I would be interested in what you mean by hemispherical and the internal air currents. As far as I know the cheapest way to build is a two story home. It cost around 60% of the cost to build as a one story home of the same square feet. For the most part my comment was that its more effective to build thicker walls and even out your insulation around the entire envelope not pile it in certain areas. It begins to be like comparing 40mpg vs 60mpg vs 18mpg and 38mpg etc...
