Careful Air Sealing Trims Energy Use at New College Dorms

Sep 29, 2010 | Bar Harbor, Maine

By Hal Bohner

In the cold climate of coastal Maine, effective air sealing is critical to maximizing energy efficiency. The architect for the project, Bruce Coldham, said, “We have tried many approaches to air sealing over the past twenty years, but we hit the jackpot with these buildings. The results were spectacular. We achieved a remarkable final airtightness of 0.79 ACH50 consistent over three similar buildings. Without the comprehensive air-sealing design and implementation, the buildings would have been seven-plus times leakier.”

Easy LEED Platinum?

Sep 3, 2010 | Washington, District of Columbia

“It was easier than I thought,” says Amy Levin when first asked about her LEED for Homes Platinum gut rehab. This would not be the last time my jaw would drop when dealing with Amy; she is a completely unflappable, sharp as a tack, force of nature. She is a born problem-solver and her favorite retort is most certainly “why not” rather than “why.” The devil is always in the details; here is the rest of the context on Amy’s “easy” version of LEED Platinum.
