We’ve previously seen designers use the presence of swimming pools or take advantage of prevailing winds to help passively cool homes. But what if every brick used to build a house could cool it down?
Design studio Emerging Objects has come out with 3D-printed porous bricks called Cool Bricks that can be filled with water to bring down temperatures.
The bricks utilize the principle of evaporative cooling, where water vapor is added to air to lower the temperature. If you’ve ever hung a wet cloth in front of the window to cool the breeze flowing in, you’ve used the same principle.
Each 3D-printed cool brick, has a three dimensional ceramic lattice-like structure that can hold water in its pores, like a sponge. When air flows through the porous brick it absorbs evaporated water vapor, becoming cooler in the process. According to the designers, if all the walls of a home were built with porous, water-logged cool bricks, the air flow through them could bring down the home’s internal temperature.
“It’s an alternative to air conditioning or an electric swamp cooler,” Ronald Rael, one of the designers, tells Gizmag. “It is a much more natural, energy-saving tactic for passive cooling in arid environments.”
