Starting in 2010, the New Chitose Airport in Hokkaido, Japan will collect snow in the winter to cool the terminal building in the summer. The snow will be covered by heat-insulating materials, which should retain about 45% of the snow collected. The remaining snow will then be used to chill the liquid of the building’s cooling system. The process could result in a 2,100 ton reduction in CO2 emissions every year.
