HERS® Transparency Explained: A Homeowner’s Guide to Your Energy Efficiency Data

How it Works

A HERS® Rating provides valuable insight into a home’s energy performance, balancing transparency, accuracy, and practicality. This guide highlights the information that’s readily available to homeowners.

Homeowners have access to verified performance data through the RESNET® Registry, including key scores, savings estimates, and certification details. Additional documentation may be available through the builder or developer.

This structure provides homeowners with reliable performance information, along with a defined pathway to request further details about their home’s Rating.

Your Home’s Energy Snapshot

Homeowners can view key performance details through the RESNET National Buildings Registry. This resource provides a verified snapshot of your home’s energy performance, including:

• HERS Index Score, HERS H2O® Index Score, and HERS Carbon Index® Score
• Estimated annual energy use and cost savings
• Estimated carbon and water savings
• Builder, HERS Rater, and Rating Provider information
• Software used for the Rating
• Any certifications, such as EPA ENERGY STAR® or WaterSense®

How to Access Additional Information

As HERS Ratings are typically commissioned during construction, the builder is often the original client for the Rating. As a result, homeowners interested in more detailed documentation can request this information through their builder.
