiotic relationship with ‘local context’ … which also now facilitates a synergetic fusion of ‘heritage’ with mainstream sustainable development theory and implementation.  I have highlighted key passages …

HERITAGE – DRIVER OF DEVELOPMENT

The Theme of the International Scientific Symposium, which forms part of the ICOMOS General Assembly, is the role of heritage in the creation of tomorrow’s society.

The effects of globalization, which are manifested in growing trends towards standardization and westernization, bring various forms of instability to human societies.  Until now, heritage has been confined to the role of passive conservation of the past, and so has often been seen as a burden hindering development.  In the future, it should be called upon instead to play a major role, re-establishing cultural identity and diversity as key reference points for development; these factors are currently endangered, yet vital.  There is therefore a need to reassess the role of heritage in a constructive way.

The concept of heritage, which ranges from designated historic monuments to a jumble of memories, first needs a clear definition which identifies its inherent nature and sets out its boundaries and limits, now and in the future.

As it would be impossible to cover all these issues at the Symposium, it is proposed to focus on the following four issues, chosen for their fundamental importance or contemporary relevance …

1.   Regional Development

As more and more people abandon small towns and the countryside, migrating to large conurbations, urban development has become anarchic, ad-hoc and difficult to control.  This has already had serious, even catastrophic, results … in particular:

–   The disruption of spatial scale and the loss of landmarks ;

–   The breakdown of social relationships, loss of communal solidarity, concerns over security, extremist and violent demonstrations ;

–   An imbalance between the city – where most concerns now focus and where most development projects take place – and the countryside, where the issue is no longer merely rural decline, but rather the complete socio-economic and cultural collapse of forgotten populations ;

–   The squandering and trivialization of space, which is a non-renewable resource, and in particular the loss of landscapes and farmland, resulting from both extensive urban encroachment and land being left to lie fallow.

It is vital to return to a more balanced form of development.  This will be achieved by replacing the principle of urban expansion with that of regional development, which takes into account both the countryside and secondary urban centres (small and medium-sized towns), as part of a balanced network.  In this context, lessons from our heritage will again be valued as an inspiration for new developments: time-honoured frameworks, traditional plot sizes, methods of organization (urban historic core zones), communication (by land – rail – water), and energy generation (small-scale solar and hydroelectric power stations), etc.

2.   Sustainable (Human & Social) Development – Return to the Art of Building !

The second half of the 20th Century was marked by the frantic exploitation of fossil fuels and is credited with the international spread of Western lifestyles and buildings, said to represent ‘progress’ but nevertheless creating a decisive break with traditional models.  The goals we have today for energy saving and recycling require a fundamental change in the character of both new and old buildings, in line with the following three points:

–   Expertise in Re-Use.  Until the 1950’s, heritage buildings – especially vernacular ones – provided countless examples of successful adaptation to the physical environment (location, orientation, protection from sun, wind, and climate); use of local materials (earth – wood – stone, etc.); traditional techniques providing / guaranteeing the greatest opportunities to acquire and perfect artisanal skills; and an optimum capacity for recycling.  The resulting buildings address today’s requirements for sustainable development particularly well.  Where historic buildings are capable of residential re-use according to modern sustainability criteria, we must be able to measure and maximise their current performance before adapting them according to new artificial design standards.

–   Expertise in Building.  In terms of new construction, recent examples have shown the ability of traditional practices to create architecture that is indisputably creative and modern/contemporary, and offer an alternative to artificial solutions proposed in response to new standards.

–   Adapting to Sustainable Living.  Rather than putting the entire onus on the built heritage, we must question our expectations about comfort and utilization.  We need to abandon attempts to use sites for activities for which they are fundamentally not suited; modify usage according to the seasons (closing down places that are difficult to heat in winter); and, finally, reconsider our demands in terms of comfort, which have grown excessively and unreasonably over the last decades.  The progress that would be made in the fields of environmental and public health is well known.

3.   Development and Tourism

Heritage is a major part of the tourist industry, but at the same time, because of the mass consumption to which it is increasingly subject, it runs the risk of becoming meaningless, by fluctuating between preservation of museum pieces and theme-park caricatures.  Cut off from its context, the real significance of heritage is drowned out by a feeble reflection, and its very nature is altered by excessive numbers of visitors and the facilities installed for them.

Several courses of action are available, among others:

–   Rendering identification with cultural heritage tangible … by revealing and interpreting heritage in all the richness of its context and distinctiveness, and by encouraging public awareness of history through education and the wider media.

–   Controlling public access … so as both to limit physical erosion and to ensure the comfort of visitors and provide the best conditions for them to understand and appreciate the value of heritage.  Some preliminary reports on trials successfully undertaken at a number of buildings and Grands Sites [designated French cultural landscapes] may help in developing guidelines.

4.   Economics of Development

“The Amphitheatre at Nîmes and the Pont du Gard have brought more to France than they ever cost the Romans.”  This quotation from Abbé Grégoire in the second year of the French Republic remains valid today.  Investment in our heritage produces particularly attractive returns.  The cultural sector fully understands this, but adopts methods that tend to be rather commercial.

This investment must be better directed, by identifying targets and striving more for qualitative results rather than short-term profits.

