1. Introduction
Energy is considered as a prime agent in the generation of wealth and a significant factor in the economic development. Building integrated photovoltaic system, where photovoltaic cells are integrated within the climate envelopes of building and utilizing solar radiation to produce energy in the form of electricity. Building integrated photovoltaic systems replace part of conventional building materials and systems in the climate envelope of buildings, such as the roof and facades. To improve the performance of building, passive strategies such as energy efficient facade can be used. Improve façade and roof elements energy performance is the key as they are interface between the indoor and outdoor environments. Building integrated semitransparent photovoltaic (BISPV) started to become important in late 1990s. It has been considered as an attractive technology for building integration. Building integrated semitransparent photovoltaic is a new type of building material, which provides green energy as well as building preservation. Apart from generating electricity, BISPV modules can be customized in different dimension, thickness, shape and color. Semitransparent solar modules, BIPV applications demand flexibility in the PV module having both an aesthetic and functional role. BIPV systems can be installed as stand alone or grid connected systems. The types of systems utilized can consist of sloping roof systems, flat roof systems, façade systems wherein the modules replace large glass surface and integrated systems as façade accessories in which the modules are arranged as shading or solar protection systems. First generation (mono or poly crystalline) cells are usually integrated with roof covering, together with standard roof tiles. They have also been utilized as facades, replacing traditional glass as windows. Agrawal and Tiwari [1] developed analytical expression for room air temperature for an opaque type BIPVT system mounted on the rooftop of a building. Fung and Yang [2] developed the semitransparent photovoltaic module heat gainmodel and experimentally verified the thermal performance of semitransparent BIPV modules. Ordenes et al. [3] installed a PV system on rooftop of a building and concluded that it yields more energy than any of the vertical facade. They observed that more than 45% of energy will be produced on the rooftop portion of PV installation. Oh et al. [4] developed a costeffective method for integration of existing grid with new and renewable energy sources on public buildings in Korea. Proper combination of new and renewable energy sources is suggested by detailed numerical calculation based on the hourly energy demand pattern data obtained from field studies for the buildings. Wu et al. [5] evaluate performance of heat pipe photovoltaic/thermal (PV/T) hybrid system and found the overall thermal, electrical and exergy efficiencies of the heat pipe PV/T hybrid system corresponding to 63.65%, 8.45% and 10.26%, respectively can be achieved under the operating conditions. The varying range of operating temperature for solar cell on the absorber plate is less than 2.5 °C. The heat pipe PV/T hybrid system is viable and exhibits the potential and competitiveness over the other conventional BIPV/T systems. Koyunbaba et al. [6] developed the simulation model with experimental results of a model BIPV Trombe wall built in Izmir, Turkey and they found that 10% of solar radiation transmittance has been supplied by using a Semi-transparent a-Si solar cell. Thus, thermal energy input to the system increases compared to other BIPV systems. Meanwhile, the experimental daily average electrical and thermal efficiency of this system can reach 4.52% and 27.2% respectively. Chandrasekhar et al. [7] concluded Flat solar photovoltaic (PV) modules are widely being used in domestic and industrial buildings for meeting the electric power demands. Higher operating temperatures of these PV modules result in lower electrical power yield and conversion efficiency. Shan et al. [8] reviewed the photovoltaic–thermal (PVT) solar collector system using various working fluid via dynamic simulation. The performance of a hybrid PVT collector using refrigerant as working fluid was evaluated and analysed for the typical weather condition in Nanjing, China. The simulation results showed the influence of the meteorological parameters and the evaporating temperature on the photovoltaic and thermal performance of the hybrid photovoltaic–thermal collector. Shan et al. [9] carried out Dynamic performances modeling of a photovoltaic–thermal collector with water heating in buildings. The results indicated that the less series-connected PV modules, the lower inlet temperature of water and the higher mass flow rate of water resulted in the high photovoltaic efficiency. Vats et al. [10] studied the effect of packing factor of semitransparent photovoltaic (PV) module integrated to the roof of a building, on the module and room air temperature, and electrical efficiency of PV module. It has been observed that the decrease in the temperature of PV module due to decrease in packing factor, increases its electrical efficiency. It is also found that the decrease in packing factor increases the room temperature. Maximum annual electrical and thermal energy is found to be 813 kWh in HIT and 79 kWh in a-Si PV module respectively with packing factor of 0.62. Dubey et al. [11] analysed energy and exergy of PV/T air collectors connected in series. It is found that the collectors fully covered by PV module and air flows below the absorber plate gives better results in terms of thermal energy, electrical energy and exergy gain. Physical implementation of BIPV system has also been evaluated. If this type of system is installed on roof of building or integrated with building envelope will simultaneously fulfil the electricity generation for lighting purpose and hot air can be used for space heating or drying. Kılkıs [12] studied energy consumption and CO2 emission responsibilities of terminal buildings. As a result, this study has exemplified the essential boundaries for energy consumption analysis envelope for an airport terminal building and its true emissions responsibility. Sarhaddi et al. [13] studied the exergetic performance of a solar photovoltaic thermal (PV/T) air collector. It is observed that the modified exergy efficiency obtained in this paper is in good agreement with the one given by the previous literature. It is also found that the thermal efficiency, electrical efficiency, overall energy efficiency and exergy efficiency of PV/T air collector is about 17.18%, 10.01%, 45% and 10.75% respectively for a sample climatic, operating and design parameters. Agrawal and Tiwari [14] Performed an analysis of the building integrated photovoltaic thermal (BIPVT) system fitted as rooftop of a building to generate electrical energy and also to produce thermal energy for space heating. The results indicate that although the mono-crystalline BIPVT system is more suitable for residential consumers from the viewpoint of the energy and exergy efficiencies, the amorphous silicon BIPVT system is found to be more economical. Buker et al. [15] analysed performance evaluation and techno-economic of a novel building integrated PV/T roof collector. The experimental values indicate that water temperature difference could reach up to 16 °C, and the system would achieve up to 20.25% overall thermal efficiency. The energy and exergy analysis is performed to observe the increase in energy and exergy efficiencies due to the implementation of concealed heat extraction component. Vats, Tiwari [16] evaluated the Performance of a building integrated semitransparent photovoltaic thermal system for roof and façade. It is observed that there are maximum (18 °C) and minimum (2.3 °C) rise in room air temperature for semitransparent photovoltaic thermal (SPVT) roof without air duct and opaque photovoltaic thermal (OPVT) facade with air duct respectively. The electrical and exergy results presented in this study are in good agreement with the experimental results of Sudhakar and Srivastava [27]. Shukla et al. [28] evaluated exergy efficiency of amorphous and polycrystalline PV module throughout the day. The energy efficiencies of both the modules are found to be always higher than that of exergy efficiencies and power conversion efficiencies. A number of research studies have been conducted on the energy and exergy evaluation of BIPV systems. This research paper aims at determining the performance of building integrated semitransparent photovoltaic (BISPV) modules for roof and facade Solar radiation intensity on BISPV modules surfaces is an essential parameter for assessing energy performance of the BISPV modules. Performance analysis through energy and exergy efficiencies and evaluation of electrical and thermal energy output of BISPV system for roof and façade of building has been presented in this paper.
