STUDY ON LCA OF LCCM ORIENTED HOUSES

The analysis method for feasibility of CO₂ reduction goal with taking into account the uncertainty and the accuracy of the data

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.
