영문 초록

Windows characterize usage and visual comfort patterns in buildings. Especially for an office building, more buildings have increased window-to-wall ratio (WWR), such as through the use of curtain wall, for a sense of openness and a facade design, though excessive building energy consumption is widely criticized. Therefore, this study seeks to identify the energy consumption characteristics of buildings facing in four orientations (east, west, south and north) with differently designed windows by changing the WWR and considering the component of glazing. The paper showcases diverse measures available to valorise energy consumption. A series of energy criteria was selected and acceptance thresholds were defined for dynamic evaluations. Single zone computer simulations were performed on a standardized office located in Seoul. The results showed that the energy consumption amounts of buildings facing four orientations are affected by the glazing characteristics and the WWR. The detailed results of this study are as follows: 1) Regardless of whether a building faces east or west, when the SHGC increases, the total energy consumption level tends to increase with the same U-value. However, when the U-value increases, the total energy consumption slightly increases. 2) For buildings facing south, the total amounts of energy consumed by buildings with the lower U-value are decreased. However, when WWR increases, the total energy consumption decreases with lower SHGC. 3) As a building facing north has a lower insolation level compared to other orientations, the U-value, related to the thermal capacity influences the energy consumption level of these buildings more than the SHGC.
