The NEF, a social rehabilitation project with exceptional architectural and energy performance

The Nef project, in Tours, has received the Silver Pyramid award. It was recognised by the French Federation of Property Developers (FPI) for its aesthetic and environmental performance.

  • The entire property, built on the site of a former postal sorting office on Rue Blaise-Pascal, was designed to generate just as much energy as it consumes.
  • The use of geothermal power, the addition of 1500 sqm of photovoltaic panels, and the sharing of technical facilities by residents and staff (only three lifts have been installed) allow the Nef to generate as much, if not more, energy than it consumes.
  • An innovative geothermal system: it heats the housing, while the cold air is stored to cool offices, via radiant ceilings. This principle helps achieve a satisfactory level of comfort without air conditioning.
  • The roof terrace is equipped with 1600 sqm of photovoltaic panels to produce approximately 240,000 kWh/year.
  • The building’s energy performance is monitored using an internet portal allowing each inhabitant to monitor their own energy consumption in real time. The instructions for the building are provided for future residents.
  • Rainwater from the rooftops is recovered for domestic use (supplying toilets and watering the vegetated façade that will cool down the building naturally during the summer).
  • All insulation components and the framework of the homes on the terraces are made of wood, which significantly reduces CO2 emissions.
