Instant Light Dimming

Energy savings: 50% to 75%
Payback time: 18 to 24 months

Lighting accounts for up to 35% of a commercial building's energy costs, but much of it is lighting empty rooms. Enlighted Inc. installs a device in light fixtures that brighten and dim automatically, reacting to body movement and other sources of light everywhere in an office.

Energy savings: 15% to 20%
Payback time: 18 to 24 months

Devices by Incenergy are connected to rooftop heating and cooling units. They communicate directly with a smartphone app, which managers can use to adjust temperatures from anywhere.

Energy From Wasted Heat

Energy savings: 20%
Payback time: 3 to 4 years
