Hello, I have Openstudio version 1.8.0 and I don't understand what I have to do in the “Thermal Zone” section so that I can have the air-conditioning and heating powers to set up after selecting “Run simulation”. 2 years ago, in the “Thermal Zones” section, I know that I had to drag and drop CLG HVAC in the “Cooling Thermostat schedule” section and HTG HVAC in the “Heating Thermostat schedule” section, then run the simulation. I just need to be able to size the heating and cooling capacities I'll need to install in my building. Can anyone help me?
