Energy Advisors (EAs) are experts in home energy efficiency and Building Science and work closely with homeowners, renovators and builders. They're Registered by Natural Resources Canada (NRCan) to deliver the EnerGuide Rating System (ERS) for new homes and existing homes (they may be licensed for both programs). Of note, they are trained to use NRCan's energy simulation software HOT2000 and to perform blower door air leakage testing and have strong knowledge of building codes and standards as well as the performance of a variety of building materials.

EAs have been providing services in Canada for at least 30 years in programs such as the R-2000 Housing program, EnerGuide for New and Existing Homes and the ENERGY STAR® for New Homes Program.

All EAs must pass a minimum of two proctored exams, administered by NRCan, and undergo a rigorous training and mentoring before being able to submit house files and preform on site evaluations. In addition, they are required to retain Commercial General Liability insurance.
