The Homes Elevated Program requires builders to achieve a specific HERS score to qualify for each energy efficiency level within the program. To attain the desired certification level, builders must meet the required HERS Index Score, Hers scores do not variate depending on the climate zone 

Builders have the flexibility to choose their own approach to meet the required HERS score for their intended tier. Additionally, a certified rater must be hired to verify that the required HERS score has been successfully achieved
