Despite the increasing popularity of green building, research on high-performance building practices and technologies represents a tiny percentage of federally funded research. According to a report released in March 2007 by the Research Committee of the U.S. Green Building Council (USGBC), only 0.2% of federally funded research, an average of... Read more

Launched in March 2007 by Architecture for Humanity (AFH), the Open Architecture Network is an online, interactive database and workspace for designers and architects to share projects and ideas. Uploaded projects are protected by Creative Commons licenses, which allow authors and designers to grant some or all of their copyrights to the public... Read more

The California Energy Commission (CEC) filed suit against the U.S. Department of Energy (DOE) in April 2007 to require DOE to uphold California’s washing machine efficiency standards. In December 2006, DOE denied the State’s 2005 request for a waiver from federal washing machine standards; the waiver would have allowed California to enact... Read more

Nuclear power is increasingly being touted as a leading solution to global climate change. Nuclear energy proponents—and a growing number of environmentalists—correctly point out that nuclear fission, the heat source in nuclear power plants, does not emit greenhouse gases. Given the clear need to reduce our carbon dioxide emissions, nuclear... Read more

The American Institute of Architects, American Society of Heating, Refrigerating, and Air-Conditioning Engineers, Architecture 2030, Illuminating Engineering Society of North America, and U.S. Green Building Council have reached an agreement setting a baseline for the goals of the 2030 Challenge, which calls for an immediate 50% reduction in...

Drywall comes in three primary product types. Paper-faced drywall remains by far the dominant product for finishing interior walls. It is inexpensive and easy to work with (cutting panels by scoring and snapping). Environmentally, the paper is typically 100% post-consumer recycled, the gypsum core can be derived from flue-gas-desulfurization (... Read more

The Athena Sustainable Materials Institute has released a new life-cycle assessment (LCA) tool for assemblies. The EcoCalculator for Assemblies draws on results from Athena’s Impact Estimator for Buildings to give instant LCA results for over 400 building assemblies, including those for walls, roofs, floors, and windows. Commissioned by the... Read more

The Collaborative for High Performance Schools (CHPS) has recognized the Greenguard Children and Schools product certification program from the Greenguard Environmental Institute (GEI) as a means of improving indoor air quality in school buildings. GEI’s product certification program complies with California’s Department of Health Services... Read more

A report from the United Nations Environment Programme, titled “Buildings and Climate Change: Status, Challenges, and Opportunities,” details connections between the building industry and efforts to curb greenhouse gas emissions. According to the report, which focuses primarily on Europe, more rigorous energy efficiency standards there could... Read more

In a perfect world, energy simulations and design tools would be so well integrated that each time an architect moved a wall, added a window, or changed a lighting specification, the building’s predicted energy performance would be updated and displayed instantly. With that sort of real-time feedback, designers would quickly become skilled at... Read more

Michael Potts has replaced Amory Lovins as CEO of the Rocky Mountain Institute (RMI), the Colorado-based nonprofit and self-described “think and do tank.” Potts has been a member of RMI’s board of trustees since 2005. He previously served as CEO of software design company American Fundware, and, most recently, as a managing partner at Galway... Read more

Much has changed in the U.S. Green Building Council’s Technical Scientific Advisory Committee [TSAC] final report on PVC [see

EBN

Vol. 16, No. 3]. In this round, TSAC expanded its analysis to account for life-cycle issues that traditional LCA (life-cycle analysis) tools often miss, such as disposal issues and occupational... Read more
