NATIONWIDE CHILDREN’S – WEST CENTRAL ENERGY PLANT

Design of a West Campus Central Energy Plant and utility distribution. The central plant includes electrical distribution switchgear, standby generators and the associated distribution switchgear, high-pressure steam boilers, and electric chillers and the associated cooling towers. New underground tunnels and separate electrical duct banks facilitated the utility distribution. The chiller plant is in a prominent location on the hospital’s West Campus, which is currently in development. In addition to the building adapting to a “wedge” site, the building was designed to have architectural features that will coordinate with existing and future buildings on the West campus.
