Designing a Kinetic Façade to Control Glare: Inspiration of Long-Day Plants Pattern

Abstract

In this study, to control glare in buildings with glass facades, a kinetic facade was designed using a pattern inspired by nature. Accordingly, in this study, due to the essential similarity of buildings with plants regarding the inability to move and location, in the first step, plants and their morphology were examined. Among them, long-day plants, which offer greater shading capacity than other plants, were selected as the basis for modeling. In the next stage, computational simulations were conducted using Rhino and Grasshopper software along with Ladybug and Honeybee plugins to analyze sunlight and daylight performance. The simulation results of annual climate-based daylight metrics and luminance-based metrics demonstrated that the kinetic facade inspired by long-day plants outperformed the Reinhart reference office room with horizontal shading in terms of glare control and useful daylight. In other words, the kinetic facade designed in this study effectively provides sufficient daylight and prevents glare as well.
