Open studio load calculation

Hello I am training with openstudio. My goal is load calculation with openstudio. I don't know what I am doing wrong but I have no load calculation in my reports. My buiding is a single room with 2 windows. No hvac devices is used. Weather file is form montreal , canada.

Thanks a lot for any help.

You need to click the "Enable Ideal Air Loads" checkbox on the Thermal Zones tab for the zones for which you want load to be calculated (and add thermostats schedules for these too)

I did your suggestion. I still don't have a number on HVAC sizing summary in report. How to set indoor Design temperature maybe this is the key.

Indoor design temperatures are controlled by the thermostat schedules that you put for the thermal zones, including their "Design Day" profiles (summer and winter). Also make sure you import design days on the first tab (Load "DDY")
