Revision history [back]

I'm modelling a small building that has supply air directly to some zones, transfer air to the rest, and extraction from all zones - which then goes through an HRV. I want to keep rooms as separate zones in order to model some comfort issues that have come up.

The current model is in Energy Plus. I could create a full network manually, just hoping to find a faster way. Any suggestions for how to model this with HVAC templates? Perhaps with some editing of the expanded IDF? Would Open Studio have better tools for this type of model?

The building has similarities to a passive house (supply air in some zones, return from others). How are those typically modeled with E+ / OS?

EDIT:

The simplest form would be something like this. this (this just shows the general flow, not all elements of the air loop). I now have a model of this that seems to work where I created a duct branch from the Zone 1 return air node to the Zone 2 air inlet node. The CO2 concentrations are as expected (much higher in Zone 2), but the air temp is almost the same in the two zones so I'm trying to isolate other factors.
