Our Challenge

The construction sector is responsible for over a third of global greenhouse gas emissions, accounts for half of the world's resource extraction, and demolition routinely creates significant amounts of waste. Reducing the construction sector's environmental impact through decarbonisation and reinvention is essential for meeting climate goals. This challenge invites you to engage with the future of sustainable building. You’ll begin with online sessions covering the fundamentals of bioclimatic design, eco-materials, and energy efficiency. Drawing on these concepts, you’ll then apply your knowledge to a real eco-construction project in the Rennes area, working on-site at the end of August. Throughout the challenge, you’ll explore examples of innovative projects from around Brittany, where local authorities are supporting sustainable building as part of the region’s ecological transition. This is an opportunity to develop practical and interdisciplinary skills, while contributing to real solutions in sustainable construction. You’ll gain experience in both design and implementation—key steps in turning theory into meaningful environmental action.
