Predicting glare from daylight through microstructures solar control systems using matrix-based simulation methods in Radiance

In this study the five-phase method and a parallelized invocation of evalglare has been used, to evaluate performance microstructure Low-E window w/wo external blind, in terms glare. The first part results investigates how Bidirectional-Scattering-Distribution-Functions, BSDF, aBSDF (Aperture BSDF) properties bias predicted glare through microstructure, linking BSDF rank saturation resolution contrast investigation found combination correct rank, low peak extraction (aBSDF) be best trade-off between speed accuracy. later comparison none investigated systems sufficient protection. was outperform blinds, using current shading schedule (9% difference occupied hours exceeding DGP 0.45).
