What does my HERS rating mean?

Your HERS rating measures your home’s energy efficiency using a nationally recognized system. It compares your home to a standard reference home built to meet basic energy codes. By inspecting and calculating its energy performance, the HERS Index assigns a score ranging from 0 to 150 or higher.

The lower the score, the more energy-efficient your home is. A score of 100 matches the energy performance of the standard reference home set by the U.S. Department of Energy. Scores below 100 show above-average energy efficiency, while a score of 0 means the home produces as much energy as it consumes, achieving Net Zero Energy status.

What is the HERS rating process?

A HERS rating is a comprehensive evaluation of a home’s energy efficiency and performance. The rating is conducted by a certified HERS rater who follows a standardized assessment process. Here’s how a HERS rating typically works:

1. Initial Assessment: The HERS rater begins by collecting information about the home, including its size, construction materials, insulation levels, HVAC systems, and appliances. They also review building plans and may conduct an on-site inspection.

2. Energy Modeling: Using specialized software, the HERS rater creates an energy model of the home, simulating its energy consumption based on the provided information. The model establishes a baseline for comparison.

3. On-Site Testing: The rater performs various tests to measure the home’s energy efficiency. This includes conducting a blower door test to assess air leakage, using infrared cameras to identify insulation gaps or thermal issues, and verifying the performance of HVAC systems.

4. Data Analysis: The collected data from the on-site tests and the energy model are analyzed to calculate the home’s HERS Index. The HERS Index is a relative score that indicates the home’s energy efficiency compared to a standard reference home.

5. Report and Recommendations: The HERS rater provides a detailed report that includes the HERS Index score and a breakdown of energy-consuming components. It also offers recommendations for energy-saving improvements. This helps homeowners understand where their home stands in terms of energy efficiency and provides guidance on potential upgrades.

6. Post-Improvement Verification: If energy-efficient upgrades are made, a HERS rater can perform a post-improvement verification. This assessment measures the impact of the upgrades on the home’s energy performance. The HERS Index may be revised based on these results.

By undergoing a HERS rating, homeowners gain insights into their home’s energy efficiency, receive a quantifiable HERS Index score, and obtain recommendations for improvements that can enhance energy efficiency, reduce utility costs, and improve overall comfort.
