BER Certificates & New Improvements to French DPE System

2011-09-15:  Further to my post, dated  8 June 2009 …

On 13 September 2011 … the French Ministère de l’Écologie, du Développement Durable, des Transports et du Logement announced 6 measures to improve their National DPE (Diagnostic de Performance Energétique) System … equivalent to our BER (Building Energy Rating) System in Ireland.

In the context of my earlier post, you will find these improvements interesting …

Nathalie Kosciusko-Morizet et Benoist Apparu, Secrétaire d’Etat chargé du Logement, ont présenté, Mardi 13 Septembre 2011, 6 Mesures pour Améliorer et Fiabiliser le Diagnostic de Performance Energétique (DPE).  Pour plus de transparence, une amélioration des méthodes de calcul, une meilleure formation des diagnostiqueurs et un contrôle plus efficace de la profession.

Rendu obligatoire depuis le 1er Janvier 2011 par le Grenelle Environnement, le  Diagnostic de Performance Energétique (DPE)  est amené à jouer un rôle de plus en plus important dans les décisions d’acquisition ou de location de logements.

Un Outil Apprécié des Français

La Performance Energétique des Bâtiments représente un double enjeu: elle permet d’améliorer le pouvoir d’achat des Français par une meilleure maitrise des dépenses d’énergie, et par ailleurs, elle participe à la lutte contre le changement climatique.

[ Aujourd’hui, le secteur du bâtiment représente 42.5 % des dépenses d’énergie.  Il est le plus gros consommateur d’énergie en France parmi l’ensemble des secteurs économiques. ]

Désormais connu du grand public, le dispositif bénéficie d’une image positive auprès des Français puisqu’en Mars 2011, 80% des ménages considèrent la consommation énergétique du logement comme un critère de choix très important, et 60% déclarent que s’ils étaient appelés à mettre leur appartement en vente, ils envisageraient de faire des travaux pour en améliorer la performance énergétique.

« Le DPE a été très rapidement adopté par les Français et est devenu un critère essentiel pour guider leur choix d’acquisition et location de logement.  Il était donc important d’en faire un outil dans lequel ils ont une entière confiance.  Les mesures qui vont être mises en place ont pour but de faire de l’étiquette énergétique un outil de référence incontestable, permettant aux Français d’améliorer leur pouvoir d’achat en évaluant et en maitrisant mieux leur consommation d’énergie » ont souligné les Ministres.

6 Mesures pour une Etiquette Energétique Fiabilisée

Ce programme s’axe autour de 6 mesures portant sur plus de transparence, une amélioration des méthodes de calcul, une meilleure formation des diagnostiqueurs ou encore un contrôle plus efficace de la profession.

     1. Une Meilleure Transparence vis-à-vis des Particuliers:  Le diagnostiqueur devra à présent expliciter les données qu’il renseigne auprès du particulier à travers un relevé détaillé.  Cela permettra au particulier d’être entièrement informé sur la façon dont a été réalisé son document.  La remise d’un document officiel limitera également le risque de DPE ‘frauduleux’.

     2. Amélioration de la Méthode de Calcul:  Pour un résultat plus fiable, il s’agit d’augmenter le nombre de données à analyser afin de faire un calcul plus précis de la performance énergétique.

     3. Utilisation de Logiciels Validés par le Ministère:  Pour un meilleur encadrement des logiciels utilisés, il s’agit de limiter la liste de logiciels autorisés à générer des DPE aux logiciels ayant été soumis à une procédure d’évaluation menée entre 2008 et 2010 par le ministère et l’Agence de l’Environnement et de la Maîtrise de l’Energie (ADEME).

     4. Une Base de Données des DPE sera Mise en Ligne:  Les statistiques permettront, entre autre, de nourrir l’élaboration des stratégies nationales et locales.

     5. Une Montée en Compétence des Diagnostiqueurs, en augmentant le niveau de difficulté des examens.  Jusqu’à aujourd’hui, un seul examen existait, à présent 2 niveaux de difficulté seront mis en place selon la mention (mention « bâtiments d’habitation » ou « tous types de bâtiments » – tertiaires, publics, privés, etc.).

     6. Un Contrôle plus Efficace, avec pour les particuliers, un annuaire des diagnostiqueurs mis en ligne par le ministère, et la mise en place d’une enquête de la Direction Générale de la Concurrence, de la Consommation et de la Répression des Fraudes (DGCCRF) dans le secteur du diagnostic immobilier dans le cadre de sa mission de protection économique du consommateur …

L’ensemble de ces mesures, qui entreront en vigueur dès le 1er Janvier 2012, permettront l’amélioration d’un outil encore récent, mais dont l’utilité et l’efficacité sont déjà démontrées.

Climate Change ?#$#? … 2007 SDI Letter to John Gormley !

2011-01-29:  Some people say that a week is a long time in politics … but, here in Ireland, during the last two weeks … every single day feels like a year !   To the uninformed outside observer, this may have all the appearance of being an elaborate circus … but, we like our politics to be complex, interesting and very frothy.

Briefly … the Irish Green Party has recently removed itself, awkwardly, from the Ruling Coalition Government in this country … and the Green Party Agenda has gone up in smoke … definitely a Climate Changing Greenhouse Gas !   Mr. John Gormley T.D., Leader of the Green Party, has therefore resigned as Minister for the Environment, Heritage & Local Government … and his Green Party departmental colleague, Mr. Ciarán Cuffe T.D., Minister of State with special responsibility for Sustainable Transport, Horticulture, Planning and Heritage at the Departments of the Environment, Transport and Agriculture has also resigned.

With all of Ireland’s current economic woes … this decision by the Green Party has ensured that ‘Climate Change’ is fast dropping off the list of national priorities.

However, as a result of these political shenanigans … the word ‘Green’ has received a severe hammering and will induce a nasty taste in the mouths of many Irish Voters during the next few weeks which lead up to a General Election.  To be honest, I heartily cheer this development … since ‘GREEN’-ness, i.e. a sole and blinkered consideration for the Environmental Aspects of Sustainability is a ‘pre-version’ (fans of the film: ‘Dr. Strangelove’ will understand what I mean) of Sustainable Human & Social Development.  It is also a peculiar quirk of ‘greens’ that they love the environment … but hate people !

