• Energy Efficiency Partnership for Homes – Partnership Publications – EEPH/CLG report: "This report presents results and findings of the joint EEPH (Energy Efficiency Partnership for Homes) and Department for Communities and Local Government (CLG) project to study the levels of compliance with Part L of the Building Regulations.
  Specifically, it presents the results from a study of compliance for new dwellings built since April 2006 in accordance with Approved Document L1A (2006). The results for the full sample for the 2nd Phase of the project are presented"
• The future of green building in China – ClimateChangeCorp.com – Interesting (long) article on green building in China: "Perceived high cost is another barrier. When a World Business Council for Sustainable Development survey in 2007 asked the real estate developers and building professionals worldwide how much more they thought green buildings cost than normal buildings, the Chinese respondents said they thought certified green buildings cost 28% more. They were unaware that in China the average extra cost for a LEED certified building has been 3-5% more. This figure is similar to the global average incremental cost for LEED certified buildings.
  Lewis says as long as the Chinese developers have a perception that green buildings cost a quarter more, they will surely not go for green projects."
  China’s green building targets
  * Reduce building energy use in all cities by 50% by 2010 and 65% by 2020 (base year 1980)

• Target Zero – About Target Zero – AECOM have been commissioned by Corus and BCSA: "The aim of this project is to understand the implications of the UK Government's move towards 'zero carbon' for five steel framed non-domestic building types.
  Target Zero will research and cost options for improving operational energy consumption and reducing embodied energy and other life-cycle impacts. The fully costed solutions generated will demonstrate how to achieve the three highest BREEAM ratings and meet the anticipated changes to Part 'L' of the Building Regulations."
• Zerofootprint » Communities – Interesting competition to retrofit a post-war, pre-90's concrete building and operate at net zero for a year. Their definition of net zero is on-site NOT community level, and by my reckoning excludes biomass: "All the energy required to power household amenities, cool, heat, and light the building must be provided on a net zero basis. Possible onsite energy systems can include wind, solar, bio-fuel cells (from occupant produced organic waste), hydrogen cells, etc. Energy must be produced by devices located within the building and its nearby property, and cannot be powered by fuel brought to the building. The building can contribute excess energy to the grid and, when necessary, access an equivalent amount, but no more."
• Passivhaus Windows | GreenBuildingAdvisor.com – I've been slightly obsessed with window u-values recently. This article has a great overview of German vs. US calculations differences and some good suppliers for windows from Canada: "When I interviewed Dr. Wolfgang Feist in 2007, he told me, “The reason for the number which we now use in Europe is the comfort of the occupants. It is a functional definition. During the winter, the coldest surface temperature in the room will be the window. If you don’t have a radiator in your room, the difference between the surface temperature of the window and the mean surface temperature of the room should not be more than 3 degrees Celsius; that’s for comfort reasons.”
  The colder the climate, the more important it is to use U-0.14 or better windows in a Passivhaus building — and not just for comfort. Low U-factor windows are necessary to meet the Passivhaus maximum annual heating energy standard of 15 kWh per square meter."

• "Passive" Heating and Cooling Is a Misnomer. It’s Active. : TreeHugger – "there are 36 Billion square feet of non-residential buildings from the 50s through the 80s that need to be retrofitted and greened. It ain't going to be easy."
• AIArchitect This Week | Buildings Brought to Life: The First Project to Meet the Living Building Challenge Is Only Months Away – "For a building to meet the Living Building Challenge it must consume net-zero energy and water. It must produce net-zero waste. It must choose an ecologically responsible site and maintain it. Inherently unsustainable materials (like lead, mercury, and formaldehyde) are not allowed, and there’s a limited radius from which materials can be transported to the building site during construction. Indoor air quality must be maintained, and, among many other requirements, all of these sustainability features must be featured in educational materials and programs at the building. Since the challenge was formulated in 2006, no building has met it."
• Don’t Underestimate the Power of Information in Pursuing Sustainability | GreenerBuildings.com – "The Energy Passport is a related idea that could be implemented much more easily. Conceived in the early '90s by Dr. Yuri Matrosov of the Moscow Center for Energy Efficiency (CENEf), Energy Passport programs were first adopted in Moscow, then in Germany, which is now pushing for it to be implemented in the EU as a whole.
  The initial Energy Passport is based on modeled energy use and then actual energy use is compared each year with predicted use, which then could be accessed by tenants and others. Clearly, comparing actual energy use with predicted energy use, as well as consumption trends over time, would give designers and developers an incentive to get the prediction right in the first place (parenthetical note, without clear modeling rules it is shockingly easy to game the results of energy models), as well as provide a clear benchmark for operators to manage their buildings more closely."
• Glass Industry Raises Concerns Over ASHRAE 90.1 Revisions That Could Reduce the Use of Glass in Nonresidential Buildings – Impact of potential changes to prescriptive route for ASHRAE 90.1 (similar to old elemental method for Part L) for glazing: "The proposal does not recognize or accommodate the need for different glazing solutions across climate zones. It is a "one size fits all" approach and will limit the glazing choice to a small range of high transmission, clear low-E glazings. They are not the appropriate products in all climate zones, especially the Southern cooling-dominated climates because of the sunlight intensity. Use of such high transmission glass in those climate zones will likely result in greater use of blinds resulting in increasing lighting energy usage.
  …There is only limited possibility for saving energy in buildings unless the space also includes automatic daylighting controls. Even with recent proposals, daylighting controls are only required in rooms where the "primary side-lighted area" is less than 1,000 square feet. …"
• How to keep your mouth shut « Scott Berkun – Oh, I have been here many times. Like Scott, I'm recovering ;o). Read the whole post: "But then later on, in a new job at Microsoft in a group known as MSTE, I discovered a world of dysfunction, despair and passive/aggression. No one spoke their mind in public. Few people worked hard or asked tough questions. Quality of work, and morale, was low. So I soon felt obligated to mention these facts as often and as loudly as possible to leadership. I even expected to be rewarded for telling people how bad things were. Why wouldn’t they want to hear this? I thought.
  Before I knew it, I was that guy. The guy who always complains."

