We analyzed the energy consumption structure and air pollutants, Greenhouse gases emissions from residential houses in Japan in fiscal year 2000. In this paper estimation methodologies are discussed and only energy consumption and CO_2 emissions estimation results are shown. The detailed high dimensional energy consumption data and emissions inventory data are consist of 4 dimensional data matrix, by prefecture including ordinance-designated cities, energy type i.e. fuel and electricity, thermal end use type, and residential building type, i.e. detached house or flat type. The key points of this estimation methodology are (a) improvement of estimation process of LPG and kerosene using consumption survey Data by Oil information Center. (b) Distribution to thermal end use type using monthly trend and so on. (c) Distribution to residential building type based on the space heat load simulation on the standard model houses using SMASH soft ware. Summary of the estimation results are (1) Total residential energy consumption is 2,040PJ high calorific value base, its total CO_2 emission is 159 Tg(10^6ton)CO_2, of which 71% energy and also 71% CO_2 is coming from detached house. The estimated energy consumptions data and emissions inventory data are applicable to several kinds of analysis for the evaluation of emission reduction options.