As a prelude to what I will say about the proposed enabling legislation for climate change action in Ireland … the 2010 Climate Change Response Bill … I thought that it would be interesting to reveal the contents of a submission I made to Mr. John Gormley back in late 2007.  Concerning his reaction … I wondered how it was possible for anybody to write such a long letter in reply, and say nothing.

.

Mr. John Gormley T.D.,                                                                                           2007-12-18.

Minister for the Environment, Heritage & Local Government,

Department of the Environment, Heritage & Local Government (DEHLG),

Custom House – Dublin 1.

Re:  Your Meeting with IIEA on Friday, 7th December 2007

Dear Minister,

At the Meeting with the Institute of International & European Affairs (IIEA), in North Great George’s Street, I raised two points directly with you:

     i)   The Great Difference between ‘Real’ Building Energy Performance and Claimed ‘Theoretical’ Performance.   In a context where the mandatory use of long wave infra-red thermal imagery will not be introduced in the Revised Technical Guidance Document L of the Building Regulations, due to be issued shortly, and there will continue to be No Effective System of Building Control anywhere in the country … no relationship exists between Claimed ‘Theoretical’ Performance and ‘Real’ Performance, such is the poor quality of construction on Irish Building Sites.  The Energy Numbers which continue to be produced by Sustainable Energy Ireland are – almost – pure fantasy.

     ii)  Sourcing of Climate Change Research & Models for Necessary Institutional Reform Must Extend Beyond Britain.   The following is taken from the Irish National Climate Change Strategy 2007-2012 (page 45) …

‘ Ireland has also engaged in an exchange of information on impacts and adaptation activities through the British-Irish Council. This initiative has focused on exchanging data on research projects which have improved the understanding of climate change impacts at a local level.’

I suggested to you that if this were, actually, to be the approach to Research in Ireland … we will be in serious trouble.  Furthermore, far too many people in important organizations (including the IIEA) are only looking across the water for Models of Necessary Institutional Reform.  We must also, in Ireland, look to the rest of Europe and Japan to find the Best Research and the Most Effective Institutional Models.

Please see the enclosed World Business Council for Sustainable Development (WBCSD) Summary Report: ‘Energy Efficiency in Buildings – Business Realities & Opportunities’ (October 2007), which was presented at an important Paris Conference at the beginning of November, 2007.

This Report looks at what can be achieved in Europe and many other parts of the world – today – using currently available building technologies and systems … IF ‘real’ implementation is taken seriously.  Barriers to progress and costs have also been examined.

In the final analysis, however, a properly resourced Indigenous Research Capability, focused on Irish Conditions and Needs, is vitally necessary to drive ‘Real’ Performance and Innovation in this country.

.

Post-Bali Leadership from Ireland (and DEHLG !)

A Kyoto II Instrument will be agreed and ratified before the end of 2012.  The 1997 UNFCCC Kyoto Protocol must now be seen, therefore, as just the beginning of a long-term process which will last until the end of the century.  Some Necessary Direction and a large pinch of Ethical Leadership are urgently required to properly re-position Ireland in this Process.

The following Post-Bali Target Scenario for Ireland is presented for your consideration:

  • Ireland should set 1990 as the Benchmark/Base Year for All Kyoto Greenhouse Gases ;
  • Statements of Measurement and Calculation Uncertainty should be fully transparent (nationally, and at EU level), and made at every stage of Ireland’s Kyoto Compliance ;
  • The EU’s Objective of a 30% Reduction in Greenhouse Gases by 2020, compared to 1990, is the Relevant Short Term Target (refer to Paragraph 31 of the German Presidency Conclusions from the E.U. Council’s Brussels Summit on 8th and 9th March 2007) ;
  • As our ‘Real’ Performance, under Kyoto I, continues to be so weak and disingenuous … we should not expect to receive as generous an intra-EU burden sharing arrangement as before.  Instead, Ireland should adopt the 2020 National Target of a similar 30% Reduction in Greenhouse Gases, compared to 1990 ;
  • Our Contingency Target for 2020 should be a 33% Reduction in Greenhouse Gases, compared to 1990.  When considering ‘real’ performance in any field of human endeavour, it is usual to include a safety factor in any calculations …. in this case, 3% ;
  • Ireland’s Recourse to the Use of Carbon Sinks and Kyoto Mechanisms in meeting the 2020 Contingency Target should be restricted to 1/4 of ‘Real’ Performance …
    • ‘Real’ Performance (no sinks/mechanisms) – minimum 24% Reduction in Greenhouse Gases by 2020, compared to 1990 ;
    • Use of Carbon Sinks and Kyoto Mechanisms – 9% Reduction in Greenhouse Gases by 2020, compared to 1990 (this figure includes the contingency 3%) ;   and
    • As the Construction Sector (when properly identified) should share more of the national burden than, for example, Agriculture …. its Target should be a 40% Reduction in Greenhouse Gases by 2020, compared to 1990.  Remember the range of reductions which were initially proposed at Bali …. 25-40% ?
  • Part 1 of SDI’s Submission for the Irish Construction Sector (IIEA Climate Change Project, Sectors Sub-Group – June 2007) stressed the great need to properly restore the Construction Sector’s Infrastructure.  Otherwise, this Sector will not be able, in reality, to reach any Energy Performance Targets … low or high.  Of course, what will eventually appear on paper, or as a computer print-out, is an entirely different matter !

However, having been able to access information about the recent WBCSD Research Project, and using it as a valid substantiation … it then became possible to deal with the issue of Energy Performance Targets for All Buildings (new, existing and those of historical, architectural and cultural importance) more aggressively.

Enclosed, please also find Part 2 of SDI’s Submission for the Construction Sector (IIEA Climate Change Project, Sectors Sub-Group – November 2007).

.

Ireland’s Climate Change Strategy ?

     1.  Ireland’s Current ‘Real’ Situation with Regard to Kyoto (I) Compliance should be clearly understood by the Irish Public.  Using the recently issued European Environment Agency (EEA) Report 5/2007: ‘Greenhouse Gas Emission Trends & Projections in Europe 2007 – Tracking Progress Towards Kyoto Targets’, we have extracted just a few snippets of interesting information (enclosed) …

  • Instead of 1990, Ireland has chosen 1995 as the Base Year for HFC’s, PFC’s & SF6 ;
  • Ireland’s Per Capita greenhouse gas emissions are nearly the worst in the EU-27 ;
  • Ireland’s Per GDP greenhouse gas emissions are far too high ;
  • Ireland’s ‘Real’ Distance-To-Target (no sinks/mechanisms) is very bad.

