by Rebecca Walker — May 16,2011—Ball State University in Muncie, Ind., is using new dynamic window technology from SAGE Electrochromics to optimize daylight while preserving energy and beautiful views in a student building.
Ball State installed SAGE’s SageGlass electrochromic glass in a multipurpose residence hall space to create a glass ridge roof that bathes the interior in abundant natural light while controlling solar glare, fading and heat gain. SageGlass is an electronically controlled glazing that changes tint with the flick of switch, or uses sensors in response to changing daylight conditions, so that the glass automatically darkens or clears as needed.
According to architect Ryan Benson of Schmidt Associates, Inc., who designed the project, SageGlass was a more eco-friendly and aesthetically pleasing alternative to using conventional skylights and architectural controls such as shades, exterior fins or louvers. It enabled him to incorporate more glass into the project without compromising on energy efficiency and a view to the outdoors.
Historically, non-variable windows have accounted for about 30 percent of a building’s heating and cooling energy usage. SageGlass has been shown in government studies to reduce energy loads for buildings by up to 20 percent and lighting costs by 60 percent, while providing building occupants with optimal, unencumbered daylight and greater comfort.
SAGE Electrochromics is a leading developer of dynamic window glass that changes tint to optimize daylight and improve the human experience within buildings. For more information, see the Web site.
