Internal
Overview
Provides internal design conditions/criteria for heat loss/gain and cooling calculation or analysis.
Results
Internal design criteria for various purposes that should be referenced using the information set qualifier as:
- (Heating)
- (Cooling)
| Description | Entity/Pset | MAN | REC | OPT |
|---|---|---|---|---|
| Specify the space to which the internal design criteria apply | IfcSpace | |||
| Depending on the calculation/analysis required, different sets of information may be required. These are grouped below as heating, cooling. | ||||
| *HEATING * | ||||
| Inside dry bulb temperature for heating design | Pset_SpaceThermalDesign.HeatingDryBulb IfcPropertySingleValue IfcThermodynamicTemperatureMeasure |