Ireland is still grimly grasping on to a ‘Business as Usual’ Approach.  This is actually being reinforced by the relevant Institutions of the State, who insist on merely Playing with Numbers … and then publishing Cosmetic Public Relations Brochures for consumption in Ireland and, unfortunately, on the wider European and International Stages.

     2.  The following National Policy/Strategy Documents & Legislation should directly relate to one other, and their implementation should be tightly co-ordinated …

  • National Sustainable Development Strategy ;
  • National Climate Change Strategy ;
  • National Climate Change Adaptation Strategy ;
  • National Spatial Strategy ;
  • National Development Plan ;
  • National Public Procurement Law.

Not only have some of the above not yet even been drafted, but others are unacceptably inadequate, outdated and/or fundamentally flawed.  And the synergies which would normally accrue from co-ordinated implementation are being lost.

     3.  The World Business Council for Sustainable Development 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.

Nothing less than a Complete Cultural Shift will be necessary throughout this Sector, 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.

Yet, Irish Construction is not presented as a Coherent Sector anywhere in National or European Greenhouse Gas Databases.

Separate Strategies are urgently required to greatly improve the energy performance of:

  • Existing Buildings … onto which many energy efficiency measures can be successfully grafted, but they will not be cheap ;
  • Buildings of Historical, Architectural or Cultural Importance … the integrity of which must be protected ;   and
  • New Buildings, which must therefore carry the major burden.

     4.  Raising the (General) Awareness of Irish Society regarding Climate Change and Mobilizing People and Organizations for (Effective) Action are two entirely different concepts.  Which concept is informing Strategy Development within the DEHLG ?

A €15 m. Marketing Campaign, spread over 4-5 Years and including the ‘Change’ WebSite (!?!?), will not mobilize anyone … to do anything.

     5.  Your proposals concerning Necessary Building Energy Efficiency Improvements to be included in the Revised Technical Guidance Document L are inadequate.  Part L should be applicable to ALL New Buildings.

It has also been insufficiently emphasized in public discussions/consultations concerning this issue that any proposed Building Energy Efficiency Improvements must take place in a context of stringent control during construction (by a sufficient number of 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 external fabric air seepage tests).  Follow-up observation of post-occupation building energy performance will also be required.

This is the one – and only – means of …

  • tweaking Computer Software Tools so as to produce more realistic outputs ;   and
  • obtaining reliable construction-related energy performance data and statistics.

Please Note Well:  Without suitable references to the use of long wave infra-red thermal imagery (essential, if working at ambient temperatures – short wave, if working at high temperatures) in Section 5, the Revised TGD L will be absolutely meaningless !!

Because of wasteful patterns of building management and/or use – even in the most energy efficient building – we would also stress that far more attention should be paid to the concept of Intelligent Energy Efficiency Management.

     6.  We strongly urge you, in accordance with the 2007 Bali Action Plan, to rapidly advance development of the National Climate Change Adaptation Strategy, and to ensure that it is properly implemented.

     7.  We call for the creation of an adequately resourced Sustainable Development Commission with the necessary legal mandate, independence and technical expertise to monitor – in an integrated, continual and proactive manner – Ireland’s mitigation and adaptation performance in relation to the adverse effects of climate change.  We also call for a New Social Partnership for Sustainable Development & Climate Change Adaptation.  Addressing Climate Change must be considered an integral element of Sustainable Development Policies.

.

At Sustainable Design International … we continue to find, in everyday practice, that the most challenging barriers to Policy Implementation are Institutional – lack of proper horizontal policy integration in Public Authorities, and antiquated approaches to management in Private Organizations.  At every level, the concept of Sustainable Human & Social Development is poorly understood.

Should you have any questions or comments, please contact me at your convenience.

Yours sincerely,

C.J. Walsh,  etc., etc.

New SDI Report on Climate Change Adaptation – Comments ?

This is the HomePage of my Technical Blog … but on a separate WebPage (see the toolbar above), I have been slowly building content, with links to related sources of information, on the subject of a CIB Working Commission 108 International Climate Change Project, which is about to enter its final important stage.

When published in the spring/early summer of next year … 2011 … the CIB W108 Report: ‘Sustainable Climate Change Adaptation in the Built Environment’ will comprise 2 Parts:

           I  – International Synthesis on Sustainable Climate Change Adaptation.

          II  – National Perspectives on Sustainable Climate Change Adaptation.

.

Today, 18 November 2010 … I uploaded onto that separate WebPage the National Report for ‘IRELAND’, which will appear in Part II of the CIB Publication.  I am the person who drafted this report … and it has not been an easy task !   You will see that much attention is paid to institutional and implementation issues.

I now invite comments on the National Report … any comments … from those with a particular interest in the subject … and from the general public.

Comments should arrive here no later than Monday, 20th December 2010 … pretty please !

.

Before commenting upon the National Report, however, it would be useful if you also took a glance at the following three relevant documents …

  • Ireland’s 5th National Communication (NC5) under the 1992 United Nations Framework Convention on Climate Change, dated 3 March 2010 ;
  • UNFCCC In-Depth Review of Ireland’s 5th National Communication (NC5), dated 2 November 2010 ;
  • EU WHITE PAPER – Adapting to Climate Change: Towards a European Framework for Action … European Commission Communication COM(2009) 147 final, dated 1 April 2009.

.

2009 EU White Paper – ‘Introduction’ (Page 3, first three paragraphs)

Climate change increases land and sea temperatures and alters precipitation quantity and patterns, resulting in the increase of global average sea level, risks of coastal erosion and an expected increase in the severity of weather-related natural disasters.  Changing water levels, temperatures and flow will in turn affect food supply, health, industry, and transport and ecosystem integrity.  Climate change will lead to significant economic and social impacts with some regions and sectors likely to bear greater adverse affects.  Certain sections of society (older people, people with activity limitations, low-income households) are also expected to suffer more.

