Abstract

Abstract: This paper analyzed the accuracy of simplified glare analysis methods compared to the Daylight Glare Probability (DGP) through a parametric study. It consisted of glare calculations in a sample office room, with varying façade layout and orientation. Calculations were performed with Radiance, obtaining the simplified and full glare indices for each case. The different options were compared for discrete daylight conditions as well as for complete annual simulations. As a final output of the research, a new metric is proposed based on the cylindrical illuminance. This has the advantage of retaining the vertical component of illuminance, while being view independent.
