In the capital of France, the new Clichy-Batignolles development demonstrates how a city can have a carbon-neutral footprint while providing modern living. The development itself is built on old industrial lands and includes community housing, a theatre, and many other important features of a city including a massive park. The neighbourhood focusses on sustainable buildings and sustainable transit; the developer specifically designed the spaces to be walkable and ensuring that there is no need for a car.
All buildings are being constructed to the demanding Passivhaus standard, meaning that the energy consumption required for heating is just 15 kilowatt-hours a square metre of floor space per year, and the overall energy consumption is under 50kWh asqm of floor space per year.
The buildings are south-facing and super insulated, capturing and retaining the sunâ€™s heat and warmth given off by their occupants and technology. Buildings are composed of renewable materials while other materials such as PVC are banned.
The area will contain 40,000 sq m of solar photovoltaic roofs that will eventually generate around 4500-megawatt-hours a year to supply 85 per cent of the remaining energy needs, while deep geothermal energy will provide 83 per cent of the space heating and domestic hot water, so that the entire site will have a carbon neutral footprint.
