Energy Performance of Buildings

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

Posted by CJ Walsh

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.

Carbon Monoxide (CO) Protection in Building Habitable Spaces

Posted by CJ Walsh

2011-01-13:  Carbon Monoxide (CO) is an odourless, colourless and toxic gas.  Because it is impossible to see, taste or smell the toxic fumes, CO can kill you before you are aware it is in your home.  At lower levels of exposure, CO causes mild harmful effects which are often mistaken for the flu (influenza).  These symptoms include headaches, dizziness, disorientation, nausea and fatigue.  The effects of CO Exposure can vary greatly from person to person depending on age, overall health and the concentration and length of exposure.  Source: Environmental Protection Agency (EPA), USA.

Recent tragic deaths from CO Poisoning have occurred in Ireland … not only in the home, but also in a hotel.

Sources of Carbon Monoxide (CO) … unvented kerosene and gas space heaters; leaking chimneys and furnaces; back-drafting from furnaces, gas water heaters, wood stoves, and fireplaces; gas stoves; generators and other gasoline powered equipment; automobile exhaust from attached garages; and tobacco smoke.  Incomplete oxidation during combustion in gas ranges and unvented gas or kerosene heaters may cause high concentrations of CO in indoor air.  Worn or poorly adjusted and maintained combustion devices (e.g., boilers, furnaces) can be significant sources, or if the flue is improperly sized, blocked, disconnected, or is leaking.  Car, truck, or bus exhaust from attached garages, nearby roads, or parking areas can also be a source.  Source: EPA, USA.

 

If there is a fuel burning / heat-producing appliance in any habitable space, in any building … and if you have not done so already … you must do something NOW to check that you are protected effectively from CO Poisoning.  Shift your ass !

In order to improve energy conservation and efficiency in buildings … direct, natural ventilation from the exterior is still being actively discouraged … and buildings are becoming more tightly sealed, during construction or major refurbishment, to prevent unintended air seepage.  Generally, this has been causing a serious increase in Building Related Ill-Health (also known as ‘Sick Building Syndrome’) … much of which is still going un-reported.

.

BRIEF CHECKLIST – IMMEDIATE ATTENTION

1.  Check that there is sufficient, clear, direct natural ventilation in any habitable space which contains a fuel burning / heat-producing appliance.  Next … Check that the terminal unit / outlet of the flue coming from that appliance is not blocked.  Then … Check the route of any flue from the appliance.  If, for example, a flue passes through another habitable space … that space must also be properly ventilated.

2.  Check that all fuel burning / heat-producing appliances are ‘fit for their intended use’ (this must be shown !), are working properly … and that they are regularly serviced by people who are competent to do so.  Paperwork is not a reliable indicator of competence !   Remember the problems with FÁS !?!

3.  Do not confuse Carbon Monoxide Detectors with Smoke Detectors !   Only install a dedicated Carbon Monoxide (CO) Detector for the task of detecting Carbon Monoxide.  And … that Detector must be shown to be ‘fit for its intended use’.  Read the writing on the outside of the box carefully … and then read all of the instructions inside the box !

.

With regard to the issue of Carbon Monoxide (CO) Poisoning in Ireland … Statistics Gathering is not reliable.  National Legislation concerning the installation of Carbon Monoxide Detectors in buildings should have been introduced many years ago … but this has not yet happened.  Furthermore … don’t hold your breath waiting for this much-needed legislation.  Based on past performance, technical and administrative officials in our relevant authority having jurisdiction, i.e. the Department of Environment, Heritage & Local Government (DEHLG), will prefer to wait before acting until similar legislation is introduced in Britain (England & Wales).

.

I will just describe what I have done in my own house … in the kitchen …

[Smoke Detectors are separately linked into a monitored security and fire warning system.]

In every room where a fuel burning / heat-producing appliance is located … a Carbon Monoxide (CO) Detector is installed.  In the kitchen, for example, the Detector is fixed on the wall … at about head height, when sitting down at a table (appropriate for the normal pattern of use there) … and at a distance of approximately 2 metres from the natural gas kitchen range.  Control of direct, natural ventilation to the appliance is active … meaning, it always receives attention.  The usual kitchen clutter, e.g. clothes ‘waiting’ for ironing, etc., is never allowed to cover or block the Detector.  Everybody in the house understands the purpose of this product.

.

