Abstract
In environmental utility potential evaluation technique E2-PA, it is the quantitative evaluation technique of the environmental load which pursued and developed the standard nature as a decision-making support tool for a plan and a designer, and convenience. Comparison examination in consideration of the life cycle of the product which took part reuse, renewal, material recycling, etc., and the product which has not been taken in was performed. Moreover, the existing LCA technique also estimated the copying machine and it was compared with the evaluation result of E2-PA. As mentioned above, the validity of an inverse-system and the justification as the evaluation technique of E2-PA have been checked.
