Building managers, contractors and designers are looking for new ways to leverage the data from various building systems, sensors, and network-connected devices to improve the design, construction, and maintenance of buildings. The role and value of lighting control system (LCS) data in this future remains a looming question. This presentation will delve into actual LCS data collected from educational and healthcare facilities to explore how this feedback can be used to optimize spaces for occupant benefit, energy and operational efficiency, and inform design and best practice.