About the performance of the Carbon Monoxide (CO) Detector in the event of a ‘real’ CO Leakage … I am comfortably assured, as I have known the EI Company in Shannon since the mid-1980’s.  At that time, I was the first architect in Ireland to install smoke detectors in any local authority housing scheme … and EI gave great technical back up and support, for which I am still very grateful.  I might add that those same smoke detectors were installed against the wishes of the local fire department.  A report on the whole test installation process was later presented, by Dr. M. Byrne, Engineering Manager of EI, to an International Fire Conference in Dublin.

The particular Carbon Monoxide (CO) Detector shown in the photograph above is a battery-operated Model Ei206D.  There are no heavy, smoke sealed fire-resisting doorsets in the house … so the sound level of the distinct alarm / warning signal [85 dB(A) minimum at 3 metres] is more than adequate.  A few years ago, this was an expensive item to buy !   Now, however, CO Detectors are widely available … and at a more reasonable price.

Very Importantly … Ei Electronics have also developed a range of products – Solutions for All – which are suitable for use by People with Activity Limitations … http://www.eielectronics.com/ei-electronics/special-needs

.

Harmful Health Effects Associated with Carbon Monoxide (CO) Inhalation … at low concentrations: fatigue in healthy people and chest pain in people with heart disease.  At higher concentrations: impaired vision and co-ordination; headaches; dizziness; confusion; nausea.  Can cause flu-like symptoms which clear up after leaving home.  Fatal at very high concentrations.  Acute effects are due to the formation of Carboxyhaemoglobin (COHb) in the blood, which inhibits oxygen intake.  At moderate concentrations: angina, impaired vision, and reduced brain function may result.  At higher concentrations: CO Exposure can be fatal.  Source: EPA, USA.

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 …

There are simple Design and Construction Solutions to all of these problems … and Competent, Independent Technical Control over the works being carried out is absolutely essential.

BUT … Dysfunctional Government Departments and State Agencies are still … to this day … directly sponsoring and knowingly contributing to these hazardous situations in our homes !

2009 Camberwell Fire – Today’s Fire Engineering Challenges

Posted by CJ Walsh

In Ireland, it is rarely the case that there is an opportunity to practice Rational, Evidence-Based Fire Engineering … and to apply its Principles in a manner which is both professional and project-specific.  The grim reality of everyday fire consultancy revolves around playing ‘cat and mouse’ with current national building and fire regulations/codes … with ‘cost effectiveness’, i.e. to achieve a defined objective at the lowest cost, or to achieve the greatest benefit at a given cost … being the real, hidden driver behind such dangerous games !   Who wants to hear that the Irish Fire Safety Certification System is little more than a charade … an elaborate, resource consuming paper exercise … made all the more meaningless because Part B: ‘Fire Safety’ (of the Second Schedule to the 1997 Building Regulations, as amended) is isolated from a necessary and vital consideration of the other Parts, particularly Parts A: ‘Structure’; D: ‘Materials & Workmanship’; K: ‘Stairways, Ladders, Ramps & Guards’; and M: ‘Access for People with Disabilities’ ?

The fire was caused by a faulty television set, and resulted in the loss of 6 lives, with 15 residents and 1 firefighter left injured. London Fire Brigade was required to assist the evacuation of a further 40 building occupants to safety. Along with the serious loss of life, and the large number of injured people ... over 90 families had to vacate their flats.

Discussing the Principles of Fire Engineering … and elaborating on the significant differences between the limited Fire Safety Objectives of legal regulations/codes … and the much broader range of Fire Engineering Design Objectives intended to fully protect social wellbeing and the interests of clients/client organizations, i.e. to properly protect their asses and their assets, in the event of a fire … is a constant, tortuous, but rewarding, struggle.  Masochism does help !

However, the 2009 Fire in a High-Rise Flat Complex at Camberwell, London (GB) … from just looking at the photograph above and reading available information about the spread of fire internally … raises some challenging fire engineering issues for building designers, property managers and construction organizations.

. 

1.  Reliability of People Strategies in a Fire Emergency ?

In spite of the People Strategies elaborated in current Fire Codes/Regulations/Standards … it is totally and utterly irresponsible to advise people to wait in their own flats/apartments during a fire incident, or to develop fire safety strategies based on this approach … unless the confidence level (of ‘Competent Persons’ in Control … managers, designers and builders … of the flat/apartment complex) with regard to the following aspects of construction is very high …

  • reliability of both passive and active fire protection measures ;
  • reliability of fire compartmentation (see below) ;
  • reliability of not just the building’s structural stability, but also its serviceability, during the fire and for a minimum period of time afterwards, i.e. the ‘cooling’ phase.