Addressing climate change requires two types of response.  Firstly, and importantly, we must reduce our greenhouse gas emissions (GHG), i.e. take mitigation action … and secondly, we must take adaptation action to deal with the unavoidable impacts.  The EU’s recently agreed climate change legislation puts in place the concrete measures to reach the EU’s commitment to reduce emissions to 20% below 1990 levels by 2020 and is capable of being amended to deliver a 30% reduction if agreed as part of an international agreement in which other developed countries agree to comparable reductions and appropriate contributions by economically more advanced developing countries based on their responsibilities and capabilities.  However, even if the world succeeds in limiting and then reducing GHG emissions, our planet will take time to recover from the greenhouse gases already in the atmosphere.  Thus, we will be faced with the impact of climate change for at least the next 50 years.  We need therefore to take measures to adapt.

Adaptation is already taking place but in a piecemeal manner.  A more strategic approach is needed to ensure that timely and effective adaptation measures are taken, ensuring coherency across different sectors and levels of governance.

.

2009 EU White Paper – The Proposed EU Framework: Objectives & Action (Page 7, #3)

The Objective of the EU’s Adaptation Framework is to improve the EU’s resilience to deal with the impact of climate change.  The framework will respect the principle of subsidiarity and support overarching EU objectives on sustainable development.

The EU’s framework adopts a phased approach.  The intention is that phase 1 (2009-2012) will lay the groundwork for preparing a comprehensive EU Adaptation Strategy to be implemented during phase 2, commencing in 2013.

Phase 1 (2009-2012) will focus on four pillars of action:

1)    building a solid knowledge base on the impact and consequences of climate change for the EU ;

2)    integrating adaptation into EU key policy areas ;

3)    employing a combination of policy instruments (market-based instruments, guidelines, public-private partnerships) to ensure effective delivery of adaptation ;    and

4)    stepping up international co-operation on adaptation.

For phase 1 to be a success … the EU, national, regional and local authorities must co-operate closely.

The proposals set out in this paper cover actions to be taken in the first phase and are without prejudice to the future structure of the EU budget and to the current and future multi-annual financial framework.

.

IRELAND – Part II National Report for CIB W108 Climate Change Project

In the spring of 2007, the Department of Environment, Heritage & Local Government (DEHLG) – Ireland’s statutory Authority Having Jurisdiction (AHJ) – published the ‘National Climate Change Strategy 2007-2012’.  This document can be accessed and downloaded at … http://www.environ.ie/en/Environment/Atmosphere/ClimateChange/   It is of concern to note, however, that ‘Climate Change’ related content is not easy to find on this WebSite !   Comprehensive Enabling Climate Change Legislation, which this Department, and the Irish Government, initially promised for Easter 2010 … and then June 2010 … has, at the time of writing (mid-November 2010), still not made an appearance in the Dáil (Ireland’s Parliament) !

The Department of Environment, Heritage & Local Government (DEHLG) lacks strong and competent political direction and the institutional capacity to effectively co-ordinate and oversee the implementation of National Climate Action.  For this reason, closer scrutiny of its activities will be required from the Dáil Committee System.

Contrary to current practice … Foreign Development Aid should not be used to obtain any sort of domestic or in-country credit for Ireland’s National Climate Change Strategy !

Specifically concerning Climate Change Adaptation … the following is stated on Page 45 of the 2007-2012 National Climate Change Strategy Document …

‘As part of a comprehensive policy position on climate change, the Government is committed to developing a national adaptation strategy over the next two years.  This strategy will provide a framework for the integration of adaptation issues into decision-making at national and local level.’

The DEHLG does not, however, intend to publish a National Climate Change Adaptation Strategy until 2013 (Ireland’s NC5).

.

Climate Change Action in Ireland – Summary

Ireland’s Climate Action to date, i.e. effective Climate Change Mitigation and Adaptation Implementation, has been laboriously slow and lethargic.  It may best be characterized as ‘Business as Usual’, combined with some ‘Cosmetic Tinkering at the Edges’ as the need arises … the universal excuse, almost a mantra, being that “the competitiveness of the national economy must not be impaired”.  National Performance has been guided by an official policy of exploiting to the maximum all of the UNFCCC Kyoto Protocol’s Flexibility Mechanisms while, at the same time, showing a stark indifference to Climate Adaptation … an over-reliance on Marketing Campaigns in the public media as opposed to mandatory implementation on the ground … and a preference for ‘Soft’ Performance Estimation on paper/computer monitor rather than the more painful ‘real’ performance calculation, which would generate reliable data and statistics to be managed by Ireland’s Central Statistics Office, in co-ordination with EuroStat in Luxembourg.

Despite the importance of the Construction Sector in Ireland and Europe … and its very large adverse impacts on regional and local climate … a significant barrier to concerted Sectoral Climate Action exists because ‘construction’ is not yet identified as a separate Sector, by either the Environmental Protection Agency (Ireland) or the European Environment Agency (Copenhagen) … in National and European Greenhouse Gas (GHG) Emission Databases.  Furthermore, our systems of governance and institutional organization, at both levels, do not appear to have the capacity … either to understand or to manage an effective response to the climate challenges created by the Sector.

Climate Change Mitigation Efforts are failing in Ireland; the current economic downturn merely camouflages that unpalatable fact.  Therefore, the necessary corrective actions described in this National Report fall under the heading of ‘Climate Change Adaptation’.

BER Certificates – A Major Infra-Red Survey in Paris (VIII)

2009-12-19:  Still recovering from the shock of the 2009 Copenhagen Accord (!!!) … something has to be said before talking about Paris or France again.  It’s funny looking back, now, to last November …

Wednesday Evening (2009-11-18) – Soccer World Cup Play-Off – Ireland v France – Stade de France 

I admit it … I was not a believer before the match … and was expecting that Ireland would be blown out of the stadium.  However … at the kick-off, I found myself glued to the television.  It was a blatant, intentional and obvious handball by Thierry Henry.  There might be a simple explanation … perhaps, he is a fan of Gaelic Football and somebody gave him a present of a DVD last Christmas !

Après le Match en Irlande 

There is nothing so boring as listening to the English go on … and on … and on … and on … about that 1986 Diego Maradona Goal.  Pay-back time for Las Malvinas ?   In Ireland, let’s stop the whinging … and move on.  We can be a great team – not just a good team – at the next European Championships in 2012 !