• Constructing Excellence in the Built Environment » Blog Archive » Ethics and the Built Environment (by Jon de Souza) – If consultants only get involved at the Jus in Bello stage, is it ethical to build immoral buildings? Waiting avidly for part 2: "At present, the discussions about ethical behaviours in construction largely consider what happens after a decision has been taken to construct – the Jus In Buildo stage if you will. (Told you). What is missing is consideration of that former stage – the question asked is “can we build it”, but not “should we”. This seems to chime with our view of the world – that there are some things that simply shouldn’t be built. I mean, can any of us really morally defend snow domes in Dubai?"
• UK notches strong gains in renewable capacity in 2008 – Politics – Renewable energy news – Recharge – wind, solar, biofuels, wave/tidal/hydro and geothermal – "The UK’s installed renewable generation capacity surged 19% in 2008, thanks largely to a 727 megawatt (MW) increase in onshore wind capacity and a 192MW boost in offshore wind, according to new government statistics.
  At the same time, the amount of electricity produced from renewables in the UK rose a more modest 10%, to 21.6 gigawatt hours (GWh)."

These are my links for July 14th through July 16th:

• Sustainable Homes – This could open the doors for more LA's to impose CSH (and BREEAM?) levels for planning conditions: "Chelmsford Borough Council requires that Code for Sustainable Homes Level 3 is achieved as a planning condition for new buildings. The developer appealed against this condition but following consideration by the Planning Inspectorate the condition was held as "reasonable and necessary"."
• House 2.0: On triple glazing – Mark Brinkley warming to the idea of Passivhaus: "comfort underlies the PassivHaus take on triple glazing. I have been a voice arguing that triple glazing is “overkill” in the UK climate and that the energy used in making these units would probably never be repaid by the energy saved over their lifetime. However, the main reason for using triple glazing is not to save energy but to provide more comfort, as the internal temperatures remain more even.
  Feist produced a table showing what the temperature differences were close to different forms of glazing when the internal temperature is designed to maintain at around 21°C and the external temperature drops to —5°C.
  • next to a single glazed window, the adjacent temperature is around 1°C
  • next to a double glazed window (2000 vintage), the adjacent temperature is around 11°C
  • next to a triple glazed window, with a centre pane U value of just 0.65, the temperature is 18°C."
• Portland Architecture: A man struggling: Guy Battle comes to Portland – Guy stands up for engineers: "Do engineers deserve more credit?
  Yes, I think so. Engineering is the hidden hand. They have an enormous amount to contribute to architecture, but too often their contribution is gently put to one side. I think it’s something that should be celebrated. You look at someone like Peter Rice or Neil Thomas, Chris Wise, Guy Nordenson, and a host of other fantastic engineers, and they don’t really get the recognition they deserve."
• Ashden Awards (Jonathon Porritt) – Kirklees (again): "Kirklees Metropolitan Borough Council – one of the unsung heroes of local government who have been doing their "sustainability bit" for the last 20 years. But their current home insulation initiative has really made people sit up and listen as it has succeeded in achieving real scale – where so many of the current measures are just picking around at the edges. Here’s what the Award citation said:
  "In 2007, Kirklees Council committed £10 million to providing free loft and cavity-wall insulation for every home in the borough where it can be used. The scheme targets one council ward at a time, using the local Councillor and local advertising, then individual home visits by assessors. By May 2009, 66,000 out of the 172,000 households in the borough had been assessed, 54,000 referred for surveys, 26,000 surveys had been completed, and 21,000 had insulation installed. This avoids an estimated 18,000 tonnes a year of CO2. 140 jobs have been created by the scheme.""
• Cutting carbon with smart finance | Forum For The Future – Innovative financing examples: "For instance, Kirklees’ Re-Charge scheme loans householders money to install low-carbon technologies in their property, such as solar panels to heat water. It is successful because there are no interest charges and the money does not have to be repaid until the property is sold. The council only has to subsidise the interest on the loans and this costs around three times less per home than using a grant scheme."
• FT.com / Weekend columnists / Tim Harford – Carbon footprinting: time to pick up the pace – The ever lucid Tim Harford:"The carbon-footprinting process often produces surprises. An environmentally conscious consumer in the crisps aisle of the supermarket will probably be thinking about packaging or “food miles”. The Carbon Trust reckons that about 1 per cent of the climate impact of a packet of crisps is from moving potatoes around. The largest single culprit is the production of the nitrogen fertiliser, and half of the climate impact in general takes place at the agricultural stage. The point is not that agriculture is always the problem, but that it is very hard for a well-meaning consumer to work out what the green purchasing decision actually is. For this reason, the Carbon Trust has a carbon labelling scheme. The trouble is that many consumers simply do not care enough to pay more or choose a less enjoyable product simply because of the low carbon label."
• Ground Control | PD Smith | Kafka’s mouse – Minton's book duly added to my wishlist. Review: "Sections of our city centres are being sold off to private developers to create shopping monocultures such as Westfield London or "malls without walls" like Stratford City, which is being built for the 2012 Olympics and is one of the largest retail-led developments in Europe. It is, says Minton, "a private city within a city" and represents a return to the early 19th century when aristocrats owned great swathes of London, fortifying their estates of up-market housing with gates and private security forces.
  Now, “land and property which has been in public hands for 150 years or more is moving back into private hands”. Minton argues that today’s privatised city centres and gated communities are fostering "a new culture of authoritarianism and control"."

