We often hear folks, especially from out of state, ask us: “Do Alturas Homes have HERS index scores?” While Alturas Homes does have HERS index ratings, we want to answer your questions and ensure that energy conservation is still a top priority.
What is the HERS index?
HERS stands for the “Home Energy Rating System.” This nationally-recognized index rates homes from 0 to 150 on energy efficiency and consumption. The lower the number, the more energy-efficient the home is. Similar to Energy Star, RESNET partners with companies to certify raters around the country to give homes HERS index scores.
What does a HERS index score mean?
The HERS index rates a score of 100 to homes built to the 2004 International Energy Conservation Code, which is the standard starting point of energy efficiency. A typical resale home scores 130 and is 30% less energy-efficient than a standard new home. A score of 0 (Net Zero) signifies that a home creates as much energy as it consumes through renewable resources and excellent construction.
What determines a HERS index score?
HERS certified raters look at many indicators when scoring a home, including:
- Exterior walls (above and below grade)
- Floors over unconditioned spaces (garages or cellars)
- Ceilings and roofs
- Attics, foundations, and crawl spaces
- Windows, doors, vents, and ductwork
- HVAC systems, water heating system, and thermostat
- Leakage in the heating and cooling system
Raters look for how well parts of a home are sealed, built, and installed for maximum energy conservation.
What is the benefit of a HERS index score?
Having a HERS index score can give insight on what aspects of the home need to be improved for energy conservation. A home with a low HERS score benefits from:
- Lower utility costs
- Greater comfort from reduced temperature fluctuations
- Higher appraised value
- Possible decreased mortgage default risks
Alturas Homes currently does not use RESNET raters to score our homes. Why don’t we use HERS index scores? There are several downsides, including an extensive time allocation to inspections and increased cost to buyers. Also, the Boise area has limited access to RESNET certified raters and contractors.
Regardless of labels or ratings, we never stray from high-quality construction. Alturas Homes keeps up to date on the current Idaho residential building regulations, which follow the 2012 International Energy Conservation Code.
In addition to the Idaho building code, we have high standards, in which we strive to provide an exceptional new home experience from start to finish. Fifty years of experience has taught us never to sacrifice quality because our homeowners deserve to find a home they love.
If you still want a HERS index score, there are options. Anyone can get HERS index score by finding a RESNET Home Energy Rater in the Treasure Valley.
