Test Results
In accordance with IECC 2018 the maximum allowable total duct leakage is 4 cfm per 100 sq ft
at+/- 25 pa in the rough or final stage. Currently MA Stretch Code Towns must meet the same
requirements.
Square footage of conditioned space is 1,059 square feet:
- Maximum allowable leakage of 4 cfm per 100 sq ft=42.36 cfm: (4 cfm x 1,059 sq ft/
100 sq ft = 42.36 cfm)
System #1—Servicing the entire conditioned space-
- Tested total duct leakage was 28.76 cfm @ -25 pa
Total duct leakage was 28.76 cfm = 2.72 cfm per 100 sq ft
cfm = cubic feet per minute pa = pascals sq ft=square feet
