Although the population of Japan is going to decrease, the energy consumption of the residential sector is assumed to increase. On the other hand, new construction will decrease gradually, and the ratio of the existing houses in housing market will grow up. Therefore it would be very important to reduce the energy consumption of the existing houses. This study estimates household CO2 emission between 2005 and 2050 in Fukuoka. This paper aims to clarify reduction effect of environmental load by administrating each measures. The results of our analysis are as follows. 1)Effects of measures to existing houses are 0.8-2.5% larger than to newly built houses. 2)Housing policies can contribute to reduce CO2 emission by extending the lifetime of houses and promoting multifamily housing.
