The high rise apartment block at Bugginger Strasse 50 was the world‘s first high rise with passive house construction certification and requires less than 15 kWh per year for its heating facilities. The renovation of the building produced a 78% saving in energy used for heating – despite the work allowing room for social aspects such as common rooms, guest apartments and even a concierge. The layouts of the individual apartments were improved in order to reflect demographic changes.
To be viewed from the outside, guided tours by appointment.
