Exchange old exit signs for ENERGY STAR® qualified signs. They last longer, reduce maintenance, and can save up to $10 per sign, the energy equivalent of 500 pounds of greenhouse gas emissions, each year. That’s like each sign you replace saving you two tanks of gas per year.
Swap the bulbs in overhead and task lights for LED bulbs, which enhance the work environment, use 80 percent less energy than incandescent bulbs, and use 50 percent less energy than fluorescent lighting.
Upgrade to more efficient alternatives for parking lot and outdoor signage lighting, such as metal halide lamps in lots and LEDs for signs.
Install occupancy sensors, which automatically shut off lights when rooms aren’t in use.
