This course trains students who wish to be Certified Home Energy Raters (HERS Raters / ERI Verifiers) in the basics of home energy ratings and prepares them for the RESNET National Rater and Practical Simulation exams. It also includes RESNET Combustion Safety and Workscope Training to prepare them for the RESNET national CAZ (Combustion Appliance Zone) testing and practical simulation exams. Please note, this training does not include education on onsite blower door testing, duct blasters, or ventilation testing. If you required training in these areas, please contact us so we cab connect you with a qualified trainer. However, this is not required outside of the US.
Raters are required on residential green building certification programs such as, but not limited to, LEED Residential, Enterprise Green Communities, National Green Building Standard and GreenStar Homes Certification.
The Course Length is about 2 – 8 weeks, and it involves 100 hours of on-demand virtual learning; it is not a live course.
Course Cost $1,200 for GreenHome Institute Members.
NOTE: The textbook “Residential Energy” by Krigger and Dorsi is required for this course.
Review the additional FAQ items before enrolling in the training below.
International raters outside of the United States and Canada will take a different approach. The energy professional must have experience evaluating the energy efficiency of at least two residential buildings. Currently, under LEED addenda 10443, preliminary ratings are not required. Please note, this training does not include education on onsite blower doors, duct blasters, and ventilation testing. If you require training in these areas, please contact us so we can connect you with a qualified trainer. However, this is not required outside the U.S.

For those in the US, Once you have completed this on-line portion of the training, you will need to take the required national exams in the presence of the instructor. This is the first phase in your journey to become Certified as a HERS Rater. To complete your certification once you have successfully completed training and passed the exams, you must also gain hands-on experience with the tools and perform testing and verification under the guidance of a RESNET Rating Provider. You will then complete a minimum of five (5) probationary ratings with your chosen Rating Quality Assurance Provider within one year of successfully completing the exams. Your Rating Provider is the certifying body who will provide you with your final HERS Rater certification.
As a HERS Index Rater or ERI Verifier, your role is crucial in delivering benefits to your clients. Your certification allows you to help them achieve Energy Star or DOE Zero Energy Ready Certification, which can lead to them achieving tax credits or utility rebate incentives such as the Inflation Reduction Act 45L Tax Credit, worth up to $5,000 per multifamily unit or single-family development. These same certifications may apply to local or state tax credits or utility rebates, such as the Consumers Energy rebate of up to $20,000 per home or unit. On top of that, many of the building codes are moving to allow or require the Energy Rating Index to meet the code, meaning you can play a role in verifying code requirements for projects.
