ASTM International has published a new standard for investigations of indoor air quality problems in residential buildings. Standard D-7297 contains guidelines for an initial assessment of possible indoor air quality problems and a subsequent three-phase process for finding the sources of any problems. A first-phase walk through the house is... Read more

Members of the U.S. Green Building Council (USGBC) approved a measure that effectively increases the minimum energy performance of LEED-certified projects by 14% for new buildings and 7% for major renovations. Introduced in November 2006, the measure requires all projects to obtain a minimum two out of ten points in the energy optimization... Read more

Both houses of the Connecticut legislature and Governor M. Jodi Rell have approved a bill expanding the state’s ban on pesticide use on school grounds and playing fields. A similar bill, passed in 2005, prohibited the use of pesticides on public and private elementary school grounds starting in 2006, but gave schools until July 2008 to... Read more

In passing the 1996 Food Quality Protection Act, Congress required the U.S. Environmental Protection Agency (EPA) to test pesticides for disruption of the human endocrine system, which produces and regulates hormones. After years of delays, EPA announced in June 2007 that it would test 73 pesticides that people commonly encounter in homes and... Read more

The term "volatile organic compound" (VOC) means different things to different people. In high school or college chemistry class we learned that VOCs are a class of carbon-based compounds that readily become volatile (gaseous) under ordinary (atmospheric) conditions. Thus, we learned that VOCs are any of those carbon-based compounds that smell... Read more

One can hardly pick up a magazine or turn on the television today without hearing something about climate change. The issue finally appears to be gaining traction in our nation’s collective consciousness. Much of the focus of reducing greenhouse gas emissions rightly centers on how we design and construct buildings. Indeed, the 2030... Read more
