HERS Testing

Verify energy efficiency and performance

New homes under construction today have significant focus on energy efficiency. Depending on the results of the energy calculations for your Project, your building or units may require testing by a HERS Rater to verify the performance of the home’s energy efficiency.

PIW’s Home Energy Rating System (HERS) raters will verify the performance of the building’s energy efficiency. A HERS rater certified by CHEERS and Calcerts in California, and RESNET outside of California, will provide all the necessary testing, including:

  • QII – Quality Insulation Installation
  • Duct Leakage Testing
  • Blower Door Tests
  • Cooling Coil Airflow Verification

  • SEER/EER Verification
  • Domestic Hot Water Systems Verifications
  • Solar (PV) Verification
  • Cal Certs Certifications
