Welcome to CalCERTS.

HERS Training

The California Energy Commission is required by Public Resources Code Section 25942 to establish regulations for a Home Energy Rating System (HERS) Program to certify home energy rating services in California. CalCERTS adheres to the Energy Commission’s requirements for certifying Home Energy Raters who perform third-party inspections for verification of energy efficiency features of new and existing building construction.

Since 2003 CalCERTS has been approved by the California Energy Commission to implement educational programs and certification of Home Energy Rating System Raters in order to serve a critically important function for ensuring high quality installation of energy efficiency features in California homes and small commercial HVAC installations. CalCERTS certified Home Energy Raters work hand-in-hand with local building departments. Raters provide the documents required by the Building departments before finalizing building permits that use HERS measures to show compliance with Title 24, Part 6, Building Energy Efficiency Standards. Home Energy Ratings can also establish a benchmark of a home’s energy use and identify necessary and/or the best energy efficiency upgrades for home and buildings. Home Energy Ratings are entered by HERS Raters into the CalCERTS data registry for government agencies to access.

The goal of the Building Energy Efficiency Standards is to ensure reliable energy efficiency levels in California homes and buildings to guide investment in cost-effective home energy efficiency measures.

Our educational programs and training courses are instructed by CalCERTS Instructors who are subject matter experts in building energy efficiency.  The course work leads to one or more of the following:


  • HERS Residential Alterations Certification
  • HERS Residential New Construction Certification
  • HERS Nonresidential Certification
  • HERS Solar Certification
  • HERS Whole-House Home Energy Rating Certification
  • HERS Building Performance Contractor Certification
  • Energy Efficient Mortgage (EEM) Certification
  • ENERGY STAR® Certification
