Ar C.J. Walsh – Consultant Architect, Fire Engineer & Technical Controller – International Expert on : Sustainability Implementation + Accessibility (including Fire Safety) for All + Sustainable Fire Engineering
2019-07-26: This time last month, in June … I was visiting a hot and humid Hong Kong and Macau, only 1 hour apart on a sea ferry, in China’s Bay Area … to make a Keynote CPD Presentation on Fire Safety for All – Nobody Left Behind ! in the Hong Kong Institute of Architects … and following that up with a full morning Workshop and an afternoon Plenary Presentation at the large 2019 Rehabilitation International Asia-Pacific Region Conference, in Macau, later in the week.
2019 Rehabilitation International Asia-Pacific Conference (Macau) – 26 to 28 June
The Theme of this 3-Day Conference, in #Macau, was Together, Leaving No One Behind, In Disability-Inclusive & Rights-Based Progress. Attended by 1,500 delegates from 30 different countries, the event also gathered together more than 250 international experts, practitioners, academics and researchers from all over the world.
Two Exhibitions, visited by 6,000 people, were organized alongside the Conference: 1) ‘Facilitation and Mobility Aids + Assistive Technologies’ … and 2) ‘Art’.
It is worthwhile noting that #China ratified the U.N. Convention on the Rights of Persons with Disabilities (#CRPD) on 1 August 2008 … but has not yet signed, never mind ratified, the Convention’s Optional Protocol … a clear signal of current political intent which, hopefully, will change in the not-too-distant future. Every year, Hong Kong and Macau submit reports to Beijing regarding CRPD compliance status and implementation.
Without being able to use a #Lift/#Elevator for Fire Evacuation in a building … there is No Fire Safety for All !
In a developing fire incident, People with Activity Limitations must be provided with a safe, alternative evacuation route – just like all other building users – which is a Fundamental Principle of all Fire Engineering. However … just one #User/#Occupant Fire Evacuation Lift/Elevator in a building is an empty, meaningless, Token Gesture !
‘Fire Safety for All’ on Macau TV News … Friday night, 28 June 2019 … my friend and colleague, Ar Joseph Kwan (Architect & Accessibility Consultant based in Hong Kong), is the person being interviewed …
Hong Kong Institute of Architects CPD Seminar – 24 June 2019
Continuing Professional Development (#CPD) is an important aspect of Ethical Architectural Practice. Arriving drenched in a heavy rain downpour on the Monday evening … I was not surprised, therefore, to find that this Seminar was well attended by local architects. Representatives of HK Authorities Having Jurisdiction (#AHJ’s), and Local Fire Services, as well as senior personnel involved in the development of the HK Code of Practice for Fire Safety in Buildings and the HK Barrier Free Design Manual were active participants in the panel discussion afterwards.
‘Fire Safety for All’ on Twitter … @firesafety4all
‘ The creative, person-centred and ethical Fire Engineering response, in resilient built form and smart systems, to the concept of Sustainable Human and Social Development – the many aspects of which must receive balanced and synchronous consideration.’
Organized by FireOx International (Ireland, Italy & Turkey), in joint collaboration with Glasgow Caledonian University’s School of Engineering & Built Environment (Scotland) … and having a widely multi-disciplinary attendance from the U.S.A., Hong Kong SAR (China), Spain, Finland, Scotland, Norway, Germany, England, The Netherlands and Ireland … SFE 2016 DUBLIN was a unique, and very successful, two-day gathering within the International Fire Engineering and Fire Service Communities.
SUSTAINABLE FIRE ENGINEERING fulfils a Critical Role in the realization of a Safe, Resilient and Sustainable Built Environment 4 ALL !
SUSTAINABLE FIRE ENGINEERING facilitates Positive Progress in implementing the United Nation’s 2030 Sustainable Development Agenda, which incorporates 17 Sustainable Development Goals and 169 Performance Targets !
SUSTAINABLE FIRE ENGINEERING fast-tracks Proper Compliance with the 7 Basic Performance Requirements – functional, fully integrated and indivisible – in Annex I of European Union Construction Products Regulation 305/2011 !
