HERS Rating

Would you buy a new car without knowing its “miles per gallon” efficiency? Then why buy a home without a knowing the “home energy rating?”

The Home Energy Rating System (HERS) Index, developed by the Residential Energy Services Network (RESNET) in 2006, has become the industry standard of how home energy efficiency is measured.

What to Know About the HERS Index

  • The HERS Index accounts for a home’s energy consumption of cooling, heating, electricity, water heating, lights, and some appliances from a 0 to 250 point scale.
    • “250”is a very poor rating and likely to have more costly energy bills due to several home inefficiency problems.
    • “100” is the standard the same energy as a new home that meets California’s 2008 Building Energy Efficiency Standards.
    • “0” is a super-efficient “Net Zero Energy Home” that consumes no more energy than it produces from onsite renewable sources.
  • 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 awarded a rating of 100.
  • Every 1 point change on the HERS Index scale equates to a 1% change in energy efficiency.
  • The HERS Index helps estimate a home’s annual energy use, operating cost, and greenhouse gas emissions.
  • HERS calculates the amount of solar or other onsite renewable energy that the home may produce.

With a HERS Index rating of -13, Blue Zero homes are 8 TIMES MORE ENERGY EFFICIENT than newly built standards of today

The HERS Index calculates a home’s energy efficiency. The lower the score, the more energy efficient the home is.

What Makes Blue Zero Homes So Energy Efficient?

  • Blue Zero homes have a HERS rating of minus 13, which is more efficient than net zero homes and far below the HERS national average of 100 for standard new builds.
  • Super insulated, airtight construction conserves BTUs generated by winter heating systems and summer cooling.
  • Renewable energy is included in each home to offset the energy used with well designed solar panels to save on utility bills.
  • Our whole house ventilation systems and fresh air intake filters improve the quality of air in the home while reducing allergens.
  • Energy Star rated low energy windows help reduce the need for regulated heating/cooling and is sealed tight to keep outside air from entering the home.
