LBNL: 9/30/26: Released Modelica Buildings Library with additional models for high performance heating and cooling plants, and with HVAC auto-sizing capability based on automated EnergyPlus load calculation
Draft specification at https://lbl-srg.github.io/soep/softwareArchitecture.html.
Documentation is updated. Examples are running. One item to add is a parameter in Modelica for zone infiltration, as currently infiltration is not regarded.
Once that is done, it is close to be wrapped up and merged.
Tough coupling, correct race condition. https://github.com/lbl-srg/modelica-buildings/pull/3696
Backlog on fixing various issue, focus on https://github.com/lbl-srg/modelica-buildings/milestone/30
Block "summary" with main variables.
PNNL priority is zone side templates.
PNNL has milestones for end of FY to implement heat pump water heater, mostly using existing classes. Karthik works on finishing it for the PR.
Finish DX dehumidifier. Jianjun to update model, see review comments. https://github.com/lbl-srg/modelica-buildings/pull/3475
Finish direct evaporative cooler. Karthik to address feedback. https://github.com/lbl-srg/modelica-buildings/pull/3755
