In their attempt to look for sustainable and affordable building solutions, architects Johanna Navarro and Miguel Niño, of Colombia-based Sumart Diseño y Arquitectura SAS, have developed Bloque Termodisipador (BT) – a special type of clay brick whose smart angled design reduces the amount of heat entering the interior of a house, while also ensuring increased ventilation through the perforations present inside it. Furthermore, this ingeniously-crafted ceramic block help decrease material wastage as well as construction time.
Unlike regular bricks that are uniform in shape, the BT – Bloque Termodisipador has an asymmetrical, five-sided shape, comprised of a rectangle and a scalene triangle. According to the developers, its angled form actually protects the brick from harsh solar radiation, and also minimizes the amount of heat permeating into the building. On the inside, the block features a highly porous cellular structure that in turn allows air to pass through, thus ensuring proper dissipation of heat. What is more, pouring water into these channels can increase the cooling effect through evaporation. Speaking about their creation, the architects said:
With traditional fired clay bricks, heat is transferred in one direction, due to the horizontal surfaces that make up the channels in the bricks, acting as thermal bridges that conduct the heat to the inside at a greater speed. The horizontal surfaces of the BT – Bloque Termodisipador are interrupted by a series of smaller sub-channels, making it so the path of the heat is longer, and slowing and reducing its entrance inside.
The brick’s irregular shape also help reduce the amount of traffic noise that reaches the building’s interior. It can be used to erect different types of three-dimensional enclosures and facades, and can even be combined with traditional flat bricks in wall construction. Each block comes with a groove for holding a specific amount of the mortar. This ensures minimal wastage of materials, thereby bringing down construction costs. The BT’s shining, natural finish eliminates the need for painting, while a joint spacer achieves uniformity between two bricks by leaving the triangular part free of any adhesive.
