I’m modeling a hotel (5 storey, one floor is underground) in which there are also offices, a coffee bar, a wellness center... I read that “hotel/motel guest rooms” are among the residential spaces. Definition of “residential”: "spaces in buildings used primarily for living and sleeping. Residential spaces include (..) hotel/motel guest rooms".
In the baseline model shall all the envelope components have the U-factor relative to “residential” (Tab. 5.5), since the rooms are the primary use? Even in the wellness center or in the offices?
Best Regards

Technically you are supposed to model the residential spaces with the residential requirements and the non-residential with those requirements. If the wall area of the non-residential is very small (less than 5%) you don't have to model the non-residential spaces separately.

Thank you, Marcus. Is the limit of 5% a recommendation of ASHRAE 90.1?
