Designing a dynamic fenestration to improve visual performance in educational spaces using daylight

Abstract

This research studies the daylighting performance of diverse design prototypes of a classroom unit. The prototypes are suggested for high-performance approach that reflects a dynamic design, through the incorporation of daylight that will boost up the learning experience. Simulation is carried out using Radiance and Daysim for daylighting measurements and Evalglare for glare analysis. Window to Wall Ratio (WWR) and window-sill height are designed to provide the optimum daylight levels for students performing different educational tasks. These two variables are evaluated according to certain goals and within certain constraints to refine the optimum solution. The result of this research is a design of dynamic façade that opens and shuts in response to the illumination levels required by the task performed; such as traditional learning, discussion or computer activities. The function of the dynamic façade is to achieve uniform and sufficient daylight in the classroom to perform visual tasks with minimal discomfort caused by the glare.