Competent Person:  A person capable of making sound value judgements in the area of professional  endeavour in which he/she possesses profound knowledge, understanding and practical experience.

Fire Codes/Regulations/Standards, wherever or whatever their origin, are NOT Infallible … and it is unbelievably mind-boggling, and sad, to witness a blind and unquestioning faith in such documents !

Looking beyond the headline figure of 6 Fatalities in the 2009 Camberwell Fire … adequate attention should also be focused on the 16 Injured … comprising building occupants and firefighters … the lengthy disruption of community wellbeing resulting from the fire … 90 Families had to be re-located … and, of course, the tremendous amount of direct and indirect damage to property and the environment.  And, I wonder … how did the more vulnerable occupants … and there may also have been visitors present in the complex at the time … cope in this emergency situation ?

This is why Fire Safety, Protection and Evacuation for All must be a Priority on any ‘Sustainability’ Agenda. 

.

2.  Independent Technical Control of AHJ Construction ?

I have said this before, but it is worth repeating here again … Self-Regulation Is No Regulation !   Surely this lesson has been burnt into our souls, following the recent scandals, financial and otherwise, in Ireland ?   National and Local Authorities Having Jurisdiction (AHJ’s) … Government Departments & Agencies, Semi-State Organizations, a myriad of Qwangos, the Office of Public Works and Local Authorities are complacent, careless and stubborn concerning proper compliance with even the minimal performance requirements specified in fire regulations, codes and standards.

The 2005 & 2008 National Institute of Standards & Technology (USA) Reports on the 9-11 WTC Incident in New York presented us with some stark language … and a set of important Recommendations which must be heeded …

‘ NIST recommends that such entities be encouraged to provide a level of safety that equals or exceeds the level of safety that would be provided by strict compliance with the code requirements of an appropriate governmental jurisdiction.

To gain broad public confidence … NIST further recommends that as-designed and as-built safety be certified by a qualified third party, independent of the building owner(s).  The process should not use self-approval for code enforcement in areas including interpretation of code provisions, design approval, product acceptance, certification of the final construction, and post-occupancy inspections over the life of the buildings.’

[2005 NIST Final Report on WTC 1 & 2 Collapses – Recommendation No. 25]

Later posts, here, will examine the individual NIST Recommendations in more detail.

However … many individuals and organizations, with vested interests, are still trying to discredit and/or ignore the Recommendations contained in the 2005 & 2008 NIST Reports on the WTC 9-11 Incident.   British Standard BS 9999:2008 is a typical case in point … a document which is slowly seeping into the marrow of the Irish Fire Establishment.  The complete and abject failure to consider any of the NIST Recommendations during the long development of this British Standard, or even to reference the Reports in the Standard’s Bibliography … was an inexcusable and unforgivable technical oversight.  The result was … and remains … a sloppy, crassly inadequate, deeply flawed and discriminatory national fire safety standard.  The British Public deserves far better !

At this stage … reluctantly … I must invite the Chair of British Standards Institution Committee FSH/14, Mr. David B. Smith, to seriously re-consider his position. 

. 

3.  Fire Resistance, Compartmentation & Fire-Induced Progressive Collapse ?

Every person participating in the design, construction, management or operation of a building, no matter how simple or complex, must have a working knowledge and proper understanding of the Fire Engineering Principle of Fire Compartmentation:

The division of a building into fire-tight compartments, by fire and smoke resisting elements of construction, in order …

–   to contain an outbreak of fire ;

–   to prevent damage, within the building, to other adjoining compartments and/or spaces ;

–   to protect a compartment interior from external fire attack, e.g. fire spread across the building’s facade or from an adjacent building ;

–   to minimize adverse, or harmful, environmental impacts outside the building.

.

BUT … But … but … buildings are no longer designed and constructed, today, as they were in the 18th or 19th Centuries …

In a fire situation, Fire-Induced Progressive Collapse may commence before any breach of ‘integrity’ occurs in the boundary of such a Fire Compartment, i.e. the building compartment of fire origin.

Fire-Induced Progressive Collapse:  The sequential growth and intensification of distortion, displacement and failure of elements of construction in a building – during a fire and the ‘cooling phase’ afterwards – which, if unchecked, will result in disproportionate damage, and may lead to total building collapse.