Upcoming Building Research Workshop at Galway University

2013-06-08:  Looking forward to some serious, collaborative and multi-disciplinary discussions on the day … and a barrel of laughs in the process (!!) …

The Informatics Research Unit for Sustainable Engineering (IRUSE) in the Department of Civil Engineering … and The Ryan Institute for Environmental, Marine and Energy Research … both at the National University of Ireland Galway (NUIG) … have jointly organized a 1-Day National Research Networking Workshop which will take place on Monday, 24 June 2013.

The NUIG ‘blurb’ for the day states … “Considering the importance of aggressive energy-efficiency measures in the Building Sector, together with the requirements for a safe, healthy, comfortable (and accessible) Built Environment … this NUIG Workshop will explore the topic of Integrated Modelling and Performance of the Built Environment.”

.

I was very pleased to receive an invitation to make a Presentation at this prestigious event …

‘Sustainable Fire Engineering Design’  –  My Presentation Abstract

Fire Engineering … involves 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.  More problematically … a fundamental conflict is mushrooming between Safe Sustainable Climate Resilient Building Design and Conventional Fire Consultancy Practice.

However … Sustainable Fire Engineering Design Solutions are:

  • Reliability-based ;
  • Person-centred ;

and above all

  • 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.

This Presentation will discuss very rich collaborative research potential in the following areas …

  1. Creative Fire Engineering Concepts and Building Systems
  2. Fire-Induced Progressive Damage in Buildings
  3. Human Behaviour and Abilities in a Fire Situation
  4. Building Design for Firefighter Safety
  5. BMS – Fire Modelling – BIM

Research Output must be targeted at practical implementation in ‘real’ buildings … with actual user/construction performance carefully (i.e. reliably and precisely) monitored !

.

If anybody out there is interested in attending this NUIG Research Workshop … please contact Ms. Magdalena Hajdukiewicz (IRUSE) at: hajdukiewicz1@nuigalway.ie

POST-EVENT UPDATE:  2013-06-27 …

While it was difficult to keep the Workshop Programme, involving a series of short 10-minute presentation slots, on track … discussions during the day were engaging, energetic and extensive.

I happily look forward to a successful and collaborative outcome from the day … Multi-Disciplinary Teams producing Trans-Disciplinary Research Output … which is geared towards practical implementation in ‘real’ buildings, with actual construction and building user performance carefully (i.e. reliably and precisely) monitored !

However … and especially since the Workshop had been organized by IRUSE (the ‘SE’ standing for ‘Sustainable Engineering’) … it was indeed very strange to have to clarify the following points, among others:

1.   The Minimum Life Cycle for a Sustainable Building is 100 Years … not 50 or 60 years !

2.   Future Research Collaboration should be targeted at the multi-aspect ‘Sustainability Agenda’.  The word ‘green’ (where only environmental aspects of sustainability are considered) should be actively discouraged, if not banned entirely !

3.   With regard to Good Indoor Air Quality (IAQ) … two high-level performance indicators which have been developed with the aim of protecting human health, and are both now referenced in International Standard ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’ … are …

      –   Radon Activity (incl. Rn-222, Rn-220, RnD) in a building should, on average, fall within the range of 10 Bq/m3 to 40 Bq/m3, but should at no time exceed 60 Bq/m3 ;

      –   Carbon Dioxide (CO2) Concentrations in a building should not significantly exceed average external levels – typically within the range of 300 parts per million (ppm) to 500 ppm – and should at no time exceed 800 ppm.

.

Galway University’s New Engineering Building

Concerning the substantive difference in meaning and scope between ‘sustainable’ and ‘green’ … there is, perhaps, no better way to illustrate this difference than to observe the atrocious ‘Accessibility-for-All’ Performance (Accessibility for People with Activity Limitations !) of the critically acclaimed (?!?) and award winning (?!?) New Engineering Building in Galway University … which flaunts its ‘über-green’ credentials …

Can you believe what’s in those photographs ??   More importantly … can you believe what’s not in those photographs ????   In such a recently completed building … “incredible” is the only answer to both questions.

.

Under International Law … lack of accessibility, or inadequate accessibility, to the social, built, virtual and economic environments … IS a denial and infringement of the basic human rights of people with activity limitations.  It also limits, needlessly and unnecessarily, the numbers of potential users of those environments … which makes no sense at all.

My strong recommendation to Galway University … is to immediately commission a Competent Accessibility Consultant to give the university campus a thorough going over !   You are failing the campus user population … the local community in Galway … and Irish society generally.

My even stronger recommendation to the Architects for the New Engineering BuildingRMJM Architects (Robert Matthew Johnson-Marshall) in Scotland, and Taylor Architects in Ireland … is to always commission a Competent Accessibility Consultant on all of your projects … small, medium and large … because you haven’t a bull’s notion about this important dimension of building performance !!

And remember folks … Accessibility has been clearly specified in the new International Standard ISO 21542 as including … ‘access to buildings, circulation within buildings and their use, egress from buildings in the normal course of events, and evacuation in the event of an emergency’.

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 !) …

European Commission - COM(2013) 169 final Cover

EU Green Paper – A 2030 Framework for Climate and Energy Policies

Click the Link Above to read and/or download PDF File (104 Kb)

.

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 ??

