Yes. ASHRAE Standard 90.1, Table G3.1, No. 7 describes the conditions that must be met to allow creating a thermal block from different HVAC zones. Condition c. is "All of the zones are served by the same HVAC system or by the same kind of HVAC system."

Will combining the areas work for a LEED model?

I agree with Bill.

If you intend split the zone regardless in detailed edits, the attached illustrated guide from some time back may prove useful =).

Stephanie,

If the RTUs are identical, or at least of similar efficiency, my preference would be to combine their capacities, airflows etc. and model them as one unit/system. It is possible, but time-consuming to add zones once you have made changes in DD Edit mode. Be sure to Save-As the model to work from a new copy if you experiment with modifying the geometry/zones in DD Edit mode.

Regards,
Bill

Subject: [Equest-users] Splitting Zones

All,

I'm needing to split one thermal zone into 2 thermal zones. Originally the whole space was to be conditioned by one rooftop unit, and now we have 2 units serving the space. Is it possible to split a space in half?

Thanks!
