Green Building Q&A: Above Grade Exterior Foundation Insulation

I am planning to build an energy efficient home in eastern PA. The basement walls will be poured concrete with R-10, 2" thick rigid foam board installed on the exterior wall below grade with a "Delta MS Exterior Membrane Installed between the rigid foam and the foundation wall. (Drainage plane is needed because of high water table on my building lot.) I would like to insulate the exposed, above grade foundation wall at R-10 to satisfy code rather than. installing the insulation on the interior wall.

Any creative solutions for accomplishing the exterior insulation other than going with a Superior Wall System?
