[Bldg-sim] Multiple Buildings

[David S Eldridge]

A few things to consider:
Are the buildings part of the same project or building permit? - if separate then 90.1 would apply to them individually.  This is regardless of grouping them into one LEED project for instance.
The definition of "building" in 90.1-2004 is "a structure wholly or partially enclosed within exterior walls..." - so even if combined into one building permit, these three might be treated as separate buildings for system selection purposes, especially if the predominant usage for the three is different based on Exception (a) to G3.1.1 (assuming  you are using the Performance Rating Method and not ECB since you are discussing the building sizes).
Hope this helps, good luck!

All;

I have a project with multiple buildings on one site to model.  When determining the correct baseline HVAC system, should I do this on an individual building basis, or use the same system for all buildings and base it on the summation of all of the buildings' areas?

The first building is 3-stories and 190,000 square feet, the second building is 1 story and 44,000 square feet, and the third building is 1 story and 8,000 square feet.

I have tried searching old posts with no success.  Thanks for your help.

Scott
