Our latest custom home received a Platinum rating under the Florida Green Building Coalition rating system. The home also collected an Energy Star designation by achieving a Home Energy System (HERS) Index score of 56. The HERS baseline score begins with 100 for a basic code-compliant new home. We did not have to use expensive photo-voltaics or other high tech systems to achieve these ratings. Rather, good basic design and construction techniques, and some minimal-cost additional items helped reduce the home's energy use and maintenance requirements.
