Research & development I Circular building

A circular system for large-scale façade renovations 
Building managers with a large patrimony often have residential buildings with similar characteristics. They usually have a long-term vision for the renovation of their patrimony, spread over decades. Acceleration of the renovation rate is required. 


By looking at shared characteristics between buildings on a larger scale, the circularity of a façade renovation system can succeed. This is because in contemporary, building-specific systems, the chance of reuse decreases. 


This research team develops a sustainable modular reusable façade system for renovation. It will allow existing buildings to be quickly renovated in a circular way. Because of these properties, the use is scalable and approximately 80% of these residential buildings can be renovated in the short term. The system takes into account the option of reusing the existing exterior joinery, if relevant.

The research also focuses on the possible integration of techniques such as ventilation and hydraulic circuits into the façade package. This will allow the interior space to be used in a more flexible way and to easily take on other functions in the future.

This future-oriented system will be tested in three cases.

Bureau Bouwtechniek is leading this research project.
