Hello, This is our first Core & Shell project and we have a tenant ready for a two story commercial space. The entire project is being designed with the tenant in mind due to their relationship with the owner/developer. The first floor commercial space is currently unknown. Can we incorporate all of the MEP items of the tenant space as part of our certification process, or do we have to draw the line somewhere? I know that LEED leaves this a bit ambiguous for the range of projects out there,but its a bit too ambiguous.
In addition, if they are not to be included then what is to be modeled for the Core & Shell in terms of energy & water use? Do the mechanical systems have to be owner managed or can the specifics be outlined in an owner/tenant agreement?
Thanks

You can incorporate energy saving strategies in your model if they have been designed or if you have tenant guidelines that require certain levels of performance in the lease agreements. Tenant spaces without a design or tenant guidelines should be modeled identically to the baseline for those items to be designed or installed in the tenant fit out.

Thanks for your reply,
So if I understand correctly, we can assist our baseline model to meet LEED requirements for the core and shell with data designed and constructed from a tenant that will have a performance guideline in their lease. If this is correct, would the undesignated tenant have to have performance guidelines as well? Would either of them have to go LEED interiors or commercial? Thanks again!

You understand correctly. I do not think the other tenant space would be required to have the same requirements. Neither would have to get ID+C certified.

If I may add, the key to this is to carefully draw the distinction between what is tenant scope and what is base building scope. If the tenant interior spaces are undefined, the LEED submittal process and analysis needs to be consistent across all LEED credits. The base building needs to be modeled and in order to do that enough of the design needs to be carried out and commissioned in order to qualify for C&S. This goes for all systems: HVAC, lighting, lighting controls, and water fixtures. Whatever you plan to have commissioned also needs to be considered in all of the other EA and relevant IEQ credits.
If you know what the tenant spaces will look like and you have designed all of the branch systems and coordinated everything with the base building model, commissioning and other credits, then you might as well include it so that you don't have to carefully craft an imaginary division of work that I just described above.
Marcus is the expert here, but this is based on my own experience.

I agree Brian. If is it already designed that is the most accurate way to model it.
