  • A 54-unit residence will soon be heated thanks to the metro in Rennes.

  • The heat will be captured in the walls of the station using a geothermal process.

  • Another building under construction located on Place Saint-Germain will also benefit from this innovative heating system.

The two brand new buildings stand out in the Cleunay district of Rennes where the housing stock is a little aging.

Located just above the future metro line B station, they form the Emblem residence, built by the landlord Néotoa and made up of 54 housing units and three commercial units.

The owner-occupants have already been installed since the end of the year and the tenants will follow in the coming weeks.

All will live in apartments which will have the particularity of being heated by the metro.

This is not quite a first in France because the heat from the line 11 tunnel in Paris is already used to heat a building of 20 apartments in the 4th arrondissement.

The geothermal process used in Rennes is however a little different since the heat is this time recovered in the walls of the underground station.

"We therefore do not need the metro to be in service for this to work," underlines Philippe Scouarnec, deputy director of Néotoa.

Another building heated by the Place Saint-Germain metro

It is the Rennes metropolis that is at the origin of this energy system, which makes it possible to take advantage of the heat from the basement to heat at lower costs.

During the construction of the second line, which should be commissioned before the summer, it thus participated in the financing of infrastructures making it possible to capture the calories present in the walls of certain stations to convert them into heat.

“This energy is free and the metropolis provides it to us free of charge,” says Philippe Scouarnec, specifying that it is the owners and tenants who will benefit from it.

So that they do not find themselves without hot water or heating in the event of a breakdown, Néotoa has nevertheless equipped the residence with a boiler which will act as a relay according to the consumption of households and the heat released by the metro.

In a few weeks, residents of the Le Persan building, currently under construction on Place Saint-Germain, will also benefit from this innovative heating system.
