In the face of the urgency of climate-related issues, reducing CO₂ emissions is a priority. The building sector is a real lever for reducing the carbon footprint and achieving energy savings.

Heat pumps, heat networks and high-performance insulation are all cost-effective[1] and more environmentally-friendly solutions to speed up the development of low-carbon buildings.

Representing 26% of emissions in France[2], building is the 2nd largest CO₂ emitting sector after transport.

Low-carbon construction

RE2020 regulations, real progress in favour of the climate

In order to achieve the carbon neutrality of a building, action is required from its design onwards. The reduction of energy requirements and the use of renewable energies through heat networks, heat pumps and biomass enable a significant reduction in CO2 emissions from buildings.

To support low-carbon construction and the energy performance of buildings, RE2020 environmental regulations will be mandatory as of January 2022 for individual homes, collective housing and most likely for office and educational buildings.

Energy renovation to reduce CO₂ emissions in buildings

Energy renovation is a major driver in the reduction of the carbon footprint of buildings. It enables the reduction of energy bills, the improvement of occupant comfort and the limitation of CO₂ emissions.

Insulation, ventilation and the replacement of heating systems are all solutions to improve the energy and environmental performance of housing and tertiary buildings. Financial aid[3] for works also exists.

The heat pump, a more cost-effective and environmentally-friendly solution, for both new and existing buildings

The heat pump is energy efficient and enables a home to be heated and cooled using renewable resources (air, water, soil). It is a future solution proposed by EDF, replacing fuel oil or gas boilers.

The HP, the solution that emits the least CO2 per KWh*

  • > 300g

    Fuel oil heating

  • 220g

    Gas heating

  • 79g

    Electric heating

  • < 40g

    Heat pump

* Quantity of CO₂ emitted per KWh heat produced per unit

How does it work?

Easy to operate, the HP captures the heat or cold naturally present in air, water or soil to heat or cool your indoor space and produce domestic hot water.

How can I get equipped? How can I finance this?

The heat pump

What are the advantages?

With an average production of 4 kWh of heat for 1 kWh of electricity consumed, the heat pump (HP) enables both the control of energy bills and a significant reduction in CO₂ emissions from buildings.

  • Good idea for the climate : with a heat pump, you can reduce your CO₂ emissions by up to 90% compared to fuel oil and by up to 70% compared to gas[4].
  • Good idea for bills : with a heat pump, save up to €1,000 per year compared to a fuel oil boiler[5].
