Lighting in U.S health care facilities accounts for forty-three percent of electricity use, leading many managers to incorporate LED lighting in their energy efficiency programs. However, few are fully leveraging this technology to benefit patients, families, and staff. Features such as directionality, dimming, zoning, and color changing can improve experiences in health care facilities for all occupants. Implementing advanced lighting systems to provide behavioral cues, meet best practices for circadian design, and deliver the quantity of light where it is needed can enhance environments to support healing for patients, while accounting for the wellness of staff. This educational session will explain our current understanding of how light affects not only the ability to perform visual tasks, but also affects circadian functioning and overall mood and well-being. As part of the session, tunable LED lighting will be demonstrated, allowing participants to experience the types of variations in spectrum and intensity these systems can provide.
After explaining the underlying principles and demonstrating the technology, a series of case studies will be presented, illustrating real-world examples of installations of tunable lighting systems. The presenters include an architectural design analyst and U.S. Department of Energy national lab researchers who have collaborated with multiple organizations on these case study projects, including a senior care center in Sacramento, Calif., a behavioral health unit in a hospital in Seattle, Wash. and a behavioral medical unit in a children’s hospital in Philadelphia, Pa. The session will also explain the results of a patient room lighting survey completed by 252 nurses at four hospitals.
