Architects love to design with glass, and good daylighting design requires higher window to wall ratios. However, windows are often seen as the weak link in a building because of the solar gain increased window ratios bring. In fact there is a significant downward pressure on window areas in recent building code revisions because of the need to reach increasing levels of energy performance. However, the building energy equation is not just about thermal performance: Windows can be turned into an energy positive if used appropriately as part of an integrated façade. Electrical lighting energy accounts for approximately 20 percent of energy consumption in buildings, approximately 38 percent of total building electricity use and 22 percent of the total electricity generated in the United States. Up to 80 percent of this electrical energy ends up as heat generated by lights which then has to be removed by the air conditioning system. Therefore, optimizing the use of natural daylight to offset the use of electric lighting energy has the potential for significant energy savings at both the building and national level as well as for improving the quality of the built environment. This course will discuss the energy benefits of daylighting with electrochromics, how these systems are controlled, and design considerations such as quality of light and zoning. Example case studies will also be reviewed.
