| Buildings.Examples.VAVReheat | |
| Buildings.Examples.VAVReheat.ASHRAE2006 Buildings.Examples.VAVReheat.Guideline36 Buildings.Examples.VAVReheat.BaseClasses.PartialOpenLoop |
Changed models to include the hydraulic
configurations of the cooling coil, heating coil and VAV terminal
box. Changed heating supply water temperature at design condition to 45°C. Corrected implementation of freeze protection for ASHRAE 2006 models. This is for #2594. Changed model structure to separate building and HVAC system. This is for #2652. Changed parameter declarations and added to Guideline 36 models the optimal start up calculation. This is for issue #2829. |
| Buildings.Examples.ScalableBenchmarks | |
| Buildings.Examples.ScalableBenchmarks.BuildingVAV.ThermalZones.ThermalZone | Reimplemented computation of energy provided by
HVAC system to also include the latent load. The new implementation
uses the enthalpy sensor, and therefore the mass flow rate and
temperature sensors have been removed. Also, rather than load in
Watts, it outputs the energy in Joules. This version also improves the infiltration. Now, exactly the same amount of air in infiltrated and exfiltrated. This was not the case previously because the infiltration was a prescribed air flow rate, and the exfiltration was based on pressure difference. This caused an inbalance in the HVAC supply and return air flow rate. |

Changed implementation of the filter and changed
the parameter order to be a constant because typical
users have no need to change this value. The new implementation
uses a simpler model.This is for IBPSA #1498. This change is only backwards incompatible if a user propagated the value of order to a high-level parameter. |
| Buildings.Fluid.FixedResistances | |
|
Buildings.Fluid.FixedResistances.PlugFlowPipe Buildings.Fluid.FixedResistances.BaseClasses.PlugFlowCore |
In
Buildings.Fluid.FixedResistances.PlugFlowPipe, changed
ports_b, which was a vectorized port, to
port_b which is a scalar port. This has been done in
order for the model to have the same connectors as are used for
other pipe models.Refactored implementation and made various classes in this model protected. This is for IBPSA #1494. For Dymola, a conversion script renames existing models to Buildings.Obsolete.Fluid.FixedResistances.PlugFlowPipe

| Buildings.ThermalZones.EnergyPlus_9_6_0 | |
| Buildings.ThermalZones.EnergyPlus_9_6_0 | Renamed package to add the version number for
EnergyPlus. This will allow supporting more than one version of
EnergyPlus. This is for #2851. |
| Buildings.ThermalZones.EnergyPlus_9_6_0.Building | This model, which needs to be part of every model
that uses EnergyPlus, now requires the specification of the
EnergyPlus weather data file (.epw file) through the
parameter epwName.This is for #2443. Removed the parameters showWeatherData and
generatePortableFMU. Now, the weather data bus is
always enabled as it is used in almost all simulations. This change
is supported in the conversion script.Converted usePrecompiledFMU and the associated
fmuName from parameter to a constant as these are only
used for debugging by developers.This is for #2759. |

| Buildings.Occupants | |
| Buildings.Occupants.Office.Occupancy.Wang2005Occupancy | Reformulated model so it works also if the
simulation does not start at 0. To improve efficiency, this reformulation also changes the event triggering function so that it leads to time events rather than state events. This is for #2590. |
The following uncritical errors have been fixed (i.e., errors that do not lead to wrong simulation results, e.g., units are wrong or errors in documentation):
| Buildings.Airflow | |

Corrected wrong documentation string for surface area which should be gross rather than net area. |
| Buildings.Experimental | |
| Buildings.DHC.Plants.Cooling.Controls.ChillerStage | Corrected parameter value for
twoOn.nOut. This correction is required to simulate
the model in Dymola 2022 if the model has been updated to MSL
4.0.0. With MSL 3.2.3, the simulation works without this
correction.This is for Buildings, #1563. |
| Buildings.Media | |
| Buildings.Media.Specialized.Water.TemperatureDependentDensity | Corrected assignment of gas constant which lead to
a unit error. This change does not affect the results as the value
