Slide40Size Adjustment Factor
Note:
Renewable energy systems may not be used to qualify for the ZERH HERS Index Target Score, but may be used for the incremental HERS Index points needed for the Size Adjustment Factor.
Homes larger than the benchmark home size must use the size adjustment factor to determine the target HERS index
