In the façade sector, the ecological and circular transition requires the adoption of new business models that exploit the value of the material as much as possible. In this context, the Internet of Things (IoT) is identified as a potential innovation driver for the widespread use of circular approaches. The aim of the paper is to clarify the role of IoT in enabling five circular business models in the façade sector. The potential benefits of an IoT-based façade system are highlighted through a matrix underscoring the relationship between information produced and key actions to achieve the innovative business models. The research discussion and findings open the debate on the perspective of digitally integrated building components.