… which is related to, but distinguishable from …

Disproportionate Damage:  The failure of a building’s structural system … (i)  remote from the scene of an isolated overloading action ;   and (ii) to an extent which is not in reasonable proportion to that action.

Structural Fire Engineering:  Those aspects of fire engineering concerned with structural design for fire, and the complex architectural interaction between a building’s structure and fabric, i.e. non-structure, under conditions of fire and its aftermath.

.

AND … And … and … a designer of a Sustainable Building will want to utilize … in order to conserve energy … natural patterns of air movement for heating or cooling.  This means that it will be necessary to have gaps between elements of construction which are continuously open … in direct conflict with the Principle of Fire Engineering just quoted above !

What happens when this sort of conflict … or lack of resolution (!) … occurs in modern, highly energy-efficient construction projects ?   At the final stages of approval/certification … the Fire Prevention Officer will insist on following the outdated prescriptive approach in his/her rulebook.  In other words, he/she will illegally apply the guidance text of Technical Guidance Document B as if it were prescriptive regulation.  Fire Compartmentation will be uncompromisingly slapped onto ‘unresolved’ areas of a completed building design … to achieve the limited Fire Safety Objectives of Building Regulations … and the fire safety related construction will probably be badly executed, anyway, because the un-supervised sub-contractors of sub-contractors of sub-contractors couldn’t care less if it goes one way or the other !   The outcome is … nobody wins !!!

In Sustainable Building Design, therefore, Fire Resistance (a ‘passive’ protection concept) must not only be extended to consider a complementary relationship with ‘active’ fire protection concepts, but be stretched … ‘intelligently’ … to embrace the concept of ‘non-construction’ …

Building Sterile Space (Fire):  An open space of sufficient and appropriate extent which is designed to retain an exceptionally low level of fire hazard and risk, and is ‘intelligently’ fitted with a suitable fire suppression system – in order to resist and control, for a specified time during a fire, the advance of heat, smoke and flame.

Fire Resistance:  The inherent capability of a building assembly, or an element of construction, to resist the passage of heat, smoke and flame for a specified time during a fire.

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

Posted by CJ Walsh

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.

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.

Courant 2010, un Site Internet représentant chaque type d’immeuble devrait être mis en place, grâce auquel chacun pourra “tirer des préconisations générales” en matière d’économies d’énergie pour son propre immeuble, même si “cette photographie ne remplace pas un diagnostic thermique”, a précisé à l’AFP l’adjoint à l’environnement de la Mairie de Paris, Denis Baupin.  Le Site montrera quatre photos de façade par bâtiment, la couleur rouge symbolisant les pertes d’énergie les plus importantes.

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.

Buildings of Historical, Architectural & Cultural Importance !

Posted by CJ Walsh

2009-10-08:  Deeply interested … and ‘luuuving’ … a hands-on and direct involvement in the Sustainable Restoration of Buildings which are of Historical, Architectural or Cultural Importance … or even those buildings which are not so important … I am deeply frustrated and angry when I look around at what has happened … and continues to happen … in Ireland … horrible, damaging interventions and alterations of all kinds … too many of which cannot be undone.

Certain guru-like organizations and individuals must be robustly challenged !

Yes … in everyday practice, there are pressures concerning an improvement of energy performance (BER Certificates !) … an improvement of accessibility performance for people with activity limitations (2001 WHO ICF) … an improvement of fire safety performance, etc., etc. … and, in the next few short years, adaptation to climate change will require serious attention.

BUT – BUT – BUT … in dealing with these buildings (a priceless heritage for our children, and their children, which cannot be replaced !) … some absolutely core principles must influence the minds of decision-makers in client and construction organizations, national authorities having jurisdiction, regulators … and, most importantly, the minds and souls of architects and engineers.  (I am wondering … do engineers have souls ?)

.

ICOMOS – International Council on Monuments & Sites / Conseil International des Monuments et des Sites – works for the conservation and protection of cultural heritage places and is the only global, non-governmental organization of its kind.  It is dedicated to promoting the application of theory, methodology, and scientific techniques to the conservation of the architectural and archaeological heritage.  Its work is based on the principles enshrined in the 1964 International Charter on the Conservation and Restoration of Monuments and Sites (Venice Charter).

