- By closing the blinds or the shutters during the night, you create an additional insulation

- Look after the insulation of your house, avoid the thermal breaks

- During the construction, do not forget that the purchase of a few more centimetres of insulator request the same work of installation. Compared to potential energy savings, the surplus value therefore is negligible

- Support the installation of natural insulations such as the wool of sheep or the insulation with hemp for example

- Pay particular attention to the insulation, because a well-insulated house will content itself with a smaller, therefore less expensive, heating installation
