A study on the major construction materials of non-residential buildings from the viewpoint of major environmental impact

Abstract

The purpose of this study is to perform LCA (Life Cycle Assessment) more efficiently in the non-residential building field which is not different from residential building. For that reason, we will improve the efficiency of LCA for non-residential buildings by analyzing the key building materials that we must know to assessment. The main materials derived from this study include RMC, Rebar, Steel Frame, Glass, Brick, Cement, Aggregate and Iron in common. In addition, the general building has Gypsum, and the commercial building has stone as the ninth major material. By replacing the derived materials with the values of the three environmental impacts required by the Korean green building certification system G-SEED, it is possible to check the errors compared with the values already evaluated in the practical work and verify that they are applicable in actual work. As a result, it was analyzed that the materials derived from this study alone are sufficient to carry out LCA. If LCA is performed using these main materials, it is expected to be more efficient in terms of time and cost. © International Journal of Sustainable Building Technology and Urban Development.
