Maybe not air. What I mean to say is that it’s full of hot gas. See the quote referrenced below the link. Instead of truly degrading the energy use in the house they simply offload it onto a natural gas line instead of the grid or local power generation and presto, you don’t need as much electricity.
Lemme give you a clue. I can run a gas generator to power my home and use no power off the grid. Somehow, I don’t think that’s the idea of an “efficient design.
Although the do do some things “right”. But the first thing I did when I moved in at my house was rip everything out, put in all fluorescent lighting, and install efficient ceiling fans instead of a cooling system. They also help with heating.
Unfortunately, photovoltaic cells (Solar Power) isn’t an option here in the North East, with our 40 sunny days or so a year. Maybe I’ll move to the ocean and create a decent tidal generator.

The kitchen uses LP gas to power the refrigerator and stove. The stove also integrates a toaster into its design. There is no dishwasher, and the other kitchen appliances are manual. In the laundry, there’s an efficient 12V washing machine, and a gas powered dryer. Clothes are dried on racks where possible. The house uses solar thermal panels to heat water, supplemented by LP gas.
