Sustainable engineering: Pavillon Géogami 2, workshops and conferences at Cité des Sciences
From November 18 to 23 inclusive, the School is offering a program of scientific outreach activities focusing on innovation, eco-design, and the reuse of materials. It has been designed for the whole family and schoolchildren at the Cité des Sciences et de l'Industrie, to coincide with Industry Week.

The Geogami Pavilion 2: from mathematics to a structure made from recycled skis and straw
During this special week, students from the Civil Engineering and Construction Department of the École nationale des ponts et chaussées, in collaboration with researchers from the Navier Laboratory, will build an amazing pavilion live, with the aim of promoting innovation, collaboration, environmental awareness, and learning by doing.
This Geogami pavilion is the result of a collaborative research project carried out during Nicolas Montagne's thesis (2021). This work led to the development of new calculation methods to explore innovative design methods, without twisting the skis, ensuring the flat overlap of intersecting curves and allowing for seamless coverage.
Geogami 2 is a new version designed specifically for the Cité des Sciences et de l'Industrie. It illustrates how advanced knowledge of geometry and structural engineering can be used to simply design and build efficient and economical structures from reused elements (skis) and innovative bio-based products (pressed straw panels).
It demonstrates an innovative approach to the circular economy in response to the current challenges of ecological transition.
A variety of workshops and demonstrations will be offered throughout the week until Sunday.
