Deep dives
The History and Purpose of Home Energy Rating Systems (HERS)
The podcast explores the development of the HERS industry in California, which was established in response to the energy crisis in the 1970s. The Warren Alquist Act was passed, granting authority to the California Energy Commission to develop energy efficiency standards and codes. HERS raiders are compliance raters who verify the energy efficiency of HVAC system installations and perform tests such as duct leakage and refrigerant charge. Additionally, HERS raiders assess the energy efficiency of existing homes by measuring various parameters and generating a home energy score based on a scale. The podcast also discusses the transition from using specific software to partnering with national HERS organizations like ResNet, which is bringing the home energy industry into the 21st century.
