I took a look at you screenshots and there are many things wrong with them. Firstly, you have a plant loop that has in the supply side a boiler before the cooling tower and the demand side has hydronic cooling coils. Since your cooling coils do not have any nodes above and below they can only be connected with zone equipment or nothing but I can't tell from these screenshots. I am not sure what you were trying to model but cooling towers are supposed to cool water for chillers so both the boiler and the connection with the cooling coils are wrong. In case you were trying to model a strainer cycle this is not the correct way to model it. Lastly, to answer your original question, from what I understand the only thing that conditions your thermal zone is your airloop which does not have a cooling coil (DX or water) and this is probably why you do not have any cooling loads.
