Modifying Courtyard Wall Geometries to Optimize the Daylight Performance of the Courtyard
A Courtyard in a building regulates its daylight, air movement and thermal interaction with the outdoor environment. The daylight performance of a courtyard depends principally on how the daylight received and delivered into interior spaces. The current research investigates how courtyards vertical surface geometries could improve the daylight in adjacent spaces of the courtyard. The research used Radiance to investigate the impact that vertical walls, inward sloped walls, outward sloped, staggered walls and double layer walls could have on both daylight quantity and quality. Courtyards with inward sloped, inward staggered and double layer walls were found to improve the daylight quality and control the excessive light level, while outward sloped and outward staggered walls increase daylight level.
