Hi,
We are working with a project that is not constructed yet (office building, Core and Shell). The building volume and facades have been decided, but the exact plan layout is not known yet, as the interior design will depend on the tenant.
We need to acquire Daylight credits, which requires that there is a defined “regularly occupied space”. We know that the regularly occupied spaces will be distributed on the perimeter of the floor plan, but we don't know whether they will be open plan or cell type. Which is the process that we must follow in order to specify a reasonable plan layout that is acceptable by LEED? For instance, could we make an assumption that the occupied space consists of cell offices across the perimeter of the floor plan, with a certain depth from the facade (3.6m)? We know that if the offices are eventually designed as open plan offices, this depth will be the same.
Thank you in advance

In case this is still useful for your project: In a past Core & Shell project a reviewer asked us to provide a potential office layout for a typical floor. The documentation was thus similar to a fully built-out BD&C NC project. They didn't give us any specific requirements for the office layout, but it needed to be realistic. It seems reasonable to use a floor plan with a open offices around the perimeter with meeting rooms and any private offices toward the core.

David - I've seen that working for Views but for Daylight the LEED v4.1 Reference Guide provides guidance for CS projects. For Option 1 and Option 2 it states, "Assume that the entire floor plate, except for the core, will be regularly occupied space." We find this pretty challenging to achieve for CS projects.
