100 minus 32 = A Big Difference … A standard new home is expected to be rated at about 100 on the HERS (Home Energy Rating System) scale. The HERS index is the industry standard by which a home’s energy efficiency is measured and the lower the number, the better the result. Our recent construction in Erie Michigan came in at a very impressive 32 on the HERS index. When you shop for builders be sure to ask each what HERS rating their homes have received. Reduce your operating costs and increase your comfort level with a Moline built “Certified” Energy Star home.
