modelCase430
Extends from AixLib.ThermalZones.HighOrder.Validation.ASHRAE140.Case420.
Information
Input Specifications of Case 430 as described in ASHRAE Standard 140:
Difference to case 420:
- Solar absorptance on exterior surface = 0.6
Limitations
The simulated annual cooling load of Case 430 cannot meet the
statistical acceptance ranges given by ASHRAE140 (01.01.2021).
However, cases that do not perform according to the reference values
should not be considered erroneous. They shall be used as indication
for debugging purposes instead.
