HERS (Home Energy Rating System)

The Home Energy Rating System (HERS) is a scoring system that measures a home's energy efficiency. A HERS score ranges from 0 to 150, with lower scores indicating better efficiency—meaning the home uses less energy for heating, cooling, and appliances. Energy raters conduct an assessment, evaluating factors like insulation, windows, and HVAC systems. This rating helps homeowners understand their energy use and identify areas for improvement. It can also influence home value and marketability, and some buyers seek energy-efficient homes to reduce utility bills and environmental impact.