A NECESSARY & LONG OVERDUE TRANSFORMATION !
A Building is a permanent construction, complying with basic performance requirements and capable of being easily adapted … comprising structure, essential electronic, information and communication technologies (EICT’s), and fabric (non-structure) … having a minimum life cycle of 100 years … and providing habitable, functional and flexible interior spaces for people to use.
Building Users have a wide and varied range of abilities and behaviours … some having discernible health conditions and/or physical, mental, cognitive, psychological impairments … while others, e.g. young children, women in the later stages of pregnancy and frail older people, are also particularly vulnerable in user-hostile, inaccessible environments. Not everyone will self-identify as having an activity limitation because of the high level of social stigma associated with ‘disability’. Building designers and fire engineers must accept that building users have rights and responsible needs ; the real individual and group fire safety requirements of vulnerable building users must be given proper consideration by both design disciplines, working collaboratively together.
Following the savage 2008 Mumbai Hive Attack in India, and the more recent 2015 and 2016 Attacks in Europe, i.e. Paris, Brussels, Istanbul and Berlin … it is entirely wrong to assume that the main and/or only targets will be specific high-risk buildings types, i.e. Tall/High-Rise, Iconic, Innovative and Critical Function Buildings (refer to 2005 & 2008 NIST WTC 9-11 Recommendations). All buildings and adjoining/adjacent public spaces must be carefully assessed for the risk of direct or collateral involvement in an Extreme Man-Made Event.
It is a fundamental principle of reliable and resilient structural engineering that horizontal and vertical structural members/elements of construction are robustly connected together. All buildings must, therefore, be capable of resisting Disproportionate Damage. The restriction of this requirement, within some jurisdictions, to buildings of more than five storeys in height is purely arbitrary, cannot be substantiated technically … and ethically, must be disregarded.
Fire-Induced Progressive Damage is distinguished from Disproportionate Damage – a related but different structural concept – by the mode of damage initiation, not the final condition of building failure. This phenomenon is poorly understood. But, unless it is impeded, or resisted, by building design … Fire-Induced Progressive Damage will result in Disproportionate Damage … and may lead to a Collapse Level Event (CLE), which is entirely unacceptable to the general population of any community or society. All buildings must, therefore, be capable of resisting Fire-Induced Progressive Damage.
All buildings must also be carefully assessed for the risk of involvement in a Severe Natural Event, e.g. earthquakes, floods, landslides, typhoons and tsunamis.
In all of the above Risk Assessments … the minimum Return Period (also known as Recurrence Interval or Repeat Interval) must never be less than 100 years.
Reacting to surging energy, environmental and planetary capacity pressures … with accelerating climate change … Sustainable Buildings are now presenting society with an innovative and exciting re-interpretation of how a building is designed, constructed and functions … an approach which is leaving the International Fire Engineering and Fire Service Communities far behind in its wake, struggling to keep up.
Passive and Active Fire Protection Measures, together with Building Management Systems (whether human and/or intelligent), are never 100% reliable. Society must depend, therefore, on firefighters to fill this reliability ‘gap’ … and to enter buildings on fire in order to search for remaining or trapped building users. This is in addition to their regular firefighting function. Therefore, there is a strong ethical obligation on building designers, including fire engineers, to properly consider Firefighter Safety … should a fire incident occur at any time during the life cycle of a building.
Structural Serviceability, Fire Resistance Performance and ‘Fire Safety for All’ in a building must, therefore, be related directly to the local Fire Service Support Infrastructure … particularly in developing and the least developed countries. AND … Fire Codes and Standards must always be adapted to a local context !
