Optimisation of Electrical Energy Generation for Low Rise Office Building with Folding-BIPV Concept

Abstract

BIPV is an architectural concept that related to energy contribution. The system has functions of producing electricity as well as building form giver. The effectivity of BIPV depends on solar radiation received. Meanwhile, the solar radiation received depends on numbers of solar receiving area and environmental shading. Environmental shading will decrease the effectivity of BIPV. But, integrated configuration of folding-BIPV is expected to create more numbers of solar receiving area. The integrated configuration of folding-BIPV will create optimum BIPV, both in electrical generation and building form giver. Experiment to low rise office building in tropical climate is done by giving folding treatment. The experiment also considers about environmental shading. Evaluation is done by analyzing and optimizing the numbers and uniformity of solar radiation received. Simulation with ARCHIPAK 5.1 is used as experimental research tool. The simulation is used to calculate annual radiation received (kWh/m²) from folding-BIPV configuration. Manual calculation is used to calculate total annual radiation received (kWh) and uniformity percentage. Gradient diagram is used to do the optimation. Result of this research is an optimation of electrical energy generation in low rise office building which use folding-BIPV concept.
