OpenStudio Cooling Load is Zero on the Results tab

edit

Hello everyone. I am working on a Hotel project and I ran into a problem at the results tab. Even though I have specified that the Hotel has a cooling tower for Cooling, when i run up the simulation, the Energy used for cooling is 0. I 've created a Hot Water Loop which contains a Natural Gas Burner and a Cooling Water Loop which contains a Cooling tower and a cooling coil. I use an Air Loop with a combination of Heating/Cooling coils so the thermal zone temperature is mixed and adjusted likewise. Heating Works fine, but It seems like the cooling sector isn't taken on account at all.

Feel free to browse on my project files below.
