Title: Passive earth house
Germany’s field-tested passive house now has an improved successor. It costs no more than conventional building, is easier to build, and functions without backup heating such as heat pumps and pellet furnaces. The Passive Earth House, a hybrid of earth house and passive house, contributes to climate protection due to its low energy requirements (11kWh/m²a) and extreme longevity. Additional benefits are comfortably cool temperatures in the summer and high noise insulation.