• Sustainable Design: What Do Europeans Know That We Don’t Know (But Should)?- 3/1/2009 – Building Design & Construction – "The respective roles of regulation and market forces are quite different in Europe from what we expect in the U.S. and Canada. That's one of the fundamental current differences that are likely to converge over the next five years, as the U.S. and Canada face up to the carbon reduction challenge. Generally speaking, in Europe, and especially in the U.K., people expect their governments to regulate, so government incentives for energy-efficient buildings are less prevalent there than they are in the U.S., or even in Canada."
• Top 10 Myths about Sustainability: Scientific American – Fantastic (long) article:
  Myth 1: Nobody knows what sustainability really means.
  Myth 2: Sustainability is all about the environment.
  Myth 3: “Sustainable” is a synonym for “green.”
  Myth 4: It’s all about recycling.
  Myth 5: Sustainability is too expensive.
  Myth 6: Sustainability means lowering our standard of living.
  Myth 7: Consumer choices and grassroots activism, not government intervention, offer the fastest, most efficient routes to sustainability.
  Myth 8: New technology is always the answer.
  Myth 9: Sustainability is ultimately a population problem.
  Myth 10: Once you understand the concept, living sustainably is a breeze to figure out.

• ArchNewsNow – WORDS THAT BUILD: Re-invent Green Communication – Great article from a great series. Can easily substitute BREEAM for LEED and it will read the same: "Your goal is to filter the enormous written text of LEED and deliver the gist of relevant LEED issues into commonplace and yet engaging English. This isn’t as quixotic as it might initially sound. The advantage of LEED language over odious “GREENSPEAK’ or “ECOMARKETBABBLE” is that it traffics in concrete specifics within building systems. The downside of LEED language is that it borders on “official” bureaucrat-ese,” the palaver of numbed technocrats."
• House 2.0: Why sash windows work – "in a critical passage in Part F, the ventilation regulations, there is a reference that says that, when replacing windows, rapid ventilation should not be made worse. Up until now, no one has challenged the assumption that this simply means that the openings should be of similar size. But it transpires that a single opening casement is far less effective at rapid ventilation than a combination of top and bottom openings."
• Sustainability in practice: Carbon profiling | Design details | Architects Journal – "Sturgis carries out carbon profiling using a bespoke software program that measures the embodied carbon of a building over its lifetime to ascertain its whole-life carbon footprint. Part L requires a calculation of operational energy-use, the Building Emission Rate (BER), which is calculated in kgCO2/m2/year. Carbon profiling uses these same units to measure Embodied Carbon Efficiency (ECE), including allowances for the demolition and transport associated with the building. The total annual carbon cost of a building is the sum of the BER (operational energy) and the ECE (embodied energy).
  Each component of a building is analysed. For example, an aluminium panel and glass cladding system can be compared with a concrete panel and glass cladding system. The concrete system uses about 20 per cent less carbon to construct than the aluminium and will last approximately two to three times longer. Therefore, the ‘carbon cost’ over time is significantly less for concrete than for aluminium."
