| Name | Property Type | Data Type | Description | |
|---|---|---|---|---|
| Value | IfcPropertyReferenceValue | IfcTimeSeries |
The expected range and default value. Indicates sensed values over time which may be recorded continuously or only when changed beyond a particular deadband. The range of possible values is defined by the SetPoint property of the corresponding sensor type property set. |
|
| Direction | IfcPropertyReferenceValue | IfcTimeSeries |
Indicates sensed direction for sensors capturing magnitude and direction measured from True North (0 degrees) in a clockwise direction. |
|
| Quality | IfcPropertyReferenceValue | IfcTimeSeries |
Indicates the quality of measurement or failure condition, which may be further qualified by the Status. True: measured values are considered reliable; False: measured values are considered not reliable (i.e. a fault has been detected); Unknown: reliability of values is uncertain. |
|
| Status | IfcPropertyReferenceValue | IfcTimeSeries |
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). |
