The types of installation of the photovoltaic system applied to domestic residential buildings are classified as follows: Mounted modules with air circulation, semi-integrated modules with air duct behind, integrated modules with fully insulated back. In order to study generation characteristics of PV system, we verified the validity of interpretation program based on long-term measurement data of demonstration house installed in BAPV form and also analyzed the generation characteristics and performance of each installation type. The results are as follows. First, the RMSE of amount of generation and simulation according to annual daily insolation of demonstration system located in Daejeon was 0.98kWh and the range of relative error of monthly power generation was -5.8 to 3.1. Second, the average annual PR of mounted modules was 82%, semi-integrated modules 76.1% and integrated modules 71.9%. This differences were attributed to temperature loss. Third, the range of operating temperature of annual hourly photovoltaic modules was –6.5 to 61.0°C for mounted modules, –6.0~73.9°C for semi-integrated modules and –5.5 to 88.9°C for integrated modules. The temperature loss of each installation type was –14.0 to 16.1%, –13.8 to 21.9%, and –13.6 to 28.5%, respectively.

As an empirical study for the building-integrated photovoltaic system, the efficiency of several photovoltaic panels with the inclination angle of 17° constructed on the roof of a building was studied. The photovoltaic panels used in this study were crystalline Si, thin-film Si, and thin-film Si modules. The annual average operating time of the panels on the north face was rather low and the annual average operating time of the panels on the south face was rather high. The maximum operating time of the module was obtained at the case of crystalline Si module on the south face (3.5hr), and the annual average operating time of the crystalline Si module on the south face and the north face was 2.99hr. When the module temperature was high (summer season), the operating time of the thin-film module was high. However, when the module temperature was low (winter season), the operating time of the crystalline Si module was high. 태양전지를 이용한 태양광발전은 화석연료를 사용하는 다른 발전방식에 비하여 대기오염이나 소음의 발생이 없는 친환경적인 에너지 생산상식이다. 태양광 발전에서 모듈의 종류 및 시공방법은 발전성능 뿐만 아니라 건물의 특성 및 입지 기후조건과 연계하여 고려해야 한다. 건물일체형 태양광 발전의 실증연구로서, 건축물의 남향 및 북향 옥상면에 경사각 17°를 따라 태양광 발전 모듈을 시공하여 그 발전효율을 평가하였다. 실증 연구에 사용된 발전 모듈은 결정질 태양전지, 박막 Si 태양전지, 박막 Si 태양전지 등 3종류로 하였다. 북향으로 시공된 모듈의 경우 일일 발전시간 평균치는 다소 낮게 나타났으며, 남향으로 시공된 모듈의 경우 일일 발전시간 연간 평균치는 다소 높게 나타났다. 최대 발전시간을 나타낸 것은 남향으로 설치된 결정질 Si 모듈이며 (3.5시간), 남북향 발전시간 평균값에서도 결정질 Si 모듈이 가장 우수하였다 (2.99시간). 박막모듈에 비해 결정질 모듈의 발전시간이 더 길게 나타났다. 모듈온도가 상승한 하절기에는 박막모듈의 발전성능이 우수하고, 겨울철에는 결정질 모듈의 성능이 우수하였다.

현대디자인은 대량생산과 대량소비를 통해 소비적인 삶의 방식을 촉진하고 영리창출을 위한 경제적 도구로 간주되어왔다. 그러나 화석에너지를 활용한 생산방식으로 인한 이산화탄소의 배출로 환경오염 문제가 심화되면서 융합연구를 통한 지속발전 가능한 디자인에 대한 관심이 높아지고 있다. 본 연구에서는 지구오염의 주범인 이산화탄소의 약 40%가 발생하는 건물을 지속발전 가능한 디자인의 대상으로 정하였다. 또한 한국적인 친환경건물의 롤모델을 제시하고자 건물일체형 풍력과 태양광 하이브리드 에너지시스템을 갖추고, 닫힌 공간과 열린 공간이 공존하며 수평확장과 수직상승이라는 건물의 구조적인 특성과 유사한 ‘ㅍ(피읖)’과 ``ㅂ(비읍)``, ``ㅅ(시옷)``, ‘ㅁ(미음)’, ‘이응(ㅇ)’ 등의 한글자소를 적용한 건물 디자인을 제안하였다. 그리고 동시대 기술로 건축이 가능하고 아름다운 친환경건물 디자인을 위해서 디자인팀, 기계공학팀 그리고 건축공학팀의 융합연구로 진행하였다. The contemporary design has been regarded as a tool for economic advance, it promotes consuming life style as well as profit creation via mass production and mass consumption. However, as the environmental contamination gets intensified by carbon dioxide emissions from a fossil energy-based production method, corporations and designers are now showing interest in sustainable design through convergence research. In this study, buildings which are responsible for nearly 40% of greenhouse gas emissions were selected as a subject for sustainable design. In addition, in order to suggest a role model for Korean eco-friendly building, the study worked on a building-integrated wind power and photovoltaic hybrid energy system. A Design motif of the Hangeul consonant, ``pi-eup(ㅍ)`` applied to the building. Its features are the coexistence of an enclosed and open space, and the horizontal and vertical extension which are considered structurally similar to those of the building. Also, other Hangeul consonants like ``bi-eup(ㅂ)``, ``si-ot(ㅅ)``, ``mi-eum(ㅁ)``, ``yi-eung(ㅇ)`` and others are used too. Add to that, for a beautiful green design that could be built with existing technologies, the study conducted convergence research in cooperation with a design team, a mechanical engineering team and an architectural engineering team.

