HERS Home Energy Rating New home buyers: Does the new home you’re interested in have a HERS Rating and Energy Star score? Ask the builder for a copy of the report and certificate. Compare the reports you get from the homes you like. This is the true story of how energy efficient your new home will be. No HERS Rating! Ask why! The typical cost to a builder in Iowa for a HERS rating and Energy Star score is $400, so it can’t be the cost. Builders and Contractors: IMPORTANT! Energy Star, RESNET, EPA and the IRS require a pre-drywall inspection to quality for any of their programs. Be sure to provide adequate notice to your rater so they can schedule your pre-drywall inspection.

HERS Ratings – The nationally recognized barometer for home energy use Know (and improve) the HERS score before you start work. The Home Energy Rating System (HERS) is the nationally recognized, investment grade computer model trusted by the US EPA/DOE joint Energy Star for Homes program. The HERS score is used to award many millions of dollars of energy improvement incentives annually. HERS is also used for Energy Efficient Mortgage applications. HERS is used to qualify for the nationally recognized USGBC Leadership in Energy and Environmental Design (LEED) green building program for homes. Use the HERS Score to market your homes, use the HERS energy performance metric to objectively demonstrate how your buildings are superior to the competition.

Home Energy Rating System


Home energy ratings provide a standard measurement of a home's energy efficiency. Ratings are used for both and new and existing homes. In new homes, ratings often verify energy performance for the ENERGY STAR速 homes program, energy efficient mortgages, and energy code compliance. Homeowners who want to upgrade the home's energy efficiency can use the energy rating to evaluate and pinpoint specific, cost-effective improvements. For existing homes, homeowners can receive a report listing cost-effective options for improving the home's energy rating. An energy rating allows a home buyer to easily compare the energy performance of the homes being considered.

There are two types of ratings: Projected & Confirmed Projected ratings - Ratings performed prior to the construction of a home or prior to the installation of energy improvements to an existing home. Confirmed ratings - Ratings completed using data gathered from an on-site inspection, which could include performance testing of the home. Confirmed ratings involve an on-site inspection of a home by a residential energy efficiency professional, a home energy rater. Home energy raters are trained and certified by a RESNET accredited home energy rater training provider. The home energy rater reviews the home to identify its energy

characteristics, such as insulation levels, window efficiency, wall-to-window ratios, the heating and cooling system efficiency, the solar orientation of the home, and the water heating system. Performance testing, such as a blower door test for air leakage and duct leakage, is usually part of the rating. The data gathered by the home energy rater is entered into a RESNET accredited computer program and translated into rating score. The home receives a score between 1 and 100, depending on its relative efficiency. An estimate of the home's energy costs is also provided in the report. The home's energy rating is then equated to a Star rating ranging from one star for a very inefficient home to five stars for a highly efficient home. Unlike an energy audit or a weatherization assessment, a home energy rating is a recognized tool in the mortgage industry. Home energy ratings can be used in a variety of ways in the housing industry. The star and the rating score provide an easily understandable means to compare more efficient homes by their relative energy efficiency, since a rating quantifies the energy performance of a home.
