We actually construct a high rise office building with commercial area at the first level. One of our projected commercial tenant want to modify his frontage, that we previously made, by adding new entrance. Initially this area was served by one entrance. This entrance is in conformity with the mandatory provision of ashrae 90.1 2007 5.4.3.4 "Vestibule". His new entrance will not have vestibule and thus, will not be in conformity with ashrae mandatory provsion. It is a CS project. Is it of our responsability to impose to the futur tenant to respect the mandatory provisions of ashrae 90.1, and thus, imposed a vestibule?
Thank you.

Do any of the exceptions to this provision apply?
If not then it appears as if a vestibule would be required according to 90.1.

No exception can be applied. Thanks a lot for your answer.
