Crafted with the idea of "improving the environment with large-scale architecture," and inspired by traditional Japanese air-cooling techniques, Nikken Sekkei set out to build the world's first "blind-like" exterior system that reduces heat in the building's vicinity on the entire east wall of the 25-story Sony City Osaki office building.

Sony City Osaki office building. This building is the first structure to use BIOSKIN a new exterior system based on the principles behind sudare, or traditional Japanese screens.

Nikken Sekkei utilized Cradle's scSTREAM, a General Purpose Thermo-fluid Analysis System with Structured Mesh, to simulate the environment and discover the effects of the BioSkin technology. For the simulation, the data was comprised of information from Tokyo University, and temperature simulations were performed under the conditions of a summer day with prevailing wind. Other buildings in the area and the surface temperature of nearby roads were also taken into account. The end result of the simulation was a prediction of a 2-degree celsius drop in temperature around the entrance to the model.
