Introduction to HERS Ratings and Their Significance in the Housing Industry
Understanding the HERS Rating System
HERS ratings, short for Home Energy Rating System ratings, have become a key measure of energy efficiency in the housing industry. But what exactly do these ratings entail? Think of them as a report card for homes, grading energy performance on a scale from 0 to 100.
A lower HERS rating indicates better energy performance, with zero being the ultimate goal for a net-zero energy home. On the other end, a rating of 100 means the home performs at the baseline energy consumption level defined by the International Energy Conservation Code (IECC).
To determine the HERS rating, certified HERS raters use specialized software to analyze various aspects of a home's energy usage, such as insulation levels, air leakage, heating and cooling systems, appliances, and lighting. The resulting score not only provides homeowners with insights into their energy usage but also serves as a marketing tool for builders and real estate agents.
