Abstract

Recently, interest in passive building techniques has been increased to improve the energy efficiency of buildings. Accordingly, airtightness has become increasingly emphasized to reduce energy costs of heating and cooling attributable to infiltration and exfiltration. In this study, we compared airtightness value for apartment and mixed-use residential buildings, and evaluated the airtightness according to the airtightness quality construction. We conducted airtightness measurement using fan pressurization method for 37 units in 3 residentail buildings. As a result, the airtightness of the apartment unit was measured airtight. The airtightness was poorly measured for units with a drywall. And the airtightness was measure at a level of about one-third of the building with airtight quality construction.
