USGBC to Outsource LEED Certification
May 28, 2008 08:33 AM - , BuildingGreen
In a move that will likely have far-reaching ramifications for the U.S. Green Building Council (USGBC) and its influential LEED rating systems, the organization has announced that as of January 2009 it will no longer certify buildings. That responsibility will pass to independent, accredited certifiers overseen by USGBC’s sister nonprofit corporation, the Green Building Certification Institute (GBCI). GBCI has administered the LEED Accredited Professional (LEED-AP) program since January 2008.
Next Generation of LEED Out for Public Comment
May 21, 2008 08:49 AM - , BuildingGreen
On May 19, 2008, the U.S. Green Building Council (USGBC) opened a public comment period for the most sweeping changes to its LEED Rating System since its original launch in 2000. The changes, which apply to all the nonresidential LEED rating systems that have been formally released, are largely in line with the plan that USGBC laid out at the 2007 Greenbuild conference in Chicago
Top Ten Green Projects of 2008 Announced
April 23, 2008 08:51 AM - , BuildingGreen
The American Institute of Architects (AIA) Committee on the Environment (COTE) has announced its Top Ten Green Projects for 2008. 1. Aldo Leopold Legacy Center (Baraboo, Wisconsin; The Kubala Washatko Architects)—The LEED Platinum headquarters for the Aldo Leopold Foundation uses 70% less energy than a conventional building and achieves net-zero-energy performance. Extensive daylighting and passive ventilation contribute to the energy savings.
A Low-Emissivity Coating That Really Works
March 12, 2008 11:16 PM - , BuildingGreen
To say that there is a lot of hype about insulating paints and radiant barrier coatings is an understatement. The Internet is rife with claims of paints that dramatically reduce heat transfer—usually based on some technological magic spun off from NASA. While these products may have some relevance in the extreme conditions of outer space, manufacturers of paints containing “ceramic beads”¯ or “sodium borosilicate microspheres”¯ are making claims that defy the laws of physics—and independent test results—when they claim they can save significant energy in buildings. Well-engineered coatings with metallic particles can reduce radiant heat transfer, however. LO/MIT-II from SOLEC—Solar Energy Corporation has a long track record of success and is, at least for now, the only such product made with a water-based, low-volatile-organic-compound (VOC) formulation.
Revolutionary Vacuum Glass Coming from Guardian
February 26, 2008 10:41 AM - , BuildingGreen
Guardian Industries, one of the world’s largest architectural and automotive glass manufacturers, with 19,000 employees in 25 countries, has under development a revolutionary vacuum-glazing panel that provides a center-of-glass insulating value of R-12 to R-13. The glass—Guardian VIG (for vacuum-insulated glass)—has a very thin (250-micron or 0.25-mm) space evacuated to 10—4 torr (for reference, thermos bottles typically have a much harder vacuum of around 10—6 torr) between two layers of glass, one of which has a low-emissivity (low-e) coating. Guardian is currently producing the vacuum glazing on a limited basis for testing and hopes to roll it out commercially by the end of 2009.
California to Require Net-Zero-Energy Buildings
February 5, 2008 10:11 AM - , BuildingGreen
Every two years, the California Energy Commission (CEC) releases an Integrated Energy Policy Report in which it makes recommendations for energy policy in the state, including changes to Title 24, the energy efficiency portion of the building codes. In its 2007 report, CEC recommends adjusting Title 24 to require net-zero-energy performance in residential buildings by 2020 and in commercial buildings by 2030. According to Panama Bartholomy of CEC, the commission does not need new legislation to incorporate these goals and is already moving to put them in place. “The 2008 standards will get us closer to these recommendations,”¯ he said, referring to the Title 24 update currently moving through the state’s rulemaking process.
