Home Energy Rating System (HERS)
We are not currently not offering HERS Ratings please check out their webiste for directions those that do.
Have confidence when you purchase your next home
Our HERS Rating will cover the following:
-All exterior walls (both above and below grade)
-Floors over unconditioned spaces (like garages or cellars)
-Ceilings and roofs
-Attics, foundations and crawlspaces
-Windows and doors, vents and ductwork
-HVAC systems, water heating system, and your thermostat.
To calculate a home’s HERS Index Score, we will do an energy rating based on your home and compare the data against a 'reference home'– a designed-model home of the same size and shape as the actual home, so your score is always relative to the size, shape and type of house you live in.
How Does a Home Energy Rating Work?
A comprehensive HERS home energy rating, is the most in-depth energy performance assessment of a new or existing home that you can have performed.. It consists of diagnostic testing using specialized equipment, such as a blower door test, duct leakage tester, combustion analyzer 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
- Any existing or potential combustion safety issues
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.
What is the HERS index?
To calculate a home’s HERS Index Score we will do a home energy rating and compare the information against a 'reference home' ( a design modeled home of the same size and shape as the actual home) so the HERS Index Score is comparitive to the size, shape and type of house being inspected.. The lower the number, the more energy efficient the home.
The U.S. Department of Energy has determined that a typical resale home scores 130 on the HERS Index while a standard new home is rated at 100.
- A home with a HERS Index Score of 70 is 30% more energy efficient than a standard new home.
- A home with a HERS Index Score of 130 is 30% less energy efficient than a standard new home.
Developed by the Residential Energy Services Network and introduced in 2006, the HERS Index is the industry standard by which a home's energy efficiency is measured. Government agencies such as theDepartment of Energy (DOE), Department of Housing and Urban Development (HUD) and the Environmental Protection Agency (EPA) recognize the HERS Index as an official verification of energy performance.
