Abstract
Resource consumption intensities are analyzed based on 2000 Japanese Input-Output Tables. The intensities include direct resource input and extension effect and are calculated for 399 sectors of materials and services. These intensities enable calculation of resource consumption and resource productivity of buildings. The result is shown that the resource productivity in 2000 is a decrease 9% compared with 1995. Additionally intensities of eco-materials such as hot rolled sheet steel, eco-cement and recycled aggregate concrete are analyzed. Thus, it is presented that the use of these eco-materials would increase the resource productivity of buildings by the maximum of 30%.
