Summer, the other season of discomfort

Did you think you survived the freezing winter in your poorly isolated accommodation? Summer reserves another torture for you. For owners and donors Thermal mouthsThe increase in temperatures transforms these goods into real ovens. Among repeated torrid summers, increasingly rigid and growing energy regulations of the occupants, the urgency of the energy renewal Not only did he live in the cold season. It also burns under the sun.

Heat that no longer forgives

Heat waves are no longer an exception. In 2023, France experienced 22 days of wave of heat second Météo Francemost of which are traditionally the hottest months. However, in the accommodation classified for G A Diagnosis of energy performance (DPE)The absence ofThermal insulation Effective transforms the penthouse, walls and windows into giant radiators.

During the day, the internal temperature can easily exceed 30 ° C. at night, the absence of sufficient natural or mechanical ventilation prevents refreshment arrangement. Result: the occupants sleep badly, convey constantly, flee from their home or multiply the emergency equipment.

Air conditioning, fans, permanently closed roller shutters … so many temporary responses to a structural problem. But they have a cost: energy invoice Heavier and higher and more persistent discomfort.

Summer Thermal Sterlanders: a double penalty for the occupants

THE thermal coach It is often seen as winter hell. However, in the summer, the feeling of suffocation becomes psychologically and physically. Nathalie, 62, retired to Nîmes, says:
«I live alone and from 11 I can no longer stay in my living room. It is warmer than outside. I had to buy a mobile air conditioning for € 400, but it's not enough.» «

Thermal discomfort can become an aggravating factor for the fragile audience: the elderly, small children, chronic patients. And unlike winter, there is no financial help to fight against the heat.

On the health side, the effects are real: headache, fatigue, irritability, sleep disorders. A spiral that also weighs on the value of use of the property and strengthens thethermal exclusion.

Boomerang effect on rental value and vacancies

For them ownersThe combustion of summers can also have a direct impact on profitability. A tenant who suffocates with him is a tenant who complains, negotiate or part. From the ban on rent in the shape of Gs classified by 2025, the Rents market It becomes more demanding, especially in urban and tense areas.

The summer vacant place, often perceived as temporary, can be transformed into a non -renewal of leasing or rejection of the candidacy. In Paris, Lyon or Toulouse, young workers prefer goods with balcony, Cross ventilationOR Performing insulation. The accommodation without summer comfort are now a good that devalues.

Some ads already include the level of summer thermal comfort as a differentiation criterion. And this will increase only.

A little exploited lever: summer insulation

Most of the energy renovation works are designed for winter: heat pumpIsolation of the attic to maintain the heat, replacement of the windows to limit the losses. However, these works must also integrate a Summer comfort strategy.

TheThermal insulation chosen must offer a file sufficient inertiaThat is to slow down the entrance of the heat during the day. There wooden wool or theaérogelFor example, it has better performance for this type of use than simple glass wool.

THE thermal balance or theEnergy audit It becomes a key tool to understand the weaknesses of the accommodation in front of the heat. And in some regions, the installation of photovoltaic cells It can partly cover the electricity requirements for refreshing equipment.

Financial help: still too shot in winter

THE energy renewal Summer still lacks specific support. Help like Maprimerine 'THE Energy saving certificates (EEC) or theEco -ptz Stay centered on heating saving. However, with a summer which extends from two to three weeks for decade according to theNational Observatory on the effects of global warmingit becomes urgent to adapt the devices.

Some innovan communities: the Azur's arrival-alpes-côte region has been financial since 2024 a support program on Summer comfort. But these initiatives remain marginal in the face of the extent of the challenge.

The owners who occupy donors must integrate these problems in their heritage strategy, not as a bonus, but as a need for survival for rent and health.

What I remember from the summer thermal inclination

Summer discomfort in a thermal colander is no longer an embarrassing detail: it is an obsolescence detector. The repeated heat waves accelerate the devaluation of poorly isolated assets, strengthen the inequalities of access to healthy homes and impose a complete reconfiguration of the renewal policies.

At a time when the state tightens the screw on the rental criteria, when young workers flee from suffocating housing and when the elderly suffer in silence, do not do anything is no longer an option.
Summer thermal comfort must become a Called real estate indicatorIn the same way as the DPE label or the level of loads.

Owners, donors: start with a complete audit including the risks ofsummer discomfort. So adapt your isolation, ventilation and equipment choices accordingly. I don't only invest in buildings, but in vitability Lasting your inheritance.
