Do people in the building often come in early or leave late? Are they comfortable entering a dark space or leaving via a dark parking lot? In an emergency, will everyone be able to see well enough to get to safety? If security is your priority, you can make sure nobody is in the dark and save energy, too.

Light controls help ensure employee safety and security. A time clock or central computer program can turn lights on and off, set lighting levels for different times of day, and change the lighting profile for an after-hours mode. Motion sensors can dim the lights (rather than turn them off) when space is unused, to reduce employee concerns while saving energy. Integrate emergency lighting into the overall system to provide the right light and simplify the lighting plan.
