Renewable energies (RES) are growing in the housing sector. In fact, in order to contribute to the reduction by 6 of CO2 emissions per m2 required to reach the "factor 4" by 2050, they are gradually introduced as references in successive thermal regulations (2005 then 2012).
In 2009, heating using renewable energies (geothermal, photovoltaic, heat pump, wood) was chosen by 41% of individuals who had a house built. The use of renewable energy for heating increased by 50% between 2006 and 2009 in new individual housing.
The factor that has the most influence on the choice of renewable energy heating is the type of professional who coordinates the construction of the house. The proportion of houses heated in renewable energies is lower when they are built by a builder than when the individual uses another type of professional (architect, entrepreneur, craftsmen).
Access to heating by renewable energy is conditioned by the financial means of the building household. It is in fact associated with houses of large surface area, on large land areas and at relatively high prices. It is more common among farmer farmers (57% in 2009) and among senior managers and intellectual professions (48%).
