For large internal-load-dominated ILD buildings, artificial lighting without daylighting is usually more than half of total electric load and as much as 80 percent of the total thermal load. Recent analyses of large building such as libraries and offices indicate that at least 20 percent of the electric lighting (and its associated heat production) can be readily displaced with appropriately designed daylighting that avoids glare and solar heat gain. A total of 36 atrium canopy configurations were parametrically evaluated with physical scale models under different sky and sunlight conditions. Effective transmittances for different well configurations were determined as the ratio of canopy-covered daylight factor DF to base case daylight factor BCDF. Data analysis for sunlit atria was performed with sunlight illuminance ratios SIR obtained with and without canopies. Luminance ratios, sunpatches, and glare potential were also evaluated with the instrumentation system developed in this work.
