研究目的
Studying the use of renewable energy technologies and alternatives; represented in new building integrated photovoltaics (BIPVs) technology that could be integrated within building skin to reduce energy demand.
研究成果
The study has shown a simulated comparison between two types of building integrated photovoltaics BIPV used, BISOL Premium BXO 365 Wp monocrystalline and BXU 330 Wp, polycrystalline. The studied types showed good performance, although they have been used in a limited area of only two facades. The BIPV could keep the building’s appearance unchanged, which represents an ideal retrofit strategy for keeping appearance in addition to reducing energy consumption. BIPV has a great potential in Egypt because of hot weather and difference in solar radiations between the north and south elevations. Computer analysis and simulation is currently having a great impact on the design decision. Simulation studies are pursued for understanding the building energy performance, electricity usage, and the energy potential of the building facade. Through the simulated study, the BISOL Premium BXO 365 Wp monocrystalline has proven to be more energy efficient and feasible because of a higher saving percentage in addition to a shorter payback period.
研究不足
The operational cost is the only factor calculated, however, the environmental costs should be investigated separately in future studies. The energy saved in both cases 1 and 2 is achieved by the partial replacement of only 7.13% of the total facade area.
