Another way (the best way, imho) is to apply synthetic stucco over styrofoam
insulation. I doubt that heat or cooling costs are gonna drop, every little
bit of insulation is needed to cut alkaydas grip on the world.

But check with your insurance agent first -- syntehtic stucco over
foam is almost uninsurable in many markets because of all the water
intrusion, rot, and mold claims that are allegedly caused by dfective
matierals, sloppy installation, or improper maintenance, depending on
whose lawyers you ask.
