It will be the first circular road in France covered with a shaded house PV. A study has been launched to equip 45 km of the Bordeaux Ring Road with a giant canopy house composed of optical sensors. This project, led by an urban architect from the Paris region, is located on the office of the Ministry of environmental transformationthe mayor of Bordeaux reveals Pierre Hermic (EELV) who was asked a few months ago, who said he defends it enthusiastically.

“I took possession of this project when the city of Bordeaux received an award fromJesty Dore [association représentant les métiers du bâtiment]in the context of the various urban achievements of heating networks, explains Pierre Hormec 20 minutes This Friday. This association then told me about this urban architectural planner who was considering covering the Bordeaux Ring Road. I looked at the project which immediately seemed to me interesting, because I am looking for the smallest spaces to promote Solar energy On our territory, we do not have much in the city. »

Chassis also equipped with CO2 and particle sensors

The project will cover a total area of ​​200 hectares, “and the production will make it possible to supply 40,000 homes if they are fully electric (heating, hot water, etc.) or 80,000 homes if they are semi-electric” defines Pierre Hormeck.

A first study, rather brief, was presented to a mayor Bordeaux. There we can read that this shelter will also be supplemented by sensors of carbon dioxide and particulates, gases that will, in turn, turn into local energy. The chassis will also be equipped with “sound traps” capable of reducing traffic noise by 38 decibels. Finally, the panels will be fitted with rainwater collectors, which will be stored in retention basins for dry periods.

“I would like Bordeaux to be a leading city in terms of solar energy”

I spoke with the Prime Minister about this. John Castex Which I received on the phone at the beginning of April, continues Pierre Hermec. This is a project of the state’s responsibility as it owns the ring road, but I want to support it and believe in its feasibility. “The mayor of Bordeaux hopes that this will be achieved ‘as soon as possible’ even if he thinks it cannot be done all at once. The Ring Road passes through several municipalities, but we can start with those where the mayors are more voluntary, and I am part of them.”

Financially, the project has not been quantified, but it could be carried out by a private partner, such as the Lappard PV plant, which opened Thursday in Bordeaux. Installed in a former landfill, it is currently the largest power plant in an urban environment in Europe. “I would like Bordeaux to be a leading city in terms of solar energy, and after the Labardi power plant, we must continue the projects to move towards energy independence.”

Target: 60,000 m2 of solar surfaces

Especially since space is scarce, and Pierre Hormack is less enthusiastic when it comes to installing power plants in landscaped spaces like the project. Horizio In Saucats south of Bordeaux. “Capitals use a lot of their neighborhood to meet their needs, which he regrets. They must give themselves the means to accommodate infrastructures dedicated to their energy independence within their periphery, and this project is moving in that direction.”

The city of Bordeaux is implementing several other projects of its own. “We are considering all possibilities, and I want that by the end of my term, 60,000 square meters of municipal rooftops will be equipped with solar panels. In particular, there will be a submarine base, schools, etc. All future buildings will be equipped with solar energy, an approach that facilitates the development of materials , I also think especially of solar tiles. But we know that won’t be enough to achieve the carbon neutrality we’ve committed to. The Circular Road in this sense is a “great opportunity” that the Mayor of Bordeaux doesn’t want to miss.
