This home is a participant in CenterPoint Energy's High Efficiency HomesTM, which promotes high efficiency home construction.
The RESNET Home Energy Rating System (HERS) score rates homes against an index of the code reference home of 100. The lower the score, the more energy efficient the home. Older homes often score 130 or higher. In Minnesota today, new homes built to code generally test about 80. The Air Changes Per Hour at 50 Pascals (ACH50) is the index used in blower door testing to indicate how airtight a home is. As with HERS, the lower the score the more energy efficient the home. Minnesota‘s Green Path is a program of Housing First Minnesota.
