In an effort to provide consumers a fun way to learn about how the HERS® Index works and what the scores mean, RESNET has posted an interactive HERS® Index tool as the home page of its consumer site As you move the score of the HERS® Index the tool will graphically indicate the resulting cost savings, reduction of carbon emissions and increased comfort of the home. The estimated average cost savings from the changing the HERS® Index score was developed by the National Renewable Energy Laboratory. The site states that the savings numbers are for educational purposes only and that for specific information on a particular home the consumer should have a home energy rating conducted by a certified RESNET Home Energy Rater. To view the the new HERS® Index interactive tool click on HERS® Index This education tool will enforce the movement of builders that commit to having their homes energy rated and marketing their homes HERS® Index.
