Heatwave in Paris: the concrete that cooks its tenants

Published on June 28, 2026 | Translated from Spanish

In the northern suburbs of Paris, two concrete housing complexes face an extreme summer. Without blinds or ventilation, residents endure unbearable temperatures in their homes. The lack of investment in decent housing worsens health and well-being issues. The solution is urgent: install basic solar protections to prevent the suffering of thousands of people.

Emergency architecture: how an awning can save lives 🌡️

The technical solution involves installing retractable awnings or exterior aluminum blinds with solar reflectivity. These systems, low-cost and easy to install, reduce indoor temperature by up to 10 degrees. They can also be combined with reflective paints on facades and cross ventilation. However, the lack of municipal budget and bureaucracy hinder these measures. Meanwhile, residents use wet sheets or take refuge in shopping centers.

The innovative climate control system: open the fridge and sit inside 🧊

Tenants have developed their own cutting-edge technology: the open fridge method. It consists of opening the appliance and sitting in front of it, which lowers body temperature but raises the electricity bill. Others have opted for second-hand portable air conditioning, which sounds like a tractor. Authorities, meanwhile, are studying whether installing awnings is viable or if they prefer to wait until next winter to forget the problem.
