Q: What software can do the calculations for these types of mortgages?
A: The national group that works with the various stakeholders on Energy Efficiency is the Residential Energy Services Network, RESNET.
RESNET approved Software packages are available through a network of Rating Providers. These Rating Providers perform QA on all Certified HERS Ratings.
There are currently three software programs accepted by RESNET for HERS Ratings. They are used across the US for Energy Efficient or Energy Improvement Mortgages.
• Energy Gauge
• Energy Insights
• Rem Rate
• The Kansas Energy Office has designated Rem Rate for use in state operated weatherization and efficiency programs.
