a b s t r a c tThis article presents the state of the knowledge on the thermal analysis of double skin facades with integrated photovoltaic (PV) panels called the Building Integrated Photovoltaics (BIPV) in terms of the published studies carried out on these systems. The idea of integration of the PV panels by replacing building elements, increase the prospects of the renewable energy systems. Taking also into account the need to use more renewable energy systems in buildings, the investigation of the BIPV systems to improve their performance is of a great importance. The literature studies are separated into experimental and theoretical for naturally ventilated systems and mechanically ventilated with external means e.g. fan use. It is concluded that most researchers studied the systems with mechanical ventilation rather than the systems with natural ventilation because the latter are more complex in terms of the air flow behaviour in the air duct. Additionally, various researchers proposed Nu number correlations and convective heat transfer correlation under several assumptions and conditions every time, for different range or Ra number which are presented and compared in this paper.

“…In summer, the upper opening (5) and the lower opening (9) are closed while the upper shield (1) and the lower shield (4) are opened so that the air passage (6) and the outdoor air forms a loop; thermal siphoning causes the air flowing upwards from bottom in the passage, bringing away the heat absorbed by the phase-change heat-storage wall (7,8) and the photovoltaic glass (2), and thereby the photovoltaic cells can be cooled down to some extent and overheating of the room in summer can be prevented. In addition, when the air temperature in the passage rises to the phase transition temperature of PCM, the PCM undertakes phase change process; the temperature can hardly rise as the PCM absorbs a significant amount of heat in the phase change process, and thus the rise of air temperature in the passage is inhibited and meanwhile, the photovoltaic cells and the building walls can be cooled down to some extent.…”

“…The change in electrical efficiency by surface temperature of the PV module had been interpreted and the electrical power rate of the PV module had been designated. Zogou and Stapountzis [8] studied the flow and heat transfer of a BIPV/air wall system for building application. In this work, the results from flow visualization and hot wire anemometry measurements performed on the basic structural module of a double-skin photovoltaic (PV/T) façade were discussed.…”

This paper proposes a novel PV-Trombe wall system combined with phase-change material, which is named as PV-PCM-Trombe system. The work mainly experimentally studies the effectiveness and characteristics of using phase change materials to improve the overheating problem of PV-Trombe wall in summer. Through experiments, the photoelectric performance of the system using phase-change board surfaces with and without a matte black paint lacquer are compared; moreover, the influence on thermal environment of building is evaluated. The results indicate the PV-PCM-Trombe wall system shows an effective cooling effect on PV cell in both experiments and that the surface lacquer coating treatment of PCM plates affects little the photoelectric performance of the system and can reduce the working temperature of PV cell.

“…This technique is explained in more detail in the following sections. Few PIV studies have been conducted for closed cavity air circulation (Corvaro et al, 2011;Sanjuan et al, 2011;Zogou and Stapountzis, 2012), and a comprehensive study concerning simultaneous airflow around and within the cavity is rarely addressed.…”
