Is it possible to feed surface temperatures to EnergyPlus?

retag add tags

Hey guys,

I am curious, because I have a wall I'm trying to simulate in Delphin and I need the room temperature as an input to calculate the surface temperature, and my surface temperature are influencing the room temperature. Is it possible to make such a link? So I what to calculate the surface temperature in Delphin, give it to EP, calculate the room temperature and then give that to Delphin and so on.

I hope you get what I'm trying to do, or otherwise feel free to ask.

Thanks in advance

Yes, it is possible. You can do this selecting OtherSideCoefficients in the Outside Boundary Condition field of the BuildingSurface:Detailed object (i.e. the wall or surface) and referencing a SurfaceProperty:OtherSideCoefficients object. That SurfaceProperty:OtherSideCoefficients object can have whatever temperature you like - a constant, or scheduled value. There is more detail in the InputOutput reference guide that comes with the EnergyPlus installation.

Hope this helps.

Thanks for the help. I have some follow up questions though. How do I create this OtherSideCoefficients Object? At the moment I can only create another surface and reference it, but I don't know how to create the temperatures for it?

Let's say I make the temperature a schedule. Can I edit the scheduled value for the next time step of the simulation, while it is running?
