Best Way to Insulate a Interior Block House

Insulating an old cinder-block building

Hello! I have a 1975 building that I am renovating. It is primarily a cinder/masonry block building.

The blocks are standard 16″ x 10″. There is no insulation in the cavity (vermiculite) of the blocks.

I am in Penticton, BC Canada which is Climate Zone 5. I wish to properly and price-effectively insulate the walls. Nosotros accept a Building Permit issued for the renovation, which says we accept to conform to 2012 BC Building Code rules. However, afterward much research, if I insulate based on the 2012 code, there stands a high probability that the walls will condense wet and cause rot/mildew/mold.

I need to know the proper way to insulate while notwithstanding adhering to 2012 Code.

I was thinking of the post-obit in the order of assembly:

[Exterior Latex Paint over Cinder Blocks] [Cinder Block] [2″ XPS FOAMULAR R-10 Rigid Insulation glued to Cinder Block] [two×vi framing 24″ O.C.] [R-19 Unfaced Fiberglass Insulation Batts] [Drywall] [Latex Pigment]

There volition be NO vapour barrier to allow the associates to breathe. This is based on Building Sciences article BSD-106: Understanding Vapor Barriers. Delight see fastened wall assembly.

The latex paint will act as a Form III Class III Vapor Retarder.

1) Is this a adept approach?
2) It is not per the 2012 Code, but if I practice not do information technology this way I can potentially create a sick edifice.
3) Is there a better fashion?
4) I do non want to use Airtight-Cell Spray Foam as it is too expensive and toxic.
5) How can I convince the City Inspector that I must build the walls properly even though information technology does not meet 2012 Code?

Help!!!

Thanks in advance!!!
