“…Vats and Tiwari [107] have derived analytical expressions for room air temperature of BiSPVT and BiOPVT system integrated to the roof of a room and facade with and without air duct. It was found that the room air temperature for façade and roof in SPVT and OPVT systems with air duct is lower than without an air duct.…”

In this review, an attempt has been made to analyze passive solar heating and cooling concepts along with their effects on performance of a building's thermal management. The concepts of Trombe wall, solarium, evaporative cooling, ventilation, radiative cooling, wind tower, earth air heat exchanger, roof pond, solar shading for buildings, and building-integrated photovoltaic thermal (BiPVT) systems are extensively covered in this review. Comparison of results by various heating and cooling concepts has been made. It has been observed that direct heating through double-glazed window saves maximum conventional fuel for thermal heating during winter months. Further, an evaporative cooling is one of the best cooling concepts which is economical too in summer period. 2

“…Acosta et al [17] performed simulations on different rooms with four different skylight shapes to determine a suitable proportion and shape for monitor skylights. Comparative studies were carried out between building integrated semi-transparent photovoltaic thermal (SPVT) and opaque photovoltaic thermal (OPVT) systems, which were integrated into the facade and roof of a room with and without air duct for the cold climatic conditions in Srinagar, India [18].…”

“…Bonanno et al [11] proposed a novel neural network based technique for the modeling of electrical output characteristics of a solar cell using a radial basis function neural network (RBFNN). Vats and Tiwari [12] derived the analytical expression for room air temperature of building integrated semitransparent photovoltaic thermal (BISPVT) and building integrated opaque photovoltaic thermal (BIOPVT) systems each integrated to the roof of a room with and without air duct. The comparative study revealed that increase of air mass flow rate (0.85-10 kg/s) through duct increases the room air temperature from 9.4 to 15.2 0 C for SPVT roof for the given climatic and design parameters.…”

The aim of this paper is to maximize the overall exergy efficiency of single channel photovoltaic thermal module. The solar panel (PV module) generally gives electrical efficiency in the range of 7% to 12%, the rest energy being dissipated in the form of heat losses. To recover thermal energy from the module photovoltaic thermal system has been simulated. The analysis in this work investigates the influence of seven important parameters on the efficiency of PVT solar system which inter alia includes length and depth of the channel, depth of insulation, velocity of fluid in the channel, depth of the tedlar and glass, and temperature of the fluid at the inlet on the basis of which optimization of the exergy efficiency of the module is done. Attempt is made to develop mathematical model and optimize parameters of glazed hybrid single channel photovoltaic thermal (PVT) module. The relevant mathematical equations for the glazed hybrid single channel photovoltaic thermal module are derived and genetic algorithm (GA) used to optimize overall exergy efficiency of the module. Only the parameters that could physically be varied are included in this optimization analysis while naturally occurring parameters like ambient temperature and solar intensity which vary naturally are excluded from design parameters in the algorithm. During second stage following first optimization only one parameter is varied at a time in the course of analysis while others are kept constant at the previously obtained optimal value.
