The Home Energy Rating System (HERS) Index is the industry standard by which a home’s energy efficiency is measured. It’s also the nationally recognized system for inspecting and calculating a home’s energy performance.
The lower a home’s HERS Index, the more energy efficient it is. A home built to code scores a HERS Index of 100, while a net zero energy home scores 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. Thus, a home with a HERS Index of 85 is 15% more energy efficient than the reference home and a home with a HERS Index of 80 is 20% more energy efficient.
PEA Builders homes have an average HERS Index of less than 35!

Consideration of dew point and condensation in the walls is a key factor in our wall systems.
