Building Integrated Photovoltaic (BIPV) is one of the best ways to generate electric power using the solar energy, which is clean and inexhaustible energy resources. The most of BIPV modules have the form of GtoG (Glass to Glass) photovoltaic in building applications. Degradation leading to failure in photovoltaic modules is very important factor in BIPV modules. This paper analyzed the performance of various BIPV modules through outdoor exposure tests. Performance of three BIPV modules(c-Si type, a-Si type and DSSC type) with three installation angles influenced by sun light, outdoor temperature, and wind velocity was monitored and analyzed. As a result, c-Si type BIPV module outperforms other BIPV modules(a-Si type). In terms of power efficiency of the module, the installed angle of 45° is better than others(90 degree, 0 degree). In addition, more realistic data of various BIPV system performance could be available through the field test and integrated building test. In this study, relationship of the BIPV system is identified module’s installation angle, power generation, architectural performance, etc.

As climate change begins to affect every corner of the world, renewable energy becomes increasingly important. However, although the BIPVsystem gets more attention with improved efficiency, its aesthetical design integration is still far behind. Therefore, first, this work analyzesthe aesthetic design aspects of BIPV integrated design through previous studies and IEA studies. Secondly, 12 elements of BIPV systemdesign aesthetic evaluation are derived. Third, these elements are applied to five selected cases to explore the improvement of aestheticdesign elements for BIPV integrated design. In conclusion, the aesthetic elements of BIPV seen through the cases were expressed in anintegrated design as an architectural language based on technology. Among them, color, shape, pattern, composition, and harmony were foundto be important aesthetic considerations of BIPV integrated design. 전 세계적으로 환경문제가 심각해지면서 재생에너지의 중요성이 높아지고 있다. 특히 효율성과 경제성이 향상되면서 BIPV 시스템에 대한 관심도 높아지고 있다. 그러나 BIPV 시스템의 심미적 설계 통합이 여전히 부족하며 이에 대한 연구는 활발히 진행되지 않고 있다. 따라서 본 연구는 첫째, 선행 연구를 통해 BIPV 시스템의 통합 설계를 위한 심미적 설계 요소를 추출하고 분석한다. 둘째, 추출된 12가지 심미적 설계 요소를 기반으로 이를 BIPV 모범 사례에 적용하여 건물일체형태양광(BIPV) 통합설계를 위한 심미적 디자인 요소에 관한 개선 방안을 모색하였다. 결론적으로, 사례들 통해 본 BIPV의 심미적 요소들은 기술을 기반으로 한 건축 언어로 통합 설계로 표현되었다. 그 중 색상, 형태, 패턴, 구성, 조화가 BIPV 통합 설계의 중요한 미적 고려 사항임을 알수 있었다.

Assome of its components are made of combustible materials, it is necessary to evaluate the risk of fire. In this study, therisk of fire before and after BIPV installation was compared through fire simulation using the PyroSim program. Prior tothe simulation, a BIPV combustion characteristic database was established via a cone calorimeter experiment with a BIPVsystem panel, and the results were analyzed through a fire simulation using these experimental values as input values. Thefire risk evaluation confirmed that when BIPV was installed, the fire propagation due to vertical diffusion was fast. Additionally, the amount of heat and smoke emitted increased, resulting in an increase in the risk of fire by 54.94% basedon the center of the building at 805 s. Therefore, it is expected that the results of this study will contribute to securingthe reliability of evacuation and manual measures for people in BIPV-installed buildings as well as improve fire safety.

BIPV(Building Integrated Photovoltaic System), which is one of the new and renewable energy, does not require additional installation space, because the photovoltaic module can be applied to the roof or wall. The application of BIPV continues to increase due to its advantages not only the original function of the electric energy production but also the reduction of the finishing materials in buildings. However, previous research focused on BIPV applied to the small buildings. The study on application of BIPV to the external environment conditions in skyscraper has not been developed yet. This study reviewed the issues such as design, construction and maintenance that may occur when BIPV was applied to the skyscraper in a traditional way. What is more, it is a basic study on the direction of BIPV application in order to save energy in skyscraper. Thereafter, this development target to implement both energy production and energy saving when BIPV is applied to skyscraper.

The BIPV system must be designed to reflect the architectural and electrical characteristics simultaneously because it replaces the role of the exterior material of the building, which makes it difficult to design the BIPV. The thin film type BIPV module has an electrical characteristic that the open voltage is higher and the short circuit current is lower than that of the crystalline type BIPV module. However, there are many differences in the design of the array, the collector distribution board, and the inverter in the system configuration since the crystal type BIPV module has the opposite feature. In this study, a crystalline BIPV module and a thinfilm BIPV module were applied to actual buildings. As a result, the elements to be considered in designing BIPV system were derived, and the architectural and electrical characteristics were mutually analyzed.

As the number of buildings that use the transparent permeation materials as the outer wall is on the increase, the coming amount of the light rays is a lot, and thus the increase in the cooling load and the radiant heat of high temperature may cause the residents to discomfort. In order to reduce such influences, this paper analyzed the installation effects of the sunshade BIPV. The inner temperature of the room installed the sunshade BIPV or otherwise was measured, and compared and analyzed the effects of reducing the cooling load by the incoming light rays. The sample space of the third floor of S university installed the sunshade BIPV has two rooms on the same conditions, and for five sunny days selected in August, the researcher measured the air temperature and the temperature of the fittings with closing the windows to minimize the movement of air without operating the coolers. The maximum cooling load measured by the incoming light rays in the room where the sunshade BIPV was not installed was examined as 459.13kcal/h. It can be understood as the effect of reducing the cooling load according to the incoming rays of the room with sunshade BIPV. Even though the effect of cooling load reduction is not so great in a room, the total reduction in cooling room for the 32 rooms installed the sunshade BIPV was estimated to be 40442.27kcal/day, which will be able to bring the maximum reduction effect of 17.lkW in energy and reduce the investment cost owing to the reduction in cooling load when initially designing the building.