The fire safety objectives of current Fire Codes and Standards are limited, usually flawed … and will rarely satisfy the real needs of clients/client organizations, or properly protect society. Fire code compliance, in isolation from other aspects of building performance, will involve a consideration of only a fraction of the issues discussed above. There is once again, therefore, a strong ethical obligation on building designers, including fire engineers, to clearly differentiate between the limited fire safety objectives in Fire Codes and Standards … and Project-Specific Fire Engineering Design Objectives … and to explain these differences to a Client/Client Organization. Facility Managers must also explain these differences directly to an Organization’s Senior Management … and directly inform the Organization’s Board of Directors … as appropriate.SFE Mission: To ensure that there is an effective level of Fire Safety for ALL – not just for SOME – in the Built Environment … to dramatically reduce all direct and indirect fire losses in the Human Environment … and to protect the Natural Environment.
To transform Conventional Fire Engineering, as practiced today, into an ethical and fully professional Sustainable Design Discipline which is fit for purpose in the 21st Century … meaning … that fire engineers can participate actively and collaboratively in the sustainable design process, and can respond creatively with sustainable fire engineering design solutions which result in Effective Fire Safety for All in a Safe, Resilient and Sustainable Built Environment.
To bring together today’s disparate sectors within the International Fire Engineering (and Science) Community … to encourage better communication between each, and trans-disciplinary collaboration between all.
To initiate discussion and foster mutual understanding between the International Sustainable Development, Climate Change and Urban Resilience Communities … and the International Fire Engineering and Fire Service Communities.
The realization of a Safe, Inclusive, Resilient & Sustainable Built Environment demands a concerted, collaborative, very creative and widely trans-disciplinary effort at national, local, regional and international levels across the whole planet – Our Common Home. The informed operation of appropriate legislation, administrative procedures, performance monitoring and targeting, and incentives/disincentives, at all of these levels, will facilitate initial progress towards this objective … but not the quantity, quality or speed of progress necessary. Our time is running out !
This Code of Ethics applies … for those who subscribe to its values … to policy and decision makers, and the many different individuals and organizations directly and indirectly involved in the design, engineering, construction, and operation (management and maintenance) of a Safe, Resilient & Sustainable Built Environment for All.
The Purpose of this Code of Ethics is to guide the work of competent individuals and organizations in a context where incomplete or inadequate legislation, administrative procedures and incentives/disincentives exist … but, more importantly, where they do not exist at all … and, amid much confusion and obfuscation of the terms, to ensure that implementation is authentically ‘sustainable’, and reliably ‘safe’ and ‘resilient’ for every person in the receiving community, society or culture … before it is too late !
3. New CIB W14: ‘Fire Safety’ Research Working Group VI Reflection Document: ‘Sustainable Fire Engineering Design, Construction & Operation’, which will establish a framework for the future development of Sustainable Fire Engineering.
Preparation of this Document will soon begin, and the following issues will be explored:
Conceptual Framework for Sustainable Fire Engineering (SFE), with a necessary accompanying Generic SFE Terminology ;
Strategy for Future SFE Development ;
Implementation of 2005 & 2008 NIST WTC 9-11 Recommendations ;
2014-04-21: Notwithstanding the, by now, well-established existence of the United Nations Convention on the Rights of Persons with Disabilities (UN CRPD), International Standard ISO 21542: ‘Building Construction – Accessibility & Usability of the Built Environment’, a host of other national accessibility standards, and a plethora of accessibility design guidance materials … not every ‘real’ site, or building, or built environment, situation is covered. It would be physically impossible.
Unless it is fixed in your mind … or, more importantly, in the ‘group-thinking’ of an organization … that Accessibility-for-All should be, for example, both independent (i.e. it is not necessary for a person to have an assistant) and inclusive (i.e. friends can do things together and no special deal is made about accessibility for one person) … it can be very difficult to emerge from beneath the weight of those documents referred to above … and to apply important disability-related principles flexibly and adaptively in the real world.
At a recent meeting with some teachers in an Irish school (which shall remain nameless) … I advised that a very good and positive start can be made by discussing together and agreeing on a Disability Policy Statement, which will help to guide future actions. More steps are required, of course, but those will come later.
Model Disability Policy Statement for Educational Establishments
Insofar as it relates to the educational activities of
Name of School/College/University/Institute
and its relationships in the wider local community …
We recognise and respect the rights of people with activity limitations:
to lead a fulfilling life – autonomously, independently, and with dignity ;
to integrate into the civil, political, economic, social, cultural and educational mainstream ; and
to participate in the general life of the wider local community on a basis of equal opportunity with everyone else.
