Eglise Saint-Gervais Cielis

Enhancing Saint-Gervais Church by limiting energy consumption

Energy Division

This project is part of the Cielis contract to renovate street lighting in Paris, thus contributing to the city's climate plan targets. We are managing the contract in consortium with Dalkia Electrotechnics and Citelum.


The aim of Cielis is to renovate over 70,000 light sources in the city while maintaining high service quality and limiting the impact on biodiversity. 

For the Saint-Gervais Church project, our teams climbed up to the church's highest floodlights to replace them with LED technology, more cost-effective in terms of consumption. The result is a remarkable architectural enhancement and significant energy savings. 

This project support our heritage conservation, while at the same time promoting a more environmentally friendly approach
