[Bldg-sim] equest zoning approaches

[Rimes, Christie]

Ideally it would be option one as this would be easiest for both modeler and reviewer, however more and more it is becoming option two. Here are a few reasons why:
 - If the LEED model has been developed in DD the architectural layouts could change. It is therefore easier to provide more rooms in the model so that layout changes are easier to deal with without having to redo the model
 - Space by Space method lighting requires the modeling of storage rooms etc
 - The few building I have worked on for LEED have primarily perimeter spaces. Therefore it is harder to clump like rooms together due to orientation differences.
 - To accurately model the building area it is easier to model some unconditioned spaces so that these can be included or taken out of the area calcs. 
 - To more accurately model VAV boxes zones need to be broken out

Subject: [Bldg-sim] equest zoning approaches

I am wondering how the typical equest model is zoned.  Two scenarios:

1.  Create a zoning diagram combining like spaces on perimeters and like spaces in interiors based on the HVAC type and distribution.  Combine storage rooms with exhaust only with adjacent space where the transfer air comes from, etc.  Plunk this zoning diagram into equest.

2.  Plunk the architectural drawing into equest and every space becomes an equest space - every closet, elevator/duct shaft, office, small interior meeting room, janitor closets - all a space in equest.

I had always assumed that the scenario 1 would be used.  I am now finding (by way of reviewing LEED submissions) that many people use scenario 2.  It seems very inefficient to me and certainly increases the cost of doing a review.

What is typical?
