This report investigates the operation of circadian lighting systems to gain an understanding of the main design and control characteristics and to promote different objectives for use. Research is guided by asking how color intensity, color temperature and their temporal characteristics are related to the circadian response, and how this knowledge can be utilized when designing and operating lighting systems for indoor environments. This report consists of an extensive literature review and case study application cut short by the impact of the novel coronavirus. The case study takes place in an office space housed on the UNMC campus featuring an installed circadian lighting system capable of changing color temperature and intensity independently. The results of the literature review lead to the understanding of biological impacts of suggested operational patterns for the lighting system. Specifically, the interaction between human physical characteristics as they relate to the current lighting technologies has helped to develop the rational for use of these systems. These biological impacts ultimately aim towards improved occupant attention and well-being in the space. Future investigation and implementation are encouraged to continue advanced analysis of occupant response to varied patterns of operation for this circadian lighting system.
