Situated on the banks of the River Rhine, Cologne is the fourth largest city in Germany and home to key players in business and industry. The city is committed to the EU’s goal of achieving a 20 % reduction in greenhouse gas emissions, a 20 % increase in the share of renewable energy and a 20 % increase in energy efficiency by 2020 based on 1990 levels. It aims to reduce CO2 even further, with a 50 % reduction by 2030.

In order to achieve these goals, Cologne is looking to work closely with local industry. Areas of focus include sustainable mobility, energy efficiency of buildings, low-emission heating facilities and ensuring an integrated infrastructure as the city expands.

In this context within the GrowSmarter project, Cologne demonstrates 12 smart solutions in the fields of low-energy districts, integrated infrastructure and sustainable urban mobility in Mülheim, a vibrant area in the north-east of Cologne, which is currently undergoing a process of regeneration.

* Detailed information regarding the technical and financial performance will be available at a later stage.

The demonstration site in Cologne consists of two existing buildings with an overall gross floor area of 33 290 m². The final energy demand of the site has been reduced by 4 990 MWh every year thanks to the refurbishment.

According to SCIS calculations based on energy design data and the respective emission factors available (European factors – EN 15603), the primary energy savings go up to 6 203 MWh/yr while the CO2 emissions reduction amounts to 1844 tonnes every year.
