What Is a HERS Rating And Why Does It Matter?
HERS Ratings & Certified HERS Raters in Texas – Real Energy Performance for Your House
HERS stands for Home Energy Rating System — the nationally recognized standard to measure a home’s energy efficiency.
The HERS Rating assesses the energy efficiency of a home using many factors, including construction features, insulation, air leakage, HVAC systems, home appliances, and on-site electricity generation. The ratings, which are scored on the HERS Index, are:
- 100 = standard home constructed according to the 2006 International Energy Conservation Code (IECC)
- Lower scores = more energy efficient
- A HERS score of 65 indicates the home is about 35% more energy efficient than a standard code-built home
At Green Building Energy Sustainability (GBES), our specialized RESNET HERS Raters apply the following criteria to ensure accurate HERS energy ratings (including codes) for new construction and existing homes, using advanced modeling software such as Ekotrope.

Performance Testing for Real-world Accuracy
To ensure energy performance has met what it needs, GBES conducts the following inspections and tests;
- Inspection of insulation and air sealing
- Blower door tests to identify air infiltration (ACH)
