Municipality · Insulation of the domestic hot water network

The result

The site has 3 operations: the CO₂ avoided, the CEE volume and the project duration are for the whole site.

Works funded by energy savings certificates (CEE) *

* Insulation of the domestic hot water network: CEE sheet BAT-TH-146, withdrawn on 1 August 2025 (order of 27 June 2025). This work can no longer be funded through a standardised CEE sheet.

How we calculate the CO₂ avoided : The CO₂ avoided is estimated from each project's volume of energy savings certificates (CEE), expressed in kWh cumac, that is, cumulated over the conventional lifetime of the works and discounted at 4% per year. This volume is converted into the energy saved in one year, then multiplied by the emission factor of the energy replaced: 0.065 kg CO₂/kWh for electricity used for domestic hot water, 0.227 kg CO₂/kWh for natural gas (regulatory values from the French order of 31 March 2021). Comparisons: average carbon footprint of a French person, 8.2 t CO₂e per year (SDES, 2024); petrol or diesel car, 142 g CO₂e per km, manufacturing included (ADEME, Impact CO2, 2025).
