This modern home built in Wisconsin by designer Shane Black uses solar thermal panels to heat a bed of sand beneath the house, keeping the interior temperature comfortable throughout the year. Combined with smart window placement and energy-efficient building techniques, the project achieves a 50% savings in energy consumption. Black’s goal was to create a home that utilized as many of his ideas as possible while at the same time being earth-friendly, proving that it’s possible to create a unique, beautiful home that also has a low impact on the environment.
