In the Var, episodes of intense heat are increasingly frequent and long. Before installing air conditioning, several levers can limit the heat entering the home and help remove it better.
Keep the sun out
A large part of the heat comes in through windows. Closing shutters or external blinds during hot hours, especially on façades facing east in the morning and west in the afternoon, is often the most effective step. External protection is far more effective than indoor curtains.
Insulate the roof
Under a sun-exposed tile roof, lofts can become very hot. Suitable insulation slows the passage of heat to the living spaces. Bedrooms under the roof are the first to benefit.
Ventilate at night
When the outside temperature drops in the evening and at night, opening wide and creating a draught removes the accumulated heat. Where nights stay warm, this effect is more limited.
Limit the heat produced indoors
Lighting, household appliances and standby devices give off heat. Shifting some uses to cooler hours helps comfort.
When air conditioning becomes useful
If, despite these measures, some rooms remain uncomfortable, well-sized reversible air conditioning takes over. It will be used less the better the home is shaded and insulated. Combined with solar panels, it can use part of the electricity produced during the day.
Frequently asked questions
Which room should I deal with first?
Bedrooms, particularly under the roof, because sleep quality is most affected by night-time heat.
Is a ceiling fan enough?
It improves the feeling of coolness without lowering the temperature. It is a useful addition, not a solution for severe overheating.
