Ductwork Systems for Efficient Building-Integrated Technologies
Westaflex, an AEGIR project partner, is developing innovative ductwork systems to support deep building renovation. Upcoming demonstrations will explore the integration of this ductwork into efficient building renovation solutions at AEGIR demonstration sites.
How do ductwork systems contribute to more efficient energy performance in buildings?
Indoor air quality depends on the supply of fresh air and the removal of contaminated air. However, when contaminated extract air is discharged directly into the environment, the heat it contains is lost without being utilised. By enabling heat recovery from extract air, ductwork systems help retain and reuse this energy, improving overall energy efficiency and contributing to a more energy-efficient building.
Thanks to the support of the AEGIR project, Westaflex will deploy innovative ductwork integration at three demonstration sites in 2026, at:
Boën-sur-Lignon, France – for residential ventilation
Oradea, Romania – for residential ventilation
Denmark – for non-residential ventilation
Ductwork Innovations
Westaflex is developing new ventilation components for prefabricated façades. These innovations cover not only the components themselves, but also the working methodology in relation to other building disciplines. Key areas of innovation include:
- Integration of air ducts into prefabricated façades
- Combination of façade system elements
- Combination of centralised and decentralised ventilation
- Route planning for air ducts within buildings
- Coordination across specialist areas
Three European Demonstration Sites for Real-Life Validation
The three demonstration sites will showcase complete building renovations, delivering measurable energy savings, improved user comfort, and reliable system performance under real-life conditions.
Oradea, Romania
The residential building will be fitted with prefabricated façade elements. The air ducts will be routed both inside the building and externally along the existing façade. This duct routing requires close coordination between the various specialists.

Denmark
In this non-residential building, the air ducts will be integrated into the prefabricated façade elements. The main challenge is that the installation of the façade elements must occur simultaneously with the connection of the air ducts between individual façade elements and the wall. This requires the use of entirely new types of ventilation components.
Through the AEGIR project, Westaflex’s innovation helps demonstrate the practical feasibility of integrated ductwork renovation solutions that can be deployed across Europe to meet ambitious climate and energy targets.
