Re: [EnergyPlus_Support] Assigning a temperature to an inside surface

[Simge Andolsun <simgeandolsun@xxxxxxxxx>]

Dear Jason,

Thanks for your reply. What do you mean by "iteratively adjusting your otherside cofficients definition"? Could you please explain it? 

I thought of modeling the construction as a massless, very low resistance surface (0.001 m2K/W= Minimum allowable material resistance in EnergyPlus) and assigning the interior temperatures I have as the outside temperatures of this massless, very low resistance construction. Do you think it makes sense? Please let me know.

Thanks in advance for your help,

Best Regards,

Simge,

You could use SurfaceProperty:OthersideCoefficients to schedule a constant or time varying temperature on the exterior of a surface.
You could then  report the below variables and iteratively adjust your otherside coefficients definition until you get the desired temperature / profile
To do this, in the desired BuildingSurface:Detailed, change the outside boundary condition to OtherSideCoefficients and then reference that objects name in the 'Outside Boundary condition object' field. Be sure to read about the otherside coefficients object in the I/O reference as using this will cause the simulation to ignore the external
environment for that surface.

Output:Variable,*,Surface Inside Temperature,hourly; !- Zone Average [C]
Output:Variable,*,Surface Int Adjacent Air Temperature,hourly; !- Zone Average [C]

Hope this helps.

Dear EnergyPlus users,

Is it possible to assign a temperature (or a set of varying temperatures) to the inside surface of a construction in EnergyPlus? If there is, could you please describe how it is used?

Thanks in advance,
