If you’re in the market for a new home, or thinking about updating your existing home, you might have seen the term “HERS Score” floating around. Many of you are probably wondering: What on earth is a HERS score and why does it matter? Here are the basics…
- HERS stands for Home Energy Rating System
- Your HERS rating measures your home’s energy efficiency
- It is a nationally recognized system for inspecting, testing, and calculating a home’s energy performance (source: HersIndex.com)
- A HERS score of 100 is the average rating of a home built to the 2006 International Residential Building Code (source: MN Green Path)
- A LOWER score is better! The lower the score, the more energy efficient the home.
Now that we’ve discussed the basics, you might be wondering, “How exactly is a HERS score determined?” In short, a certified professional analyzes various aspects of your home–the quality of your exterior walls, your windows, the ceiling and roof, your HVAC system, air leakage, etc. The professional collects data and compares your home’s performance to 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 the house you live in.
Today’s typical score for a new home? Around 80. Homes today must comply with stricter energy standards than in 2006, but there’s still plenty of room for improvement. OPTIMA Homes, for instance, consistently have a HERS rating of 40 or less. That’s at least 60% more energy efficient than home building standards in 2006 and 90% more efficient than the typical resale home!
Having a low HERS score saves you money (a home with a score of 40 gives you approximately $1,616 per year in energy savings according to HersIndex.com), increases home comfort, and reduces your carbon footprint. Whether you’re doing it for your family, the environment, or as a financial investment, striving to achieve high home energy efficiency just makes sense.
