During the CTB online partner meetings, each partner is given the opportunity to present a more detailed view of their regional characteristics, challenges and approach to circularity. On 19th March it was time to our French partners from ENSAPL to take to the digital stage.

Leading sustainable architecture & circularity
Vincent Ducatez introduced the CTB partners to ENSAPL. As one of France’s top architecture schools, the École Nationale Supérieure d'Architecture et de Paysage de Lille (ENSAPL) is taking bold steps to shape the future of sustainable and circular architecture.
Located in the heart of Lille, a city with a rich industrial history, ENSAPL is committed to fostering innovation and addressing the pressing environmental challenges of our time.

Historical & Geographical Context
Lille and its surrounding region, once dominated by coal mining and the textile industry, face significant economic disparities. The decline of these industries in the 1970s left areas like Roubaix grappling with poverty, while the vibrant city center of Lille stands in stark contrast. This juxtaposition of wealth and poverty is mirrored in the city's architectural landscape, which blends historic buildings with modern design.
With its roots going back to 1671, ENSAPL has a legacy ofexcellence and long been a leader in architecture education in France. Today, it is one of the country’s top five architecture schools, offering bachelor’s, master’s, and Ph.D. programs to over 600 students. At ENSAPL, education goes beyond traditional architecture – it’s about preparing future architects to tackle the most critical issues facing the built environment today.

Circularity & Sustainability is core
ENSAPL has made sustainability and circular design a core focus. The school is committed to reducing the carbon footprint of buildings, moving towards carbon-neutral construction by showcasing recycled and biobased materials, including straw and timber. Students participate in hands-on workshops and field trips, gaining experience in designing buildings that are both reusable and disassemblable.
The school is also at the forefront of research into how architecture can help fight climate change. In 2019, the ENSAPL team was recognized for its efforts in carbon-neutral design by winning the prestigious international university competition Solar Decathlon Europe. The research includes developing tools to help architects calculate the carbon footprints of buildings and incorporate sustainable practices into their designs. Collaboration with international universities and projects ensures ENSAPL students are exposed to global sustainability practices.

Activities within CTB
ENSAPL’s future initiatives within the CTB project aim to build on these efforts. The school is launching new training modules, focused on circular design principles and carbon reduction. One exciting new initiative is the 0CO2 Club, a platform where architects, students, and professionals can share ideas and best practices for achieving carbon-neutral buildings.
Additionally, ENSAPL is preparing to launch an international summer school and strengthen ties with the University of Lille, creating opportunities for deeper interdisciplinary collaboration.
The shift towards a circular economy in architecture is radically transforming the way buildings are designed and built. With France’s goal of reducing the carbon footprint of buildings by 30% by 2030, the focus on sustainable, carbon-neutral architecture is more important than ever. ENSAPL is playing a crucial role in driving this change, preparing the next generation of architects to tackle these challenges head-on.
