Imagine cooling your home for free—no electricity required! That’s exactly what this age-old material, terracotta, can do.⁠
⁠
People are finding creative ways to bring this natural cooling method back into modern life. Used for centuries from Spain to China, terracotta is making a comeback as architects look for energy-saving alternatives to traditional air conditioning.⁠
⁠
Terracotta roof tiles, for example, trap cool air and use tiny pores to circulate it throughout a building. Facades made from terracotta act as thermal shields, keeping interiors warm in winter and cool in summer. The same goes for bricks and floor tiles crafted from this material.
⁠
In India, CoolAnt has engineered a terracotta air conditioner that works without any electricity. Their design uses hollow cones soaked in water; as the water evaporates, it chills the air drawn in by the cones.⁠
⁠
Terracotta is abundant worldwide, making it accessible for many communities. Plus, it’s eco-friendly—when it’s no longer needed, it can be broken down and returned to the earth or reused.⁠
⁠
With all these benefits, is it time we embrace terracotta again for sustainable cooling?⁠
