Commercial (A-3) exterior door U value

We are replacing an existing exterior door and moving it 3-feet in at the local VFW post (A-3) and the building official wants the Building and Energy Code noted (OZERCC) and the U value of the door, which i believe is U0.700. (please confirm). This seems a bit .....excessive. I have been scouring the OZERCC and cannot view chapter 13 of the OSSC that states the U value of elements. This is a very minor alteration to the post and i feel the plans examiner is being a bit overzealous. Can you help?

The manufacturer supplies to provided specifications and the city is closed and plans examiners seldom if ever respond. I was hoping for a little assistance from another professional. Clearly you don't know or are unwilling to assist. No worries. If there is anyone else who can assist I would appreciate it. cheers.

The OZERCC requires compliance with ASHRAE Standard 90.1-2016. Unfortunately, I do not have a copy of the 2016, but I do have a 2013 edition, which requires a U-0.50 for opaque swinging doors in Climate Zones 4 and 5 (Zone 4 along the coast and Zone 5 for the rest of Oregon). A standard hollow metal door can have U-factors ranging from U-0.50 to U-0.36, so you should have no problem finding a door that complies. If the door is a glazed aluminum entrance door, the required U-factor is U-0.77 for Climate Zones 4 and 5. Depending on the type of glass used, you should have no problem finding a glazed aluminum door that complies.
