Abstract/Summary:


Shading systems improve building energy performance by controlling solar gains and natural lighting. Integrating photovoltaics opens new opportunities for building integrated photovoltaics by combining the benefits of adaptive shading with facade integrated solar tracking. Furthermore, it reduces the building energy demand and simultaneously generates electricity onsite. This paper presents a methodology for simulating the photovoltaic electricity production of a dynamic facade mounted PV system in combination with the energy consumption of a building through shading. The simulation is conducted within the parametric Rhino / Grasshopper environment using a high resolution radiation analysis for the calculation of PV electricity generation. Building energy analysis is conducted through DIVA / EnergyPlus. From this simulation we can determine the optimum hourly position and orientation of the PV panels, not only for optimal energy harvest, but also for the overall balance of the room.
