Abstract

This paper presents an airtightness study conducted on a new construction building. The focus of the study was on evaluating the effectiveness of the employed air barrier system in achieving airtightness. The wall, ceiling, and floor air barrier systems were examined, consisting of polyethylene sheets, self-adhered membranes, and concrete structure. The building underwent a whole building air leakage test following ASTM E779 standards. The initial test revealed significant air leakage, primarily due to punctures in the air barrier system after drywall installation. Remediation measures were implemented, including sealing sprinkler caps, fasteners, and door weather stripping. Subsequent tests showed improved airtightness, with the measured air leakage rate falling within the specified target. The successful remediation efforts enhanced the building envelope’s airtightness, leading to improved temperature control, reduced energy consumption, and increased occupant comfort. This study emphasizes the importance of conducting air barrier installation commissioning even after drywall installation and highlights the significance of proper training for builders and occupants to prevent damage to the air barrier system.
