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.

Blower Door (Air tightness) Test

WHOLE HOUSE BLOWER DOOR TEST -- 2.20.2017

AVG 145 CFM AT Pascal 50.  ACH = .27

This test was run after interior insulation, drywall, priming flooring but after all shell penetrations.

WHOLE HOUSE BLOWER DOOR TEST -- 11.8.2016

AVG 190 CFM AT PASCAL 50 = ~ .36 ACH


whole house blower door  11.8.2016

ach 160 cfm at Pascal 50.

This was the first recorded test post demo and major construction and was run before interior insulation, drywall, paint and flooring but after all shell penetrations.


This was the very first Blower Door test run before demo and construction. Visible daylight around windows was present.
