Insulating Walk-out basement

Hello,

If at all possible, I'd like some assistance on how to insulate a walkout basement with foundation walls 50% above grade.

I've read through the Building Science recommendation of rigid foam being adhered to the foundation wall and if additional insulation is needed, adding unfaced butt insulation between the framing. However, I'm in unclear as to what the appropriate method is for walk-out basements since 50% of the foundation is above ground, which allows moisture to dry outward (above grade portion of foundation) as opposed to mostly inward (below grade).

Are there any suggestions or other references that anybody can point me toward?

Thanks
