We have a mixed use project that has retail and speculative (office) space.
The retail is out of the certification.
I have some trouble filling out PIf3-1 space usage types. The retail area will be out of this table since it is not pursuing LEED certification (it's MEP systems are indepentend from the speculative space), but I don't know if I should split the speculative office space into office, circulation and storage since there are some storage rooms and we have corridors on the elevator lobbies.
I think I should just go for office space and include everything except the retail space, but I'm not sure if this is correct.
Does anyone have any experience about this? Thank you so much.

It might help to think in terms of "gross square footage" and what support spaces are included in the gsf of the office space: circulation, restrooms, mechanical rooms and storage on an office floor is usually included, so you don’t need to split those out into their own space name rows. Structured parking would not be included.
Since the sf of “Regularly occupied area” is linked to the IEQc8 Daylight and Views credits, it’s common to exclude those support spaces in that column and list a number more like the net square footage for that column of the table. Once you get to the EQc8 credit forms, you still have another chance to indicate the area of regularly occupied space that needs daylight, which often excludes specific spaces such as copy rooms, file rooms, server rooms, etc.
Since you have a core & shell situation where you might not have that level of detail, you could probably use the office space gsf for the Gross Area column and then assume 85% of that will be net sf for the Regularly Occupied Area column. Unconditioned Area might be vertical shafts.
In general, it’s less important to be extremely precise in your calculations and sub-areas, and more important to be consistent across the forms.
