本研究は中国と日本における建築工事に伴うエネルギー消費量と CO_2排出量を計算したものである。得られた成果を要約すると、 1）中国における30部門産業連関表と部門別エネルギー消費量から、 100万元当たりのエネルギー消費量とCO_2排出量を計算した。建 築の主要材料に関しては製造に必要なエネルギー消費量とCO_2排 出量を積み上げ法で求めた。産業連関分析は100万元当たりの値 であり、主要材料は重量あるいは体積当たりの値である。これら を原単位の一覧表としてまとめた。%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.
