Materials Selection
The concrete structure’s thermal mass is leveraged to reduce heating and cooling loads, and create a stable indoor climate even during extreme temperatures. Plastic tubing embedded into slabs circulates cold or hot water depending on needs. Materials were selected based on regional availability, potentially hazardous components and recycled content. The project achieved 46 percent regional materials, 26 percent recycled content, and 90 percent certified wood in accordance with LEED guidelines. Fly ash used in the concrete reduced carbon dioxide emissions by 1.3 million pounds. Sustainable interior finish materials include linoleum, bamboo, FSC-certified wood, recycled-content concrete, and Green Label Plus carpeting.
