Anticipated Tenant Fit Out and IEQ compliance

Background: In a C&S building we suggest a Tenant fit out to comply with credit IEQ_c8.2, where we show meeting rooms, corridors and an office space layout resulting in a grater quantity of people of that responding to the "default occupancy". The questions are: 1. Do we have to consider this layout for the PIForms? 2. Do we have to consider this quantity of people for every other credit and prerequisite?, including de FTE? 3. Do lighting savings have to account for the different spaces like corridors in the lighting power allowed calculations? Thank you
