Abstract

Increasing concern about the reduction of fossil fuel resources in today's societies has led to a greater tendency towards renewable energies. Therefore, solar energy is the most available renewable source. Most of the solar cells do not have the optimal efficiency. The most effective solution to solve this problem is to increase the efficiency of solar modules by combining them with other systems. One of these systems is the two-shell facade. By combining this system with solar panels, a new technology called photovoltaic systems integrated with the facade of the two building shells is introduced. The purpose of this research is to analyze several types of photovoltaic systems integrated with the facade of two building shells to observe its effect on the air conditioning load of the building and to optimize the parameters involved in this system for a hot and semi-arid climate. The results show that the temperature inside the building using the two-shell facade is two degrees Celsius lower than the simple case on average every month due to the greater heat transfer of the two-shell facade. The amount of cooling consumed inside the building is lower in the case of using the two-shell facade than in the simple case. In the summer, due to the intensity of solar radiation suitable for the city of Tehran and the lighting of the facade of two skins, the temperature inside the building rises and the need for more cooling is needed for proper air conditioning inside the building.
