NoMultizoneOrDistribution: Only perform Simple calculations (objects ZoneInfiltration:*, ZoneVentilation:*, ZoneMixing, ZoneCrossMixing, ZoneRefrigerationDoorMixing, ZoneAirBalance:OutdoorAir, ZoneEarthtube, ZoneThermalChimney, and ZoneCoolTower:Shower); MultizoneWithoutDistribution: Use AirflowNetwork objects to simulate multizone Airflows driven by wind during simulation time, and objects of ZoneInfiltration:*, ZoneVentilation:*, ZoneMixing, ZoneCrossMixing ZoneRefrigerationDoorMixing, ZoneAirBalance:OutdoorAir, ZoneEarthtube, ZoneThermalChimney, and ZoneCoolTower:Shower are ignored; MultizoneWithDistributionOnlyDuringFanOperation: Perform distribution system calculations during system fan on time and Simple calculations during system Fan off time; MultizoneWithDistribution: Perform distribution system calculations during system fan on time and multizone Airflow driven by wind during system fan off time.

Default: NoMultizoneOrDistribution

Input: User must enter AirflowNetwork:MultiZone:WindPressureCoefficientArray, AirflowNetwork:MultiZone:ExternalNode, and AirflowNetwork:MultiZone:WindPressureCoefficientValues objects. SurfaceAverageCalculation: used only for rectangular buildings. If SurfaceAverageCalculation is selected, AirflowNetwork:MultiZone:WindPressureCoefficientArray, AirflowNetwork:MultiZone:ExternalNode, and AirflowNetwork:MultiZone:WindPressureCoefficientValues objects are not used.

Default: SurfaceAverageCalculation

If ExternalNode is selected, the height given in the AirflowNetwork:MultiZone:ExternalNode object will be used. If OpeningHeight is selected, the surface opening height (centroid) will be used to calculate local wind pressure This field is ignored when the choice of the Wind Pressure Coefficient Type field is SurfaceAverageCalculation.

Default: OpeningHeight

Used only if Wind Pressure Coefficient Type = SurfaceAverageCalculation, otherwise this field may be left blank.

Default: LowRise

Determines the maximum number of iterations used to converge on a solution. If this limit is exceeded, the program terminates.

Unit: dimensionless

Maximum: 30000

Default: 500

Default: ZeroNodePressures

This tolerance is defined as the absolute value of the sum of the mass Flow Rates divided by the sum of the absolute value of the mass Flow Rates. The mass Flow Rates described here refer to the mass Flow Rates at all Nodes in the AirflowNetwork model. The solution converges when both this tolerance and the tolerance in the next field (Absolute Airflow Convergence Tolerance) are satisfied.

Unit: dimensionless

Default: 1.E-4

This tolerance is defined as the absolute value of the sum of the mass flow rates. The mass flow rates described here refer to the mass flow rates at all nodes in the AirflowNetwork model. The solution converges when both this tolerance and the tolerance in the previous field (Relative Airflow Convergence Tolerance) are satisfied.

Unit: kg/s

Default: 1.E-6

Used only for AirflowNetwork:SimulationControl

Unit: dimensionless

Minimum: -1

Maximum: 1

Default: -0.5

Degrees clockwise from true North. Used only if Wind Pressure Coefficient Type = SurfaceAverageCalculation.

Unit: deg

Minimum: 0.0

Maximum: 180.0

Default: 0.0

Used only if Wind Pressure Coefficient Type = SurfaceAverageCalculation.

Maximum: 1.0

Default: 1.0

If Yes, external node temperature is height dependent. If No, external node temperature is based on zero height.

Default: No