From practical experience, I have found the 16 Principles of the 1964 Venice Charter to be enormously helpful …

ARTICLE 1    The concept of an historic monument embraces not only the single architectural work but also the urban or rural setting in which is found the evidence of a particular civilization, a significant development or an historic event.  This applies not only to great works of art but also to more modest works of the past which have acquired cultural significance with the passing of time.

ARTICLE 2    The conservation and restoration of monuments must have recourse to all the sciences and techniques which can contribute to the study and safeguarding of the architectural heritage.

ARTICLE 3    The intention in conserving and restoring monuments is to safeguard them no less as works of art than as historical evidence.

ARTICLE 4    It is essential to the conservation of monuments that they be maintained on a permanent basis.

ARTICLE 5    The conservation of monuments is always facilitated by making use of them for some socially useful purpose.  Such use is therefore desirable but it must not change the lay-out or decoration of the building.  It is within these limits only that modifications demanded by a change of function should be envisaged and may be permitted.

ARTICLE 6    The conservation of a monument implies preserving a setting which is not out of scale.  Wherever the traditional setting exists, it must be kept.  No new construction, demolition or modification which would alter the relations of mass and colour must be allowed.

ARTICLE 7    A monument is inseparable from the history to which it bears witness and from the setting in which it occurs.  The moving of all or part of a monument cannot be allowed except where the safeguarding of that monument demands it or where it is justified by national or international interest of paramount importance.

ARTICLE 8    Items of sculpture, painting or decoration which form an integral part of a monument may only be removed from it if this is the sole means of ensuring their preservation.

ARTICLE 9    The process of restoration is a highly specialized operation.  Its aim is to preserve and reveal the aesthetic and historic value of the monument and is based on respect for original material and authentic documents.  It must stop at the point where conjecture begins, and in this case moreover any extra work which is indispensable must be distinct from the architectural composition and must bear a contemporary stamp.  The restoration in any case must be preceded and followed by an archaeological and historical study of the monument.

ARTICLE 10    Where traditional techniques prove inadequate, the consolidation of a monument can be achieved by the use of any modem technique for conservation and construction, the efficacy of which has been shown by scientific data and proved by experience.

ARTICLE 11    The valid contributions of all periods to the building of a monument must be respected, since unity of style is not the aim of a restoration.  When a building includes the superimposed work of different periods, the revealing of the underlying state can only be justified in exceptional circumstances and when what is removed is of little interest and the material which is brought to light is of great historical, archaeological or aesthetic value, and its state of preservation good enough to justify the action.  Evaluation of the importance of the elements involved and the decision as to what may be destroyed cannot rest solely on the individual in charge of the work.

ARTICLE 12    Replacements of missing parts must integrate harmoniously with the whole, but at the same time must be distinguishable from the original so that restoration does not falsify the artistic or historic evidence.

ARTICLE 13    Additions cannot be allowed except in so far as they do not detract from the interesting parts of the building, its traditional setting, the balance of its composition and its relation with its surroundings.

ARTICLE 14    The sites of monuments must be the object of special care in order to safeguard their integrity and ensure that they are cleared and presented in a seemly manner.  The work of conservation and restoration carried out in such places should be inspired by the principles set forth in the foregoing articles.

ARTICLE 15    Excavations should be carried out in accordance with scientific standards and the recommendation defining international principles to be applied in the case of archaeological excavation adopted by UNESCO in 1956.

Ruins must be maintained and measures necessary for the permanent conservation and protection of architectural features and of objects discovered must be taken.  Furthermore, every means must be taken to facilitate the understanding of the monument and to reveal it without ever distorting its meaning.

All reconstruction work should however be ruled out ‘a priori’.  Only anastylosis, that is to say, the reassembling of existing but dismembered parts can be permitted.  The material used for integration should always be recognizable and its use should be the least that will ensure the conservation of a monument and the reinstatement of its form.

ARTICLE 16    In all works of preservation, restoration or excavation, there should always be precise documentation in the form of analytical and critical reports, illustrated with drawings and photographs.  Every stage of the work of clearing, consolidation, rearrangement and integration, as well as technical and formal features identified during the course of the work, should be included.  This record should be placed in the archives of a public institution and made available to research workers.  It is recommended that the report should be published.

Note on BER Certificates for Historical Buildings in Ireland

Unless and until that magnificent marketing and public relations firm … Energy Ireland (SEAI) … can openly show that the DEAP Software has been properly modified to handle buildings of historical, architectural or cultural importance … and this modification is fully transparent … Building Energy Rating (BER) Certification for these building types must be put on hold.
