Offices are laid out from the furniture plan: power and task light go where people sit, sensors and schedules run the general lighting, and energy codes require part of the receptacles to switch off automatically.
Space | Power | Switching | Lighting |
Open office | Furniture feeds, power poles or floor boxes; one or two circuits per 4–6 workstations | Zone keypads at entries; ceiling occupancy and daylight sensors | Troffers on an 8–10 ft grid or pendants at least 8 ft above the floor; 30–50 fc on desks |