Good Education is an Important Key to Social Inclusion
In order to ensure your autonomy and independence, your civil, political, economic, social, cultural and educational integration, and your active participation in the general life of the wider local community – the principle of equal opportunity shall not prevent the adoption or maintenance of services, systems and policies providing for your support or assistance within this establishment.
[ Discussed and Agreed by the School/College/University/Institute Management Board on …… ]
2009-10-08: Deeply interested … and ‘luuuving’ … a hands-on and direct involvement in the Sustainable Restoration of Buildings which are of Historical, Architectural or Cultural Importance … or even those buildings which are not so important … I am deeply frustrated and angry when I look around at what has happened … and continues to happen … in Ireland … horrible, damaging interventions and alterations of all kinds … too many of which cannot be undone.
Certain guru-like organizations and individuals must be robustly challenged !
Yes … in everyday practice, there are pressures concerning an improvement of energy performance (BER Certificates !) … an improvement of accessibility performance for people with activity limitations (2001 WHO ICF) … an improvement of fire safety performance, etc., etc. … and, in the next few short years, adaptation to climate change will require serious attention.
BUT – BUT – BUT … in dealing with these buildings (a priceless heritage for our children, and their children, which cannot be replaced !) … some absolutely core principles must influence the minds of decision-makers in client and construction organizations, national authorities having jurisdiction, regulators … and, most importantly, the minds and souls of architects and engineers. (I am wondering … do engineers have souls ?)
From practical experience, I have found the 16 Principles of the 1964 Venice Charter to be enormously helpful …
ARTICLE 1 The concept of an historic monument embraces not only the single architectural work but also the urban or rural setting in which is found the evidence of a particular civilization, a significant development or an historic event. This applies not only to great works of art but also to more modest works of the past which have acquired cultural significance with the passing of time.
ARTICLE 2 The conservation and restoration of monuments must have recourse to all the sciences and techniques which can contribute to the study and safeguarding of the architectural heritage.
ARTICLE 3 The intention in conserving and restoring monuments is to safeguard them no less as works of art than as historical evidence.
ARTICLE 4 It is essential to the conservation of monuments that they be maintained on a permanent basis.
ARTICLE 5 The conservation of monuments is always facilitated by making use of them for some socially useful purpose. Such use is therefore desirable but it must not change the lay-out or decoration of the building. It is within these limits only that modifications demanded by a change of function should be envisaged and may be permitted.
ARTICLE 6 The conservation of a monument implies preserving a setting which is not out of scale. Wherever the traditional setting exists, it must be kept. No new construction, demolition or modification which would alter the relations of mass and colour must be allowed.
ARTICLE 7 A monument is inseparable from the history to which it bears witness and from the setting in which it occurs. The moving of all or part of a monument cannot be allowed except where the safeguarding of that monument demands it or where it is justified by national or international interest of paramount importance.
ARTICLE 8 Items of sculpture, painting or decoration which form an integral part of a monument may only be removed from it if this is the sole means of ensuring their preservation.
ARTICLE 9 The process of restoration is a highly specialized operation. Its aim is to preserve and reveal the aesthetic and historic value of the monument and is based on respect for original material and authentic documents. It must stop at the point where conjecture begins, and in this case moreover any extra work which is indispensable must be distinct from the architectural composition and must bear a contemporary stamp. The restoration in any case must be preceded and followed by an archaeological and historical study of the monument.
ARTICLE 10 Where traditional techniques prove inadequate, the consolidation of a monument can be achieved by the use of any modem technique for conservation and construction, the efficacy of which has been shown by scientific data and proved by experience.
ARTICLE 11 The valid contributions of all periods to the building of a monument must be respected, since unity of style is not the aim of a restoration. When a building includes the superimposed work of different periods, the revealing of the underlying state can only be justified in exceptional circumstances and when what is removed is of little interest and the material which is brought to light is of great historical, archaeological or aesthetic value, and its state of preservation good enough to justify the action. Evaluation of the importance of the elements involved and the decision as to what may be destroyed cannot rest solely on the individual in charge of the work.
