The act2 demonstration activities in Nantes are focused on the Ile de Nantes district, an area of 340 ha. A total floor area of 80,000 m² of new buildings with advanced energy standards (housing + offices) has been and is being constructed. A large number of these buildings is connected to district heating from waste incineration. Specific decentralized renewable energy systems complete the performed measures, like an energy efficient air-to-water heat pump at the “L’Ile Rouge”, a tertiary building of 3,069 m².
Among the building projects there are two large sites: “Tripode” (Picture 1) with 20,000 m² tertiary and 10,860 m² housing projects, connected to the waste-to-energy district heating system, and “Terrain des Gendarmes” - a 16,393 m² housing project, composed of 4 plots connected to the waste-to-energy district heating system and a 77 m² solar installation (covering part of the DHW demand).
Social housing projects like a social residence for young workers (1,810 m²) and “Corto” (2,800 m²) are included in the demonstration activities as well as the “Prairie au Duc” School (3,700 m²). A Wood Center (tertiary building of 1,500 m², Picture 2) has been built and is dedicated to the promotion of wood as construction material and source of energy.
The “Fonderies” Headquarters Building (4,248 m²) and the large-scale PV installation (182 kWpeak) at “Beaulieu” Shopping Center are explained in the “More Detailed” section.
