The Illini Union has demolished its old cooling towers for HVAC in the past 15 years, and recently demolished the old evaporator cooling system for the refrigeration chilling water in 2017. Almost all of our HVAC is now on DDC, with the exception of AHU’s 1, 2, & 3 in the South Building attic, and AHU-21 in the North Building NW subbasement.
Water Station Foreman, Shawn Young, indicated today that there are two remaining stand-alone cooling towers on campus buildings maintained by F&S: Temple Buell Hall and the Personnel Services Building. One of these (Personnel) is scheduled to be added to the central chilled water loop in 2020, according to the Utilities Energy Production and Distribution Master Plan. Base on that discussion, Morgan Johnston will be following up with the Water SWATeam to let them know that because there are so few remaining stand-alone cooling towers, this is not a high-priority item to pursue.
Morgan Johnston and Chenxi Jiang have requested a meeting with Dave Boehm and other Building Maintenance representatives to discuss the options for implementing a new water conservation strategy for stand-alone building rooftop cooling towers.
