This validation case simulates two instances of
Buildings.ThermalZones.EnergyPlus_24_2_0.Examples.SingleFamilyHouse.Unconditioned.
In the instance mulCap, the case is modified by adding
the following snippet to the idf file:
ZoneCapacitanceMultiplier:ResearchSpecial,
    Living zone heat capacitance multiplier,  !- Name
    LIVING ZONE,                              !- Zone or ZoneList Name
    10,                                       !- Temperature Capacity Multiplier
     ,                                        !- Humidity Capacity Multiplier
     ,                                        !- Carbon Dioxide Capacity Multiplier
     ;                                        !- Generic Contaminant Capacity Multiplier
This model is to validate that this leads to a difference in the simulation results as expected.
