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.

Energy consumption

• Primary energy need : 35,10 kWhep/m².an
• Primary energy need for standard building : 95,00 kWhep/m².an

Calculation method : RGD du 30 novembre 2007 - bâtiment d'habitation

CEEB : 0.0001

• Final Energy : 32,91 kWhef/m².an
Breakdown for energy consumption :

heating: 4.14kwh/m2/year
domestic hot water: 4.71kwh/m2/year
secondary heating and ventilation + cooling: 4.96kwh/m2/year
lighting and domestic appliances + office for freelance professional: 19.1kwh/m2/year

More information :

the house is fitted with solar panels which meet all of the annual electricity requirements.
In addition, the panels meet the requirements of an electric car which travels +/25,000km/year.

Envelope performance