Anyway … back to Paris

Early last spring (2009) … as a Special Project in preparation for Copenhagen … some very intelligent people in the Office of the City Mayor (who understand the value, but also the limitations, of marketing campaigns !) … organized that 500 typical buildings of the city, from each of the different historical periods up to the present day, would be surveyed using Infra-Red Thermography.  To complement the building surveys … an aerial survey of the whole city was also carried out.  The results will be placed in the public domain … for all in Paris to see … during 2010.

The following Project Description was contained in the French Design e-Newsletter ‘Maison à Part’ (www.maisonapart.com), dated Friday 23rd October 2009.  This description is more interesting and informative than a similar description on the City Mayor’s WebSite (www.paris.fr) !

Mais d’où viennent ces photos ?   “La nuit du vendredi 6 mars 2009, l’ensemble du territoire parisien a été thermographié depuis un avion” est-il expliqué.  “La thermographie aérienne est une technique qui permet de mesurer la température à la surface des toitures à l’aide d’une caméra infrarouge et d’analyser la déperdition de chaleur des constructions.”   Ainsi, “plus le toit apparaît rouge, plus il est chaud, ce qui signifie qu’une partie de l’énergie dépensée pour chauffer le logement est en fait perdue dans l’atmosphère.”  Une campagne de prises de vue des façades à l’aide d’une caméra thermique – l’hiver en début de soirée, lorsque le thermomètre est en dessous de 5°C – réalisée par la ville permet de compléter l’ensemble.

“Chaque grande période de construction à Paris est analysée sous l’angle architectural et thermique, avec des préconisations de travaux pour chacune” précise les organisateurs de l’exposition.

BER Certificates – A Proposal for What’s Next ! (VI)

2009-06-08:  The other day, I received an impassioned e-mail … an extract …

 

” We are an energy rating company involved in a campaign for enforcement.  Yesterday, we made a presentation to SEI (see attached).  It was the result of a 2-month attempt to meet with the DEHLG and SEI.  You are right in your article about them ‘not WANTING to know’.

 

My only question is: do you have any ideas on what’s next ? ”

 

 

 

The BER Gold Rush Soap Opera so far …

 

There are thousands of BER Assessors out there around the country … each having paid a ‘pretty penny’ for training, for exams, and for registration … and work on the ground is very scarce.  A significant number of those Assessors have an inadequate understanding of building construction … while some of the people who are involved in providing Validated BER Training Courses are, to put it mildly, similarly unendowed.

 

Energy Ireland (SEI) is the Issuing Authority, but it has absolutely no experience as a Control Authority.  And has anyone bothered to read the relevant Legal Disclaimer on the SEI WebSite ?   It does, however, have a large marketing budget … those smarmy, wall-to-wall radio advertisements, which refer to the ‘property game’, continue to irritate my sensitive ear drums !

 

Apparently … 20% of BER Assessments are turning out to be faulty, i.e. they have not been properly carried out by Registered BER Assessors.  In other words, 1 out of every 5 BER Certificates needs to be thrown in the paper recycling bin.  Furthermore … I have discussed in one of my first posts how there is only a very tenuous relationship between a BER Certificate and the ‘real’ energy performance of a specific building.  And in relation to ‘real’ buildings … there is a general non-compliance rate of 70% on Irish Building Sites with the minimal energy performance requirements in Part L of the Irish Building Regulations.

 

SEI’s Register of BER Assessors is unreliable.

 

What a magnificent waste of time, energy and money !

 

 

 

Some Comments on a Recent BER Certificate … 

 

Sitting on the desk to the left of my computer keyboard is a recent Building Energy Rating (BER) Certificate and its accompanying Advisory Report … issued sometime during the second half of May 2009 … for a private, single-occupation dwelling house somewhere in Leinster … and using the DEAP Version 3.0.0 computer software.  I do not wish to identify the specific Certificate.

 

This particular BER Certificate Documentation comprises:

 

         the actual BER Certificate ;

 

Can I be sure that the correct choices were made with regard to the software input information/data ?   No.

 

         its accompanying BER Advisory Report.

 

Not missing any marketing trick, and in stark contrast to the actual BER Certificate … there is an Energy Ireland (SEI) Logo at the top of the first page of the Advisory Report … and an elaborate footer with SEI contact information on the last page.

 

Meanwhile, there is not one single mention of Statutory Instrument No. 666 of 2006: European Communities (Energy Performance of Buildings) Regulations 2006 anywhere in the Report … nothing to explain that SEI is the Issuing Authority for the purposes of this national legislation … or that there is such a thing as a BER Register … etc, etc, etc.

 

The Advisory Information provided in the Report is too vague to be useable … and there are silly typographical errors.

 

Did the BER Assessor request any information from the owner about the house ?   It is impossible to tell whether he/she made any such request.

 

Am I assured that the BER Assessor had an adequate understanding of building construction ?   Definitely not.

 

[ Specific comments about other issues might identify the actual BER Certificate. ]

 

 

 

What’s Next ?

 

The following remarks are directed at those BER Assessors, building owners, landlords, building professionals and general punters who do wish to spend their money on something worthwhile … something which has meaning, and is useful.

 

Energy Labelling of Buildings, just as in the case of other energy using/consuming industrial products … is positive and very worthwhile.

 

The legal basis established by European Union (EU) Directive 2002/91/EC of the European Parliament and of the Council, of 16 December 2002, on the Energy Performance of Buildings … is a good start.

 

I would much prefer if this Directive were linked in more directly to the Extensive Framework of the Construction Product Directive … EU Council Directive 89/106/EEC, of 21 December 1988, on the Approximation of Laws, Regulations and Administrative Provisions of the Member States relating to Construction Products.  The reason that this has not already happened is because of a startling lack of horizontal integration between the different Directorates-General in the European Commission.

 

If there are problems with how the BER Legislation is operating at national level in Ireland, it is not the fault of Brussels or Directive 2002/91/EC … it is our problem … and it is up to us to remedy the situation.

 

There are 3 Immediate Priorities for Building Energy Rating in Ireland:

 

         increase accuracy ;

         reduce uncertainty ;

         improve reliability.

