ABSTRACT
Daylight design using toplighting strategies provides an opportunity to introduce illumination in a potent and uniform manner throughout the year and minimizes the concerns related to blind type and patterns of blind use. When designing toplighting for classrooms, and most space types, it is important to consider the size and placement of the apertures, their proximity to adjacent reflective surfaces, line of sight to the apertures to avoid glare, and ceiling height. A sloping t-bar tray and an opaque reflector were hung below the skylight to decrease the illumination directly below the skylight, redirect the brightness onto the ceiling and walls, and minimize the line of sight to the aperture. The as built condition utilizes a large skylight representing 14" skylighting-to-floor area ratio (SFAR), with sloped ceilings and an angled and staggered aluminum reflector. The reflector decreases illumination directly below the skylight, redirects brightness onto the ceiling and walls, and minimizes the line of sight to the skylight.
