Buildings.ThermalZones.EnergyPlus_9_6_0.Validation.ThermalZone.Infiltration

Validation model for outside air infiltration in zones not modeled in Modelica

Information

This validation case simulates two instances of Buildings.ThermalZones.EnergyPlus_9_6_0.Examples.SingleFamilyHouse.RadiantHeatingCooling_TRoom. In the instance higInf, the infiltration rate of the unconditioned attic has been significantly increased. This leads to a different surface temperature of the attic floor, which can be shown by comparing the variables defInf.attFlo.heaPorFro.T and higInf.attFlo.heaPorFro.T.

Buildings.ThermalZones.EnergyPlus_9_6_0.Validation.ThermalZone.InternalGain

Validation model for one zone with and without internal heat gain

Information

Simple test case for one building with one thermal zone with different inputs for the internal heat gains.

Extends from Modelica.Icons.Example (Icon for runnable examples).

Modelica definition

Buildings.ThermalZones.EnergyPlus_9_6_0.Validation.ThermalZone.OneZoneCompareZoneTemperatureOutput

This example tests whether the zone mean air temperature is reported correctly as an EnergyPlus output

Information

Simple test case that verifies whether the zone mean air temperature is reported correctly by EnergyPlus. Note that Modelica solves the differential equation for this variable, but this test case obtains its value from EnergyPlus.

Extends from Buildings.ThermalZones.EnergyPlus_9_6_0.Examples.SingleFamilyHouse.Unconditioned (Example model with one unconditoned zone simulated in Modelica, and the other two unconditioned zones simulated in EnergyPlus).

Parameters

Modelica definition

Buildings.ThermalZones.EnergyPlus_9_6_0.Validation.ThermalZone.OneZoneOneYear

Validation model for one zone

Information

Simple test case that simulates a building with one thermal zone for one year.

Extends from Buildings.ThermalZones.EnergyPlus_9_6_0.Examples.SingleFamilyHouse.Unconditioned (Example model with one unconditoned zone simulated in Modelica, and the other two unconditioned zones simulated in EnergyPlus).

Parameters

Modelica definition

Buildings.ThermalZones.EnergyPlus_9_6_0.Validation.ThermalZone.RefBldgSmallOffice

Validation model for six zones small office building

Information

Validation of free floating temperatures. The model uses the small office building of the DOE Reference Buildings. The Modelica model is in free floating mode, and the data reader datRea outputs, for comparison, the free floating room temperatures that were obtained from an EnergyPlus simulation.

Modelica definition

Buildings.ThermalZones.EnergyPlus_9_6_0.Validation.ThermalZone.TwoIdenticalZones

Validation model with two identical zones

Information

Model with two identical thermal zones that validates that they yield the same indoor air temperatures and humidity, and that these results are close to the values computed by EnergyPlus.

Each zone has a floor area of 900 m², the same door and two windows on the south side. The internal gains for lighting, people and equipment are identical. The zones are detached and do not shade each other. The zones have an outside air exchange rate of 0.3 air changes per hour.

Buildings.ThermalZones.EnergyPlus_9_6_0.Validation.ThermalZone.ZoneCapacitanceMultiplier

Validation model for zone capacitance multiplier in Spawn

Information

This validation case simulates two instances of Buildings.ThermalZones.EnergyPlus_9_6_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.
