Hi everyone,

We are currently working on a Core & Shell project and in terms of HVAC equipment it will comprise VRF units with indoor FCUs. However, the MEP scope of design at this stage includes only the outdoor VRF units; hence no information for the FCUs will be provided. The FCUs and all the remaining HVAC equipment shall be designed at a tenant level at a later stage.

Would you please advise on what approach we should be using for the energy model? We will incorporate the data provided for the outdoor VRF units, but what should we do in terms of the indoor units? Would it be acceptable to run the autosize on IES VE and keep the capacities determined by the software?

Thank you.

Kind regards,

Nikos
