I have an existing building envelope that contains two tenancies.
One tenancy is to be renovated and this involves two changes to the existing building envelope.
One is where a double entry door is added into an existing run of storefront.
The other is cutting an opening in the rear wall to install an exit door.
Question is of how to address this per IECC 2015.
Upgrade the whole building envelope just because of the addition of these two doors? (30 year old building)
Or just apply prescriptive requirements to these two new doors?
Or is the addition of the two doors minimal enough to consider that the building envelope is not being changed?
