Abstract

To reduce the condensation risk and secure the comfort of occupants, the Korean Design Standard for Preventing Condensation in Apartment Buildings has been in force since 2014. However, window systems in the market rarely satisfy the condensation resistance criteria for severely cold Region I of which design outdoor air temperature is $-20^{\circ}C$. The aim of this study is to suggest the window design alternatives enabling to satisfy both the condensation resistance criteria for Region I prescribed in the Design Standard and the U-factor criteria prescribed in the Korean Construction Standard for Energy-efficient Green Home. A variety of alternatives were selected for double-glazed PVC-framed horizontal sliding double window, the most commonly used in Korean apartment buildings. Condensation resistance of glazing edge and window U-factor were evaluated using heat transfer simulations. As results, six alternatives were suggested, which satisfy the criteria of condensation resistance for Region I and U-factor.
