I want to measure the difference rate of Electricity facility ,heating energy transfer and cooling energy transfer according to the building solar orientation .I changed the north axis frequently and set the other fields in Global Geometry rules on relative option but there are no differences in output fields in spread sheets. How can I solve this problem?

Thank you

please specify what simulation engine you are using, but regardless of tool being used, have you confirmed that thermostats and that HVAC equipment are associated with the thermal zones? Also is your building symmetrical and are you only rotating in 90degree increments?

I simulated in the open studio and confirmed thermostats to the zones and HVAC template zone ideal load air system.My building is symmetrical and i want rotate it in -30 and 30 degree.

With ideal loads, you won't see any change in electricity, but you should see changes in District Cooling and District Heating.
