Superior Walls precast concrete above grade? – GreenBuildingAdvisor

I am considering using Superior Walls precast concrete walls above grade on my next build.

On my last build, I Superior Walls for a daylight basement.  We added pigment to the mix to give it an earth-tone color and broom finished the exterior; we also applied concrete sealer.  It looked somewhat like a stucco finish. We added extra insulation on the inside, and a little extra insulation on the exterior of the slab / wall base (to provide a thermal break).  This got us to Net Zero Ready certification.

The pros of precast are:  1) one and done walls;  2) excellent air seal; 3) bug proof; 4) reasonable cost, if you account for exterior finishes and  insulate / finish the interior.  The cons are:  1) You had better not make a mistake when you are ordering the pieces!;  2) exterior faces can get dinged during installation; 3)  awkward for wiring;  4) the joints between the wall sections are notice-able.

Overall, I liked the system, and am considering it for use above grade in zone 4 (MD).  Has anyone else seen, tried, or considered Superior Walls above grade?  All comments are welcome.
