Study on LCA of LCCM oriented houses

Abstract

In this study, we provided a confidence interval for LCCO2 taking account of a difference between the amount of building materials which are estimated, ordered and used, a difference in repair of levels and period and an error of LCA data. In this estimation, 95% confidential interval of the LCCO2 is from 283kg-CO2/m2 to 3,126kg-CO2/m2. Secondly, we verified feasibility of LCCM by the CO2 balance among a reduction from 8kW-PV, an energy consumption and the confidence interval. Lastly we clarified an interrelation between a probability of feasibility of LCCM and a reduction of CO2 of energy generating facilities.
