On April 24, 2026, the IGCE participated in the Long Night of Research, welcoming visitors of all ages to explore the world of resource-efficient construction through interactive exhibits and hands-on activities.

Throughout the evening, participants had the opportunity to learn about sustainable building materials, resource-conscious design strategies, and the environmental impacts of different construction systems. A particular focus was placed on understanding the carbon footprint of building materials and exploring how engineering decisions influence the sustainability of the built environment.

One of the most popular attractions was the Leonardo da Vinci bridge challenge. Visitors were invited to construct the famous self-supporting bridge using only wooden elements—without nails, screws, or any other fasteners. The activity provided a practical demonstration of structural principles while highlighting the ingenuity of efficient design.

The challenge inspired participants of all ages, with one visitor completing the entire bridge assembly in an impressive 1 minute and 38 seconds. The bridge also successfully passed an unconventional load test involving a four-legged visitor, proving its remarkable stability.

The event offered an excellent opportunity to engage with the public, discuss current research activities, and demonstrate how engineering can contribute to a more sustainable future.

The IGCE team would like to thank everyone who visited our station, participated in the activities, and contributed to the lively discussions throughout the evening. We are particularly grateful to Marc, Jakob, Roman, Johannes, and Sara for their commitment and enthusiasm in making resource-efficient construction accessible and engaging for visitors of all ages.
