In a mixed use building like yours, it's quite common to have ground floor retail space that's only built as core and shell at the time of certification. You'll want to include these areas in both the daylight and views calcs - with storefront glazing, there's often alot of daylight.
For drawings & calcs, one approach would be showing the likely demising walls between tenants, and then draw a average back-of-house storage/ work room. With that as your typical space plan, you can draw your floor/ glazing area take-offs and lines of sight.
