Abstract
To overcome the limitations of existing rainwater drainage systems, we compared and analyzed a newly developed eco-friendly channel-type rainwater drainage system. We also developed an integrated evaluation index to quantify the improvement of the new system. The concept of Life Cycle Assessment (LCA) was applied to calculate and compare the costs of each process and to develop the integrated evaluation index, which considers the carbon emissions by each process. As a result, the cost was reduced by 53% overall compared to an O-type system and by 63% compared to a U-type system. In addition, when applying the integrated evaluation index, the new system was evaluated to be over 80% in the four processes compared to the existing systems. When applying the evaluation index to sites in Anyang and Incheon, the new system was improved by 35-100% compared to existing systems.
