In which location are motion sensors recommended by BPI?

• A. Elevator lobbies
• B. Compactor rooms
• C. Laundry rooms
• D. Mechanical rooms

Answer: (B)

Motion sensors are used to automatically control lighting in spaces that aren’t occupied constantly, turning lights on when someone enters and off after they leave. This pattern fits a compactor room well: these rooms are small, used intermittently for trash handling or maintenance, and often left dark when not in use. Without sensors, lights can stay on for long periods, wasting energy and increasing operating costs. A motion sensor ensures lighting is available as soon as someone steps in for a task, improving visibility and safety, while preventing lights from running unnecessarily when the room is empty. In contrast, elevator lobbies usually need more consistent lighting for security and accessibility, laundry rooms are frequently used at varied times, and mechanical rooms are often kept lit for maintenance safety, so they don’t offer the same energy-saving advantages from occupancy-based controls.
