buildingSMART Data Dictionary

PSD-XML

- Reference
  P_SINGLEVALUE / IfcIdentifier

  | Reference: Reference ID for this specified type in this project (e.g. type 'A-1').
  | 参照記号: このプロジェクトにおける参照記号(例：A-1)。分類コードではなく内部で使用されるプロジェクトタイプとして使用されるもの。

- Status
  P_ENUMERATEDVALUE / IfcLabel / PEnum_Status: NEW, EXISTING, DEMOLISH, TEMPORARY, OTHER, NOTKNOWN, UNSET

  | Status: Status of the element, predominately used in renovation or retrofitting projects. The status can be assigned to as "New" - element designed as new addition, "Existing" - element exists and remains, "Demolish" - element existed but is to be demolished, "Temporary" - element will exists only temporary (like a temporary support structure).
  | 状態: 要素（主にリノベーションまたは改修プロジェクトにおいて）の状態。 状態は、「新規(New)」－新しく追加される要素。「既存」－要素は存在し、かつ残りもの。「破壊」－要素は存在したが、廃棄されるもの。「一時的」－一時的に存在する要素（一時的にサポートしている構造のようなもの）。

- Weight
  P_SINGLEVALUE / IfcMassMeasure

  | Weight: Weight of filter.

- InitialResistance
  P_SINGLEVALUE / IfcPressureMeasure

  | InitialResistance: Initial new filter fluid resistance (i.e., pressure drop at the maximum air flowrate across the filter when the filter is new per ASHRAE Standard 52.1).

- FinalResistance
  P_SINGLEVALUE / IfcPressureMeasure

  | FinalResistance: Filter fluid resistance when replacement is required (i.e., Pressure drop at the maximum air flowrate across the filter when the filter needs replacement per ASHRAE Standard 52.1).

- OperationTemperatureRange
  P_BOUNDEDVALUE / IfcThermodynamicTemperatureMeasure

  | OperationTemperatureRange: Allowable operation ambient fluid temperature range.

- FlowRateRange
  P_BOUNDEDVALUE / IfcVolumetricFlowRateMeasure

  | FlowRateRange: Possible range of fluid flowrate that can be delivered.

- NominalFilterFaceVelocity
  P_SINGLEVALUE / IfcLinearVelocityMeasure

  | NominalFilterFaceVelocity: Filter face velocity.

- NominalMediaSurfaceVelocity
  P_SINGLEVALUE / IfcLinearVelocityMeasure

  | NominalMediaSurfaceVelocity: Average fluid velocity at the media surface.

- NominalPressureDrop
  P_SINGLEVALUE / IfcPressureMeasure

  | NominalPressureDrop: Total pressure drop across the filter.

- NominalFlowrate
  P_SINGLEVALUE / IfcVolumetricFlowRateMeasure

  | NominalFlowrate: Nominal fluid flow rate through the filter.

- NominalParticleGeometricMeanDiameter
  P_SINGLEVALUE / IfcPositiveLengthMeasure

  | NominalParticleGeometricMeanDiameter: Particle geometric mean diameter associated with nominal efficiency.

- NominalParticleGeometricStandardDeviation
  P_SINGLEVALUE / IfcReal

  | NominalParticleGeometricStandardDeviation: Particle geometric standard deviation associated with nominal efficiency.
