Consider how LEED-CS prerequisites impact tenant fit-outs and communicate this to tenants before build-out. For example: 

Many tenant spaces use publicly available restrooms and have little control over the water efficiency of their space. If your CS building provides efficient water fixtures, this helps them in earning WEp1: Water Use Reduction. Let them know the flow- and flush-rates of all applicable fixtures. 
Depending on the scope of the core-and-shell building, you may also need to inform the tenants of any HVAC equipment energy and ventilation parameters that your LEED-CS project met. 
Depending on which of the two options you’ve chosen for IEQp2: Environmental Tobacco Smoke Control, you could either have a simple tenant-non-smoking policy or need for the tenant to install a compliant HVAC design.
