Blower Door Tests
Multiple blower door tests were performed over the course of the project with different equipment and under different ambient conditions. The first blower door test performed shortly after acquisition showed infiltration / exfiltration of over 5700 CFM at 50 Pascals on an building that was approximately 40% smaller. Subsequent blower door tests resulted in ranges well below the Passivhaus Institut limits, namely, in the .35 and less ACH at 50 Pascals range. Current infiltration/exfiltration approximates 200 CFM with 1 stdev +/- 25 CFM at 50 Pascals.
