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

BIPV is an architectural concept thatrelated to energy contribution. The system hasfunctions of producing electricity as well as buildingform giver. The effectivity of BIPV depends on solarradiation received. Meanwhile, the solar radiationreceived depends on numbers of solar receiving areaand environmental shading. Environmental shadingwill decrease the effectivity of BIPV. But, integratedconfiguration of folding-BIPV is expected to createmore numbers of solar receiving area. The integratedconfiguration of folding-BIPV will create optimumBIPV, both in electrical generation and building formgiver. Experiment to low rise office building intropical climate is done by giving folding treatment.The experiment also considers about environmentalshading. Evaluation is done by analyzing andoptimizing the numbers and uniformity of solarradiation received. Simulation with ARCHIPAK 5.1 isused as experimental research tool. The simulation isused to calculate annual radiation received (kWh/m²)from folding-BIPV configuration. Manual calculationis used to calculate total annual radiation received(kWh) and uniformity percentage. Gradient diagramis used to do the optimation. Result of this research isan optimation of electrical energy generation in lowrise office building which use folding-BIPV concep
