Update to EnergyPlus 24.1.0, 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. Worked on tests and needs to wrap up distribution.
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.
Need peak zone loads, and for systems, the coinciding loads. This would require sending to EnergyPlus a string that shows to what system the zone belongs to. Needs design work. Sizing data must be parameters, following the same patter as is used for the zone volume.
Todo:
- Michael to design required data and write json snippet.
None.
Design auto-sizing integration.
None.
