- The air conditioning is very wasteful and can often be avoided, for example by planting trees (which lose their leaves in winter) to the south and the west of the house. Indeed, simple architectural choices can favourably influence one’s energy balance

- The use of radiant panels for the cooling of the buildings, coupled to a natural heat sink (ground water for example), can replace an air-conditioning system

- The choice of a too low temperature of cooling causes not only large consumption, but is also the origin of many useless blows of cold. Indeed, the regulation of the temperature should take account of the outside temperature: thus, if it makes 31°C outside, it is absolutely not necessary to air-condition a room with 20°C

- At the time of the installation of an air-conditioner, take care that a professional lays it out
