This building is the first structure to use BIOSKIN a new exterior system based on the principles behind sudare, or traditional Japanese screens. BIOSKIN reduces the heat island effect by cooling the exterior of the building with rainwater collected from the roof area by feeding it through special porous ceramic pipes. As the water evaporates, it reduces the surface temperature of the ceramic pipes and the adjacent air. Based on experiments and simulations, it is estimated that the temperature of the surrounding air can be lowered by about 2°C. In addition to natural cooling effects, the BIOSKIN sudare screens out direct sunlight, reducing air-conditioning load for greater decreases in CO2 emissions.