RMI / Amory Lovins House, Colorado, USA - Exterior - Roof Photovoltaic (PV) Panels
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.]

RMI / Amory Lovins House, Colorado, USA - Exterior - Tracking Photovoltaic (PV) Panel

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 !

RMI / Amory Lovins House, Colorado, USA - Interior - Building Services
Photograph taken by Judy Hill Lovins. Click to enlarge.

(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 ?

RMI / Amory Lovins House, Colorado, USA - Interior - Battery Array
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) !

RF-Based Firefighter Communication Performance in Buildings

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.

NIST TN 1792 - Figure 16: 'Subway + System 4 Performance'
NIST TN 1792 – Figure 16: ‘Subway + System 4 Performance’. Click to enlarge.

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.

2012 ‘Understanding China’ Policy Briefing Friends of Europe & EuroChambres

An estimated One Billion People will be living in China’s cities by 2030.  This large-scale and very rapid urbanization demands that a sustainable transformation of their urban built, social, economic and institutional environments commences Today – not at some notional point in a far distant future.

Furthermore … replicating a European approach to sustainable design and construction in other regions of the world is doomed to failure.  Urban Transformation in China must be adapted to Local Geography, Climate, Climate Change, Social Needs, Cultures, Economy, and Local Severe Events (e.g. earthquakes, flooding).  With European support and collaboration … China must, and will, find its own way.

2013 Asian Development Bank (ADB) Guidebook: ‘Increasing Climate Change Resilience of Urban Water Infrastructure’ 

This Guide describes a practical approach to bridge the gap between theoretical analyses of climate change impacts and the planning decisions that need to be made by city authorities and utility managers to increase climate change resilience of the water sector in the city of  Wuhan, Hubei Province, People’s Republic of China (PRC).  It focuses on answering the questions currently being asked by city planners and managers all over the world, as follows:

  • What changes might be caused by climate change ?
  • How will these changes affect services and utilities ?
  • What can we do now to prepare for them ?

The long lead time required to plan, finance, build, and commission city infrastructure facilities means that decision makers cannot wait for more detailed data on the effects of future climate change, especially those relating to local circumstances, but must make investment decisions based on what is known now and what can be readily predicted.  An important principle in this kind of ‘robust’ decision-making is provided by the  Intergovernmental Panel on Climate Change (IPCC)  tenet that adaptation investments, which move a city’s infrastructure toward sustainable development (such as providing safe drinking water and better sanitary conditions), are justifiable even without climate change.

This Guide is arranged in clear steps to provide direction and information for similar exercises in other areas.  Having grown out of a specific locality and its needs, the principles and solutions developed in this guide are founded on real world situations and problems …

***  THIS TALL BUILDING IN YUNNAN PROVINCE  &  SIMILAR COMPLEX ARCHITECTURAL PROJECTS  ***

Working within the professional constraints of ‘client confidentiality’ … it is possible to have a general discussion about current building design, construction and operation issues in an international sector which is operating, more and more, beyond national borders … without adequate, or very often any, national and local regulation.  By ‘regulation’, I mean a flexible system of building-related legislation which is operated in conjunction with mandatory and effective technical control.

In order to cope with today’s complex built environment and the enormous variation in the size and scale of construction projects … a ‘flexible’ mix of functional, performance and prescriptive legal requirements is the sharpest and most appropriate instrument.

And you can forget the hype about performance-based building codes coming out of the USA … hot air, and much ado about little !

Of course, the biggest issue of all is the competence of those individuals who work in Authorities Having Jurisdiction (AHJ’s), i.e. technical controllers.  Even in the most developed economies of the world … there are many occasions when the level of individual incompetence in an AHJ is astounding … and institutional arrangements within the AHJ itself are a mess, i.e. the AHJ is not fit for purpose.

.

1.  Sustainable Design – Design Process Efficiency & Proper Preparation for Construction

A tremendous amount of waste is associated with and generated by the processes of conventional building design, construction and operation.  There is a more up-to-date and efficient way of doing things … an essential way for Sustainable Design … and it’s called Building Information Modelling (BIM) !

Furthermore … consider, for a moment, just the initial list of Specialist Consultants who will be engaged directly by the Chinese Client when the project’s conceptual design has reached a sufficiently developed stage.  How can all of these individuals and organizations – listed in the revised and agreed Project Design Agreement – obtain accurate and reliable ‘real time’ information about the rapidly evolving project from a central design library / information database … then feed their new work back into the centre without unnecessary delay ?   How, next, can everyone else who needs to know, be updated with the new design input … again, without delay ?   And perhaps, these consultants may also be based in different countries … working in very different time zones …

