Results
Air Flow @ 50 Pascals :
1625 CFM50 +/- 0.9%
3.10 ACH50 (Air Changes Per Hour)
Effective Leakage Area (LBL) = 100.36 Square Inches +/- 3.9%
Equivalent Leakage Area (CANADA) = 180.71 Square Inches +/- 2.4%
Estimated Natural Infiltration (50 Pascal Flow Divided By 13.6)
= 120 CFM
= 39.9 CFM/OCCUPANT