ARTICLE 12 Replacements of missing parts must integrate harmoniously with the whole, but at the same time must be distinguishable from the original so that restoration does not falsify the artistic or historic evidence.
ARTICLE 13 Additions cannot be allowed except in so far as they do not detract from the interesting parts of the building, its traditional setting, the balance of its composition and its relation with its surroundings.
ARTICLE 14 The sites of monuments must be the object of special care in order to safeguard their integrity and ensure that they are cleared and presented in a seemly manner. The work of conservation and restoration carried out in such places should be inspired by the principles set forth in the foregoing articles.
ARTICLE 15 Excavations should be carried out in accordance with scientific standards and the recommendation defining international principles to be applied in the case of archaeological excavation adopted by UNESCO in 1956.
Ruins must be maintained and measures necessary for the permanent conservation and protection of architectural features and of objects discovered must be taken. Furthermore, every means must be taken to facilitate the understanding of the monument and to reveal it without ever distorting its meaning.
All reconstruction work should however be ruled out ‘a priori’. Only anastylosis, that is to say, the reassembling of existing but dismembered parts can be permitted. The material used for integration should always be recognizable and its use should be the least that will ensure the conservation of a monument and the reinstatement of its form.
ARTICLE 16 In all works of preservation, restoration or excavation, there should always be precise documentation in the form of analytical and critical reports, illustrated with drawings and photographs. Every stage of the work of clearing, consolidation, rearrangement and integration, as well as technical and formal features identified during the course of the work, should be included. This record should be placed in the archives of a public institution and made available to research workers. It is recommended that the report should be published.
Note on BER Certificates for Historical Buildings in Ireland
Unless and until that magnificent marketing and public relations firm … Energy Ireland (SEAI) … can openly show that the DEAP Software has been properly modified to handle buildings of historical, architectural or cultural importance … and this modification is fully transparent … Building Energy Rating (BER) Certification for these building types must be put on hold.
Yes, the guidance provided in Technical Guidance Document B (Ireland) is inadequate … and the same can equally be said of Approved Document B (England & Wales).
And yes, you will find only partial answers in British Standard BS 9999, even though it was only published on 31st October 2008 last.
Access Consultants in Ireland and Great Britain rarely deal with any matters relating to fire safety in buildings.
Please allow me, therefore, to fill in some gaps for you.The following guidance is suitable for application in any European country …
People with Activity Limitations (2001 WHO ICF) experience many difficulties when attempting to independently evacuate a fire building.However, our reasoning is very simple.If we can get things right for the most vulnerable building users, we get them right for everyone else also.
The Target Destination … whether evacuation is independent, assisted by other building users or accomplished by means of firefighter rescue … is a ‘Place of Safety’. This term is not well defined in legislation or codes.
Building User ‘Place of Safety’:
Any location beyond a perimeter which is  metres from the fire building or a distance of  times the height of such building, whichever is the greater … and … where necessary and effective medical care and attention can be provided, or organized, within one hour of injury … and … where people can be identified.
Where there is a Risk of Explosion … multiply the numbers in square brackets above by 4 (at least !).
All Fire Evacuation Routes – inside and outside a building – should comply with Accessibility Design Criteria.This is an entirely alien concept to many Fire Prevention Officers in Local Authorities, and Fire Consultants !
Panic Attacks, during evacuation in a ‘real’ fire incident, exist.
Standard Movement Times, during evacuation in a ‘real’ fire incident, do not exist.
People should be able to reach an ‘Area of Rescue Assistance’ inside a building with ease.In practice, few people understand what the word ‘refuge’ means (as in … refuge point, refuge area, area of refuge, etc).As a result, these spaces are regularly misused and/or abused in buildings.And there is great difficulty translating a word into other languages which, in English, can have so many meanings.In Italian fire safety legislation, for example, ‘refuge’ has been translated as ‘spazio calmo’.How crazy is that ?
