In a multi tenant CS office building smoking is prohibited in the entire building (Option 1). However the owner wishes to execute a few single person offices as designated smoking rooms. All conditions such as deck to deck partition, pressure difference and blower door testing according to Option 2 will be met.
I am wondering, whether a single person office can be considered a designated smoking room?
While its occupant may be a smoker, it cannot be ruled out, that a non-smoking colleague (secretary) would need to enter this room for the purpose of her work.
Does anyone of you have experience with this case?
