OpenStudio integration

FMI-QSS

No discussion.

Modelica Buildings Library

Various issues fixed.

Working on library release.

PNNL presented implementation of heat pump water heater. High level items to consider

  • can number of nodes in tank be reduced
  • check what data record can be defaulted so that only published data need to be used to configure model
  • check if COP and EIR curves can be automatically converted (perhaps via the polynominal support points) to allow the same data as is used in EnergyPlus
  • make graphic bigger to avoid less crowded diagram

EnergyPlus-Modelica coupling

Spawn related PR at https://github.com/lbl-srg/modelica-buildings/projects/2

Update to EnergyPlus 23.1.0, after 10.0.0 release and fixes of some spawn issues below.

Issues are at https://github.com/lbl-srg/modelica-buildings/issues?q=is%3Aissue+is%3Aopen+label%3Aspawn

Next, work on https://github.com/lbl-srg/modelica-buildings/projects/2

OS compatibility matrix is at https://github.com/NREL/OpenStudio/wiki/OpenStudio-SDK-Version-Compatibility-Matrix

Kyle to work on the Spawn issues.

Negative start time, start day of the week, and initialization for non-zero start time are handled as one fix as they are somewhat related.

What if startTime is changed programmatically? EnergyPlus start time corresponds to Jan 1, e.g., Modelica time 0. For users, RunPeriod user entries of original idf file are ignored.
