Local authorities, public developers and energy syndicates

At the point where a number of traffic flows converge, right at the junction between the town's northern and southern districts, Rennes’ iconic Palais du commerce serves as a type of screen, dividing instead of properly articulating the town's different areas An invitation to tender was issued in March 2018 as part of a project to revitalise this area. It had a number of objectives of an urban, architectural, commercial and environmental nature. An exemplary challenge in terms of energy efficiency, environmental performance and sustainable development that ENGIE Solutions took up alongside the Frey consortium, winner of the invitation to tender. Ultimately, it will be an open and appealing town space, serving the inhabitants of Rennes, who will once again have use of the Place de la République and its surrounding areas (which is being developed at the same time).

The Angers Loire Métropole urban community wants to transform itself into a fully-fledged smart region. Managed by ENGIE Solutions and a consortium of partners, the Smart City project seeks to improve the way in which public services are managed and their relationships with residents. It aims to create new ways of doing things, while reducing the environmental footprint and energy spending.

The Rennes metropolis boasts numerous assets, including an airport, a high-speed train station, a metro system and bicycles. The only thing that was missing was a conference centre to enhance its appeal. Wanting a site that was in keeping with the town, the elected representatives naturally turned their attention to the Couvent des Jacobins. Built in the 14th century, this imposing monument has evolved over the years and has served numerous purposes, including accommodation for monks, a base for the army and a venue for biennial contemporary art exhibitions. It is the ideal setting to help increase the region's influence. Turning it into the town's conference centre had to be done, and doing so was a technical challenge in terms of providing all the services and levels of safety that such a building needs to have for its visitors.

Porte de Montreuil on the eastern outskirts of Paris is currently an urban area dominated by road structure that is not very suitable for pedestrians and cyclists. The City of Paris wants to redevelop it into a proper destination area – a place where people can congregate. It wants to recreate bonds between Porte de Montreuil and neighbouring districts, increase the number of different activities going on within it and improve the balance between housing and employment.
The City of Paris also wants to create new momentum for development and innovation that is in line with the ecological transition and which takes up the social, economic and environmental challenges of the region and its residents.

The Greater Reims region and the city of Reims want to develop their environmental performance strategy, their goal being to have 90% of the energy used for their urban heating and cooling networks recovered or generated from renewables by 2022. In addition to encouraging the circular economy, this solution is evidence of ENGIE Solutions' commitment to local employment and improving quality-of-life for residents.

Metz has had a sustainable development policy for more than 10 years and includes reducing greenhouse gas emissions by 40% in the targets it has set itself for 2030. In 2014, the community entered into an eight-year energy efficiency contract with ENGIE Solutions, focusing on its four municipal swimming pools. The aims involve ensuring long service lives for the buildings, reducing the swimming pools' energy bill, ensuring technical compliance, improving the comfort of people using the facility and improving access for people with reduced mobility.
