The parts of building which has the most influence on thermal load are skins, outer walls and windows. Among them, window is the worst weak point of building even if it has many advantage of solar radiation gain than other parts. The present time, many researches on various performance of window and many types of system-window are being made. This study evaluates thermal performance of tilt & sliding system window by simulation program Therm 5.2 and Window 5.2. After making a sample model improving it's thermal weak point, this study evaluates real thermal performance of system window. As a result, this study understands manufacture ability condition of domestic company and proposes a research plan of system window.

The aim of this study was to analysis the Heating/cooling performance and Daylighting performance of Solar Window System built in apartments. the solar window is the idea to integrate daylight as a third form of solar energy into a PV/Solar Collector system. The process of this study is as follows: 1)Solar Window system was designed through the investigation of previous paper and work. 2)The simulation program(Lightscape3.2) was used in daylighting performance analysis. the reference model of simulation was made up to analysis daylighting performance on Solar Window system. 3)The simulation program(ESP-r, Therm5.0, Window6.0) was used in energy performance analysis. the reference model of simulation was made up to analysis energy and daylighting performance on Solar Window system. 4)The Size of Simulation model for daylighting and heating/cooling energy analysis was $148.5m^2$ 5)The lighting performance analysis was carried out with various variants, such as the size and installed area of Solar Window system. 6)Energy performance simulation was carried out with various variants, such as Integrated U-value of Solar Window system according to its position, installed angle and insulation thickness. Consequently, When Solar Window system is equipped with balcony window of Apartment, Annual heating and cooling energy of reference model was cut down at the average of $4.1kWh/m^2$ or 4.2%.

The aim of this study was to analysis the Heating/cooling performance of Solar Window System built in apartments. The solar window is the idea to integrate daylight as a third form of solar energy into a PV/Solar Collector system and allows more control due to the possibility to close the reflectors. However, there can be a conflict between the desire for on one hand daylight and view and on the other hand optimal energy conversion for the PV/Solar Collector system. The process of this study is as follows: 1) The Solar Window system is designed through the investigation of previous paper and work. 2)The simulation program(ESP-r, Therm5.0, Window6.0) was used in energy performance analysis. The reference model of simulation was made up to analysis energy performance on Solar Window system. 3)Selected reference model(Floors:15, Area of Unit:$148.5m^2$) for heating/cooling energy analysis, Energy performance simulation with various variants, such as U-value of Solar Window system according to its position and angle. Consequently, When Solar Window system is equipped with balcony window of Apartment, Annual heating and cooling energy of reference model was cut down about 5%~11%.

최근 건축물들이 100층 이상이 되는 Super Tall 추세로 증가되어가면서 자연스럽게 건축의장 부분에서도 변화의 바람이 불고 있다. 기존 건축물들을 구성하던 중량벽체를 대신하여 비내력벽 개념의 커튼월 시스템 사용으로 변화되어가고 있다. 그러나 커튼월 시스템은 건축물의 외부환경인 공기와 빛, 열 등의 요소들로 인해 부하가 많이 발생하며 특히 커튼월 외피부분에 발생되는 결로 문제가 심각해지고 있는 실정이다. 특히 국내 건설시장의 여건 상 건축물들의 밀집화로 인한 통풍량 및 일조량 부족으로 결로발생은 더욱 심각해지고 있다. 하지만 아직까지 결로발생을 검토하는 표준화된 절차가 정립하지 않은 실정으로 건설사업관리자를 위한 결로발생 검토프로세스 마련이 시급하다 할 것이다. 본 연구는 커튼월 시스템의 대표적 타입인 Unitized 시스템과 Stick 시스템 선정하여 동일한 온도에서 상대습도의 변화에 따른 결로 발생범위 및 온도분포를 비교 분석하여 커튼월 결로성능을 평가하고 향후 결로발생 검토프로세스 마련을 위한 기초자료를 제공코자 한다.
