La Fleuriaye (Nantes, France)    

  • slider

La Fleuriaye is a sustainable eco-district located in Carquefou, in the metro area of Nantes, France. Planning for the eco-community began in the late 90’s and has since resulted in the largest Passivhaus community in France, with over 300 Passivhaus certified buildings being completed in Summer of 2016. The Passivhaus rating results in a very low energy demand, meaning less or equal to 120 kWh of primary energy per m² per year. The community has been able to generate 80% of the district’s electrical demands and provides real time energy monitoring via a district wide integrated smart grid.

The real time energy management of the district, combined with the Passivehaus rating of the buildings is expected to provide 100% of the primary energy demand as described by the La Masion Passive, France’s Passivhaus certification system, “By mid-2017, it is 6000 m² of photovoltaic panels that will be installed, with the goal of reaching a 100% coverage of total primary energy consumption for all uses of buildings.” The project expects another 300 buildings to be completed by mid-2017, all meeting similar energy consumption numbers. The further expansion, totaling over 600 Passivhaus buildings will make the eco-district the largest Passivhaus development in Europe.
