The Impact of operated window shading on visual comfort, non-visual health, and energy demand from electric lighting, Building Simulation 2023, Shanghai September 4-6, 2023.https://doi.org/10.26868/25222708.2023.1152https://hdl.handle.net/1794/296528 pagesThis paper introduces a simulation-based workflow to assess annual circadian lighting performance, glare risk and energy demand for an array of seated view positions under operated shading and electric lighting conditions. This workflow uses a combination of 9-band and 81-band simulations to represent daylight and electric lighting respectively. Annual climate-driven calculations rely on python-based code provided by the Lark spectral lighting software, which was used to run 180-degree high dynamic range (HDR) renderings with 9-bands of spectral resolution. The results reveal the impact of shading systems on equivalent melanopic lux (EML) and daylight glare probability (DGP) over time and the energy demand (kWh) from electric lighting systems to supplement eyelevel recommendations from the WELL v2 Building Standard (Feature L03).Articleen-USCreative Commons BY-NC-ND 4.0-USelectric lightingoperated window shadingcircadian lighting performanceglare riskArticle
