Full Answer

HOUS.E+ is a self-sufficient home designed to use geothermal energy. It features thick, earthen walls that control the temperature in the home, while energy is created with small water turbines installed inside the walls. The house is also partially underground, which allows occupants to rely on geothermal energy to maintain a constant temperature inside. The turbines operate using gravity and create enough energy for the home in addition to excess energy that is returned to the main power grid in the region.

The Cropthorne Autonomous House is also self-sufficient. The home utilizes a dry composting toilet, eliminating the need for a sewage connection, and relies on triple-glazed windows strategically placed to gather the maximum amount of sunlight for lighting and heat. Rainwater collection systems provide the home with water, and the grey water is allowed to filter through the soil rather than a traditional sewage system. The home is connected to the main power grid in the region, but it also uses solar panels for a portion of the energy used in the home. Occupants of the Cropthorne Autonomous House use eco-friendly soaps and detergents to prevent soil contamination caused by the grey water.
