Heatwaves in France are impacting public health, local economies, and real estate trends. Initially, extreme heat led to a surge in swimming pool usage, creating health hazards such as the formation of chloramines and the growth of bacteria like E. coli. This increased demand also fostered a rental market where private pool owners use digital platforms to lease their facilities to the public.

As the heatwaves persist, the impact has extended to the real estate sector. In France, prospective homebuyers are increasingly prioritizing thermal comfort, seeking properties with air conditioning, cross-ventilation, shutters, and shade. Traditional features like southern exposure are losing appeal due to intense sun exposure, while homes lacking cooling infrastructure face difficulties in the market.

In Germany, rising temperatures are affecting the rental sector and building standards. In Hamburg, the Mieterverein (Tenants' Association) reports an increase in inquiries from residents, particularly those in attic apartments, who struggle with extreme heat. While the German Tenants' Association is calling for legislation to establish a 26-degree Celsius maximum temperature limit, legal recourse for rent reductions remains difficult because there are no statutory maximum indoor temperature limits.

Furthermore, the German real estate industry is addressing building heat protection. Because built-in air conditioning is relatively rare in Germany, companies like City 1 Group are emphasizing structural solutions. For example, at their Epsilon Office in Neu-Isenburg, they utilize external blinds to intercept solar radiation, high ceilings, and full air conditioning. They note that investing in long-term solutions like external blinds is more cost-effective over twenty years than cheaper internal alternatives. Legally, German rental law follows a ‘construction principle,’ where tenants rent based on thermal standards present at the time of construction, and tenants face restrictions on modifying structures or installing external units without landlord consent.
