What Is an Energy Rating?

An energy rating measures residential home efficiency by evaluating:

• Air and duct leakage
• Insulation levels
• Window efficiency
• Wall-to-window ratios
• Heating and cooling systems
• Solar orientation
• Water heating systems

The rating uses a standardized scale based on a national energy code — the HERS Index — to determine how energy efficient a home is and whether it qualifies for programs like ENERGY STAR.

Benefits of an Energy Rating

For homebuyers: Compare energy costs between new homes and make more informed purchasing decisions.

For existing homeowners: Receive a detailed analysis showing the most cost-effective improvements to reduce energy bills and improve comfort.

For builders: Verify code compliance, qualify homes for ENERGY STAR certification, and apply for energy efficiency tax credits.

For everyone: A documented record of your home's energy efficiency measures and performance.
