100% Passive House, Courcelles-les-Lens, France

Olivier Baey is an ecologist at heart; he currently lives in a house built in the 1950s with single-glazed windows, poor insulation and oil-fired central heating: the typical profile of the high-energy-consuming house. For example, he pays more than €3,000 a year in heating, whereas the budget for a passive house is €300 at most. When a new addition arrived in the family, Olivier Baey decided to build his own 100%-passive house, using the most environmentally friendly products available on the market.
