Showcase E4S

E4S, Lausanne, 2025

Showcase is the impact innovation summit held each year by E4S (Enterprise for Society Center) at the SwissTech Convention Center in Lausanne. It brings together academia, businesses, startups and civil society around concrete solutions for a sustainable economy. I designed the scenography for two consecutive editions, in 2024 and 2025.

In October 2024, the brief was to create an original, eco-responsible scenography true to the principles of the circular economy: buying fewer new resources, reusing existing materials and extending their life cycle.

My answer started from roll-up banners that E4S had already used. I turned them into a system of colourful modular curtains. Their colours carried through to the signage and guided visitors through the exhibition of 25 circular economy projects.

In September 2025, the summit welcomed more than 1,100 participants in the same space. Together with EPFL, I reused its road signs. A sticker bearing each exhibitor's name turned them into exhibition signage.

For the plenary stage, I again drew on EPFL's stock. Reused triangles punctuate the stage, alongside the SwissTech Convention Center's armchairs.

The Showcase Curtain was born from the 2024 edition. Its modules, cut from the roll-up banners, combine to play with colours and sizes. It can divide a space, dress a window or act as a fly screen. The whole series is now sold out.
