As Building Integrated Photovoltaic(BIPV) system replaces the conventional building finishing materials with PV modules, two function of electricity generation and building envelope can be expected. Therefore BIPV can be a good alternative technology for the 21 century environment-friendly buildings. The objective of this paper is to develope BIPV modules for a commercial buildings of which structure is mainly light-weight, curtain wall system. Two types of module are developed for a opaque part and a transparent part of building envelope. Current technology level and market status of Korea determines the configuration of developed BIPV modules. Architectural considerations for the integration of PV module to building envelope such as building structure, construction type, safety, regulation, maintenance etc. have been carefully reflected from the early stage of BIPV module design. Especially the survey result of current building envelope materials determines the size of unit BIPV modules and a unique cladding method for PV module installation is developed. Trial product of BIPV modules and cladding hardwares are manufactured and sample construction details for a demonstration building are proposed.

Recently, the cases of BIPV(Building-integrated Photovoltaic) have been increased with interest in renewable energy application for buildings. PV System in building can perform a variety of roles as an energy supplier, exterior materials, aesthetic element and etc. To apply PV modules in buildings, various factors should be considered, such as the installation angle and orientation of PV module, shading, and temperature. The temperature of PV modules that are attached to building surfaces especially is one of the most important factors, as it affects both the electrical efficiency of a PV module and the energy load in a building. BIPV modules designed as finished material for spandrels are presented in this paper. The purpose of this study is to analysis on the thermal performance characteristics of BIPV modules. This study dealt with different types of BIPV modules depending on the backside material, such as clear glass and backsheet. The analysis of monitoring data shows that the PV module temperature was closely related to the solar radiation on the BIPV module surface, and the BIPV used at the backside also had an effect on the PV module temperature that in turn determines its thermal performance.

BIPV is applied to buildings in various forms. However, there are some aspects of consideration in applying PV systems in buildings, such as attaching methods, PV electrical efficiency, appearance and so on. BIPV can be installed on curtain wall spandrel as finishing material, which may combine with insulation. The thermal characteristic of spandrel with BIPV has rarely been studied; the temperature of air space between PV module and insulation layer affects both the electrical behavior of PV module and the energy load in a building. This paper aims to analyse the temperature variation of the layers in BIPV spandrels. In this paper, the temperature of layers, including the air space and PV module, was measured for three different type of BIPV applications on spandrel. The results show that the temperature of air layer for the spandrel with G/G(2) type BIPV module on October was the highest among other months.

The integration of PV modules into building facades or roof could raise PV module temperature that results in the reduction of electrical power generation. Lowering operating temperature of PV module is important in this respect, and PV module temperature should be considered more accurately, for building-integrated PV(BIPV) systems in predicting their performance. This paper describes a BIPV solar roof design and verifies its performance through experiment In relation to the effect of ventilation in space between PV module and roof surface. The results showed that the ventilation in the space had a positive effect in lowering the module temperature of the BIPV solar roof that enhanced the performance of its electricity generation.

Building integrated photovoltaic (BIPV) system operates as a multi-functional building construction material. They not only produce electricity, but also are building integral components such as facade, roof, window and shading device. On the other hands lots of architectural considerations should be reflected such as Installation position, shading, temperature effect and so on. As PV modules function like building envelope in BIPV, combined thermal and PV performance should be simultaneously evaluated This study is on the combined thermal and PV performance evaluation of BIPV modules. The purpose of this study is to investigate a temperature effect of PV module depending on the ventilation type of PV module backside. Test cell experiment was performed to identify the thermal and power effect of PV modules. Measurement results on the correlation of temperature and power generation were obtained. Those results can be utilized for the development of optimal BIPV installation details in the very early design stage.

BIPV system not only produces electricity at building, but also acts as a material for building envelope. Thus, it can increase the economical efficiency of PV system by saving the cost for building materials. Bifacial solar cell can convert solar energy to electrical energy from both sides of the cell. In addition, it is designed as 3 busbar layout which is the same with ordinary mono-facial solar cells. Therefore, many of the module manufacturers can easily use the bifacial solar cells without changing their manufacturing equipments. Moreover, bifacial PV system has much potential in building application by utilizing glass-to-glass structure of PV module. However, the electrical generation of the bifacial PV module depends on the characteristics of the building surface which faces the module, as well as outdoor environment. Therefore, in order to apply the bifacial PV module to building envelope as BIPV system, its power generation characteristics are carefully evaluated. For this purpose this study focused on the electrical performance of the bifacial BIPV system through the comparative outdoor experiments. As a result, the power generation performance of the bifacial BIPV system was improved by up to 21% compared to that of the monofacial BIPV system. Therefore, it is claimed that the bifacial BIPV system can replace the conventional BIPV system to improve the PV power generation in buildings.

Recently, BIPV system which is good enough for maintenance and functions with the shading system is being used. However BIPV system with the shading system is different from existing PV module because of using flexible PV module. Prior to the application of the BIPV system, the clearness index was calculated by Erbs et al.(1982) and analyzed for the amount of electric power generation of sky irradiance with measured data. To predict electric lighting energy savings in daylit space, electric lighting power savings with amount of PV module electric power generation was compared by using Relux 2010 software in this study.
