You strip the house of all exterior siding, then build out frame work to allow about 10-12 inches of high density insulation. On new construction you can aim for 2 feet of insulation. The house is then sealed for air loss. Generally you need an air to air heat exchanger for fresh air exchange.
The idea came about with solar house heating. If you minimize the heat loss, you can minimize the heating. In college, we modeled many solar house designs but found that super-insulating was the most cost effective, even without the solar heating!
