Fox Blocks, an Insulated Concrete Forms (ICF) manufacturer, in partnership with GreenBuilt Solutions, a sustainable design facility in Orlando, FL, has managed to build a Net Zero home that has an outstanding HERS Index Score of -22.
The Home Energy Rating System (HERS) Index is the industry-wide standard energy-efficiency measurement of homes. It is also used to determine a home’s energy performance. The lower the HERS Index Score on a home, the more energy-efficient it is. The national average HERS rating posted by RESNET is 58.
“Turning Leaf Construction’s Parade Home in Winter Park is an extremely high performing home achieving a HERS rating of -22,” says Nate Ritter, Director of Sustainability for GreenBuilt Solutions. “It is beyond Net-Zero. One of the most important features in high-performance homes is starting with a well-insulated air-tight envelope like ICF’s. [Using Fox Blocks], ICFs helps provide stable indoor air temperatures, significantly reducing cooling and heating loads and cost.
