Savings are estimated during the initial energy audit using approved software. At the moment, it appears that two specific tools are approved for this: TREAT (Targeted Retrofit Energy Analysis Tool) from PSD Consulting and Real Home Analyzer (no details online that we can find) which is Conservation Services Group’s in-house tool. There is some controversy amongst the Maine energy efficiency professional community about the variability of results when using each of these tools. We’ll stay on top of it, and keep this updated.