  • Building Information Modelling (BIM) Consultant
  • Local Design Institute (LDI) … a local architectural practice which will produce the project’s working drawings, handle local spatial planning and building code approvals, carry out site inspections, and deal directly with construction organization(s), etc., etc.
  • Interior Design Consultant
  • Traffic / Parking Analysis Consultant
  • Curtain Wall Consultant (Curtain Wall, Skylights & Special Roof Structures)
  • Retail Market Analysis Consultant
  • Landscape Design Consultant
  • Quantity Surveying & Cost Estimating Consultant
  • Furniture Design Consultant
  • Geotechnical, Civil Engineering & Structural Engineering Consultant (including structural performance under fire and earthquake conditions, resistance to fire-induced progressive damage and disproportionate damage … and also including climate resilience)
  • Acoustic & Audio-Visual Design Consultant
  • Mechanical, Electrical & Plumbing (MEP) Engineering Consultant
  • Integrated Building Automation & Management / Telecom / Security / Networking Consultant
  • Fire & Life-Safety Engineering Consultant
  • Water Feature Consultant
  • Wind Tunnel Test Consultant
  • Kitchen Equipment and Layout Design Consultant
  • Art, Artefact and Accessories Consultant & Procurement Services for Art, Artefacts, and Accessories
  • Tenant Storefront Design Consultant
  • Helicopter Landing Pad Design Consultant
  • Universal Design / Accessibility for All Consultant [including access to the building, electronic, information and communication technologies (EICT’s), and services offered at the hotel … and including fire safety, protection and evacuation for all]

.

2.  The ‘Design Professional in Responsible Charge’ !

The Project Design Agreement requests that the Client receive advice on who might be the different Specialist Consultants listed above.  In addition, it will be necessary to demarcate the boundaries within which each Consultant will operate … and, where appropriate, to prescribe a design performance target (see below) for each speciality … which must be ‘realized’ in the completed and occupied building !

Recalling the many previous posts, here on this Technical Blog, concerning NIST’s 2005 & 2008 Recommendations on the 9-11 World Trade Centre Building Collapses in New York City‘somebody’ must ensure that the many individuals and organizations listed above – members of the Larger (2nd Stage) Design Team – use consistent design data and assumptions … must co-ordinate design documents and specifications to identify overlaps and eliminate gaps … must serve as ultimate liaison between the Client, the Local Design Institute, AHJ officials, and the Construction Organization(s) … and must ensure that everybody is on the same communication wavelength, and working towards the same objective in a trans-disciplinary manner.

That ‘Somebody’ … the Design Professional in Responsible Charge … must be the Project Design Architect !

.

3.  Some Sustainable Design Performance Targets

Actual construction and building user performance shall be carefully (i.e. reliably and precisely) monitored … and independently verified …

A.   Basic Functional Requirements … the Building shall comply with the Basic Requirements for Construction Works – elaborated in Annex I of European Union (EU) Regulation No.305/2011 of the European Parliament and of the Council, of 9 March 2011, laying down Harmonized Conditions for the Marketing of Construction Products and Repealing Council Directive 89/106/EEC.

See my Post, dated 2011-09-13 … https://www.cjwalsh.ie/2011/09/new-eu-construction-product-regulation-3052011-halleluiah/

.

B.   Good Indoor Air Quality (IAQ) … Two high-level performance indicators have been developed with the aim of protecting Human Health, and are both now referenced in International Standard ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’

      –   Radon Activity (incl. Rn-222, Rn-220, RnD) in a building should, on average, fall within the range of 10 Bq/m3 to 40 Bq/m3, but shall at no time exceed 60 Bq/m3 ;

      –   Carbon Dioxide (CO2) Concentrations in a building should not significantly exceed average external levels – typically within the range of 300 parts per million (ppm) to 500 ppm – and shall at no time exceed 800 ppm.

.

C.   Energy Conservation & Efficiency + A ‘Positive Energy’ Return + Assured Building User Thermal Comfort

‘Sustainability’ – New Part 11 in India’s National Building Code !

2013-03-17:  Happy Saint Patrick’s Day !!

Submissions on India’s Draft Amendment No.1 to the 2005 National Building Code (SP 7:2005) concerning the Proposed Incorporation of a New Part 11: ‘Approach to Sustainability’ had to arrive at the Bureau of Indian Standards (BIS), in Dilli … by e-mail … no later than Friday last, 15 March 2013 …

Indian National Building Code Proposed New Part 11: 'Approach to Sustainability' - Cover Memo
Click to enlarge.

Indian NBC, Proposed Part 11 on ‘Sustainability’ – December 2012 Consultation

.

Extract From Foreword (Page 7):

‘ Developed nations’ approach to sustainability generally concentrates on energy conservation through high technology innovations, and use of products, materials and designs with lower embodied energy.  Their green ratings are based on intent, which implies expert inputs and simulation.  The Indian construction industry will do better using our traditional wisdom and practices, building in harmony with nature through regional common knowledge, consuming as little as necessary, applying low cost technology innovations, using recycled materials, and recognizing performance (not intent) through easily measurable parameters wherever feasible.’

How Right They Are About Prioritizing ‘Real’ Performance !!

.

And Just Before That Extract Above:

‘ The authentic (my insert !) Indian way of life is aparigraha (minimum possessions), conservation (minimum consumption), and recycling (minimum waste).  These three attributes are the guiding principles for sustainable buildings as well.  With these attributes and its rich heritage, India can make a substantial contribution in this field and eventually lead the world on the path of sustainability.’

An Overly Ambitious Target ?   Perhaps Not.

.

SDI Supporting India’s National Sustainable Buildings Strategy …

We very much welcome this opportunity to make a Submission on India’s Draft Amendment No.1 to the 2005 National Building Code (SP 7:2005) concerning the Proposed Inclusion of a New Part 11 ‘Approach to Sustainability’.

