Even in a change-oriented construction practice, traditional building solutions are often the go-to choice. This is particularly evident in the selection of ventilation systems. Traditional ventilation systems were not designed with a circular economy in mind, and as a result, they have limited compatibility with adaptable contexts. The ductwork of these systems can pose obstacles to the application of modular wall systems and may introduce acoustic and fire safety challenges.

Circul'Air is a pilot project that explores and demonstrates alternative ventilation concepts better suited for a circular economy. Using simulations and prototypes, the project seeks to develop solutions that enhance compatibility between innovative ventilation concepts and systems designed for flexible space allocation.

Circul'Air documents innovative ventilation concepts conducts a cost-benefit analysis, and expands existing 'general' design guidelines and 'flexible construction' data sheets with specific design guidelines for adaptable ventilation. By implementing in-situ prototypes of innovative ventilation concepts as demonstration projects, Circul'Air aims to raise awareness in the (re)construction sector that ventilation can be approached differently and made adaptable.
