“passive housing”, virtuous insulation without heating

Living without heating, even in an old building, is possible. This Parisian apartment, located on the top floor, is passive housing. “Triple glazing allows you to capture more energy than you lose.”, explains Victor Hoppe. The sunshine and the heat generated inside the apartment are sufficient to meet the heating needs, according to this engineer. There is only an auxiliary heater for very cold weather.

3,500 buildings considered passive housing

Cost for this 25 m2 apartment, about 7,000 euros for work: triple and quadruple glazing for the windows, insulating panels on the walls, and a double flow insulation system. This virtuous insulation increasingly concerns old buildings, and not just new homes. In the Paris region, a construction site is underway at the heart of a house from the 1960s. The building was considered a thermal sieve. It will soon have an energy diagnosis classified A. In France, around 3,500 buildings are now considered passive housing in France.
