All,

I am presently modeling a residential building in Equest. The baseline
system is PTACs. The building will have Natural Ventilation. No matter
what I do, natural ventilation is not available for PTACs. Per DOE-2...

The following "VENT" keywords apply to natural ventilation through open
windows. They apply only to system TYPE = RESYS, RESYS2, PSZ, PVVT and
EVAP-COOL.

Is this a fatal flaw with Equest? Has anyone found a work around? My only
solution is to change the system type to RESYS.

Any ideas would be appreciated.
