What is one way to enhance the HERS rating of a home?

Installing energy-efficient windows is a substantial way to enhance the HERS rating of a home. Energy-efficient windows are designed to minimize heat transfer and reduce the amount of energy required for heating and cooling. By incorporating features such as double or triple glazing, low-emissivity coatings, and gas fills between panes, these windows improve a home's thermal performance. They help in maintaining comfortable indoor temperatures while reducing reliance on heating and cooling systems, ultimately leading to lower energy consumption. This reduction in energy usage positively impacts the HERS rating, demonstrating that the home is more energy efficient, which is a key focus of the HERS Index.
