Donat certified as HERS rater

Catherine Donat, owner of Four Seasons RESource Inc. of Bemidji, has achieved certification from Environmental and Energy Raters Alliance of Manhattan, Kan., a RESNET provider, as a home energy rater.

Home Energy Rating System certification required 40 hours of classroom and hands-on training of residential building science and blower door use, passing the RESNET national raters exam and completing three home ratings independently.

Also a partner of the Department of Energy program Energy Star, Donat is able to pass newly built homes as meeting Energy Star efficiency standards, meaning the home as a system is more energy efficient than a reference model home and will ultimately save the homeowner money normally spent on utility bills. She can also work with builders and contractors from the planning stages of residential construction to qualify the builder for the EPA Tax Credit.

HERS index ratings can also be given to existing homes to qualify for Energy Efficient Mortgages or Energy Improvement Loans, or for a home purchaser to be assured the home is energy efficient.
