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:)
