Greetings, We're doing a CI project where the glazing far surpasses the 40% wall area allowed on the north wall. However, the envelope will not be altered for this project. Does this mean we do not have to comply with sections 5.4 and 5.5?

Correct - existing conditions do not have to be upgraded.

In a project where the existing storefront is not being altered, except for 2 entry/exit glass doors that needed to be enlarged, do the doors have to meet ASHRAE Mandatory Provisions in 5.4, or since the overall scope of work excludes major envelope changes, is it still considered outside of scope?

If you are replacing the doors I think they would have to comply with the mandatory provisions.
