How Does an Energy Rating Work?

How Does an Energy Rating Work An energy rating consists of diagnostic testing using specialized equipment, such as: a blower door test, duct leakage tester, and infrared cameras to determine: → The amount and location of air leaks in the building envelope → The amount of leakage from HVAC distribution ducts → The effectiveness of insulation inside walls and ceilings Other variables that are taken into account include: > Floors over unconditioned spaces (like garages or cellars) → Attics, foundations and crawlspaces → Windows and doors, vents and ductwork → Water heating system and thermostats The comprehensive HERS rating provides: A computerized simulation analysis utilizing RESNET Accredited Rating Software to calculate a rating score on the HERS Index. The report will also contain a cost/ benefit analysis for the recommended improvements and expected return on investment. Benefits of an Energy Rating: → Understand how energy efficient a home is > Calculate the accurate cost of homeownership → Enjoy a higher home resale value > Improve home comfort and reduce energy bills RESNET HERS Explaining the HERS Index: INDEX → The HERS Index is the industry standard by which a home's energy efficiency is > A home with a HERS Index Score of 70 is 30% more energy efficient than a measured. standard new home. → HERS Index Score is always relative to the → A home with a HERS Index Score of 130 is 30% less energy efficient than a size, shape and type of house you live in. standard new home. → The lower the number, the more energy efficient the home. → Government agencies such as the Department of Energy (DOE), Department → The U.S. Department of Energy has determined that a typical resale home of Housing and Urban Development (HUD) and the Environmental Protection scores 130 on the HERS Index while a Agency (EPA) recognize the HERS Index as an official verification of energy performance. standard new home is rated at 100.
