Currently MA Stretch Code Towns must meet the same requirements. Square footage of conditioned space tested is 1056 square feet: - Maximum allowable leakage of 4 cfm per 100 sq ft=42.24 cfm: (4 cfm x 1056 sq ft/100 sq ft=42.24 cfm) System#1—Servicing the 151 Floor— - Tested total duct leakage was 39.59 cfm @-25.0 pa Total duct leakage was 39.59 cfm=3.7 cfm per 100 sq ft cfm=cubic feet per minute pa=pascals sq ft=square feet Target Inspections Summary of Testing Results Copyright 2010/2011 Disclaimer:Although we seek to provide the most accurate information possible we cannot guarantee any findings may or may not be changed due to environmental conditions or contractor decisions/actions that are beyond our control.Target Inspections is not responsible for Improvements as a result of our inspection. Page 3 of 4 TARGET INSPECTIONS Conclusion Based on testing of the total duct systems,the observed total duct leakage at the time of testing of the one (1)system was at or below the allowable limits (4 cfm per 100 sq ft) as set forth in IECC 2015 with tested results of 3.7 dm per 100 sq ft. The systems as installed meets the recommended guidelines and no further sealing is required. Note 1:Square footage provided by town assessor web page. Note 2: Baseline measurements are based on 60 second averages. The systems as installed meet the recommended guidelines and no further sealing is required. 3 4•••••---4. rerA,'rf,' ' a� ` a I @ -24.8 ; in 39.59 IV,lI a.... 114 l (. bitVM am. S..In,.
