Ozone depletion and global warming are two of our most serious environmental problems—and foam insulation materials containing CFCs (chlorofluorocarbons) contribute significantly to both of these problems. The environmentally concerned builder or designer should make it a highest priority to avoid them. Even many of the non-CFC alternatives... Read more

Q.Where would you say architects as a group stand on environmental issues?

A.Architects tend to be reactive rather than proactive. It is important that we take the lead on these environmental issues. The architecture schools in particular tend to be conservative. They just aren’t... Read more

There are so many great contractor-related sessions at Greenbuild this year! I doubt I'm alone in trying to choose between sessions.  

Is there interest in debriefing with SCLers the week after (say Novemeber 9th at 2pm ET?). We could share the golden nuggets from the sessions we attended, saving everyone from wading through the session... Read more

Does anyone know of a good summary of state and local energy code adoption for new building and ordinances for existing buildings? I know of this energycodes.gov site, but it feels somewhat misleading when you dig into it. For example, in CO, it suggests there is no min code, but there is, and it doesn’t show the extent to which local govs are... Read more
