Techno-environmental assessment of outdoor glazing cover of a building with multi-passive solar systems

Abstract

With the expansion of urban areas and the growth of welfare levels, the energy consumption of buildings will increase in the next decades. Passive solar systems are one of the technologies to reduce energy consumption. In this paper, a building-integrated passive solar energy technology was studied in six different Scenarios including photovoltaic (PV) and Building Integrated Photovoltaic (BIPV) glazing windows, PV glazing façades, PV glazing double-skin façade, and simple double-skin façade. They were compared to the base model, respectively. It has been determined each scenario may be superior in one or more cases compared to other scenarios. Results show in the BIPV model, the inside temperature of the building was decreased by up to 1.3 degrees. The annual energy consumption for heating in the double-skin Scenario was reduced by about 17% compared to the base Scenario. The annual energy consumption for cooling in the building with PV glazing façade compared to the base scenario has decreased by more than 21%. Annually, CO2 emissions by 140%, and the cost of energy have decreased by 3493.4$ in building with PV glazing double skin facade and building with PV glazing facade, respectively. Finally, the shadow effect of the energy of the building is examined.
