Efficiency of BIPV measured by comparing electricity output and electricity demand. Electricity output generized by BIPV depends on the amount of solar radiation received by PV panel. Some factors that affect the amount of radiation received are the tilt angle and the orientation angle of PV panel. This research try to rise electricity output by collaborating this factor with orientation principle in folding concept. The collaboration results in bigger surface area to receive radiation. Meanwhile, the reducement of electricity demand will be described in relation with users behaviour, both individual behaviour and communal behaviour. As the object taken in this research is an office building, communal behaviour will take more impact to reduce energy demand. Policies and strategies related to energy efficiency made by central operational management in office building will control communal behaviour.
