Step 2: A Smarter Building, A More Efficient Building

Air Handling Units on every floor cycle fresh air in and out, cooling and ventilating the building. Different parts of the building have different heating and cooling needs: some sides get more sun than others, and higher floors are exposed to colder air and higher wind. The old units, like the chillers, were either on or off, resulting in wasted energy. The new units use Variable Air Volume (VAV) technology to constantly fine tune their output to match the cooling and ventilation demands of different building spaces, as sensed by the building's central control network. VAV technology is another "gas pedal," allowing units to run only when needed.
