BioSkin, a building façade technology developed by Nikken Sekkei and initially used on Tokyo’s NBF Osaki high-rise, has received an innovation award from the Council on Tall Buildings and Urban Habitat. What’s special about BioSkin? We’ll let the CTBUH explain why it’s so potentially revolutionary:
Based on the traditional Japanese practice of uchimizu, the sprinkling of water to lower ambient temperatures, clean the streets and keep dust at bay, BioSkin absorbs heat through rainwater evaporation, mitigating the urban heat island effect by cooling the building as well as its immediate surroundings. Through this process, the surface temperature of the building enclosure can be reduced by as much as 12°C and its micro-climate by about 2°C. The potential implications of this are substantial: If a large number of buildings in a city used such a system, ambient air temperature could be reduced to the point that cooling loads for many buildings, even those without the system installed, could be reduced.
Skyscrapers as urban oases? We love that. Learn more about BioSkin at the Nikken Sekkei website.