This IS an important development for India … and it DOES mark a substantial contribution to this field, at international level.  We wish that other countries would follow your example … particularly China, the other mushrooming economies in South-East Asia, and the Arab Gulf States.

You may not be aware that Sustainable Design International (SDI) has been specializing in the theory and implementation of a Sustainable Human Environment (social, built, virtual, and economic) since the mid-1990’s.

And, for example … in September 2007, we were invited to make a series of Keynote Presentations to 20 Senior National Decision-Makers, from both the public and private sectors, at a 2-Day Workshop which was organized for us in Lisboa, Portugal.  If invited, we would be delighted to repeat this valuable exercise in Dilli, Bengaluru, and other suitable venues in India.

.

IF India is to lead the world on this particular track, i.e. Sustainable Buildings, a coherent philosophy must be outlined in the Proposed New Part 11 of the National Building Code, and a clear direction must also be given there to decision-makers, e.g. clients/client organizations, and designers.

Certain essential content must be included in Part 11.  With regard to an improved layout of Part 11, please review the attached  SDI Document: ‘SEED Building Life Cycle’ (PDF File, 55 Kb) .

.

Because you have prioritized ‘real’ building performance over pre-construction design ‘intent’, it is appropriate to begin our comments here …

1.   Sustainability Performance Indicators

In order to prioritize ‘real’ performance, the monitoring of actual sustainability performance in completed and occupied buildings must be comprehensive, accurate and reliable.  Indicators of sustainability performance must, therefore, be included in all sections of the Proposed New Part 11.

Sustainability Performance Indicators provide important signposts for decision-making and design in many ways.  They can translate physical and social science knowledge into manageable units of information which facilitate the decision-making and design processes.  They can help to measure and calibrate progress towards sustainable development goals, and sectoral sustainability targets.  They can provide an early warning to prevent economic, social and environmental damage and harm.  They are also important tools to communicate ideas, thoughts and values because, as statisticians say: “We measure what we value, and value what we measure”.

Performance Indicators may be both quantitative and qualitative … but must cover all stages of the building process, i.e. project feasibility and performance specification, spatial planning, design, construction, management, operation, maintenance and servicing, de-construction, disposal, final site clean-up and sustainable repair.

While many, though not all, types of building performance can be successfully monitored using lightweight portable equipment … a certain number of monitoring devices must also be permanently installed in the building during construction.  A facility to reliably feed the output from these devices back to data collection points, on site and remote, must also be incorporated in the Building’s Intelligent Management System.

Management and collation of sustainability performance data must be reliable.  Uncertainty is always present.  Therefore, Statements of Uncertainty should always be attached to ‘reliable’ data.

Safety Factors should always be included when targeting critical ‘health and safety’ related types of performance.

Sustainability Performance Indicators must be directly comparable across different Global Regions … within Asia, across different countries … and within India, across different States.  A Balanced, Harmonized Core Set of Indian Performance Indicators should be quickly developed.  A Balanced ‘Local’ Set of Performance Indicators will always be necessary.

People tasked with monitoring sustainable building performance must be competent … and independent, i.e. be unconnected to client, design and construction organizations.

Specifically in relation to Energy Performance, the targets to be achieved in new buildings must be far more ambitious.  Please review the attached  SDI Document: ‘SEED Positive Energy Buildings’ (PDF File, 29 Kb) .

.

2.   Properly Defining ‘Sustainable Development’

As currently drafted … Definition 2.26 Sustainable Development, on Page 13 of the Proposed New Part 11, is not only ambiguous, it is inadequate for India’s needs … and it is barely the first half of the full, correct definition …

Sustainable Development  is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.  It contains within it two key concepts:

  • the concept of ‘needs’, in particular the essential needs of the world’s poor, to which overriding priority should be given ;  and
  • the idea of limitations imposed by the state of technology and social organization on the environment’s ability to meet present and future needs.

[ Please refer to the 1987 Report of the World Commission on Environment & Development (WCED): ‘Our Common Future’ – Chapter 2, Paragraph 1.]

This original definition in the 1987 WCED Report IS appropriate for India … and it must become the core definition at the heart of India’s National Sustainable Buildings Strategy !

A careful reading of the full definition makes it clear that there are Many Aspects to this intricate, open, dynamic and still evolving concept … the most important of which are:  Social, Economic, Environmental, Institutional, Political, and Legal.

It is a Fundamental Principle of Sustainability, and one of its Primary Values … that Implementation must be Synchronous, Balanced and Equitable across All Aspects of Sustainability.

The ‘Green Agenda’ merely considers Environmental Aspects of Sustainability … in isolation from all of the other Aspects !   This is a fatal flaw which must be avoided in the Proposed New Part 11 !!

[ I made many references to this issue during the FSAI Conferences in India ! ]

.

3.   Sustainability Impact Assessment (SIA) for India !

Rather than Environmental Impact Assessment … surely the Proposed New Part 11: ‘Approach to Sustainability’ must now use, explain and discuss Sustainability Impact Assessment instead !?!

Sustainability Impact Assessment (SIA)

A continual evaluation and optimization assessment – informing initial decision-making, or design, and shaping activity/product/service realization, useful life and termination, or final disposal – of the interrelated positive and negative social, economic, environmental, institutional, political and legal impacts on the synchronous, balanced and equitable implementation of Sustainable Human & Social Development.

