BER Certificates & New Improvements to French DPE System

Posted by CJ Walsh

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.

New SDI Report on Climate Change Adaptation – Comments ?

Posted by CJ Walsh

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’.

Hazards in Attic Roof Spaces – A Strong Dose of ‘Reality’ !

Posted by CJ Walsh

It’s all happening here !   From trawling the depths of European Union (EU) Legislation in my last Post … to the heights of Attic Roof Spaces in Ireland … what a magnificent contrast !!

This Post has nothing to do with this law, or that law … or the proper technical control of these sorts of troubling situations.  It has everything to do with a strong dose of ‘Reality’ … and the typical sorts of Serious Hazards which lurk quietly, unannounced and generally unheeded in most houses … houses which are occupied by ordinary, average people.

The following photographs could have been taken in almost any house, anywhere in the country !   These particular photographs, however, were taken during a House Inspection for a good friend, somewhere in County Wicklow, during May 2010 …

Harmonized Indicators of Building GHG & Energy Performance

Posted by CJ Walsh

[ BER Certificates (VII) : UNFCCC COP-15 : CIB W108 – Climate Change and the Built Environment ]

2009-12-18:  Even before the gatherings of UNFCCC COP-15 & Kyoto Protocol MOP-5 began … some remarkably positive progress on difficult technical issues had already been made at international level.  Hot off the presses … comes an important document from the United Nations Environment Programme (UNEP) Sustainable Buildings & Construction Initiative (SBCI): ‘Common Carbon Metric’ (December 2009), which was specifically prepared for presentation at Copenhagen.

Leading experts from around the world have developed a standardized method of measuring a building’s carbon footprint … allowing greenhouse gas emissions from buildings anywhere in the world to be consistently assessed and compared.  In the case of existing buildings, improvements can also be measured.

This harmonized method for MRV (Measurable, Reportable & Verifiable) GHG Emissions and Energy Use provides the basis for establishing baselines, performance benchmarking, and monitoring building performance improvements.  These activities are, in turn, fundamental in informing international mechanisms for carbon trading, policy development and analysis, and progress reporting on the mitigation of GHG Emissions from buildings.  Policy and decision makers can produce reports from the data collected through these Metrics/Indicators for jurisdictions, regions, large building stock owners, cities or at a national level to form baselines that can be used to set targets and show improvements in carbon mitigation throughout the building sector.

I am pleased to say that Monsieur Jean-Luc Salagnac (CSTB France), Co-Ordinator of CIB Working Commission 108 : Climate Change and the Built Environment, was directly involved in its development …

Recommendations on Implementing the New Harmonized Approach

All research, design and teaching disciplines involved in the European Building Sector … extending right across to any person who works on a construction site or has any part to play in managing, maintaining, servicing or operating a building … should familiarize himself/herself/themselves with the contents of this document.

As soon as practicable … calculation methods, computer software packages, reports, BER Certificates, etc … and working practices generally … should all be revised and updated to take account of this newly harmonized approach.

Whatever the outcome from Copenhagen in December 2009 … in terms of the presentation of priorities … these should now be switched around … with a strong first emphasis being placed on ‘GHG Emissions’ from Buildings … followed by, and secondly, ‘Energy Consumption’ resulting from the Use/Occupation of Buildings.

What is Measured in the UNEP-SBCI ‘Common Carbon Metric’ ?

While all stages of a building’s life cycle produce GHG Emissions, building use accounts for 80-90% of these emissions … resulting from energy consumed mainly for heating, cooling, ventilation, lighting and electric/electronic appliances.  This, therefore, is the stage of the building’s life cycle that is the focus of the ‘Common Carbon Metric’.

The following Metrics/Indicators shall be used to compile consistent and comparable data:

1.  Energy Intensity = kWh/m2/year (kilo Watt hours per square metre per year)

Scope: Emissions associated with building energy end-use defined in Appendix 1 are included; purchased electricity, purchased ‘coolth'(opposite of warmth)/steam/heat, and/or on-site generated power used to support the building operations.  If available, emissions associated with fugitives and refrigerants used in building operations should be reported separately.

If available, occupancy data should be correlated with the building area to allow Energy Intensity per occupant (o) to be calculated = kWh/o/year.

