The U.S. Fish & Wildlife Service's Parker River National Wildlife Refuge recently completed the $8 million renovation of its 7,700 sf visitors center, 5,500 sf administrative offices, and 6,000 sf of refuge support building space. Architect Cambridge Seven Associates, Cambridge, Mass., specified 57,000 sf of metal panels for its exterior walls and standing-seam roof, both featuring Kynar 500 / Hylar 5000 finish in a dove gray color. The material is Energy Star-compliant and provides an emissivity level of 0.90 on the roof, which meets LEED criteria for cool roofs. According to refuge manager Janet Kennedy, the need for sustainable design and construction practices was a priority. "We're as green as we can be," says Kennedy. "That is important to us. As a natural resource agency, if we don't do it, who will? It's important to walk the talk." The project's GC was T.R. White Co., Boston.
