  • This paper discusses thermal and ventilation performance which might be caused by the adoption of one of specific building facade techniques, Double Skin System(DSS). One building with a prototypical DSS was selected and systematically investigated through field monitoring and computer simulation techniques. A network model of ventilation was successfully made using COMIS to evaluate ventilation performance of the system which can hardly be done by field measurements. Various operating conditions of air conditioning on/off and window opening were implemented in this type of building. Through the appropriate operation of the DSS in summer, simulation-based and experimental results implicate that it can lead to cooling energy savings.

  • The apartment will be much more convenient than the other one in the application of green technologies, providing the merits by mass production. For example, pre-manufactured building materials can be effectively adapted to the formation of buildings. Recently, the form of double-enveloped window system has been developed for the purposed of minimizing energy loss occurred around windows. On the other hand, the expansion of balcony area was legalized and thus, a visual buffer area does not exist any more. All-glass window wall on apartment houses without a balcony produces pretty harmful area with direct sunbeam. A various types of glass can be applied to the window system and it plays a critical role in the determination of inner visual environment. For the purpose of verifying the potential of its daylighting, a mock-up model has been constructed and tested. The refurbished version of conventional window shows its illuminated characteristics. Clear and Low-e glass have been adapted for window area and daylighting ratio has been compared in both test cells.

  • The annual mean temperature of South Korea has risen by $1.3^{\circ}C$ for last 100 years by urbanization and industrialization. Especially, the frequency of unusual hot weather in summer increases for a long time and the frequency of unusual cold weather in winter clearly decreases. In recently, The considerable portion of curtain wall system is appled to building skin in domestic. As related to this, the Korea Institute of Construction Technology devised the box typed double skin facade(It is occasionally called as FDFS : Functional Double Facade System) as an alternative that reflects the distinctive local climate and saves cooling energy. Two mock-ups($49m^*4.9m$) applied to single skin(curtain wall) and double skin each were monitored under the outdoor condition. Therefore, the characteristics of natural ventilation and cooling energy consumption of each window had been analyzed in real time. The results of this study are summarized as follow, Analysis of the experiment on an air conditioner: the indoor temperature of the chamber with FDFS is lower than that of the chamber with single skin facades by $3{\sim}6$ degrees(C). A temperature variation of about $1{\sim}2$ degrees between the 0.2m and 1.7m height of the mock-up occurs in FDFS, while that of about maximum 7 degrees occurs in single skin facade at noon with abundant intensity of solar accident. Also, 67 percent of energy consumption for air conditioning has been saved.

  • KNU 식물공장 모델의 냉난방 에너지 부하를 DesignBuilder를 이용하여 해석하였다. 실내설정온도, LED 보광주기, LED 보광량, 유리외피의 구조에 따른 에너지 소모량을 분석하였다. LED 보광이 없는 식물공장의 실내설정온도를 상추의 적정 생육온도인 $20^{\circ}C$를 중심으로 $15^{\circ}C$, $25^{\circ}C$로 변화시키면서 일정온도로 유지하는데 필요한 연간 냉난방부하를 분석하였다. $15^{\circ}C$일 때 냉방부하, $25^{\circ}C$일 때 난방부하가 가장 크게 나타났다. 상추 재배에 필요한 LED 보광 적용 시 난방부하는 감소하지만 냉방부하가 약 6배 증가한다. 또한 LED 보광 시 주간보다는 야간보광이 냉난방부하 감소에 유리한 결과를 주었다. 식물공장 외피가 냉난방부하에 미치는 영향을 비교하기 위하여 다섯 가지 종류의 외피를 적용하여 계산하였다. 이중창호의 열관류율이 작을수록 식물공장의 난방부하는 감소하고 냉방부하는 증가하였다. 재배할 작물의 적정생장온도 설정, LED 및 재배설비의 내부발열량에 따른 적절한 외피선택, 다양한 패시브 및 액티브 에너지 절감기술의 적용으로 냉방부하를 감소시키는 것이 식물공장 운영에 중요한 요소로 판단된다.

  • Regarding to the Domestic housing politics to improve residing environment and effective use of country land, apartment buildings have been constructed since early of 1970s. Now apartment is taking over 50% out of entire housing in Korea. In the view point of PV application to the apartment, PV has amny advantages because of the wideness of out-walls and high floors building in APT. Therefore, if APT could use the electricity produced by BIPV, we can solve more easily environment and energy problems caused by housing. The research conclusion by analysing conditions and application method to introduce BIPV application to APT in near future is as below. -The out look of APT has been developed periodically and recently gable roof or canopy is popular which PV installation is more favorable. -For Balcony part with double skin facade sassy window, It has a preferable condition to install on the wall depending on the window direction. -In case of shorter distance between buildings due to high ratio of outside measurement, it is more desirable to install PV on the roof than on the wall of Apartment by considering low solar altitude. -Also depending on the direction of APT building, it is more effective and productive in electricity in the broad surface of side wall of APT. -In case of superhigh floor APT where facade system is mostly double skin facade of curtain wall system, PV module can replace the traditional curtain wall and will reduce architectural materials and obtain various out look design thereof.

  • Double skin facade(DSF) ventilated by fans consists of a normal external and an internal envelope. In this glass layer, the installed fan replaces an air inlet for the control of air flow through the cavity. The purpose of this paper is to investigate physical theory and to analyze the applicability of fans installed in a DSF. The experiment was conducted in 2 rooms. One room has a DSF with installed fans and the other one has a typical window. The room ventilated through a DSF which fans are installed was always kept warmer than the other room, ventilated directly from the outdoors. The average increase of the supplied air temperature through the DSF ventilated by fans was $6.54^{\circ}C$ at 78CMH, $6.2^{\circ}C$ at 95CMH, and $3.7^{\circ}C$ at 120CMH. As a result, the DSF with installed fans was appropriate for installation in rooms. It supplies outdoor fresh air heated through a cavity and ventilates a constant air volume.
