In Köln-Mülheim a building complex from the year 1959 was redeveloped to a solar energy housing estate. The 5 multiple dwellings with 44 units were provided with a good insulation and a solar plant for water heating. The CO2-emissions, which are produced by heating and water heating, could be reduced thereby more than 2/3.

Features of the development

• 44 residential units
• approx. 55 % of hot water supplied by solar thermal plant
• Reduction of CO₂-emissions from 62 to 20 t/a
