In 2000, the domestic greenhouse gas emission in Japan was 1332 million tons of CO2, whichincreased by 8% in comparison with that of 1990. According to the Kyoto Protocol to the United NationsFramework Convention on Climate Change (COP3) held in December, 1997, Japan is obliged toreduce CO2 by 6%, compared with 1990. As a result, Japan is required to reduce by 14% (172 milliontons) on average during the period between 2008 and 2012. Particularly the emission in theresidential/commercial sector in 2000 was on the increase by 21.3%, compared with that of 1990. Moreefforts of emission control for housing and buildings are demanded.This paper aims to contribute to the introduction and promotion of the snow-and-ice cryogenic energy incold and heavy snowfall regions in the future. To achieve this goal, we have developed a new conceptfor improvement of the performance of a snow-and-ice cryogenic energy system.We propose an ice container system for the temporary space cooling. In 2006, space cooling wasoperated by using this ice container system. We evaluate the efficiency of space cooling.
