Step 2: A Smarter Building, A More Efficient Building


Improving the efficiency of the building's exterior (Step 1) reduced our demand for heating, ventilation and air conditioning systems. Next, we looked inside the building for opportunities to become more efficient. A massive circulatory system of pipes, valves, ducts and wires works behind the scenes to supply heat, light, air and air conditioning to tenants and visitors. These systems in many buildings share a common flaw: they are on or off with no way to adjust output, which wastes energy and creates hot and cold spots.

You wouldn't drive a car that only went full speed or not at all. You need a gas pedal and a speedometer – a way to adjust the car's velocity and monitor its speed. Step 1 is upgrading to equipment that can run at variable speeds, and Step 2 is providing a mechanism to monitor and control it.
