For even a greater savings, a new house can be built with extra thick super insulated walls, air-to-air heat exchangers to warm incoming air, and even double-walled sections that create a "house with in a house." The R-2000 program of Canada details how energy conservation can be built into homes. Special double-glazed windows that have internal reflective coatings and that are filled with an inert gas have an insulation factor of R11. Super insulated houses now being built in Sweden require 90 percent less energy for heating and cooling than the average American home.
Orienting homes so that living spaces have passive solar gain in the winter and are shared by trees or roof overhang in the summer also helps conserve energy. Earth-sheltered homes built into the south-facing side of a slope or protected on three sides by a earth berm are exceptionally efficient energy savers because they maintain relatively constant subsurface temperatures. In addition to building more energy-efficient homes, there are many personal actions we can take to conserve energy. The secret to building your own Wind Power Generator is just a Click Here away.