GHG Emissions are calculated by multiplying the above Energy Intensity times the official GHG emission coefficients, for the year of reporting, for each fuel source used (see Appendix 3).

2.  Carbon Intensity = kgCO2e/m2/year or kgCO2e/o/year (kilograms of carbon dioxide equivalent per square metre or per occupant per year)

Note: GHG conversion factors for each fuel type shall be the same as those used under national reporting for flexible mechanisms for the Kyoto Protocol for the six GHG Gases (see Appendix 4).

Why Buildings ?

The environmental footprint of the Building Sector includes: 40% of energy use, 30% raw materials use, 25% of solid waste, 25% water use, and 12% of land use.  While this new document focuses on the scope of emissions related to energy use of building operations (see Appendix 1), future metrics are required to address these other impacts in addition to social and financial impacts.  At this time the UN’s top priority is climate change … and the building sector is responsible for more than one third of Global GHG Emissions and is, in most countries, the largest emissions source.  While 80-90% of the energy used by the building is consumed during the use (or operational) stage of a building’s life cycle (for heating, cooling, ventilation, lighting, appliances, etc.), the other 10-20% (figure varies according to the life of the building), is consumed during extraction and processing of raw materials, manufacturing of products, construction and de-construction.  Furthermore, significant energy is used in transporting occupants, goods and services to and from the building.

The UNEP-WMO Intergovernmental Panel on Climate Change (IPCC) 4th Assessment Report estimated that building-related GHG Emissions reached 8.6 billion metric tons (t) CO2equivalent (e) in 2004, and could nearly double by 2030, reaching 15.6 billion tCO2e under their high-growth scenario.  The report further concluded that the building sector has the largest potential for reducing GHG Emissions and is relatively independent of the price of carbon reduction (cost per tCO2e) applied.  With proven and commercially available technologies, the energy consumption in both new and existing buildings can be cut by an estimated 30-50% without significantly increasing investment costs.  Energy savings can be achieved through a range of measures including smart design, improved insulation, low-energy appliances, high efficiency ventilation and heating/cooling systems, and conservation behaviour by building occupants.

BER Certificates & ‘Big Brother’ – 1984 Style ? (V)

Posted by CJ Walsh

2009-04-14:  ‘Big Brother’ has arrived on our doorsteps … not in the style of today’s reality television … but in the George Orwell 1984 style of a generation ago … when 1984 used to be far into the distant future.

 

I wasn’t quite sure, but I thought that some readers … avid followers of Ireland’s BER Soap Opera … might be interested in the contents of a certain Important Notice Regarding BER Certificates (on official headed notepaper) … with the name of Mr. Steven Manek MIAVI, Partner, Douglas Newman Good (estate agents) at the bottom of the page … and dated March 2009 … which was circulated to DNG’s client vendors …

 

” We have now been advised by the Irish Auctioneers and Valuers Institute (IAVI) to contact all our vendor clients and advise them that an officer from one of the local authorities has started visiting estate agents’ offices in the greater Dublin area to inspect BER certificates for properties currently for sale/rent.

 

The IAVI have further advised us that if a certificate is not available the inspector is currently allowing a short grace period for provision of a certificate (even though there is no legal reason for them to do so).  If a certificate is not available within that time frame there is a risk of prosecution thereafter as it is a legal requirement to provide a BER certificate.  The maximum fine for a vendor under the legislation is €5,000.

 

In view of this we wish to formally notify you of your legal obligations and recommend that you obtain a BER certificate for your property as soon as possible.

 

The energy rating of a property must be carried out by a trained and registered SEI Building Energy Rating Assessor (BER Assessor).  We have a panel of assessors that can undertake this certification for you and should you wish us to handle this for you please do not hesitate to contact me.”

 

 

Like too many other people … Steven does not seem to have taken the time to read the actual legislation.  Or, maybe he has … which is worse … whatever !

 

The clear intention of this nasty piece of DNG propaganda, however, is to scare the living daylights out of their own client vendors … and to drive them, like lost little sheep into the long spindly arms of their own in-house BER Assessors.

 

 

Hold onto your liathróidí folks !

