초록

본 연구에서는 커튼월 건물에 적용가능한 슬림형 이중외피 커튼월시스템에 대하여 블라인드 개폐와 개구부 구성에 따른 태양열취득률(SHGC) 성능시험을 실시한다. KS L 9107에 근거한 SHGC시험을 실시한 결과와 ISO standard 15099를 근거로 개발된 Window/Therm 프로그램을 이용하여 산출한 값을 비교한 결과 5% 범위 이내에서 유사한 결과가 나왔다. 개발된 이중외피 시스템대하여 유리의 종류와 블라인드의 슬릿각도에 따라 총 20가지 종류에 대하여 SHGC를 도출하여 설계를 위한 기초자료를 제시하였다.

영어초록

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.
