Lighting control systems were once comprised of relay panels with low voltage switches, connected to some form of scheduling or time clock. Today, lighting control systems can be network-based solutions that are intelligent, addressable, centralized, and feature two-way communication, according to an article on the Facility Executive website.
These functions allow facility managers to customize lighting operations based on the makeup and architecture of a building.
For instance, Toronto General Hospital in Ontario, Canada, identified an opportunity for significant savings in lighting energy.
After a new energy management system was installed, the hospital reduced its lighting energy consumption by approximately 74 percent.
