Static Optimization Simulation of Vertical Photovoltaic Louver System for Office Buildings in Guangzhou City
Photovoltaic shading devices(PVSDs)can effectively achieve near-zero energy consumption in buildings by combining external shading and photovoltaic power generation modules,reducing indoor cooling loads while providing renewable energy.Vertical PV louvres can avoid the self-shading effect of horizontal louvres in PV shading devices,making fuller use of solar radiation and extending the service life of PV modules.This paper analyses the energy performance,lighting performance,and carbon reduction potential of the optimal working conditions in each direction for a typical office in Guangzhou.Sensitivity analysis is applied to identify the key parameters affecting the vertical PV louvre shading device.The optimal working conditions for energy performance in each direction are obtained through global optimisation.The results indicate that the louvre rotation angle Ap and louvre pitch Dp are the key parameters that affect the energy performance of the vertical PV louvre device.The device is capable of significantly reducing the energy consumption of the room in all orientations,improving the indoor light environment,and showing a high potential for carbon reduction.
