A new home built to the current energy code uses about 30% less energy than a home built in 2000, according to the US Department of Energy. This recently completed home actually uses less than half of the energy of other new homes.
HERS (Home Energy Rating Score) is performed by an independent energy rater once the home is complete. Many of the products and construction techniques common in Groninger Homes projects offer improved energy performance but the most benefit comes from the attention to details during the construction process.
Much like the stickers found on new cars or appliances, the HERS score card shows that the energy performance of a new home has been evaluated and compared against an established standard, otherwise how will you really know what you are buying?
