A home energy rating involves a thorough analysis of a home's construction plans as well as on-site inspections. Based on the home's plans, the Home Energy Rater uses energy efficiency software to perform an energy analysis of the home's design. This analysis provides a projected, pre-construction HERS index.
Upon completion of the plan review, the rater will work with the builder to identify the energy efficiency improvements needed to ensure the house will meet ENERGY STAR performance guidelines. The rater then conducts on-site inspections including a calibrated blower door test that measures the leakiness of the house and a duct test that measures the leakiness of the ducts. The results from these tests, along with the analysis for the plan review are used to generate the HERS Index for the home.
A home energy rating is a recognized tool in the mortgage industry. A home energy rating can qualify a home-owner or home-buyer for an energy efficient mortgage (EEM) or an energy improvement mortgage (EIM). An energy rating can maximize the value of a home for the home-owner. Home energy ratings can be used in a variety of ways in the housing industry. Since a rating quantifies the energy performance of a home, the HERS Index provides an easily understandable means to compare the relative energy efficiency of different homes.
