Abstract:
This study presents a method for selecting and designing shading strategies that reduce glare and maintain satisfactory daylight levels in buildings. The proposed method employs a multi-objective genetic algorithm to construct Pareto sets, using two indicators: the spatial glare autonomy (sGA), a dynamic glare evaluation indicator, and the spatial daylight vote autonomy (sDVA), based on daylight subjective vote (DSV). DSV is a daylight index developed through a field survey, which builds the relationship between horizontal illuminance levels and subjective satisfaction. The performance of four shading strategies is compared in a university library in Shanghai, namely vertical slats (Vs), perforated aluminum sheet (PAS), serrated windows with southern orientation (Sw_S), and serrated windows with northern orientation (Sw_N). The results reveal that the Sw_N strategy is most effective in reducing glare, while the Vs strategy provides a more satisfactory illuminance level. In the performance of the optimal parameter of the different shading strategies designs, the near-optimal designs for PAS, Vs, Sw_N, and Sw_S greatly reduced the complementary sGA0.35/95%, by 9%, 22%, 8%, and 8%, respectively. The proposed method can facilitate the design of an appropriate daylighting environment. © 2023 IBPSA.All rights reserved.
