In 2013, the SPEED team collaborated with UC San Francisco to demonstrate three lighting retrofits of fluorescent fixtures. Three control systems, each with different system architectures, were installed in three different UCSF corridors. All three systems utilize occupancy controls, but each one provides a different level of control, different programming capabilities, and energy and maintenance monitoring features. The demonstrations produced energy savings of 53–68%, based on occupancy rates of 12–16%.