. 

4.   A Robust Legal Foundation for ‘Sustainable Human & Social Development’

Paragraph 4 (Chapter 2, 1987 WCED Report) states …

‘ The satisfaction of human needs and aspirations is the major objective of development.  The essential needs of vast numbers of people in developing countries – for food, clothing, shelter, jobs – are not being met, and beyond their basic needs these people have legitimate aspirations for an improved quality of life.  A world in which poverty and inequity are endemic will always be prone to ecological and other crises.  Sustainable development requires meeting the basic needs of all and extending to all the opportunity to satisfy their aspirations for a better life.’

Trying to list the essential needs of people / the basic needs of all is a very difficult task … but it is work which has been on-going, at international level, since just after the Second World War.

The essential needs of people / the basic needs of all … are specified as being Human Rights and Fundamental Freedoms, and are already fully described within the extensive framework of International Legal Rights Instruments.

Which is why, many years ago, SDI developed this definition for Sustainable Human & Social Development … in order:

  • to give this concept a robust legal foundation ;   and
  • (because of widespread confusion in media, political and academic circles) … to clearly establish that we are talking about sustainable human and social development, and not sustainable economic development, or any other type of development !

Sustainable Human & Social Development

Development which meets the responsible needs, i.e. the Human & Social Rights*, of this generation – without stealing the life and living resources from future generations … especially our children, and their children … and the next five generations of children.

*As defined in the 1948 Universal Declaration of Human Rights.

.

5.   Climate Change Adaptation & Resilient Buildings in India ?

Atmospheric Ozone Depletion and Climate Change are mentioned, here and there, in the Proposed New Part 11.  The important implications of these phenomena for Sustainable Building Design in India are not explained … at all.  Why not ?

To properly respond to these phenomena, both must be integrated into India’s National Sustainability Strategies & Policies.

At the very least … we strongly recommend that Design Guidance on Climate Resilient Buildings be immediately drafted.  This guidance must be appropriate for implementation in each of the different climatic regions of India.

.

6.   A Sustainable Indian Built Environment which is Accessible for All !

Barrier Free is mentioned, here and there, in the Proposed New Part 11.  This is to be warmly welcomed and congratulated.  Under Social Aspects of Sustainable Human & Social Development … this is an essential attribute of a Sustainable Built Environment !   However, no guidance on this subject is given to decision-makers or designers.  Why not ?

However, you should be aware that India ratified the United Nations Convention on the Rights of Persons with Disabilities (UN CRPD) on 1 October 2007.  For your convenience, I have attached copies of the Convention in English, Hindi and Tamil.

You should also be aware that, in December 2011, the International Standards Organization (ISO) published ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’.  In its Introduction, ISO 21542 is directly linked to the U.N. Convention … almost like an umbilical cord.  The scope of this Standard currently covers public buildings.  As the Accessibility Agenda in the U.N. Convention is very broad … much standardization work remains to be finished at international level.

The correct term … Accessibility for All … has been defined in ISO 21542 as including … ‘access to buildings, circulation within buildings and their use, egress from buildings in the normal course of events, and evacuation in the event of an emergency’.

A note at the beginning of the standard also clarifies that Accessibility is an independent activity, i.e. assistance from another person should not be necessary … and that there should be an assurance of individual health, safety and welfare during the course of those (accessibility-related) activities.

In order to fulfil India’s legal obligations as a State Party to the U.N. Convention on the Rights of Persons with Disabilities … adequate Design Guidance on Accessibility must be included in the Proposed New Part 11, supported by ISO 21542.

In addition, the Bureau of Indian Standards (BIS) should immediately adopt ISO 21542 as the Indian National Standard on Accessibility for All … IS / ISO 21542.

[ I made many references to this issue during the FSAI Conferences in India ! ]

.

7.   Fire Safety & Protection for All in Sustainable Indian Buildings ?

Yes … there is 1 mention of ‘fire safety’ and 40 other references to ‘fire’ in the Proposed New Part 11 … but no design guidance.  Why not ?

You should be aware that there is a fundamental conflict between Sustainable Building Design Strategies and the current state-of-the-art in Fire Engineering Design.  As a good 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 engineers 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 Building 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 with the Innovative Building Products and Systems being installed in Sustainable Buildings.

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 ignored, and they remain hidden from everybody’s view.

This must be addressed in the Proposed New Part 11.

U.N. Disability Rights Convention – World Map of States Parties

2013-03-14:   The United Nations Convention on the Rights of Persons with Disabilities (CRPD) was adopted on 13 December 2006 at the U.N. Headquarters Building in New York.  The Convention was opened for signature on 30 March 2007, when there were 82 Signatories to the Convention, 44 Signatories to its Optional Protocol, and 1 Ratification.  Historically, this is the highest number of signatories to a U.N. Convention on its opening day.  It is the first comprehensive Human Rights Treaty of the 21st Century.  It is also the first Human Rights Convention to be open for signature by regional integration organizations, e.g. the European Union (EU).  The Convention entered into force, as an International Legal Instrument, on 3 May 2008.

