Heating by gas is soon a concept of the past in France, as new regulation is introduced with strict requirements on energy consumption and carbon emissions • A new eco-district in Issy, called Issy Coeur de Ville, will be heated and cooled by geothermal energy and ice storage • Bordeaux builds a new heating network with 80% renewable and local energies • Read more about sustainable heating and cooling developments in France in the November news update
The new environmental regulation RE2020 will soon make it impossible for new buildings to be heated by gas. The regulation specifies energy consumption and CO2 emission thresholds for new buildings – so low that it will be almost impossible to install a gas boiler in a house. For individual housing, the regulation will come into effect in summer 2021, while for multifamily housing in 2024. The new regulation will be a big change for a country where 45% of dwellings are currently heated by gas.
The new eco-district in Issy, called Issy Coeur de Ville, will be heated and cooled by geothermal energy. A 35 m deep whole was recently drilled to start the construction of the geothermal water loop that together with heat pumps and an ice storage solution will provide heating and cooling for the new district. The fully pedestrian area is planned to accommodate 627 dwellings and 40,000 m2 of offices.
A new network will be built in Mérignac, part of Bordeaux Métropole, with more than 80% of heat generated by biomass. The wood used in the boiler will be locally sourced which ensures the project’s ecological nature, in line with France’s ongoing ecological transition. The network will be over 3 km long and distribute 20,000 MW at its full completion in 2029.
Sweden is at the forefront of decentralised heat networks technology. Our aim for “Sustainable Heating & Cooling by Sweden” is to facilitate knowledge sharing between British, French and Swedish stakeholders and develop and encourage environmental and economic best practice.
