The heat bridge in buildings means the site showing the heat energy loss more compared to other sites. It may give occupants an unpleasant feeling due to the performance drop in buildings, so it should be minimized. The energy loss by the heat bridge occurs more in the passive house buildings with good air-tightness and insulation performance compared to general buildings.
This study targeted on the windows and outer wall joints with large energy loss due to heat bridge. As a result, it was analyzed that the linear thermal transmittance(Ψ) value in the windows and outer wall joints, varied up to about four times according to the installation location of frame. Additionally, the minimum temperature in indoor surface varied significantly according to the frame location. In final, according to the analysis of the equivalent U-value change in windows according to the change of Ψ-value, the larger the window size, the bigger the equivalent U-value because of the increase of length occurring the Ψ-value.
As such, the U-value of window should be calculated considering the Ψ-value as well as the proportion of frame. Additionally, it"s possible to evaluate more exactly the energy only through the application of the equivalent U-value applying the Ψ-value in time of calculating the energy of buildings. For this purpose, this study presented a correction factor so that the Ψ-value of frame changing according to the location of frame can be applied to the frame U-value.
