Re: [EnergyPlus_Support] temperature curve

["Michael J. Witte" <mjwitte@xxxxxxxx>]

OtherSideCoefficients allows you to assign a schedule as the outside surface 
temperature for any surface.  

1.  In Surface:HeatTransfer, OutsideFaceEnvironment=OtherSideCoeff and 
OutsideFaceEnvironment Object="Scheduled Ground Temp" (or whatever name you 
choose).  

2.  Then add this object:

OtherSideCoefficients,
    Scheduled Ground Temp,   !- OtherSideCoeff Name
    -1, !- Combined convective/radiative film coefficient
     0, !- User selected Constant Temperature {C}
     1, !- Coefficient modifying the user selected constant temperature
     0, !- Coefficient modifying the external dry bulb temperature
     0, !- Coefficient modifying the ground temperature
     0, !- Coefficient modifying the wind speed term (s/m)
     0, !- Coefficient modifying the zone air temperature part of the equation
    Ground Temp Schedule;    !- ScheduleName for constant temperature

3.  Create the appropriate "Ground Temp Schedule" objects.

4.  Be sure to report the outside surface temperature to confirm the values are 
what you expect.
