| Abstract |
This study, targeting the residential-commercial building which is recently emerging as the representative residential facility of urban area, analyzed the characteristics of environmental impact of input materials making up a building using LCA method, and constructed LCI DB for input materials. As a result of the analysis of Complex 8 (31 buildings), the average environmental impact of the residential-commercial building was found to be 9.67E-02 pe·yr/m2, being analyzed high in the order of civil (38.5%), architecture (33.1%), landscape (13.8%), mechanical (8.7%) and electric&telecommunication construction (5.9%). In addition, through the sensitivity analysis of the case buildings, this study selected major materials for 15 sorts of buildings, 3 sorts of civil construction, and 1 sort of landscape construction, and the average environmental impact of other materials excluding the selected major materials was analyzed as 2.48E-02pe·yr/m2 for a building, and 2.61E-02pe·yr/m2 for a site. |
