These are my links for October 5th through October 7th:

• 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)
  * Top 1000 State Owned Enterprises Programme aims to improve energy efficiency in the largest SOEs by 2010…
• 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."

• NYREJ – What works there, can work here: “Green” lessons from around the world – Architects and engineers sometimes lose sight of the bigger picture by focusing too intently on individual (certification) programs. Architects should focus on some of the universal themes found to be successful abroad, pull appropriate concepts and apply
• BREEAM goes to Europe – Property Week – BREEAM Retail Europe will be launched in July and reviewed 12 months later. It will initially cover new and refurbished buildings, but will be extended to older shopping centres at a later date.
• Best Green Companies tables – The Times 50 Best Green Companies venture has both a robust methodology to measure environmental performance and a survey of each company’s staff to find out whether the green sheen is more than skin-deep.

• BREEAM raises stakes – Property Week – ‘Outstanding’ will require an 85%-plus score, whereas ‘excellent’ requires 70%. The new category will set minimum requirements for water and energy consumption in developments. Occupiers will also be able to view compulsory post-construction certi

It can be downloaded free from Sustainable Homes website – www.sustainablehomes.c
• Renew or repair existing window units? A best value approach – "decisions of choice based on quality issues as well as capital cost have given rise to problems within the public sector, leading to financial loss for client organisations in instances where they have failed to adhere to statute or regulatory codes requ
