There is a problem with the simulation value of heating and cooling energy of archsim.

hi all

I am studying archsim.

I see the tutorial video and apply it to my project. We did an energy usage analysis per hour. However, some values were derived as "0". I set the schedule to "occoffice". Therefore, I think that data between 8 and 19 can not be "0". Of course, the sum of heating and cooling. What's wrong with me?
