After working with your rater to decide on a set of upgrades that comply with the HERO code, begin installing upgrades in your new starts. Insulation levels can be "traded" in the HERO compliance calculations (handled by your rater). For example, you can reduce attic insulation if you make up for it by adding wall insulation or framed floor insulation. (Each home design will behave slightly differently and trade-offs should be considered with a Rater's input.)
The program requires that all homes achieve 4 ACH50 on blower door testing and 4% duct leakage (LTO) on duct blaster testing. All rebates are based on kWh savings.
