| Abstract: | Basic sector classification Input/Output Tables of Japan (Research Committee of International Trade and Industry, Tokyo, Japan, 1988) were applied to quantify the total energy consumption and CO2 emission including direct and indirect effects due to the construction of various types of houses. As a result, energy consumption for construction is calculated as 8–10 GJ per square meter of floor area for multi-family SRC (steel reinforced concrete) houses, 3 GJ for wooden single-family houses, 4.5 GJ for lightweight steel structure single-family houses. CO2 emission resulting from construction is 850, 250 and 400 kg/m2, respectively. |
