Cool bricks are three-dimensional porous ceramic bricks that use evaporative cooling to provide a cooling effect across the environment. The porous ceramic bricks connect to create a 3D lattice pattern. The porous material absorbs water that is discharged after the passage of warm air from the outside into the lattice.
The developers of cool bricks are a California-based studio that focuses on innovation in 3D printing of architectural and building components. The goal of cool bricks is to contribute as a technology that enhances cooling performance and construction durability.
Cool Bricks Evaporative Cooling System
The notion of an evaporating cooling mechanism in cool bricks was employed as far back as 2500 B.C. The procedure involves the introduction of water vapour into the air, which results in a reduction in air temperature. This principle was employed in ancient times to chill water by evaporation through porous pottery jars in desert environments. As a result, the cooling brick system approximates the action of water-filled ceramic containers.
When air passes through the lattice structure of the brick, the water held in the micro-pores evaporates, which might carry cold air into the indoor environment. This lowers the outdoor temperature through the method of evaporative cooling.

The brick’s shape is meant to maximize the fraction of the surface that is shaded from the sun, hence improving cooling efficacy. When these bricks are placed together, they provide an effective screen.
Cool Bricks Advantages and Uses in Building Construction
The cool brick is made of low-cost materials and is easily produced, making it an excellent alternative for delivering a comfortable indoor environment in nations such as the Middle East and Western Australia.
A passive building system has several passive building alternatives.
A cooling brick is a porous ceramic brick that has been 3D printed and is kept together using mortar. It is a three-dimensional lattice that is a hybrid of a ceramic lightweight slab and a wooden lattice that allows air to move through the perforations.
In technical words, the Evaporative cooling effect occurs when hot air travels through water, adding moisture to the air, resulting in a temperature drop and cooler, fresh air. This phenomenon was extensively implicated in cooling effects before refrigeration was discovered. Walking back in time to 2500 BC and analysing architectural features would cast a shadow on slaves fanning jars of water used in frescoes to cool a space, bringing to light the ancestral use of Evaporative cooling.
The bricks are modular, and they can be interlocked using mortar to form a strong bond and form a wall surface. The stacking of modules generates a screen-like structure that shadows a substantial percentage of the wall surface, boosting the cooling impact and providing sun protection, resulting in improved cooling brick wall performance. And the benefits don’t stop there; it doesn’t require any moulds or formwork, and the modules stack up like legos, reducing waste production – a step toward a sustainable construction design.
Cooling bricks are a low-cost material that can be simply made and utilised to improve handy building construction processes with a good influence on the environment and comfortable environments in the interiors. This energy-efficient technology is best suited for hot and dry places where air conditioning is essential for survival during peak season, and the cooling brick can be a game changer.
