IfcPerformanceHistory: public Ifc2x3::IfcControl¶
IfcPerformanceHistory is used to document the actual performance of an occurrence instance over time. In practice, performance-related data are generally not easy to obtain as they can originate from different sources (predicted, simulated, or measured) and occur during different stages of the building life-cycle. Such time-related data cover a large spectrum, including meteorological data, schedules, operational status measurements, trend reports, etc.
HISTORY: New entity in Release IFC2x Edition 2.
Describes the applicable building life-cycle phase. Typical values should be DESIGNDEVELOPMENT, SCHEMATICDEVELOPMENT, CONSTRUCTIONDOCUMENT, CONSTRUCTION, ASBUILT, COMMISSIONING, OPERATION, etc.
