For improved air quality in urban areas


The air in German cities is often worse than the EU limits allow. Fine dust and nitrogen oxides adversely affect the quality of the air and preventing them is an effective way to combat climate change, Fine-dust pollution plays a major role in the development of cardiovascular and respiratory diseases and increases the overall mortality rate of the general population. We are the market leader for customized real estate concepts and a pioneer in sustainable solutions in the development sector. This is why we are testing the world’s first nitrogen-oxide-binding textile facade on an office building at our ECE campus in the Poppenbüttel district of Hamburg. These textile facades can also be easily installed and subsequently replaced on buildings of all types of use. This means that buildings can be subsequently adapted to changes in the climate.

Reduktion von CO2-Emissionen

Also reduces CO2 emissions

The facade not only binds nitrogen oxide, but also helps reduce CO2 emissions: studies have shown that the innovative building shell can reduce a building’s solar cooling load during the summer by up to 78 percent. How is this achieved? The first contact with energy-intensive solar radiation does not occur on the actual building wall as with conventional buildings, but in the space in front of the building. In addition, a passive cooling effect between the textile and the building shell results due to natural heat dissipation via convection.

Live-Monitoring der Luftqualität

Spectacular real-time monitoring of air quality

A complex measuring system with digital measurement technology on the facade makes it possible to monitor the air quality in real time. A total of 24,000 euros were invested for this purpose. The results of the study will reveal the extent to which the facade plays a role in improving air quality. The system measures the impact on the urban space and the impact on the interior of the building.


“Conducting business activities in a sustainable manner is one of ECE’s central corporate objectives. This also includes being open to new technologies. As such, we’re excited to test Germany’s first nitrogen-oxide-binding textile facade on our corporate campus and to use the pilot project to provide new insights for other locations. This would be a valuable contribution to combating climate change that begins on our own doorstep.”


“We developed the air-purifying textile facade specifically to help protect the environment and people’s health. At the same time, we’re combining energy efficiency with an innovative facade design. We have also decided that we are also going to collect rainwater samples on the facade in order to test and scientifically verify its environmental compatibility.”
