Links for February 12th through February 18th

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."
