BIPV (Building Integrated Photovoltaics) refers to the application of PV (photovoltaic) in which the system as well as having the function of producing electricity, also takes the role of building form and element. One of interesting solution from BIPV application is the use of huge vertical facade in mid and high-rise building at urban area. In fact, the use of vertical facade is associated with the availability of huge vertical area compared to horizontal area (roof). The vertical installment might minimize radiation supply, but huge facade is expected to compensate power reduction. Electricity output generized by BIPV depends on the amount of solar radiation received by PV panel. There are some factors affect the amount of radiation received. One of them is the tilt angle and the orientation angle of PV panel. Higher electricity output are tried to be reached by collaborating those factor with orientation principle in folding concept. The collaboration results in bigger surface area to receive radiation. The purpose of this research is to find out the optimum folding wall-BIPV configuration. This purpose will be achieved through two steps. First, comparing annual radiation received by folding wall-BIPV configuration and flat wall-BIPV. Second, optimizing annual radiation received by folding wall-BIPV configuration. Experiment with simulation as it tools will be used as research method to get the optimal configuration of Folding Wall-BIPV.
