On September 30, 2025, the Housing Agency of Catalonia, LEITAT Technological Center and ITeC have organized, within the framework of the European projects SIRCULAR and INBUILT, the workshop Concrete solutions to the challenges of decarbonization of buildings in the construction sector.

SIRCULAR and INBUILT aim to promote decarbonization and the circular economy within the construction, rehabilitation and building management sector. Their main activity focuses on identifying good practices and testing and applying innovative technologies and services for circular rehabilitation through pilot buildings.

From here, the session will revolve around existing digital and technological solutions for the decarbonization of buildings; in addition to identifying outstanding challenges.

Date: September 30, 2025

Time: from 9:15 to 15:30

Place: ITeC assembly hall (Carrer Wellington, 19, 08018 Barcelona)
