I would note that the room level controls at the National Soybean Research Center have been upgraded to DDC in the past year.  We plan to do this in the ACES Library in 2021.  We have invested in Turner Hall w/ control upgrades and RCx work. The Ag Engineering building saw a recent project last year to upgrade to DDC controls and replace VAV boxes.  ~Karl Helmink, F&S RCx, january 2021
