Dear Dr.Li ,
Thank you from your kindness and replying to my questions
I Changebuilding ground temperature to 18°C for Tehran , and the warning eror ".Site:GroundTemperature:BuildingSurface: Some values fall outside the range of 15-25C " disappear .
You say, i can add ventilation in Summer without adding air-conditioners. Ventilation would remove moisture as well.
yes you r right but i just want to simulate it during winter , and aslo in idf file i put :zoneventilation:Designflowrate .
You say ,i have 130 FTFFF warnings. 6 x 24 = 144 timesteps for one day. I did not check whether you have by-pass branches installed in the plant loop or not. Without the by-pass branch the flow quantity can goes to zero. Since you only have zone equipment, it is passed. The plant should pass as well, if the flow is not zero.
yes you r right i didnt have bypass branches intalled in the plant loop , now i put branch by-pass in my idef , but still there is FTFFF warnings.
You do not have any cooling equipment, the the cooling load for all the zones is zero. The cool setpoint for the zone thermostat may have caused this warning
yes i dont have any cooling equipment , but i dont use cooling setpoint i use heating setpoint ( in zonecontrol:thermostat and control type is 1-thermostatsetpoint:singleheating.)
The heating setpoint is the zone thermostat value. The baseboard heater should be linked to the zone thermostat. You can provide different setpoint schedule for each zone to verify that they are controlling the baseboard heater.
how i could verify they are controlling the baseboard heater ?
as you say:.
In a real system, the radiator temperature are all different, and the boiler temperature is also not constant. You may leave the radiator valve rully open and adjust the boiler temperature, so that the occupants have no control of the system temperature. This is the most practical way.
,i leave the radiator valve rully open and adjust the boiler temperature, so that the occupants have no control of the system temperature.
so i set the avarage of data zone temperature that i measured for whole two month of january and febuary, as heating setpoint . baseboard dont controll by this temperature , , i mean the heat of baseboard cause this temperature .
so why you say " The baseboard heater should be linked to the zone thermostat" and " verify that they are controlling the baseboard heater " ?
i attached the picture of this building
thankyou very much

You have a large building to model. On the whole the warning on non-convex surfaces may be ignored.
The error file and the edited IDF file is attached. I removed about 300 of your meter variables.
