New Japanese airport will be cooled with snow

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 abundantly icy resource since 1998 and has already installed systems in smaller public buildings.

    How much energy would it take to construct this addition? Compared to the masses of C02 given off by airports, will this amount avoided be relevant in any way?

    supposedly there is no such thing as a stupid question but the above post comes close. Its that kind of questioning that is slowing down the construction of local wind powered generators in our county, the benifit is substatial the benifits obviouse, but it might kill a few birds, damn. your questioning the energy cost of a structure that will last decades and pay for itself time and again in energy reduction and cooling cost reduction. I bet it's energy cost to build is a hell of allot less than one of those 747's flights from here to there out there on the tarmac
