Part of the final performance testing of this home was our third party testing.  We tested the home for duct tightness, air tightness, and indoor air quality.  Our final numbers for the blower door test on this home were 1.25 ACH@50 (60% better than Energy Star 3.0 requirements) which with our insulation values, mechanical systems, lighting, and appliances led to a HERS score of 35.  HERS ...
