Terracotta Valley Wind

Inspired by MuscaTese, Terracotta Valley Wind is designed to provide a passive cooling system for subway stations during the summer. By making use of the induced wind from arriving or departing subway trains, the station can be cooled down in a natural and low carbon way, eliminating the need for air-conditioning and reducing energy consumption. Terracotta tiles, steel frames, rubber components, and floating ball valves make up the system. Rubber components help to stabilise the clay and create the water tunnel. Valves allow water in the tunnel to maintain a constant level, supplying water to the tiles continuously. Through capillary action, water passively penetrates the entire terracotta tile from the bottom. The porous nature of terracotta allows water to quickly move through the walls and evaporate, removing the heat from the surrounding environment. When subway trains arrive and the wind passes over its surface, the tiles cool the induced wind and direct the cool air to the platform area. Meanwhile, the train’s motion propels air circulation above and below ground. The hot and humid air inside the station will be exhausted to maintain a comfortable environment. The shape of the terracotta tiles is intended to guide train-induced wind while increasing contact area with the wind. Each tile can be easily assembled and replaced.
