How Seville Stays Cool Despite Rising Heat

Climate change is increasing the average temperatures of cities around the world, which forces inhabitants to adjust to entirely new climates their cities weren’t designed for. In Spain, the city of Seville is expected to have the climate of Marrakesh in a few years time so the city needs to find new ways to cool down. They are currently experimenting with an old technique perfect by ancient people: use water that cools in the night to cool the city during the day.

One of the coolest spots in Seville, Spain, is the site of CartujaQanat, an architectural experiment in cooling solutions that relies not on air conditioning but on natural techniques and materials. Inspired by ancient tunnels dug to bring water to agricultural fields in what is today Iran, the $5.6 million structure uses a network of aqueducts, pipes and solar-powered pumps to cool water at night and then turn it into cold air during the day.

Seville is among the world’s hottest cities looking for new ways to cool down and save lives. Yet despite the project’s early promises, the CartujaQanat remains in limbo amid financial and political hurdles, Laura Millan reports.
