A HERS Index of 100 is a home built approximately to the 2007 National Energy Codes
The HIGHER a HERS Index is ABOVE 100 - the WORSE its energy performance.
The LOWER a HERS Index is BELOW 100 - The BETTER its energy performance.
A New Home built to IECC 2009 Energy Code will typically have a HERS Index in the 60-80 range.
A New Home built to IECC 2012 Energy Code will typically have a HERS Index in the 40-60 range.
