TC Legend Homes built this 2,463-square-foot home in Seattle, Washington, to the performance criteria of the DOE Zero Energy Ready Home (ZERH) program.
The home’s high-performance SIP walls and roof combined with advanced HVAC and a 9.5-kW solar electric generating system plus solar water heating to provide the homeowner with nearly $1,900 in annual energy cost savings compared to a similar-sized home built to the 2012 IECC.
Advanced lighting is used throughout the entire home—all of the lighting is LED.
The home’s open floor plan makes good use of the highly efficient triple-paned windows, which flood the home with natural light.
Low-flow water fixtures and faucets were installed throughout the home to improve water conservation.
An ENERGY STAR-rated refrigerator and dishwasher are installed in this home for increased energy savings.
This home qualified for the EPA Indoor airPLUS certification, indicating that it meets a host of air quality specifications.
The home’s high-performance building envelope consists of structural insulated panels (SIPs) –- walls are 6-inch R-29 panels covered with house wrap and roofs are 10-inch R-42 panels covered with ice-and-water shield for an airtight, water-resistant, highly insulated home.