According to the United Nations … this Convention is intended as a Human Rights Instrument with an explicit social development dimension.  It adopts a broad categorization of persons with disabilities, and reaffirms that all persons with all types of disabilities must enjoy all human rights and fundamental freedoms.  It clarifies and qualifies how all categories of rights apply to persons with disabilities and identifies areas where adaptations have to be made for persons with disabilities to effectively exercise their rights and areas where their rights have been violated, and where protection of rights must be reinforced.

I say … that most of the rights specified in this Convention are already contained in other long-established International Human Rights Instruments, e.g. rights to shelter, free movement, education, employment, voting, etc.  The critical issue for people with activity limitations has always been, and remains to this day … Lack of Accessibility … which prevents them from effectively and independently exercising their basic rights and fundamental freedoms as individual human beings.

Substantively … this is a United Nations Accessibility for All Rights Convention.

.

The World Map below illustrates the situation, in October 2012, with regard to the very large numbers of States Parties to the U.N. Convention on the Rights of Persons with Disabilities (CRPD)

  • 154 Signatories to the Convention ;
  • 90 Signatories to the Optional Protocol ;
  • 124 Ratifications and Accessions to the Convention ;
  • 74 Ratifications and Accessions to the Optional Protocol.

Using the Map, it is simple to identify those ‘other’ countries (nudge-nudge-wink-wink) …

Since October 2012 …

  • Singapore signed the Convention on 30 November 2012
  • Cambodia ratified the Convention on 20 December 2012
  • Albania ratified the Convention on 11 February 2013
  • Barbados ratified the Convention on 27 February 2013

.

HOWEVER … far too many individuals and organizations seem to be content to just settle back and end this good news story at Ratification.  They fail to understand that this is only the beginning !

The real challenge ahead will be to ensure that the Convention is Properly Implemented.

The Target before every State Party is … Effective Accessibility for All !!

‘THE’ Toilet Unit – Aspects of Japan’s Fascinating Culture (II)

2013-03-09:  You may have heard about IT, but you didn’t believe any part of the story.  BUT, here IT is … up close and personal !

Not just a toilet, or a WC … and not just any old toilet unit … this is ‘THE’ Toilet Unit … the ‘all-singing all-dancing wonder of the world’ !   Found throughout Japan … in locations which are private (e.g. residences and hotel rooms), as well as public (e.g. bus and railway stations).

The Toilet Unit in a hotel room shown here, TOTO TCF 521R, is an older model.  Units in public places can have additional functions, e.g. playing music to ‘mask’ noises made by the person on the toilet.  Notice the use of graphics on the control panel, texts in two languages (Japanese and English), separate spray settings for male and female, and a facility to alter spray water pressure and pattern (uniform or oscillating/pulsating).

Afterwards, you might consider visiting the Manufacturer’s WebSite (TOTO, in Japan)http://www.toto.co.jp/ … to examine the advanced technologies driving the development of this product.

But beware of cheap imitations which are beginning to be promoted in Europe !

Mainstream Good Design & Accessibility for All Signage ?

2013-03-06:   Further to an earlier Post, dated 30 November 2012 … on Sustainable Accessibility for All

Accessibility IS a Fundamental Human Right !

‘ For many Weak and Vulnerable People, today’s Complex Human Environment is inaccessible and unsafe … a hostile ‘reality’ which prevents independent functioning and participation in a local community;  it is a blatant denial of their human rights.’

Relevant Human Environment (social – built – virtual – institutional) Factors … factors which are external, or extrinsic, to the context of a person’s life and living situation … include policies and standards, negative attitudes and stigma, lack of services, problems with service delivery, inadequate funding, lack of accessibility in the built environment and to electronic, information and communication technologies, lack of consultation and involvement, and an absence of reliable data and evidence.

Accessibility for All …

Take a really close look at the photograph below … and see a staircase which, in spite of all the legislation in the EU Member States, contravenes almost every accessibility-related design guideline.  It is far from being an unusual scene in our European Built Environment …

Staircase Egress - Unsafe, Difficult Accessibility !!
Photograph taken by CJ Walsh. 2009-10-31. Click to enlarge.

Now, imagine the consequences of one, tiny slip …

Which is why our concern must be with Accessibility for All … which includes consciously thinking about children under the age of 5 years, women in the later stages of pregnancy, and frail older people (not all older people !) … and how they use and interact with their surroundings.

In addition, however … our attention must also turn to the large numbers of people, in all of our societies, with health conditions which result in serious impairments, activity limitations and participation restrictions.  As a prime example, consider the Big-4 Non-Communicable Diseases (NCD’s): Cardiovascular Diseases (e.g. heart attacks and stroke), Cancers, Diabetes, and Chronic Lung Diseases.

These 4 NCD’s – targeted in a World Health Organization (WHO) Global NCD Campaign – share health risk factors (tobacco use, unhealthy diet, lack of physical activity, harmful alcohol use) … cause more than 36 million deaths annually (almost 80 % of deaths, from such diseases, occur in low and middle-income countries) … and result in a high proportion of disability (66.5 % of all years lived with disability in low and middle income countries).

NCD’s can limit one or more of a person’s major life and living activities … such as walking, eating, communicating, and caring-for-oneself.  Examples of common NCD-related impairments include paralysis due to stroke, and amputation as a result of diabetic neuropathy.