So … what is an ‘Area of Rescue Assistance’ ?
A building space directly adjoining, and visible from, a main vertical evacuation route – robustly and reliably protected from heat, smoke and flame during and after a fire – where people may temporarily wait with confidence for further information, instructions, and/or rescue assistance, without obstructing or interfering with the evacuation travel of other building users.
This is a notional Area of Rescue Assistance …
A Clear Evacuation Width of 1.5 metres on the Evacuation Staircase facilitates ‘contraflow’ in a fire emergency (shown on the lower flight of stairs), i.e. emergency access by firefighters entering a building and moving towards a fire, while building users are moving away from the fire and evacuating the building … as well as allowing sufficient space to safely carry an occupied wheelchair down the staircase (shown on the upper flight of stairs).
Evacuation Skills & Self-Protection from Fire in Buildings …
A ‘skill’ is the ability of a person – resulting from adequate training and regular practice – to carry out complex, well-organized patterns of behaviour efficiently and adaptively, in order to achieve some end or goal.
Building users should be skilled for evacuation to a ‘place of safety’, and test/drill/non-emergency evacuations should be carried out sufficiently often to equip building users with that skill. Consideration should be given to practicing evacuation once every month or, at most, every two months; once a year is inadequate. In the case of people with a mental or cognitive impairment, there is a particular need to encourage, foster and regularly practice the adaptive thinking which will be necessary during a ‘real’ fire incident.
Since Fire Protection Measures and Human Management Systems are never 100% reliable … it is necessary for frail older people and building users with disabilities to be familiar with necessary guidelines for self-protection in the event of a fire emergency.
Assisted Evacuation & Rescue Techniques …
Firefighters have two functions:
–fighting fires ;and
–rescuing people who are trapped in buildings, or for some reason, cannot independently evacuate a building which is on fire.
People with disabilities are participating more and more, and in ever increasing numbers, in mainstream society.It is necessary, particularly for firefighters, to become skilled in how best to rescue a person with a disability from a building, using procedures and equipment which will not cause further harm or injury to that person.
Manual handling of occupied wheelchairs in a fire evacuation staircase, even with adequate training for everyone directly and indirectly involved, is hazardous for the person in the wheelchair and those people – minimum three – giving assistance.
Generally … Powered Wheelchairs are too heavy for manual handling in any situation.
For these reasons, all lifts/elevators in new buildings should be capable of being used for fire evacuation.Lifts/elevators in existing buildings, when being replaced or undergoing major overhaul, should then be made capable of being used for fire evacuation.
Local Fire Authorities should ensure that they possess the necessary equipment to rescue people with a wide range of impairments, and that specialized rescue equipment is regularly serviced and maintained.Every Fire Authority should have an ‘accessible’ and ‘reliable’ Emergency Call System which is available, at all times, to the public within its functional area.
It is essential that every Firefighter is fully aware of this important public safety issue, and is regularly trained in the necessary rescue procedures involving people with a wide range of impairments.
2009-02-23: The World Business Council for Sustainable Development (WBCSD) has identified buildings as one of the five main users of energy where ‘megatrends’ are needed to transform global energy efficiency in the immediate short term, and so meet the daunting challenge of Climate Change Adaptation.They account for 40% of primary energy (primary energy includes the energy required to generate, transmit and distribute electricity, as well as energy directly consumed on site) in most developed countries, and consumption is rising.
… 2007 WBCSD Energy Efficiency in Buildings (EEB) Project
If you find that you are not responding emotionally to that … please leave your computer immediately and take a cold shower !When you return, check out how far adrift Ireland is – even on paper – in meeting its legally binding 1997 Kyoto Protocol (UNFCCC) responsibilities.After 2012, the European Union’s 2020 Targets will be in a different league altogether.
Let there be do doubt, therefore, that over the next few years … nothing less than a complete cultural shift will be necessary throughout the European Construction Sector – and this very much includes Ireland – beginning with all research and design disciplines and extending right across to any person who works on a construction site or has any part to play in managing, maintaining or servicing a building.
