BioSkin, a system of perforated water-filled ceramic pipes that cools the exterior of buildings and their surrounding micro-climates, has won the 2014 Tall Building Innovation Award from the Council on Tall Buildings and Urban Habitat (CTBUH).
The initial use of BioSkin was at the NBF Osaki Building in Tokyo, completed in 2011.
Based on the traditional Japanese practice of sprinkling water to lower ambient temperatures and keep dust at bay, BioSkin absorbs heat through rainwater evaporation through a fine filigree of porous tubes, mitigating the urban heat island effect by cooling the building and its 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.

If many buildings in a city used such a system, ambient air temperature could be reduced to the point that even buildings without the system would benefit, CTBUH says.
"This is a remarkable faÃ§ade solution, both in its concept and how it has been beautifully detailed," said David Scott, Technical Awards Jury Chair and lead structural director of the Engineering Excellence Group at Laing O’Rourke, London, UK.Â
The CTBUH Innovation Award recognises a specific area of recent innovation in a tall building project that has been incorporated into the design, or implemented during construction, operation, or refurbishment.Â
Other finalists in the awards were One Central Park, Sydney, and Leadenhall Building, London.
