  • How It Works - What Does Your New NV Home's HERS Index Number Mean?

    A standard new home is awarded a baseline rating of 100 on the Home Energy Rating System (HERS) Index. The lower a home rates on the HERS scale, the more energy efficient it is. For example, a home with a 70 rating is 30% more efficient than a standard new home, and a home with a 130 rating is 30% less efficient than a standard new home. And older, resale homes are typically far less efficient than any new homes.

    By purchasing a new, energy-efficient NV home and knowing its official HERS rating, you can:
    • Compare its energy usage to other homes in the market
    • Know the projected utility costs savings you'll enjoy living in your new NV home
    • Have peace of mind that you're being easier on the environment while lowering your monthly utility bills

The estimated energy costs and savings take into account typical usage and costs at a given point in time for a specific model of home in a specific location. Actual savings will vary and will depend on many variable factors and a change in any of these variables or assumptions could result in reduced cost savings or higher energy costs. Such variables include, but are not limited to, homeowner behavior, actual utility usage and consumption, the fluctuating cost of energy, actual weather conditions, and home and equipment maintenance over time.
