Starting in 2010, the New Chitose Airport in Hokkaido, Japan will collect snow in the winter to provide 30% of the terminal building’s cooling needs 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. According to Japan Today, the practice could result in a 2,100 ton reduction in CO2 emissions per year.
This process isn’t new to Hokkaido, Japan’s northernmost island, which receives between 20 and 30 feet of snowfall a year. The island has been experimenting with cooling systems using their icy resource since 1998 and has already installed systems in smaller public buildings.
