Preliminary Home Energy Rating Results
Based on the assumptions described above, we have calculated the following Preliminary Home Energy Rating results.
Preliminary HERS Index: 54
Estimated Mass Save Rebate: $2100*
Note that Confirmed Home Energy Rating results may vary from the Preliminary Home Energy Rating results due to
changes in building plans, energy features installed in the home, RESNET standards, software changes, and other
factors.
* = Mass Save Residential New Construction requirements and incentive amounts can change at any time without
notice at the discretion of program sponsors. We anticipate, but do not guarantee, that current program requirements
and incentive amounts will apply to this project as long as it is completed and inspected by June 30, 2018.
