Optimizing Daylighting in Building Design: A Comparative Study of Metrics and Shading Strategies Toward Daylight Optimization

Daylighting, a vital component of sustainable building design, is the focus of this engaging and collaborative study. In this study, we have utilized parametric modeling and optimization techniques to explore key daylighting metrics. The research presents a case study of the Monterey Building in San Antonio, Texas, using Grasshopper and Galapagos to identify window-to-wall ratio design dimensions for the south façade and shading depth. It also includes simulations using Rhino and Climate Studio to calculate the parameters of various daylighting strategies such as Spatial Daylight Autonomy (sDA), Annual Sunlight Exposure (ASE), Daylight Glare Probability (DGP), and quality view. After a thorough analysis, we have concluded that the most effective shading type for the south façade with a WWR of 50% for the Monterey Building in San Antonio, Texas, is overhangs with vertical louvers that have a depth of 4m. This procedure achieves the best spatial daylight autonomy (sDA) and good-quality view while minimizing glare. The results of this collaborative research offer valuable insights for optimizing daylighting performance through parametric approaches, contributing to more sustainable and adaptable building designs.
