Which mix of material and geometry cools best and still survives Dutch winter frost?

Bertalan Ivan with a team of three, Future Materials course, TU Delft
Material
Clay with used coffee grounds, printed and fired
Place
Rotterdam as context, tests in Delft

Air conditioners in Rotterdam push heat into the street. The team designed a passive evaporative cooling panel that fits onto existing units. Used coffee grounds from local waste burn away in the kiln and leave a porous ceramic that takes up water fast, and adjusted mixes and firing keep it frost resistant. Printed geometries give a very high surface for evaporation; the team tested them in its own climate chamber.
