Meriter Hospital, Madison, WI – Chilled Water Distribution System

Retro-commissioned the primary/ secondary chilled water distribution system for the 800,000 sq. ft. campus. Work included a detailed analysis of the cooling coil performance of 71 air handling units. Coil performance was re-modeled for 40 deg.F entering chilled water and 5 deg. F leaving air temperature with water-side delta Tee's ranging from 7 deg. F to 20 deg. FF with an average of 12.4deg F back at the chiller plant. The campus was re-balanced to the new design flows of 6,000 US GPM and environmental comfort for the entire facility improved dramatically (1997).
