|
| DryBulbTemperatureHistory | IfcPropertyReferenceValue | IfcTimeSeries |
Loads from the dry bulb temperature. |
|
| RelativeHumidityHistory | IfcPropertyReferenceValue | IfcTimeSeries |
Loads from the relative humidity. |
|
| InfiltrationSensibleHistory | IfcPropertyReferenceValue | IfcTimeSeries |
Heat gains and losses from infiltration. |
|
| TotalSensibleLoadHistory | IfcPropertyReferenceValue | IfcTimeSeries |
Total energy added or removed from air that affects its temperature. If a value is less than zero (negative), then the thermal load is lost from the space. If a value is greater than zero (positive), then the thermal load is a gain to the space. |
|
| TotalLatentLoadHistory | IfcPropertyReferenceValue | IfcTimeSeries |
Total energy added or removed from air that affects its humidity or concentration of water vapor. If a value is less than zero (negative), then the thermal load is lost from the space. If a value is greater than zero (positive), then the thermal load is a gain to the space. |
|
| TotalRadiantLoadHistory | IfcPropertyReferenceValue | IfcTimeSeries |
Total electromagnetic energy added or removed by emission or absorption. If a value is less than zero (negative), then the thermal load is lost from the space. If a value is greater than zero (positive), then the thermal load is a gain to the space. |
