These are my links for February 12th through February 18th:

• Building4Change : California to make energy and water saving mandatory – CALGREEN's approach, with its mandatory provisions being inspected and verified by local and state building departments and confirmed in a green label, has led to concerns that it confuses building standards and certification. Questions are being asked in the USA about a number of issues, in particular, lack of third-party assessment and the code's potential to reduce adoption of points-based certification routes, notably LEED.
• The Race to be the Greenest Building – Some great case studies: "The Living Building Challenge, run by the Cascadia Green Building Council, is growing in popularity these days. Referred to as one of the most advanced green building rating systems in the world, it's growing, I believe, in part because of its rigor. The Challenge is performance based, which means a project has to perform as modeled for one full year prior to receiving certification."
• Thoughts on the Renewable Heat Incentive – "As it stands, this incentive will cause oil-fired boilers (as a technology) to be abandoned, without any clear justification. Many people with radiator-based central heating systems looking to replace a boiler will be tempted to switch to a heat pump solely because of the incentive, which looks like it's going to worth around £750-£1,000 a year for 18 years. And yet, unless the heat delivery system is changed (which is unlikely because it would be expensive and disruptive), the energy and carbon burned will actually increase, compared to an A rated oil-fired boiler. For this reason, air source heat pumps, in particular, are ill suited to replacing domestic boilers. There seems little logic in incentivising people to install them instead of efficient fossil-fuel boilers."
• House 2.0: 36 hours in Switzerland – Is a supra-national standard possible? "The Swiss have their own energy saving performance standard called Minergie. It comes in various format. Standard Minergie, Minergie P (roughly equivalent to PassivHaus), Minergie P Eco (with other sustainability features like water saving) and Minergie P Eco Plus (with added renewables). Obviously, this system is never going to be of interest to anyone other than the Swiss; it's all rather like the Code for Sustainable Homes in this respect. Yet another reminder as to how good it would be to have a supra-national standard that everyone could understand."

These are my links for November 14th through November 19th:

• Welcome to amazonails – Enerything you ever needed to know about straw bale building.
• Footprint » Common carbon language – "The ‘Common Carbon Metric’ will be piloted by the leading green building rating tools and made available to anyone dedicated to promoting the understanding and development of a low-carbon built environment. The real impact of this initiative lies in the detail which has yet to be announced, but it is an indication of the growing consensus about the role the built environment can play in mitigating climate change."
• Publications – News & Publications | BioRegional: solutions for sustainability – via Hattie at AJ, I find that BioRegional are making lots of their reports free. Will be interesting to read the One Planet Communities and compare to BREEAM, LEED and Estidama. Communities (rather than buildings) will be the buzzword for 2010. Unfortunately Pooran Desai's book is not free, but can be ordered from Amazon.
• marklynas.org | Closed because of geoengineering works – Mark Lynas on geo-engineering (something I'm really not comfortable with): "Geoengineering deeply divides scientists and environmentalists. Should we really consider spraying sulphates into the stratosphere, planting artificial trees across deserts or dumping iron filings in the Pacific as legitimate options to cool down our planet? Kruger, whose preferred solution involves spreading billions of tonnes of lime in the oceans (see cquestrate.com), likens the approach to having an airbag in a car: it’s better not to crash, but also sensible to insure against the risk that the worst will happen. Plus, “the time to design an airbag is before you are skidding on ice”."
• Predicted vs. Actual: Closing the Gap – "Marcus Sheffer, chair of LEED’s Energy and Environment Technical Advisory Group (TAG), shared some ideas under consideration for the next update to the rating system slated for 2012. The group is closely looking at LEED’s energy credits so that energy simulations more accurately predict performance. For example, the TAG is looking at ways to encourage modeling earlier and more frequently in the design process. “We need to change the practice of validation modeling at the end of a project,” said Sheffer. “We need more iterative modeling.” "
  Interesting comment after the article – can we *really* predict performance?
• Three older houses to be Passivhaus retrofitted – "An architects practice is being funded by the Technology Strategy Board to undertake design and feasibity studies into a proposed scheme to retrofit three empty houses to Passivhaus standard. The Retrofit for the Future competition is designed to address the challenge laid down by the government's target of reducing greenhouse gas emissions by 80% by the year 2050."
• Announcing Living Building Challenge Version 2.0 — ILBI – For those unfamiliar with ILBI, think of it as uber-LEED: "Version 2.0 of the Living Building Challenge expands its focus to local food production, unrestricted access to nature, no gated communities and other equity issues."

These are my links for September 25th through October 1st:

• "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)."
