See if you can find information in ASHRAE 90.1. Also see attached .pdf

We  are planning for two wall types.  The lower level walls will be either 12-inch masonry foundation wall or a 12-inch basement wall.  Each wall type will include brick veneer and 2-inch continuous rigid insulation.  The upper level exterior wall is load-bearing metal studs with 6-inch faced batt insulation in stud cavity, sheathing, 2-inch continuous rigid insulation, air space and face brick.

As I consider a shelf for my brick veneer to sit on, I realize that I will not be able to align the 2-inch rigid insulation between building levels.

Is it acceptable to offset the insulation by a couple inches, or somehow consider locating the continuous insulation on the interior face of the basement walls?  If offseting is allowed, do they need to overlap by some amount?
