SURFACEPROPERTY:OTHERSIDECOEFFICIENTS

This object sets the other side conditions for a surface in a variety of ways.

Name

Combined Convective/Radiative Film Coefficient

Type: real number
If>0, this field becomes the exterior convective/radiative film coefficient and the other fields are used to calculate the outdoor air temperature then exterior surface temperature based on outdoor air and specified coefficient if<=0, then remaining fields calculate the outside surface temperature The following fields are used in the equation: OtherSideTemp=N2*N3 + N4*OutdoorDry-bulb + N5*GroundTemp + N6*WindSpeed*OutdoorDry-bulb + N7*TempZone + N9*TempPrev
Unit: W/m2-K

Constant Temperature

Type: real number
This parameter will be overwritten by the values from the Constant Temperature Schedule Name (below) if one is present
Unit: C
Default: 0

Constant Temperature Coefficient

This coefficient is used even with a Schedule. It should normally be 1.0 in that case. This field is ignored if Sinusoidal Variation of Constant Temperature Coefficient = Yes.
Default: 1

External Dry-Bulb Temperature Coefficient

Type: real number
Default: 0

Ground Temperature Coefficient

Type: real number
Default: 0

Wind Speed Coefficient

Type: real number
Default: 0

Zone Air Temperature Coefficient

Type: real number
Default: 0

Constant Temperature Schedule Name

Type: list of objects (SCHEDULE:COMPACT, SCHEDULE:FILE, SCHEDULE:CONSTANT, EXTERNALINTERFACE:SCHEDULE, EXTERNALINTERFACE:FUNCTIONALMOCKUPUNITIMPORT:TO:SCHEDULE or SCHEDULE:YEAR)
Name of schedule for values of constant temperature. Schedule values replace any value specified in the field Constant Temperature.

Sinusoidal Variation of Constant Temperature Coefficient

Type: choice (Yes or No)
Optionally used to vary Constant Temperature Coefficient with unitary sine wave
Default: No

Period of Sinusoidal Variation

Type: real number
Use with sinusoidal variation to define the time period
Unit: hr
Default: 24

Previous Other Side Temperature Coefficient

Type: real number
This coefficient multiplies the other side temperature result from the previous zone timestep
Default: 0

Minimum Other Side Temperature Limit

Type: real number
This field specifies a lower limit for the other side temperature result. Blank indicates no limit
Unit: C

Maximum Other Side Temperature Limit

Type: real number
This field specifies an upper limit for the other side temperature result. Blank indicates no limit
Unit: C
