Abstract
A simplified calculation method of resource and energy consumption, and CO_2 emission is proposed. These intensities are based on 1995 input/output table in Japan. This method is applied to sample buildings. The results of material consumption calculated by this simplified method and detailed method are almost in substantial agreement in one of the buildings, and disagreement in the other. The reason is that the consumption of temporally road construction of sample building is different from that of intensity calculation. The resource consumption in structure work is 80% of total consumption and in mechanical and electrical work is only 7% of total consumption.
