Do Not Overheat, Do Not Freshen
During fresh seasons, pay attention not to overheat your home. We recommend a temperature of 20° in living rooms, and 19° in the rooms. It is useless to heat more. One more degree equals 7 to 11% more energy spending. If 20° seems too fresh during the day, do not forget to lower the heating at night.
Inversely, during hot seasons, pay attention not to freshen the rooms! The temperature of 20° in the living rooms is not necessarily the best when it is hot outside. In case of high heat, pay attention not to strongly turn on the air-conditioning, for it consumes a lot of energy and provokes harmful cold snaps. A difference of six degrees between the outside and the living rooms of the house is recommended in order not to undergo thermal chocks when you enter your home, and to limit the increased spending of energy.
While buying an air-conditioner pay attention to its energetic output.
