Purpose: Leakage of building envelope introduces unintended infiltration, heat and moisture into a building and affects building energy, indoor air quality and occupants comforts. The purpose of this study is to measure airtightness of multi-family residential buildings with different structural systems. Method: Fan pressurization and depressurization tests using a blower door was used to measure airtightness and air leakage of the buildings by KSL ISO 9972. There are three differential structural types as bearing-wall (A-wall), flat-plate (B-Flat), and rahmen (C-B&C) in the same complex. The proposed four units of multi-family residential buildings were measured airtightness and air leakage of building envelope. The four units were three ones accroding to differential structural types and last one (C-B&C-1) installed with external wall (dry-cladding) systems on rahmen structure. Result: The results of pressurization and depressurization tests show that the air leakage of A-wall was 3.5 ACH50 and one of C-B&C-1 was 5.6 ACH50. The air leakage of B-Flat and C-B&C were 4.25 ACH50 and 4.15 ACH50, respectively. |
