Primary energy need
35.1 kWhep/m2.an
(Calculation method : RGD du 30 novembre 2007 - bâtiment d'habitation )
Construction of a new passive house which uses solar panels to generate all of its own electricity to meet its heating and lighting requirements and which also produces its own water for daily use by collecting rainwater and treating it with UV light. In addition, the house also produces electricity for an electric vehicle which travels +/-25000km a year.
Heating is supplied using a ground-water heat pump and the air is renewed by a dual-flow CMV.

Owner approach of sustainability
As both the client and contractor on this project, we wanted to make a self-sufficient home in terms of energy and water and we opted for a 100% electric car which will be powered by our own electricity generated by the solar panels. All energy-consuming devices have been chosen for their low electricity consumption (e.g. LED lighting).
Architectural description
Massive passive house, using: 1) the ground to power a ground-water heat pump which heats the house, 2) rain to supply all water outlets, 3) the sun to generate the electricity required for heating and for domestic electricity as well as for "fuelling" an electric car which travels +/-25,000km/year.
