AOP alignment

LBNL: 3/30/25, Released Modelica Buildings Library with template for combined chiller and heat pump plants with storage and heat recovery chiller, and with updated EnergyPlus v 24.2 coupling.

LBNL: 4/30/25, Modelica Buildings Library ready for first OpenStudio workflow from Spawn that includes an auto-sized HVAC system.

Sizing

Draft specification at https://lbl-srg.github.io/soep/softwareArchitecture.html.

Next time, see if DesignSpecification:OutdoorAir:SpaceList should cause the idf to be rejected.