BER Certificates & Necessary Sectoral Infrastructure (IV)

Posted by CJ Walsh

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 & Poor Indoor Air Quality (III)

Posted by CJ Walsh

2009-02-27:  Energy Labelling of Industrial Products is an essential means of raising consumer awareness about energy efficiency and conservation.  I like being able to wander into an electrical shop anywhere in Ireland, Italy or Turkey, for example … and to compare the energy performance of different makes of washing machines, dishwashers or fridges … and even of apparently similar products in the different countries.

 

I can easily visualize these small industrial products being brought into a test laboratory, and then being put through their paces.  It is a credible system.

 

This is NOT possible, however, with a building.

 

 

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 short document of 7 Pages.  Its Preamble takes up slightly more than the first 2 Pages, and there is a 1 Page Annex at the rear.  Its language is clear and straightforward (see the example of Article 4 below).

 

[What I fail to understand is how and why the Irish National Legislation which implements the Directive … Statutory Instrument No. 666 of 2006: European Communities (Energy Performance of Buildings) Regulations 2006 … is so clumsy, awkward and full of flaws … offering us yet another example of failed ‘light-touch regulation’.  It may also be unconstitutional.]

 

 

 

The EU Directive has something important to say about Indoor Air Quality …

 

Article 4 – Setting of Energy Performance Requirements

 

1. Member States shall take the necessary measures to ensure that minimum energy performance requirements for buildings are set, based on the methodology referred to in Article 3.  When setting requirements, Member States may differentiate between new and existing buildings and different categories of buildings.  These requirements shall take account of general indoor climate conditions, in order to avoid possible negative effects such as inadequate ventilation, as well as local conditions and the designated function and the age of the building.

 

[Quick flashback to a generation ago … the panic, throughout Europe, to conserve energy in the late 1970’s and early 1980’s led to a dramatic reduction in rates and quantities of direct, natural ventilation to the habitable spaces of buildings.  This, in turn, had an adverse impact on Indoor Air Quality, and led to a sharp rise in Asthma among building occupants.]

 

 

 

In Ireland, today, problems concerning Poor Indoor Air Quality continue to occur … typically during the Winter Heating Season.  There is a natural tendency to keep windows closed and to seal permanent ventilation openings.  Accidental indoor air seepage to the exterior is also being reduced in our newer building stock.

 

Poor Indoor Air Quality, an important factor in relation to building related ill-health (also known as ‘sick building syndrome’), can cause serious health impairments and severely restrict a person’s participation in everyday activities, e.g. work.

 

Symptoms and Signs may include:

–         irritation of eyes, nose and throat ;

–         respiratory infections and cough ;

–         voice hoarseness and wheezing ;

–         asthma ;

–         dry mucous membrane and skin ;

–         erythema (reddening or inflammation of the skin) ;

–         lethargy ;

–         mental fatigue and poor concentration ;

–         headache ;

–         stress ;

–         hypersensitivity reactions, i.e. allergies ;

–         nausea and dizziness ;

–         cancers.

 

 

 

The following 2 Performance Indicators of Good Indoor Air Quality, developed with the aim of protecting human health, are recommended:

 

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

 

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

 

 

NOTES:

 

The concept of Protecting Human Health is altogether different from the concept of Assessing Risk to Safety.

 

In Ireland, testing for Radon Activity in buildings must take place during the Heating Season, i.e. the months of November through to March.  What is the use of testing during July, for example, when windows will be wide open ?   Who would even think of doing that ?   I wonder.

 

Measurement Uncertainty of the standard Alpha Particle Etched-Track Detector distributed by the Radiological Protection Institute of Ireland (RPII) is as follows:

–         under laboratory conditions: …………………… in the order of …… +/- 10%

–         under tightly controlled site conditions: …. in the order of …… +/- 20%

–         under typical conditions of use: …………….. well in excess of … +/- 30%

 

Unfortunately, until the RPII includes proper statements of Measurement Uncertainty in its Test Reports … our Organization cannot recommend RPII Radon Testing Services, and we will not accept RPII Test Reports as proper evidence of Radon Test Results.

BER Certificates, Energy Efficiency & Climate Change (II)

Posted by CJ Walsh

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)

Posted by CJ Walsh

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.
