Chaleureusement vôtre

Teams of VoisinMalin, who came to the Campus, have heard of Operation Chalheureuse experienced on site (method participative organization of thermal comfort to limit energy consumption without degrade the comfort of life, through simple and fair means). They did it connection with a big issue of summer and winter comfort in Some priority quarters. Thus the idea was born to extend together this Operation Chalheureuse beyond the Campus.

January 2026 : The beginnings

Following their meeting, Campus and VoisinMalin partnered to bring together to the Foundation of Urban Solidarity on project « Warmly Vôtres : Acting Together against Precarity Energy", a research-action approach with local Priority neighbourhoods of the City, the QPV. In these neighborhoods, the effects of climate change and energy insecurity combine - old collective housing, overheats in summer, cold persistent in the winter, collective heating little controllable.

To Évry-Courcouronnes (historic settlement town of VoisinMalin) and Montereau, more than 70% of the inhabitants say they are too hot in summer 62% too cold in winter, well above average National.

The Malin Neighbours, trained in listening and local mobilization, will be at the heart of the co-construction process, Valuing knowledge of use, experience and local skills. The approach aims to strengthen household power and document social benefits of energy sobriety, while creating a space for dialogue with donors. The project, winner of €80k of the foundation of urban solidarity and 15k€ of the endowment fund Qualitel, will go up for two and a half years. It started at the end of January by a respective immersion phase: each party will discover the the other's lifestyles (at the Transition Campus and in the QPV of the project - Évry-Courcouronnes and the Surville district in Montereau-• He continue with a 1-year experiment with the Malinian Neighbours and will be followed by a dissemination of the teachings to locals.

The project will be evaluated in particular by Hélène L'huillier and Cécile Renouard, thanks to indicators for measuring capacity and living well. Most curious will be able to dive into "The People of the Frillies",Olivier Jandot andRenan Viguie, historians working on thermal comfort and in which Operation Siberia (previous name given to Operation Chalheureuse at Campus) is very quickly mentioned. Funny and rewarding !

Spring 2026 : First experiments

The Campus team went to Evry at the end of March for a first meeting with the Malian Neighbours team involved in the project. Exchanges have turned around the perception of the issues of summer and winter comfort and the question of energy cost. The Neighbours were also very interested in environmental issues.

On May 13, the Campus team returned to Evry, this time for a Immersion of a day. The aim was to understand the specific context of the two neighbourhoods and of their inhabitants: the Canal and The Pyramids district. They are both classified as priority areas of the city. They do the subject of a major programme urban renewal for the past ten years and the association VoisinMalin y has been operating since 2010. Each visit, in the two neighborhoods with very different shapes, has was organized with a Neighborhood Maline living in the neighborhood and the Knowing like his pocket. The neighbourhood the Canal is mainly composed of small buildings of 3 floors, when the Pyramids consists of large buildings in the shape of... pyramids. Of the 9 Neighbours who will be involved in the project, 5 live in the Canal area and the Pyramids area.

Team also exchanged with an employee the Local Energy and Climate Agency of South Paris (ALEC). This agency was formed on the "SlowHeat" approach, a few weeks ago, which is very close to what was experienced at the Campus via Operation It's warm.Partnerships could emerge from these exchanges... The day ended with participation in a door-to-door duo or trio session with a Neighborhood with a campaign on a whole other subject. This practice is at the heart of the actions of the Association Voisin Malins and the Campus team is very happy to have been able to participate to better understand part of the work of the Neighbors.

Finally, on the weekend of 23 and 24 May, the Voisin Malin team came to immerse themselves at the Campus! On the programme: visit of the places, exchange on the elements of thermal comfort, sharing on ways to fight against the weather and cold at different times and geographical locations, not to mention user-friendly and inter-knowledge.

The weekend was very rich, both for the Campus team and for the VoisinMalin team.

Some sharing of the closing time:

"To link the environment with thermal comfort is a citizen's commitment; It's carrying a message for our planet."

"I thought it was great what happened this weekend, it gives me a lot of hope and confidence for the continuation of the project."