 

 

 

An Initial Proposal

 

Without amending any legislation … and without reference to the Department of the Environment, Heritage & Local Government (DEHLG), Energy Ireland (SEI) and the Construction Industry Federation (CIF) … none of which have shown any proper leadership in relation to these issues, but seem interested only in playing games …

 

 

1.  The BER Certificate

 

Attach a Single-Page Appendix to the actual BER Certificate which clearly shows the Input Information/Data selected by the Registered BER Assessor.  Include a Statement of Measurement/Calculation Uncertainty concerning the Energy Rating Process … and a Statement of Competence in Building Construction, with the Assessor’s Signature … at the bottom of the page.

 

Show the Page Number on the Certificate as Page No.1 of 2 … and on the Appendix as Page No.2 of 2.

 

A BER Certificate should not be valid without this Appendix.

 

 

2.  The Accompanying BER Advisory Report

 

Generally … tighten up the information provided in the Report, make it easier to understand … and make it more useable !   DO NOT TIE energy performance, or any other aspects of building performance, to the minimal – ‘abysmal’ – performance targets described in the guidance texts of Technical Guidance Documents A-M in the Irish Building Regulations.  We have to aim much, much higher !!   The European Union’s 2020 Climate Change Targets will be heavy going for Ireland, even if there is no agreement in Copenhagen at the end of 2009.  And … insert Page Numbers !!!

 

Include Additional Components in the BER Advisory Report:

 

         Findings of a Formal Interview/Questionnaire Survey with the building owner, landlord or manager – some questions should have an open format ;

         Results of Infra-Red Thermography and Air Seepage Testing – discussed at length in previous posts ;

         Results of a Radon Test – as already discussed, an important indicator of Indoor Air Quality and whether or not there is adequate Ventilation in the building.

BER Certificates & Necessary Sectoral Infrastructure (IV)

2009-03-14:  The Construction Sector Comedy of Errors continues without intermission …

 

On Tuesday last, 2009-03-10, I attended a Conference in Dublin Castle: ‘Energy Efficiency in Historic(al) Buildings’, organized by the Department of the Environment, Heritage & Local Government (DEHLG) and the Irish Georgian Society.  Boys and girls … we are in trouble … flat, uninspiring presentations from our beloved DEHLG policy makers.  Missing … any wider context of required energy efficiency targets across the whole of the built environment … or views and solutions from anywhere else beyond our two little islands (Ireland & GB) on the periphery of Europe.  The approach taken to this important subject was “let’s just jump in, and see what we can do”.  What a day !

 

[Note: Thanks also to the DEHLG … Ireland still has no National Climate Change Adaptation Policy.]

 

That same morning, on Tuesday, an Opinion Piece: ‘Research Hub Benefits All’ appeared in The Irish Times (page 13), written by no other than Mr. Kieran McGowan, Chairperson of CRH.  He was full of suggestions about research in Ireland, and was most happy to support the proposed research alliance between University College Dublin (UCD) and Trinity College Dublin (TCD).  However, a quick visit to the CRH Holding Company WebSite is both relevant and informative.  There, you will learn that the Company operates in 35 countries, employing approximately 93,500 people.  Entering the key words/phrases … ‘research’, ‘construction research’, and even ‘building research’ … into the site search engine yields nothing of value … that’s right … nichts, nada, niente, zilch, zero !   With all the window dressing about Corporate Social Responsibility (CSR), etc, etc … the principal ‘value’ in CRH still remains short term ‘shareholder value’.  If it looks interesting, gobble it up.  Why waste money on a Research Division ? … which should be located in Ireland !

 

 

Yesterday, 2009-03-13, another Article appeared in The Irish Times (bottom of page 5): ‘Ireland Closer to Kyoto Emissions Target Due to Economic Slump’, by Mr. Harry McGee, IT Political Staff (?).  The Environmental Protection Agency (EPA) Press Release which generated this newspaper article was released on Wednesday, 2009-03-12, at 17.59 hrs. in the evening.

 

The 19-Page EPA Report: ‘Ireland’s Greenhouse Gas Emission Projections 2008-2020’ was issued on the same day as the newspaper article – 2009-03-13.  Excellent media management !

 

These three different texts fail to examine, or even discuss, the following issues …

 

         How many € Millions and € Millions belonging to the Irish Tax Payer are being spent, and will be spent into the far future, on buying this country out of trouble … because of the abject failure to meet our responsibilities under Kyoto I (up to 2012), and the Real EU 2020 Target of -30% GHG Emissions on 1990 levels (assuming there will be an agreement in Copenhagen, next December, on a Post-2012 Kyoto II Instrument).  This has always been the EU Target.  See Paragraph 31, German Presidency Conclusions of the Brussels European Council (8 & 9th March 2007).

 

         Having seen the numbers and range of assumptions which underpin the EPA’s GHG Emission Projections up to 2020 … how Reliable are those projections ?   Where are the critical Statements of Uncertainty ?

 

         Who are the Individuals who sat on their fat, over-paid asses throughout the last 10-15-20 years, and allowed this country to fall into such a haphazard state ?   Would any of these individuals be the same people who are now preaching sermons on ‘responsible’ GHG Emission Compliance … and still foisting upon us Voluntary Codes of Practice and Compliance Schemes, Ineffectual National Marketing Campaigns, Feather Light Regulation, and Press Releases which obscure what is really happening ?

 

Do you see any parallels with current events in the Irish Financial Sector ?

 

         Can the Irish Construction Sector be expected to meet any Real Performance Targets (e.g. Proper Building Energy Rating Labelling, Meaningful GHG Emission Reductions, Serious Energy Efficiency Improvements, whatever … ) – as distinct from Theoretical Performance on paper – without a Very Necessary Sectoral Infrastructure capable of shaping suitable responses to those targets, and ensuring that they are implemented ?

 

 

 

As already discussed in an earlier Post … a Complete Cultural Shift in the Irish Construction Sector is essential.  So, let me give you a small flavour of what we need to do …

 

 

1.  Construction Data & Statistics:

 

Ireland does not currently possess a comprehensive National Construction Database.  No reliable statistics can be presented with regard to building or construction-related performance in 1990, or 2005.  No coherent projections, therefore, can be made for the years 2010, 2012, 2020 or 2050 … under any futures scenario.

 

The Central Statistics Office (CSO) gathers construction-related Economic Data.  Energy Ireland (SEI) Databases are not reliable.

 

Construction is not identified as a separate Sector, by either the Environmental Protection Agency (Ireland) or the European Environment Agency (Denmark), in European Greenhouse Gas Emission (GHG) Databases.

