Note: The packages whose name ends with Beta are still being validated.

The following critical error has been fixed (i.e. error that can lead to wrong simulation results):

Buildings.RoomsBeta
Buildings.RoomsBeta.BaseClasses.InfraredRadiationExchange The model Buildings.RoomsBeta.BaseClasses.InfraredRadiationExchange had an error in the view factor approximation. The error caused too much radiosity to flow from large to small surfaces because the law of reciprocity for view factors was not satisfied. This led to low surface temperatures if a surface had a large area compared to other surfaces. The bug has been fixed by rewriting the view factor calculation.

The following improvements and additions have been made:

The following critical error has been fixed (i.e. error
that can lead to wrong simulation results):

Buildings.Fluid.Storage.
Buildings.Fluid.Storage.StratifiedEnhanced The model Buildings.Fluid.Storage.BaseClasses.Stratifier had a sign error that lead to a wrong energy balance. The model that was affected by this error is Buildings.Fluid.Storage.StratifiedEnhanced. The model Buildings.Fluid.Storage.Stratified was not affected.
The bug has been fixed by using the newly introduced model Buildings.Fluid.Storage.BaseClasses.ThirdOrderStratifier. This model uses a third-order upwind scheme to reduce the numerical dissipation instead of the correction term that was used in Buildings.Fluid.Storage.BaseClasses.Stratifier. The model Buildings.Fluid.Storage.BaseClasses.Stratifier has been removed since it also led to significant overshoot in temperatures when the stratification was pronounced.

New in this version are models for two and three way valves.
In addition, the Fluids package has been slightly revised.
The package Fluid.BaseClasses has been added because in
the previous version, partial models for fixed resistances 
where part of the Actuator package.

First release of the library.

This version contains basic models for modeling building HVAC systems. It also contains new medium models in the package Buildings.Media. These medium models have simpler property functions than the ones from Modelica.Media. For example, there is medium model with constant heat capacity which is often sufficiently accurate for building HVAC simulation, in contrast to the more detailed models from Modelica.Media that are valid in a larger temperature range, at the expense of introducing non-linearities due to the medium properties.
