초록

A double skin system for curtain wall buildings has been proposed as an energy efficient system because it is known to minimize environmental impacts from outside while utilizing natural conditions. If applied with appropriate plans, various environmental advantages can be secured, such as reducing heating load by thermal buffering in winter, and cooling load by blocking. Although a variety of methods have been devised for reducing building energy consumption in double skin window systems, improving insulation performance has generally been the main focus, unfortunately which causes overheating in summer, not only increasing cooling loads but also resulting in thermal discomfort for residents. Therefore, quantitative performance analysis data such as Solar Heat Gain Coefficient (SHGC) of the developed Slim-type Double Skin Window (SDSW) Systems need to be presented in order to reduce cooling energy consumption. In this study, various SHGC tests of the SDSW system using solar simulator have been conducted in conditions of blinds open and closed, and in different window opening positions. Simulation evaluations applying these data were carried out for comparison with the values obtained by SHGC experiments. Values of the SHGC tests based on KS L 9107 ranged from 0.07 to 0.30. Furthermore, Simulation tools Window grounded on ISO 15099 were used for calculating SHGC, and these results were within 5% of the SHGC test values as per KS L 9107. In total, SHGC data of 20 type samples are presented for the developed SDSC system, and the samples are categorized according to the glass type and the blind slit angles.
