We request for a clarification regarding mandating the tenant to use the VAV boxes in core and shell projects.
In a core and shell project, we will not know what system the tenant will be using. Is it right, if we use the same HVAC system as in baseline case for tenant areas?
If the project has a VAV with PFP boxes in baseline case, can the proposed case air side system be identical to baseline case? Do we have to mandate the VAV distribution to the tenants through tenant lease agreement?
Thank you

If the HVAC in the tenant spaces has not been designed then you model the HVAC in those spaces identical to the baseline system. No need for a requirement in the tenant lease agreement. You only need a requirement in the tenant lease agreement if you are attempting to claim any savings over the baseline. Modeling the proposed identical to the baseline does not require the tenant to install VAV, it just makes the HVAC neutral so it does not contribute to any energy savings.
