ENGIE Solutions x Rennes
Transform the Rennes Palais du Commerce into a flagship town-centre location
Zero-carbon environmental performance and enhanced appeal for the site
By leveraging environmental performance, energy innovations, sustainable mobility and new digital solutions, ENGIE Solutions will turn the Palais du commerce into an exemplary resilient building. In particular, the renovation project will seek low-carbon building certifications for the renovated sections and the aim is to make the planned wood and glass extension “positive energy”, halving current energy consumption.
The new Palais du Commerce will also be able to produce its own energy locally: photovoltaic panels will be fitted on the roof to generate solar energy, and water from the river Vilaine will be used to cool and heat the building. Harnessing the principles of the circular economy, biosourced local materials will be used for construction, as well as recycled materials recovered from demolition sites. All the spaces will be designed such that priority is given to natural light. Vegetation will be used in the indoor spaces, making for innovative public areas and shops, as well as nearly 2000 m² of co-working office space. A collection of innovations that will give the Palais du Commerce back its status as a must-visit location in the Rennes metropolis.
