Let’s get things rolling!

On April 5, about 40 people gathered to green the wooden structure at Place des Saugettes by planting hops, clematis, and other climbing plants. It was an opportunity for participants to learn more about summer heat and to explore the structure.

During the summer of 2025, various measurements were taken to determine, for example, surface temperatures and perceived temperatures at different locations on the square, both with and without the new cooling features.

A study of how the square is used was conducted by a specialized consulting firm. A questionnaire was also distributed to the public to assess whether the revitalization brought about by the structure makes the square more attractive.

An exhibition to present the results

See the results of these temperature measurements, usage observations, and the survey in the form of an exhibition at Place des Saugettes. The exhibition will be on display until fall 2026.

What is this structure?

An innovative structure has been installed at Place des Saugettes, in collaboration with EPFL. The goal is to make the square cooler and more welcoming through the use of greenery.

This structure consists of planters filled with soil and bamboo arches that guide the climbing plants.

Find more information about the structure on the BamX page.

What’s next?

The structure will remain in place until work begins on this square. This structure is a pilot project for temporary green space development. The key lessons learned will help continue the work already underway to adapt the city to climate change.

This initiative is part of the Lausanne Climate Plan, whose commitments are:

• Achieve zero direct greenhouse gas emissions by 2050

• Adapt the city to cope with climate change

• Raise public awareness and encourage people to take action
