Energy Performance Analysis of Air-Based BIPVT System Using Building Space

Efforts are continuing to reduce carbon emissions in various fields of society with the goal of becoming carbon neutral by 2050.Various studies have been conducted in the construction field to enhance the energy efficiency of buildings through the active introduction and utilization of new and renewable energy.Building-integrated photovoltaic thermal (BIPVT) systems are technologies that can be applied instead of building exterior materials and can generate heat and electrical energy from solar energy.Research has already been conducted on the advantages of BIPVT systems in terms of energy production compared to conventional building-integrated photovoltaic (BIPV) systems, which can only produce electrical energy.However, there have been insufficient studies comparing the performances of both systems simultaneously through experiments under the same weather conditions.In this study, an experimental model of a BIPV system with the similar structure as an air-based BIPVT system experimental model was produced with a new structure that can utilize space itself as a heat recovery device.Subsequently, the experiment was conducted simultaneously, and the thermal and electrical performance of the winter air-based BIPVT system was quantitatively evaluated by comparing it that of the BIPV system.
