This study assesses the performance of a Building Integrated Photovoltaic (BIPV) system using exergoenvironmental analysis method. The system has a peak capacity of 7.4 kW and has been successfully operated since its installation at Yasar University on 8 February 2016. In the analysis, we used the actual operational long-term data. Based on one uncloudy day selected from each month of the year, the exergy efficiency values based on the total and cell areas were in the range of 11.44-13.60, and 15.66-18.62, respectively while daily CO2 emission values for the selected days varied between 0.80 (June) and 1.34 kg CO2 (February).

In this paper, the effect of the Building Integrated Photovoltaic (BIPV) system on the building energy demand from the grid is investigated. The main load of the building is due to the Heating, Ventilation and Air-Conditioning (HVAC) equipment, and its load is highly correlated with the ambient temperature. Similarly, the BIPV system output is also dependent on the ambient conditions, and increases with higher solar irradiation but tends to reduce as temperatures decrease when all other factors are constant. BIPV systems, thus, have the potential to help building owners and operators, both from energy production and load reduction/shifting aspects. In this paper, we utilize a 12-month operational data from the BIPV system at Yasar University, and assess its performance from energy generation and demand reduction perspectives.
