TOWERN3000 is an Austrian innovation company pioneering energy-active façade systems that transform the way buildings generate, store, and use energy. Their flagship solution, CEPA®, integrates insulation, heating, cooling, and energy storage into one intelligent building envelope — setting new standards for efficiency and comfort.
Bringing CEPA® to DigiFab
Within DigiFab, TOWERN3000 is advancing CEPA® into a prefabricated all-in-one façade system designed for the fast, low-impact renovation of multi-storey buildings. Working closely with AEE INTEC and Haas Fertigbau, the team is optimizing the façade’s energy performance and simplifying on-site installation, making it suitable even for occupied buildings.
The upgraded CEPA® concept embraces circularity: bio-based materials, reduced resource input, and a design-for-disassembly approach ensure sustainability throughout the system’s lifecycle. Supported by advanced digital planning tools, the solution enables precise system sizing and scalable integration across a wide variety of building types.
Where innovation meets prefabrication
DigiFab creates a unique space where industrial prefabrication and energy-active technologies converge. For TOWERN3000, this means adapting CEPA® for digitalized, fast-track renovation workflows while maintaining cost efficiency, comfort, and adaptability to different building typologies. The result is a façade that doesn’t just protect — it performs, helping to shape the future of sustainable renovation.
Impact in Austria
In Austria, a large portion of post-war buildings are in need of deep renovation. TOWERN3000’s work within DigiFab offers a scalable, low-disruption pathway to transform these outdated structures into nearly-zero energy buildings — without requiring occupants to move out. By demonstrating that heating and cooling can be effectively delivered through the façade itself, CEPA® reduces the need for invasive HVAC retrofits and paves the way for faster, more sustainable renovation practices across Europe.
