Trace 700 - VAV Reheat with Baseboard Heating

Good Morning,

We are new users of Trace and are immediately up against an issue.
We are modeling a building with VAV reheats and a dedicated OA unit,
which is fine. But we also have baseboard heat to combat leaky
single pane wood windows (historic). Trace doesn't allow two systems
to be assigned to a room or zone. Is there any way to model this?

Any help would be appreciated.
Thanks in advance.

You may use VAV w/Baseboard Heating or VAV Reheat(30% Min Flow Default). However, you probably can't have both VAV reheat coil and baseboard heating in one system. I think it doesn't matter though, since the heating load from the window will ultimately be provided by central plant , such as boiler. For TRACE, whether this envelope heating load is addressed by finned tube or VAV reheat coil will be the same for Boiler and Pump as central plant level.

You can also call TRACE tech support. They are very experienced and probably can give you more suggestions.
