Project summary
The refurbishment of the 92 dwellings was part of „50 solar energy housing estates in NRW“. Köln-Bocklemünd was turned into one of the first energy efficient housing estates in the framework of the programme subsidised by the state of North Rhine-Westphalia. Due to implemented measures like additional insulation the heating demand could have been reduced more than 50 percent. Additionally a solar thermal system placed on the roof of the building supplies 30 % of the demand for domestic hot water. Further power is generated by a PV system (9,3 kWp) with coloured solar cells integrated into the facade.

Best practice project
In 2002 Cologne-Bocklemünd has been awarded with the „Sternstadtpreis“ due to its photovoltaics integrated into the facades.
