| dc.description | Abstract: This report develops means to evaluate the air tightness of multiple-residence buildings using fan pressurization apparatuses. The fan pressurization apparatuses are mounted in the doors of adjacent attached dwellings, either to equalize pressures between dwellings or to coordinate a pressure difference. Equalization of pressures between adjacent zones permits evaluation of the exterior envelope tightness. Coordination of pressures between adjacent zones permits evaluation of the tightness of party walls or floors. The report discusses the sampling requirements necessary to achieve adequate precision for calculating an equivalent leakage area, L, from each mode of pressurization. Several field studies of multiple-residence buildings at Fort Drum, New York, provided an opportunity to test the principles described in this paper. The buildings measured often had very consistent values of L per unit of envelope area or party wall or roof area within a neighborhood constructed by the same contractor. Confidence limits obtained for calculating L gave a 95% chance of being within bounds determined by the following factors: 1) zone difference measurements had an upper limit of 1.1 or a lower limit of 1/1.1; and 2) pressure difference measurements across a party wall or floor had an upper limit of 1.4 to 5.5 or a lower limit of 1/1.4 or 1/5.5. | - |
