Recent studies of electrochromic glazing systems have primarily focused on studying the energy use characteristics of conventionally sized systems in mild climates, using either a fully automated control scheme or a combination of automated controls and various methods of occupant feedback, and have identified the potential for such systems to reduce annual energy use. This study will investigate the potential for a commercially available electrochromic glazing system to reduce building energy use and respond to dynamic occupant requirements when coupled with a real-time human gestural control system. Using the recently constructed, outdoor Thermal Lab facilities at the University of Texas at Austin, we will perform the first test of an electrochromic system’s ability to meet these demands. The use of small-scale, individually switchable electrochromic glass panels will demonstrate the capabilities of the system to manage glare, allow transmission of sufficient light, and preserve views for a human occupant. By offering users a simple, intuitive language of gestures with which they can seamlessly interact with the electrochromic control system, we will explore the potential for the building envelopes of the future to create truly personal interior environments that are directly responsive to the demands of their occupants.
