High-performance green building on Hilton Head Island

Introducing the market to high-performance green building on Hilton Head Island

Coastal Habitats constructed a series of Building America (BA) homes at the Bryant Park community in Hilton Head, SC. Based on analysis by Building Science Corporation (BSC), the homes were expected to reach >40% source energy savings (Rudd and Feldman 2007) compared to the BA Benchmark (Hendron 2008) through the use of air-tight spray foam insulation, energy efficient windows, high efficiency mechanical systems, and other measures. The ventilation system featured an innovative combination of central-fan-integrated supply (CFIS) and single-point exhaust methods. One of the Molly plans (Lot 8), which underwent detailed long-term monitoring, also had a solar domestic hot water (SDHW) system, resulting in projected source energy savings of 46% over the BA Benchmark. An additional Molly plan without solar hot water (Lot 9) was used for short-term ventilation system testing.
