C017 — Development and Experimental Evaluation of a Zonal Infiltration Measurement Method for Multi-Unit Residential Buildings: Error Analysis, Performance Evaluation, and Study of Building Characteristics

Click here to purchase
Air leaks in buildings are important to be measured since they impact energy use and indoor air quality (IAQ). A novel Zonal Multipoint Pressure Testing (ZMPT) procedure is presented that determines a zone’s external and internal leakage parameters from one test procedure, in contrast with conventional methods. This paper reports the results of an experimental comparison of the ZMPT and conventional methods in a number of new and existing buildings, proposes a method to quantify leak measurement uncertainty, and compares the trade-offs between single point and multipoint tests in terms predicting the naturally occurring low-pressure leakage.
