HERS Index - Energy Modeling


D. R. Wastchak uses the RESNET approved energy analysis software Ekotrope to calculate a Home Energy Rate Score (HERS) for homes. 

Home Energy Rating System (HERS Rating) The HERS Index is a scoring system that “rates” a home’s energy usage compared to a code minimum reference home. The details that determine the final HERS score are extracted from the building plans and building performance testing and inspections. The lower a home’s HERS Index, the more energy efficient it is. A HERS Index of 100, would indicate the home complies with the minimum code requirements while a net zero energy home would score a HERS Index of 0. Each 1-point decrease in the HERS Index corresponds to a 1% reduction in energy consumption compared to the HERS Reference Home. For homes to comply with the new 2012 IECC Energy code a HERS index of 65 or less is required. . 

The software takes into account features of the home to calculate the HERS including:

  • Exterior wall framing and insulation
  • Mechanical Equipment
  • Attic insulation
  • Lights & appliances
  • Ventilation
  • Windows & doors
  • etc.

We can also use energy modeling to calculate:

  • Heating & cooling loads
  • Utility costs
  • Energy use
  • City code compliance (IECC)
  • Other energy program compliance
