Version 10.0.0

[mwetter]

Version 10.0.0 is a major release that adds various new packages and models.

The library has been tested Dymola 2023x, OpenModelica 1.22.0-dev (41-g8a5b18f-1), OPTIMICA 1.43.4 and recent versions of Impact.

The following major changes have been done compared to release 9.1.1:

• A package with configurable template models for variable air volume flow systems with control based on ASHRAE Guideline 36 has been added to Buildings.Template.
• Reduced order building envelope models based on the ISO 13790:2008 Standard have been added. This allows modeling of building envelope heat transfer either with a detailed Modelica multizone model (Buildings.ThermalZones.Detailed), with EnergyPlus via the Spawn coupling (Buildings.ThermalZones.EnergyPlus_9_6_0), or with reduced order models based on ISO 13790 (Buildings.ThermalZones.ISO13790) or based on VDI 6007 (Buildings.ThermalZones.ReducedOrder).
• Various models for district energy systems have been added to the package Buildings.Experimental. This package includes models for
  • combined heating and cooling district energy systems that operate near ambient temperature (sometimes called 5th generation district energy systems),
  • Energy Transfer Stations (ETS) with all electric plants with heat recovery chillers,
  • ETS with multiple heat pumps (heat recovery as well as air-source heat pumps) and storage, i.e., the so-called Time-Independent Energy Recovery (TIER) plant in (Buildings.Experimental.DHC.Plants.Combined.AllElectricCWStorage),
  • direct and indirect ETS for heating or for cooling, and
  • district steam systems.
• A package with all major hydronic configurations that are encountered in heating and cooling systems has been added in Buildings.Fluid.HydronicConfigurations. This package also includes automatic sizing of control valves to obtain suitable valve authority.
• The fan and pump models have been revised, and can now be configured to compute the part load efficiency based on the Euler number.
• Various new elementary control blocks have been added to the Buildings.Controls.OBC.CDL package to provide a reference implementation of the ASHRAE Standard 231P Control Description Language that is currently being developed. See also obc.lbl.gov.
