Abstract:
This 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).
