HOME ENERGY SCORING TOOL

 MeasureDescription
Air sealing
The Scoring Tool will recommend Air Sealing where there is a blower door measurement, and the air flow is greater than 1/3 ACH, or where there is no blower door measurement, and the Air Tightness input is set to "No". Otherwise Air Sealing is not recommended.
Attic, basement and floor insulation
Unlike HES pro/con, the Scoring Tool does not have a user selectable upgrade level or payback period. For these ("Type 1") measures, the tool will select the highest available efficiency level that has a simple payback time less than 10 years. 
Type 2 measures  
All type 2 measures are included on page 2 but only those with paybacks of 10 years or less are included in the package savings.
