Impact of Facade based Building Integrated Photovoltaics on Indoor Thermal Conditions in Mumbai

摘要

Facade based building integrated Photo-voltaic(BIPV) is expected to form an integral part of the development of future urban buildings built with the aim of zero net-energy. Facade based BIPV can not only generate power but also be used to manage human comfort. Since the decision to include facade based BIPV has to be taken in the design phase of a building, it is important to know the thermal impact of BIPV on the indoor environment. The thermal impact varies with the transparency and technology of the BIPV. Currently, the performance of the BIPV is studied from the electricity generation and/or heating point of view. As of now, only one study is available in the literature, which compares two technologies of single transparency, their electricity generation potential, and their impact on indoor thermal comfort. The study presented in this paper focuses on data from two solar PV structures consisting of BIPV modules of six different technologies a-Si, CdTe, c-Si, CIGS, Micromorph, and Triple junction(Si-Ge) and four different transparencies. Each technology has varying transparencies from being opaque to semi-transparency of up to 40%. The experimental setup design to evaluate the performance of the BIPV and field measurement data are presented.
