NC-2009 EAp2: Minimum Energy Performance
In a recent LEED project, we face problems while setting up energy model for a complex design, in which there are 7 smal buildings based on a large underground garge. However, they are applied as a single LEED project.
We use EnergyPlus+OpenStudio to build the energy model. Could I set up these small buildings individually and then add the results up, or I have to set up all the small buildings at once?
Because the design is a bit complex...
Thanks for advice:)

A portion of our building envelope is historic. Can we exclude it from our model?
For an existing building, do I need to rotate the model?
Our process load is higher than 25%. Do we have to justify that?
Our local code references ASHRAE 90.1-2010. Should I use that for my documentation, or 90.1-2007?
Can mezzanines open to floors below be excluded from the energy model?

Generally, you can model each piece individually and add the results. However, if they are served by common equipment (say one chiller plant serves all the buildings) you want to be careful that you are modeling the actual equipment performance. You don't want 5 models each showing the chiller running at 15% capacity, when it is actually running at 75% capacity, as these will have different points on the efficiency curve.
