Case Griffith Residence Lake Travis Subdivision Austin, Texas	3-Star	February 2004	$95

Project Description
This 3,000 sq ft. lake house is located within a small residential neighborhood that was originally master-planned by architect Christopher Alexander. Key design concepts included siting the house for optimum views of the lake, solar orientation and integration into Alexander's scheme. The utilization of sustainable elements in this home resulted in a three star rating by the Austin Green Building Program.

Along with natural lighting and ventilation, shaded fenestration was utilized extensively to reduce energy costs. Allowances for a future rainwater collection system and PV system are also provided. The array of green materials used on this project includes SIP panels for all the walls and roof, which gives an excellent energy rating for the house. Other materials included use of Hardi-panels, stucco exterior (minimal paint), local cedar trim, tile roof with radiant barriers, high efficiency HVAC equipment, and low or no VOC paints and carpets.
