Hello everyone!

I am currently working on a DOASVFR system design that only applies to a few zones, but cannot solve humidity problems. The DOASVFR system consumes much more energy than the VAV system, and has little effect on the cooling condition. Besides, the warnings keep reporting the not enclosed zone problems, even though I had already hard-sized the zone volume. Can I do anything to fix these problems?

 ** Warning ** CalculateZoneVolume: The Zone="ELCT ALL" is not fully enclosed. To be fully enclosed, each edge of a surface must also be an edge on one other surface.
 **   ~~~   **   The zone volume was calculated using the floor area times ceiling height method where the floor and ceiling are the same except for the z-coordinates.
 **   ~~~   **   The surface "SURFACE 863" has an edge that was used 4 times: it is an edge on three or more surfaces: 
 **   ~~~   **   The surface "SURFACE 1440" has an edge that was used 4 times: it is an edge on three or more surfaces: 
 **   ~~~   **     It was found on the following Surfaces: 'SURFACE 1441' 'SURFACE 1445' 'SURFACE 1446' 
 **   ~~~   **     Vertex start { 5.8000, 95.2500, 27.4000}
 **   ~~~   **     Vertex end   { 5.8000, 95.2500, 22.0000}
 **   ~~~   **   The surface "SURFACE 1441" has an edge that was used 4 times: it is an edge on three or more surfaces: 
 **   ~~~   **     It was found on the following Surfaces: 'SURFACE 1442' 'SURFACE 1445' 'SURFACE 1450' 
 **   ~~~   **     Vertex start { 5.8000, 95.2500, 27.4000}
 **   ~~~   **     Vertex end   { 5.8000, 91.8000, 27.4000}

This is my osm. filelink text.

I am a complete freshman in HVAC system design, and do not have many ideas about the parameters, like the design air flow or the equiments sizing.

Does anyone know how to solve the problem?

Thanks, any assistance would be greatly appreciated!

Sincerely, Peijun
