So we are facing a new Commercial Interior project that only takes up approximately half of a floor. The problem we are facing is if we can conduct an energy model for half of floor. The space is mostly enclosed with access to the space provided by a set of double doors in the main corridor.
For the energy model, do we generate the model for just the footprint of the project space and classify the border by the double doors as adiabatic, or should we model the entire floor and classify the non-project space as neutral?

I would go the adibatic route. Especially if the space has its own isolated HVAC systems.

The space has its own AHU, but it is still using perimeter hot water radiators which is distributed to the entire floor for all the floors from a base building HW boiler plant. Should we then go to modeling the entire floor instead of going adiabatic?

I would look at the Reference Guide relative to how you include central building systems in your model. I believe that you can create a virtual plant so modeling the whole floor would not really make a difference.
