Energy consumption and CO_2 emission due to construction of buildings in China and Japan are described in this report. As more than 400 industrial sectors are contained in Japanese IO table and 30 sectors in Chinese IO tables, energy consumption and CO_2 intensities of dominant materials used in building are derived from energy consumption in factories and equipments are derived from IO analysis. Energy and CO_2 intensities of main materials used in building construction in China and Japan and the calculation methods are shown in this report. Office buildings in both countries are calculated as a case study. The intensities of materials in China are 2-3 times larger than Japan and energy consumption and CO_2 emission due to construction of office building in China is 10-20% larger than in Japan. Though energy consumption of structure in China is 2-3 times larger than in Japan, interior finish works and equipments for air conditioning etc. are smaller. Energy consumption due to Chinese office building construction are almost same as Japanese.
