I could both very general and very specific guidance on modeling a mixed-use project - with first floor retails space that is "shell" only (tenant build-out is not included in the project) and three floors of residential (apartments) above.

Generally - how do I handle the energy modeling of the first floor? We are doing the project under NC 2009 because it is >75% NC (25% core and shell).

Specifically what values do I use for basecase LPD for the first floor "core & shell" space and

What type of mechanical system design should I use for basecase and proposed?

If I need to start over with a new question under the Core and Shell ratings

Thank you.
