Type

Type: integer
Minimum: 1
Maximum: 1
Default: 1

Multiplier

Type: integer
Minimum: 1
Default: 1

Ceiling Height

Type: real number
If this field is 0.0, negative or autocalculate, then the average height of the zone is automatically calculated and used in subsequent calculations. If this field is positive, then the number entered here will be used. Note that the Zone Ceiling Height is the distance from the Floor to the Ceiling in the Zone, not an absolute height from the ground.
Unit: m
Default: autocalculate
Values in example files: from -9999.0 m to 5.0088 m

Volume

Type: real number
If this field is 0.0, negative or autocalculate, then the volume of the zone is automatically calculated and used in subsequent calculations. If this field is positive, then the number entered here will be used.
Unit: m3
Default: autocalculate
Values in example files: from 0.0 m3 to 5605.3198 m3

Floor Area

Type: real number
If this field is 0.0, negative or autocalculate, then the floor area of the zone is automatically calculated and used in subsequent calculations. If this field is positive, then the number entered here will be used.
Unit: m2
Default: autocalculate
Values in example files: empty in 169 files, autocalculate m2 in 608 files

Zone Inside Convection Algorithm

Type: choice (Simple, TARP, CeilingDiffuser, AdaptiveConvectionAlgorithm or TrombeWall)
Will default to same value as SurfaceConvectionAlgorithm:Inside object setting this field overrides the default SurfaceConvectionAlgorithm:Inside for this zone Simple = constant natural convection (ASHRAE) TARP = variable natural convection based on temperature difference (ASHRAE) CeilingDiffuser = ACH based forced and mixed convection correlations for ceiling diffuser configuration with simple natural convection limit AdaptiveConvectionAlgorithm = dynamic selection of convection models based on conditions TrombeWall = variable natural convection in an enclosed rectangular cavity

Zone Outside Convection Algorithm

Type: choice (SimpleCombined, TARP, DOE-2, MoWiTT or AdaptiveConvectionAlgorithm)
Will default to same value as SurfaceConvectionAlgorithm:Outside object setting this field overrides the default SurfaceConvectionAlgorithm:Outside for this zone SimpleCombined = Combined radiation and convection coefficient using simple ASHRAE model TARP = correlation from models developed by ASHRAE, Walton, and Sparrow et. al. MoWiTT = correlation from measurements by Klems and Yazdanian for smooth surfaces DOE-2 = correlation from measurements by Klems and Yazdanian for rough surfaces AdaptiveConvectionAlgorithm = dynamic selection of correlations based on conditions

Part of Total Floor Area

Type: choice (Yes or No)
Default: Yes
