• Use dimming controls. To enhance the economic beneﬁts and provide for a smoother transition between light conditions, use dimmable or multistepped lighting controlled by photosensors. There should be com- patibility between ballast, lamps and controls. Mount the photosensors in a location that closely simulates the light level (or can be set by being proportional to the light level) at the work plane. • Select compatible electric light ﬁxtures. Use indirect lighting ﬁxtures that more closely represent daylight. Consider the furniture and space layout. Notice the light direction and the potential for glare. This is particularly important when deciding the location of computers. • Subsequent articles by the author, discussing water and integrated design, will be published in future issues. • ABOUT THE AUTHOR Michael Nicklas, FAIA, is president, cofounder and design principal at Innovative Design, Inc., in Raleigh, N.C. He is past president of the International Solar Energy Society. Recently, he served on the project committee of ASHRAE’s publication, Advanced Energy Design Guide for K–12 School Buildings: Achieving 30% Energy Savings Toward a Net Zero Energy Building. Durant Road Middle School was constructed under budget. The first year savings attributed to the daylighting and roof assembly were over $0.50/ft2. The additional cost for the 150,000 ft2 facility was $115,000, and the simple payback was less than two years.
