Is there any way to manually edit the Zone Air Temperature?
Right now I am using Energy Plus. I am just conducting a simple experience of 'Steady State' where I use 'No Weather File' and simulate the program with the 'SizingPeriod:DesignDay". Right now, I am only considering the 'Winter' for the steady-state condition. While I found ways to control the outside temperature, the spreadsheet is fixed at 20 Celsius for 'Zone Air Temperature'. Is there any way to change that '20 Celsius Zone Air Temperature'?
The zone air temperature is typically an output of EnergyPlus rather than an input. If the spreadsheet output is 20 deg C for ZAT at all timesteps, I would think you have a mechanical HVAC system maintaining a 20 deg C heating and cooling setpoint(s). Is that the case for your model?
