Riverview 1 I WSEC Air Barrier Testing Report <br /> q avi4 . <br /> Test Equipment and Building Test Preparation Procedures <br /> Testing was conducted by deploying 6 high-capacity Retrotec 3000SR orifice blower door fans, installed in <br /> exterior entry doors. Below is an outline of the measures taken to ensure only legitimate leakage through the <br /> envelope was measured. <br /> -isolated bathroom and laundry exhausts <br /> -isolated range exhausts <br /> -isolated toilets, plugged bathroom and kitchen sinks with water or masking <br /> Upon successful installation of the fans, the building was pressurized sampling differential pressure in 5 Pa <br /> increments. Before and after each test, zero-flow baseline pressures were taken and used to correct the final <br /> pressure measurements. The resulting pressure and flow data points were then plotted to determine their <br /> correlation and identify the pressure exponent and leakage coefficient which are indicative of the building's <br /> leakage characteristics. <br /> Report Conclusion <br /> ASTM E779-15 testing performed by Soloveda indicates that the building enclosure air tightness capabilities <br /> meet or exceed the formal performance requirements set forth in 2015 WSEC Section C402.5.1.2. <br /> Congratulations on a successful test at Riverview Building J! <br /> Regards, <br /> o/na/A,a z 47ti a e7-.('kl i.)4 <br /> Operations Manager <br /> Soloveda Division II LLC <br /> 206.850.5950 <br /> Jonathan@Soloveda.com <br /> This report was prepared for Soloveda's client and contains findings,comments,and observations made by a qualified representative of Soloveda.
