Efficient mechanical systems include Variable Air Volume (VAV) heating, cooling and air conditioning (HVAC) systems, which are serviced by a water-cooled air-handling unit on each floor with variable frequency drives for VAV control. The building is also equipped with a waterside economizer, which allows the use of “free cooling” from outdoor air when possible to provide cooling and avoid the use of mechanical chillers. The tower portion of the building (floors 5 to 10) is equipped with low-E insulating glass, which has a winter U-value of 0.3, a summer U-value of 0.26 and a Shading Coefficient of 0.27. Glazing on floors 1 to 4 has a shading coefficient of 0.44, as the levels are partially covered by the tower and did not require the same thermal performance as the tower glazing.