Burden Sharing in the Built Environment
Separate Energy Efficiency Strategies will be required to vastly improve the energy performance of:
–existing buildings … onto which many energy efficiency measures can be successfully grafted … but they will not be cheap, and they will not be 100% effective ;
–buildings of historical, architectural or cultural importance … the integrity of which must be protected ;and
–new buildings, which must therefore carry the major burden.
In addition … if we fully value the Agricultural Industry in Ireland, the burden to be carried by New Buildings may have to be far heavier.
Suggested Building Energy Efficiency Targets in Ireland to 2020
From the Beginning of 2012, i.e. after an Essential Transition Period involving extensive re-education and up-skilling, accompanied by ‘attractive’ incentives …
–Require all New Buildings to achieve a Minimum Building Energy Rating (BER) of ‘A1’ … indicating a Primary Energy Consumption less than or equal to 25 kWh/m2/yr.And require 40% of Primary Energy Consumed to be, directly or indirectly, from Renewable Energy Sources ;
–Require all Existing Buildings to achieve a Minimum Building Energy Rating (BER) of ‘B1’ … indicating a Primary Energy Consumption less than or equal to 100 kWh/m2/yr.And require 15% of Primary Energy Consumed to be, directly or indirectly, from Renewable Energy Sources.Retain Incentive Measures to achieve better performance with regard to energy efficiency and/or renewable energies ;
–Require Buildings of Historical, Architectural or Cultural Importance to achieve a Minimum Building Energy Rating (BER) of ‘C1’ … indicating a Primary Energy Consumption less than or equal to 175 kWh/m2/yr.Retain Incentive Measures to achieve better energy efficiency performance.No legal requirements or incentives with regard to Renewable Energies should apply to Buildings of Historical, Architectural or Cultural Importance.
From the Beginning of 2015 …
–Require all New Buildings to be ‘Positive Energy Buildings’ (see below) ;
–Require all Existing Buildings to achieve a Minimum Building Energy Rating (BER) of ‘A2’ … indicating a Primary Energy Consumption less than or equal to 50 kWh/m2/yr.And require a Positive Energy Contribution of 25 kWh/m2/yr to be from renewable Energy Systems installed in the building ;
–Require Buildings of Historical, Architectural or Cultural Importance to achievea Minimum Building Energy Rating (BER) of ‘B1’ … indicating a Primary Energy Consumption less than or equal to 100 kWh/m2/yr.Retain Incentive Measures to achieve better energy efficiency performance.No legal requirements or incentives with regard to Renewable Energies shall apply to Buildings of Historical, Architectural or Cultural Importance.
‘Effective’ Technical Control of Construction & Post-Occupation Buildings
Any proposed Building Energy Efficiency/Conservation and Renewable Energy Improvements must take place in a legal environment of stringent control during construction (by competent Local Authority Building Controllers and/or Independent Technical Controllers) and rigorous post-construction energy performance monitoring (using Long Wave Infra-Red Thermal Imagery, in conjunction with building roof and external wall Air Seepage Tests).Observation of post-occupation building energy performance will also be necessary.Introduce mandatory 5-Yearly Energy Surveying of Buildings.
The Paradigm for New Buildings – A ‘Positive Energy’ Return
Primary Energy Consumption is less than or equal to 15 kWh/m2/yr.Renewable Energy & Heating Systems then contribute a reliable quantity of energy, per year, which covers the following:
–the Building’s Primary Energy Consumption ;
–an Energy Efficiency Degradation Factor which takes account of the degradation in energy efficiency normally expected during the life cycle of renewable energy and heating systems installed in the building (the rate of degradation will depend on the quality of maintenance and servicing) … and caused by wasteful patterns of building management and/or use ;
–the energy consumed by Private Transport associated with the building ;
–an Energy Return to an Intelligent District or Regional Grid exceeding, by a whole number multiple determined by reference to local conditions, the total energy consumed by the Building (including its Energy Efficiency Degradation Factor) and any associated Private Transport.
Uniquely, this more practical elaboration of the innovative concept of Positive Energy Buildings considers life cycle energy efficiency degradation.