 

 

 

2.  A Concerted Programme of Infrastructure Restoration:

 

         Re-establish and adequately resource an Independent National Institute for Spatial Planning & Construction Research (formerly known as An Foras Forbartha) in Ireland, having joint responsibility with the CSO for maintaining a reliable National Construction Database.

 

Construction Research & Innovation must be given a high national priority !   

 

The National Institute must establish close working relationships with the relevant European Union Institutions, particularly EuroStat in Luxembourg.

 

[By ‘independent’ … I mean at a long, long, long arm’s distance away from the Department of the Environment, Heritage & Local Government (DEHLG).]

 

         Re-establish and adequately resource an Independent and Fully Accredited National Construction Testing & Development Complex.

 

         Re-Format, Revise & Horizontally Integrate the National Building Regulations.

 

The existing format is both limited and seriously flawed.  For discussion in a later Post.

 

         Adequately resource the Irish National Accreditation Board (NAB), and closely monitor the quality of its work.

 

         Adequately resource the National Standards Authority of Ireland (NSAI) and ensure that Ireland participates vigorously in the European Standards Organizations and ISO (International Standards Organization).

 

         Adequately resource an Independent Irish Agrément Board (IAB), and closely monitor the quality of its work.

 

[By ‘independent’ … I mean at a long arm’s distance away from the National Standards Authority of Ireland (NSAI).  These two organizations were supposed to have been separated a few years ago anyway.]

 

         Adequately resource awareness raising and Institutional Capacity building for Sustainability and Climate Change Adaptation in the Department of the Environment, Heritage & Local Government (DEHLG), Energy Ireland (SEI) and the Construction Industry Federation (CIF).

 

         Adequately resource awareness raising, Re-Training and Re-Education for Sustainability and Climate Change Adaptation at all levels in the rest of the Construction Sector, including All (Professional) Design Disciplines and All Construction Organizations.

 

 

 

3.  Initial Construction Quality:

 

Post-completion repairs and/or system retrofitting always involve compromises, are costly and are rarely anywhere near being 100% effective.  Ensure Proper Initial Construction Performance through robust inspection of buildings during construction … checking that all relevant legislation has been complied with and that construction products have been approved, i.e. properly shown to be ‘fit for their intended use (in the location of use)’, etc.

 

         Adequately resource, with Staff (e.g. building controllers, inspectors, administrative, legal), Monitoring Equipment (e.g. sound meters, long wave infra-red cameras, etc.) and Technical Support (e.g. training, library facilities, access to research) … all Building Control Authorities in the country.

 

Introduce a fully Integrated (including Part B of the Building Regulations) and Mandatory Inspection Scheme on all Construction Projects, at the following Construction Stages …

 

Foundations ;

Drainage ;

Ground Floor Construction ;

Super-Structure (above Radon Resisting Membrane) … inspections to take place at a level no higher than first floor ;

Roof.

 

Such an Inspection Scheme must operate uniformly across the country.  Piecemeal variations and maverick procedures operated by National Authorities Having Jurisdiction (AHJ’s) or Individual Local Authorities cannot any longer be tolerated.

 

 

 

4.  Consumer Protection:

 

         Establish an Independent and Comprehensive National Building Insurance Scheme.

 

Self-Regulation by the Architectural and Legal Professions offers merely the ‘appearance’ of protection to the Irish Consumer.

 

The current system of Royal Institute of the Architects of Ireland (RIAI) / Law Society ‘Opinions on Compliance with Building Regulations’ is inadequate … and offers no protection to the Irish Consumer.  The phrase ‘substantial compliance’ is much misunderstood and widely abused.

 

         Introduce and adequately resource the discipline of Independent Technical Controller.  He/she must be independent from Construction-related Organizations, the Building Design and Legal Professions … Local Authorities … and any other National Authorities Having Jurisdiction (AHJ’s).

 

         Introduce a Mandatory Building Completion Certification System.

 

Before any Building can be occupied, a Certificate of Building Completion Performance, and an Accompanying Report, must be issued by an Independent Technical Controller.  The System will include an independent evaluation of compliance with relevant building legislation and a thorough examination of ‘real’ construction performance.

 

Building Completion Documentation can be designed to include …

         a Fire Safety Certificate, which is issued only after adequate monitoring of the actual fire safety related construction ;

         a Disability Access Certificate, which is issued only after adequate monitoring of the actual access related construction ;

         a Building Energy Rating (BER) Label ;

         a Sustainability Impact Assessment (SIA) ;

         etc., etc.

 

 

 

[Many of the above ideas have been incorporated in the 2008 Institute of International & European Affairs (IIEA) Publication: The Climate Change Challenge, which presents a strategic overview of Irish Climate Change Policy.]

BER Certificates, Energy Efficiency & Climate Change (II)

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 achieve  a 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.

BER Certificates, Legislation & Thermal Comfort (I)

2009-02-20:  The recent comment submitted by Mr. Robin Evans regarding the use of Infra-Red Thermography as an aid to BER Assessment … and the high level of confusion and misinformation in the marketplace, which I have now had an opportunity to examine more closely … have forced me to conclude that a series of posts on BER Certificates would be good for the system – ‘my’ system !

 

There are many pieces in this jig-saw puzzle, but the final picture is wonderful … please believe me.

 

 

Before I start to assemble anything, however, a few small details …

 

         Infra-Red Thermography.  This is a valuable technical aid during any Energy Survey of any Building.  It is remarkable how much information can be gathered by a good, high-resolution Infra-Red Camera.  But, it must be used competently …  Because we are working in ambient temperature conditions, i.e. between -10OC and +30 OC, it should be a Long Wave Infra-Red Camera (≈ 8-12 microns).  The temperature difference between the inside of the building and the exterior should be at least 10 degrees C … it would be better with 15 degrees C.  The Camera Operator should be fully familiar with the operation of the Camera and its associated computer software, etc … and he/she should know what they are looking at.  In other words, some sort of architectural background is essential … not only are images taken outside the building, but they are also taken inside the building !   Any Camera Work should be done after dark.  It is not necessary to do a midnight to 4 o’clock in the morning shift … 8 o’clock in the evening until midnight is perfectly fine.  By the way, none of this work can be done in just 30 minutes.  Finally, Infra-Red Work is best carried out, in Ireland, during the Heating Season, i.e. the months of November through to March.  Depending on the year, it may be possible to squeeze in the end of October and the beginning of April.

