Here in NC
(for everybody else), code energy requirements have been rolled back to IBC 2009 standards by the home builder lobby. Although their argument has been that better codes degrade "affordable housing," this really just shifts the initial costs of better construction to home owner operational costs in repairs and higher energy bills from being barely code compliant. So-called affordable is actually more expensive beyond the first year or two.
The other responses here look to have you on the right path. But I recommend you (all architects, frankly) become familiar with the excellent body of building science research relating to these kinds of questions that is accumulating around the web at places like Green Building Advisor, Fine Home Building, Building Science Corporation, Matt Risinger (YouTube), and Energy Vanguard.
I believe architects should provide better design than is available through the more common avenues. It is low hanging fruit to understand building science and offer its value to the marketplace. Quality is a frequent tagline for most everybody in the industry, but I think we're in the unique position of being able to bring the science to reality and contrast the depressingly low quality of construction typically provided.

I'm currently working on continuous insulation wall details for a residential design and would prefer to keep the exterior sheathing against the studs for lateral structural design needs. Does anyone have experience with locating the CI on the interior side of the wall - between the studs and gypsum wall board?
