The first purpose of this study is to simulate the emission of life cycle greenhouse gas (GHG) including fluorocarbon leakage from thermal insulation of houses and comprehensively evaluate both the reduction of C0_2 emission by heating and cooling and the rise of GHG emission by fluorocarbon leakage. The results of the simulation are as follows; 1) Life cycle CO_2 emission by heating and cooling of 1999 standard is reduced by 50% than that of 1980 standard. 2) However, GHG emission including fluorocarbon leakage rises in some cases. The second purpose of this study is to forecast GHG emission by heating and cooling, manufacture of building materials and fluorocarbon leakage from all houses in Japan up to 2012. The results are as follows; 3) If the current situation continues, CO_2 emission by heating and cooling for the period 2008-2012 will rise by 9.9% compared to 1990 levels. 4) If thermal insulation of new housing is improved as rapidly as possible by 2010, it will rise by 9.1%, but however, GHG emission including fluorocarbon leakage will rise by 18.7%. 5) On the other hand, if measures for fluorocarbon leakage are taken, it could be reduced by 0.6%. 6) In addition to these measures, if thermal insulation of existing residential buildings is implemented, it could be reduced by 3.1%.
