Effective airflow control is an important aspect of building performance that contributes to ventilation energy efficiency, occupant comfort and safety. However, the lack of accessible interzonal airtightness measurement methods inhibits the implementation of meaningful compartmentalization standards in multi-unit residential buildings. The feasibility of two novel approaches were investigated. Using sound transmission loss as an indicator of air leakage rate across suite partition walls, the estimate accuracy of 0.59 L/s/m2 remains inadequate for compliance verification at 1.53 L/s/m2, but it could be a feasible approach for screening air leakage rates between similar partitions. Correlation models specific to typical wall assemblies could be developed in the future to improve this accuracy. When MEMS absolute pressure sensors were used to monitor air pressure differentials, after applying calibration and noise removal techniques, sensors with ±3 Pa rating produced pressure differential estimates of ≤10 Pa accuracy, which appeared adequate for selective operational airflow monitoring applications.
