Hello everyone! I wonder if there is any way to add simple equations and input to energy plus. The main reason that I want to do this is because I want to utilize an adaptive method (that is not ASHRAE55 and EN15251) as an input to my 'AirflowNetwork: Multizone:Zone' in the field 'Ventilation Control'. The easiest solution that I see is creating a schedule with varying setpoint temperatures according to outside temperature but for that I would've to input equations.

Is that possible?

Thank you

If your setpoint temperatures are only dependent on outside temperature, then you can pre-process the weather file and create a static schedule for EnergyPlus.

But if your setpoint temperatures need to vary based on other conditions such that they need to be calculated dynamically for each time step, then you can use EnergyPlus's Energy Management System (EMS) to implement custom equations/logic. For example, you can create an EMS program where you actuate (override) a Schedule Value. The EnergyPlus documentation has an example of doing just this.
