Description

Illumination and solar radiation measurements have been made on a scale-model building containing sloped, south-facing, double-pane roof glazing (Figure 4). To control glare and properly disperse the beam sunlight over the work plane, a good diffusing glazing is used for the inside pane of the roof aperture. Measurements have been made in order to investigate the performance of this day lighting system under clear sky conditions in response to changes in a variety of interior design options. The results indicate that with modest glazing areas the roof aperture system provides a work-plane illuminance that is more than adequate in quantity and uniformity. Among the interior design options that are shown to have significant effects on the day lighting system performance are interior surface reflectances, overhead obstructions, and interior partitions. In this paper the outdoor experimental facility and scale-model building are described. The results of the scale model experiments are presented and discussed.