When Easily Assimilated Signage IS Essential in Buildings …

Good Architectural Design IS ‘intuitive and obvious’ for building users … design characteristics which are critical in the case of Fire Engineering Design.  However, what is intuitive and obvious in Ireland may not be so intuitive and obvious in Turkey … and what is intuitive and obvious in Europe will certainly not be intuitive and obvious in Africa, India, or China.

Architectural & Fire Engineering Design must, therefore, be adapted to Local conditions … culture, social need, etc., etc.

When a building is NOT ‘intuitive and obvious’ for the broad range of potential building users … easily assimilated signage IS essential …

International Standard ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’ was published in December 2011, as a full standard.  In its Introduction, ISO 21542 is linked to the U.N. Convention on the Rights of Persons with Disabilities (CRPD) … almost like an umbilical cord.

The scope of ISO 21542 covers public buildings.  The Accessibility Agenda in the U.N. Convention is very broad … so much standardization work remains to be completed at international level.

Concerning Accessibility Symbols and Signs … reference should be made to ISO 21542: Clause 41 – Graphical Symbols … and on Pages 106, 107, 108, and 109 … the following will be found:

  • Figure 66 – Accessible Facility or Entrance ;
  • Figure 67 – Sloped or Ramped Access ;
  • Figure 68 – Accessible Toilets (male & female) ;
  • Figure 69 – Accessible Toilets (female) ;
  • Figure 70 – Accessible Toilets (male) ;
  • Figure 71 – Accessible Lift / Elevator ;
  • Figure 72 – Accessible Emergency Exit Route.

I use the word ‘accessibility’, and not ‘access’ … because Accessibility has been defined in ISO 21542 as including … ‘access to buildings, circulation within buildings and their use, egress from buildings in the normal course of events, and evacuation in the event of an emergency’.

A note at the beginning of the standard also clarifies that Accessibility is an independent activity, i.e. assistance should not be necessary … and that there should be an assurance of individual health, safety and welfare during the course of those (accessibility-related) activities.

During the very long gestation of ISO 21542, an overwhelming consensus emerged in favour of using the term Accessibility for All … thereby sidestepping the thorny issue of different design philosophies which are described as being accessibility-related but, in practice, are limited and/or no longer fit-for-purpose.

'Accessibility for All' Symbol ?The Accessibility Symbol used throughout ISO 21542 is shown above.  I know that a small group of people from different countries worked very hard on this particular part of the standard.  My only contribution was in relation to the inclusion of Figure 72, concerning Fire Evacuation.

This ‘accessibility’ symbol is an attractive, modern and, of course, abstract representation of a concept … a person with an activity limitation using a wheelchair.  The symbol succeeds very well in communicating that concept.

However … as an Accessibility for All Symbol … encompassing people with other than functional impairments, e.g. hearing and visual impairments … and children under the age of 5 years, women in the later stages of pregnancy, frail older people … and people with the four main types of non-communicable disease discussed above … is this symbol, also, limited and no longer fit-for-purpose ??

Proposed New Sign for 'Area of Rescue Assistance'

.

Shown next, above, is the proposal for a new Area of Rescue Assistance Sign … which is contained in ISO 7010:2011 / FDAM 115 (2013).  While it is nice to finally see this Safety Sign appear in the mainstream of safety signage … the title being proposed for the sign and the explanatory texts which accompany it are very problematic …

  • The technical term being proposed – Evacuation Temporary Refuge – is too long and too difficult to understand ;
  • The explanatory texts which accompany this Sign are very confusing and misleading.

This problem has arisen because the people who drafted ISO 7010:2011 / FDAM 115 (2013) hadn’t a bull’s notion that ISO 21542 even existed !

In ISO 21542, we use the term Area of Rescue Assistance … which is easy for everybody to understand, including building users, building managers and firefighters, etc., etc.

We also explained, in ISO 21542, that a Place of Safety is a remote distance from the building … not anywhere inside the building !

Mainstreaming Disability …

U.N. CRPD – Preamble

(g)  Emphasizing the importance of mainstreaming disability issues as an integral part of relevant strategies of sustainable development,

As ‘disability’ moves closer towards … and is integrated and fully included in the ‘mainstream’ of sustainable community life and living … it is absolutely imperative that individuals and organizations who make up the Disability Sector become much more cohesive (far less fractious within) … that they begin to fully understand the practices and procedures of the mainstream … and actively and robustly engage with that mainstream.

It is ridiculous, for example, that a large amount of the Sector’s energy is still being diverted into meaningless meditations and endless tracts on whether it is ‘universal design’, or ‘design-for-all’, or ‘inclusive design’, or ‘facilitation design’, etc … when an entirely new design paradigm is being demanded by a world (our small planet when seen from the moon !), which is experiencing enormous levels of human poverty, natural resource shortages, human rights violations, and severe weather events.  The overriding priority must be ‘real’ implementation … Effective Accessibility for All !

Update:  2013-05-31 …

While the wider international design community is working hard on developing an array of Accessibility Symbols to facilitate different health condition and impairment categories, and to suit different environmental situations, e.g. a fire emergency in a building … I recently encountered another interesting contribution …
