Thermal zone's annual heating and cooling load

edit

Thank you very much. I have tried the suggested method, but it did not give me the required values. For example, when I added up the heating load of all the thermal zones when each one was conditioned individually, it did not match the total heating load of the entire building when all the thermal zones were conditioned together. Additionally, I noticed that when only one thermal zone (thermal zone 1) was conditioned while the others were not, the air temperature of an unconditioned thermal zone (thermal zone 2) was not the same as when the entire building was unconditioned.
