Spatio-Temporal Visualisation of Refections from Building Integrated Photovoltaics
We present a computational workflow using annual daylight simulation and image-based postprocessing to visualise cumulative annual irradiance and glare duration on the built environment due to reflections from building integrated photovoltaics. The annual daylight simulation considers reflections from measured BSDFs of proposed PV materials. The postprocessing includes a spatio-temporal feature detection to identify sustained glare duration based on recommended thresholds. We demonstrate this workflow with a case-study of a proposed PV roof retrofit for a church in Lucerne, Switzerland.
