A situation “emergency” Who led him to work, with deputies of different political edges (together for the Republic, Ecologists, Socialists, La France rebellious) on a bill aimed at accelerating the renovation of “ottering housing”, by analogy with the thermal coators, these very poorly insulated dwellings noted E, F and G on the diagnosis of energy performance (DPE).

LED lighting and ceiling fans

While the housing foundation assimilated the kettles At the “zero degree of public action”, the Minister of Housing, Valérie Létard, wishes to develop the DPE so that he better integrates the concept of summer comfort. The ministry must make proposals to this effect during the summer. In the meantime, you regret having further postponed the installation of an air conditioning in your apartment due to its cost. Is to forget “That there are some simple tips and work thanks to which we have noted a gap from 7 to 10 degrees Between the outside temperature and that of a housing in summer ”underlines the startup Little Worker, specializing in real estate renovation.

Start with the ba ba, that is to say by Limit heat emissionsin particular those, very important, coming from household appliances. Avoid for example to run washing machine and dishwasher in the middle of a dodge at 3 pm! And opt for lighting with LEDs (electroluminescent diodes), which give off less heat than conventional bulbs. Do you find out the fans that your parents-in-law installed on the ceiling of their living room? You are wrong. “Thanks to its pale, the ceiling fan raises the fresh air and quickly refreshes the room, up to minus 6 degrees »assures Little Worker, greeting a “Ecological, not very noisy and aesthetic solution”don’t like it.

Hill the windows

More broadly, the ventilation,, “Often neglected, allows, thanks to a control of controlled air in the accommodation, to regulate the humidity of the air and to benefit from real comfort throughout the year”says Little Worker. So make sure your VMC (mechanical ventilation) works! Another measure not very complicated to sleep in the fridge if you are about to move: “Eco-design”. It is simply a question of taking care not to install your room in a room located south. And too bad for the view of the garden! Also do not impasse on curtains even if it is more trendy to display bare windows: “L’concealment Allows you to wedge the heat between the curtain and the glass »recalls the start-up. Occultation is also outside: it also specialized in energy renovation, the company Hello Watt offers “Systematically” to its customers the installation of shutters.

Regarding the very windows, “Opt for double glazing is beneficial to maintain interior temperatures, both in summer and winter ”recalls Little Worker. We grant you, these are more expensive works, to consider perhaps rather for the summer of 2026. Ditto for the insulation of the walls and the roof, however “Crucial to maintain freshness in your accommodation during the summer”hammers the start-up.

Isolate with bio -based materials

This suggests investing, “As far as possible, in Biosourced insulation»»the most effective to guarantee a significant thermal shifting, that is to say the duration put by heat to cross a material. The more the heat takes time to cross the insulation, the more the accommodation remains in the fridge. For example, wood wool guarantees eight hours of phase shift, twice as much as expanded polystyrene.
