This building was designed to provide private apartments and commercial offices in a solid construction style with controlled heat recovery.
A photovoltaic system is located on the housetop. It provides for an electrical output of 5 kWp. In addition to this a solar thermal system for the hot water supply is mounted on the housetop, too.
The building will be heated by a heat pump; a rainwater utilization system provides the garden and the toilet with water.
