Assured. <br />TEST REPORT FOR WESTWOOD INVESTORS, LLC <br />Project No.: N8834.01-901-43 <br />Date: 06/02/23 <br />"-"N7 <br />TEST PROCEDURE <br />ASTM E779 Whole Building Air Leakage Test (Single Zone): <br />The whole building air leakage test was performed in general conformance with ASTM E779 <br />TEC Model 3 fans were utilized to uniformly pressurize and depressurize the building. <br />Pressurization and depressurization tests consisted of measuring the total fan air flow (cfm) <br />required at each of six equally spaced building pressure differentials. During pressurization <br />the minimum induced pressure was 50 Pa and the maximum induced pressure was 75 Pa. During <br />depressurization the minimum induced pressure was -50 Pa and the maximum pressure was - <br />75 Pa. The test pressure was measured in representative locations such that pressures in <br />the extremities could be monitored to determine if they were within 10% of the induced <br />enclosure pressure. The pressure variation was verified at the highest test pressure. Enclosure <br />pressures from key elevations of the building and interior building pressure differences were <br />reviewed and used to conduct the analysis of test results. Baseline pressure readings were taken <br />across enclosure and averaged over two minutes each, before and after test flow measurements. <br />Page 5 of 18 <br />