 

In the old days, I used to work as part of a Multi-Disciplinary Team of 4 People (not all males !), comprising a Civil Engineer, a Physicist/Expert in Measurement, an Engineering Technician with a background in Social Science, and myself as Architect/Fire Engineer/Technical Controller.  They were great days !

 

 

Robin … in order to provide this service for the owner of a typical suburban, semi-detached house … €100 (Euros) is a little on the low side, even as a ‘lost leader’.

 

And … the Irish Public are indeed blissfully unaware of the efficacy of Infra-Red Thermography.  The ‘powers that be’ in Ireland, i.e. the Department of the Environment, Heritage & Local Government (DEHLG), Energy Ireland (SEI) and the Construction Industry Federation (CIF), are not at all interested in the ‘real’ energy performance of buildings.  They have a vested interest in not being interested.  Suddenly … the image of an ostrich, with head deeply embedded in sand, floods my mind …

 
Colour Clip Art Image of an Ostrich, with head deeply embedded in sand. Meanwhile, in the background, an hourglass signals that time is running out !

Colour Clip Art Image of an Ostrich, with head deeply embedded in sand. Meanwhile, in the background, an hourglass signals that time is running out !

  

         BER Certificates & EU/National Legislation.  Mr. Charlie McCreevy, Ireland’s EU Commissioner, during one of his many ‘direct, pragmatic and neo-liberal’ talks in Dublin, used the following magnificent phrase in relation to the national implementation of European Union Legislation in the different EU Member States … ‘National Gold Plating and Divergent Implementation’ … some important words to remember !   However, I learned this valuable lesson myself a long, long time ago.

 

Irish National Legislation:  Statutory Instrument No. 666 of 2006: European Communities (Energy Performance of Buildings) Regulations 2006.

 

These Regulations may be unconstitutional.  A prime example … Section 23 (1) states that a person authorised by Energy Ireland (SEI) under the Regulations … ‘may enter, inspect and examine a building or any part of a building for the purpose of forming an opinion as to whether or not a BER Data File or BER Certificate issued for the building, or part of the building, is warranted’.  In relation to a private, single-occupation dwelling house … this provision is entirely unacceptable !

 

The Register of BER Assessors on the SEI WebSite is not reliable.

 

Because of ‘national gold plating and divergent implementation’ in Ireland, it is necessary to be familiar, also, with the originating EU Secondary Legislation.

 

European Union Legislation:  EU Directive 2002/91/EC of the European Parliament and of the Council, of 16 December 2002, on the Energy Performance of Buildings.

 

Both pieces of legislation can be downloaded from the SDI WebSite … here.

 

 

         Thermal Comfort in Buildings.  The starting point for any discussion about this subject should be an International Standard, which is also the European Standard and the Irish National Standard … ISO 7730  Moderate Thermal Environments – Determination of the PMV and PPD Indices and Specification of the Conditions for Thermal Comfort.

 

This Standard establishes the following important general principle … and is also critical in relation to people with activity limitations who use/occupy/visit buildings: Man’s/Woman’s Thermal Sensation is mainly related to the thermal balance of his/her body as a whole.  This balance is influenced by his/her physical activity and clothing, as well as the environmental parameters: air temperature, mean radiant temperature, air velocity (i.e. draughts) and air humidity.

 

Air Temperature, alone, is definitely not an Indicator of Thermal Comfort in a building.

 

 

         Technical Control of Construction.  The 2005 & 2008 NIST Reports on the 9-11 WTC Incident have presented us with some stark language … ‘NIST urges state and local agencies to rigorously enforce building codes and standards since such enforcement is critical to ensure the expected level of safety … unless they are complied with, the best codes and standards cannot protect occupants, emergency responders, or buildings.’

 

With regard to Private Construction in Ireland … Building Control Authorities in Ireland are, purposefully, not sufficiently resourced to be ‘effective’.  See my earlier Post, dated 2009-02-12.

 

With regard to Public Construction in Ireland … self-regulation is no regulation !  Government Departments, the Office of Public Works and Local Authorities can, far too often, be complacent, careless and/or stubborn concerning compliance with even the minimal performance levels specified in building regulations, codes and standards.

Building Energy Rating (BER) Certificates – Worried ?

2008-12-12:  Thursday, 1 January 2009, is fast approaching, and any person offering an existing house for sale or rent around this time is being bombarded by all sorts of ‘marketing blurbs’ in the different media about having to produce a BER Certificate.

 

Don’t be worried.

 

When in doubt, go directly to the actual legislation … and in this case, it is Statutory Instrument No.666 of 2006: European Communities (Energy Performance of Buildings) Regulations 2006.

 

Legislation cannot be retrospective … so, if a house has already been offered for sale or rent before 1 January 2009, no BER Certificate is required.

 

 

BER Certificate Ireland

Colour image of an Irish BER Certificate. See S.I. No.666 of 2006: European Communities (Energy Performance of Buildings) Regulations. Click to enlarge.

 

And … if you care to look at the text on one of these ‘certificates’ (in the top right-hand corner), you will notice the following …

 

” The Building Energy Rating (BER) is an indication of the energy performance of this dwelling.”

 

However, unless long wave infra-red thermography has been used under proper conditions, by a competent person, as part of a comprehensive energy survey of the house … and thermal images were taken … and other accurate and precise information was gathered about the actual energy performance of this specific house … the statement in the BER Certificate is misleading.

 

There is only a very tenuous relationship between a BER Certificate and the ‘real’ energy performance of a specific building.

 

What’s more …. Energy Ireland (SEI) knows full well that this is the case.

 

 

In addition, as if that were not bad enough …. Energy Ireland (SEI) have been sitting on a Report for approximately 3 years which indicates that there is a general non-compliance rate of 70% (that’s right folks !) with the minimal – some might say “abysmal” – energy performance requirements, which apply to new houses, in Part L of the Irish Building Regulations.

 

And …. because everybody can see that our national system of building/technical control in Ireland is entirely inadequate, that figure of 70% non-compliance may be an underestimate.

 

Many, many months ago, I asked for a copy of this SEI Report.

 

I am still waiting.
