You can use "Comparez vos coûts d'énergie" (in French only) to find out the average energy consumption of a home similar to yours. Several factors are compared.
If your actual energy consumption is lower than average, your home is energy efficient. If it is higher, an energy upgrade may help reduce the energy bills.
Energy-saving strategies are proposed. To find out whether they can be applied to your home, ask for the energy evaluation service.
