Zero Energy House

With energy costs rising steadily and shortages of fossil fuels a distinct possibility this winter, homebuilders and architects will want to take a close look at architect Zoka Zola's Zero Energy House in Chicago. The term "zero energy" is a bit of a misnomer, as the house does have electricity, though it's produced entirely from the house's own solar cells and windpower.

The house is positioned to take maximum advantage of the sun for both heating and light. Plants and trees (including a "green" roof) provide both cooling and insulation. Ample windows provide ventilation to cool the house in the summer. In the winter, concrete interior walls can retain heat to keep the house warm throughout the night.