Solar power systems are the most commonly used renewable energy systems for energy self-sufficiency in buildings. In particular, bifacial photovoltaic modules for solar power generation have been researched for their optimal application, as they can generate electricity from two sides using only a single frame. In addition, because the price of a bifacial photovoltaic module is approximately 20% higher than that of a single-sided module, installing bifacial photovoltaic modules in suitable locations on buildings can be economical. To date, most studies have primarily focused on how to increase the amount of power generation from rear cells by arranging materials with high reflectivity on the floors of buildings. In point of fact, when bifacial photovoltaic modules are arranged in an east-west orientation, the maximum amount of power can be obtained in the mornings and afternoons. However, when these modules are installed in buildings in this orientation, a shadow is produced on the building surface according to the trajectory of the sun. In addition, when photovoltaic modules are used in the building envelope, the amount of power generation is often reduced because of this shadow. Nevertheless, even when considering this reduction in power generation, if the total power generation is higher than when photovoltaic modules are installed only vertically, the self-sufficiency rates of buildings can be improved. In this study, the shadow of a bifacial photovoltaic module was simulated using vertical photovoltaic modules to consider the possibilities of architectural application of bifacial photovoltaic modules.

The Amid booming photovoltaic(PV) industry, building integrated photovoltaic(BIPV) is one of the best fascinating PV application technologies. To apply PV in building, variable factors should be reflected such as installation position, shading, temperature effect and so on. Especially a temperature should be considered, for it affects both electrical efficiency of PV module and heating and cooling load in building. Semi-transparent PV modules designed as finished material for spandrels are presented in this paper. The temperature variation of the modules with and without air gap and insulation were compared and analyzed. The results showed that the module with air gap and insulation has a much larger temperature variation than another transparent module. The temperature of the module reached by 55degree C under vertical irradiance of lower 500W/㎡. And the temperature difference between these modules was about 15degree C. To analyze the output performance of module according to temperature variation, separate module was manufactured and measured by sun-simulator. The results showed that 1 degree temperature rise reduced about 0.43% of output power.

A building-integrated photovoltaic (BIPV) system is a renewable energy system that generates electricity and functions as a building envelope for zero energy buildings (ZEBs). BIPV can be applied to roofs, façades, and window systems. In particular, a semi-transparent BIPV applied to window systems is designed to satisfy the thermal performance requirements of national standards. The solar heat gain coefficient (SHGC) is used to estimate the solar radiation that passes through the glass relative to the amount of solar radiation hitting the glass. The SHGC of a semitransparent BIPV system change with the PV cell ratio, design, and electrical performance of the system. However, studies on the performance evaluation of SHGC for semitransparent BIPV systems are scarce. In this study, a method for evaluating the SHGC of a semitransparent BIPV system was investigated. The results indicate that SHGC values for the semi-transparent BIPV system should be studied for different operating conditions as indicated by maximum power point (MPP) and open circuit (OC) values. This is because the SHGC of the system changes with the power generation of the PV cells.

The use of BIPV system is used as building exterior material, which reduces the material cost in construction and contributes to the building value by using environmentally friendly building exterior elements. Further, no additional installation site is required, and power loss such as power transmission can be minimized due to the same power generation site and consumption site. However, the contents of the BIPV frame structure and the performance including the electric wiring are not included in the standards and guidelines. In this paper, the guidelines for the construction direction (Structural and electrical equipment, etc.) of the BIPV system for the safety standard of the domestic BIPV installation are presented.
