Elithis Danube Tower - Catella Case Study

The Elithis Danube Tower in Strasbourg is the world’s first energy-positive residential building, generating more energy than it consumes through solar panels and smart design. Completed in 2018, this 17-story, 63-apartment tower emphasizes sustainability, affordability, and comfort, offering near-zero energy bills and reduced CO₂ emissions. Residents use a Smart Home App to monitor and optimize energy usage. The project demonstrates that sustainable construction can be cost-effective and scalable, inspiring plans for 100 similar towers by 2030.
