Air leakage test was carried out according to ASTM E779-03, Standard Test Method for Determining Air Leakage Rate by Fan Pressurization to meet the requirements of the LEED-NC v2.2(EQp2). Air leakage tests for quality assurance can be performed once all work on the air barrier has been completed and all windows and doors have been installed in two high-rise residential buildings. Test units selection was carried out in accordance with the following guidance, California’s 2001 Energy Efficiency Standards. That is, 1 in 7 dwelling units was sampled, and dwelling units were grouped for testing according to unit size and type. Finally, we completed pressurization and de-pressurization tests for 240 residential units and the final readings were a level of 0.87 square cm per square meter of surface area or less.
