Application of LID to the District Unit Plan and Mixed-Use Buildings: Focusing on the Case of the 1-5 Living Area in MAC

Abstract

The purpose of this study is to introduce the procedure to apply LID (Low Impact Development) in developing the master plan for the mixed-use residential buildings to be built at three blocks (H5, H6, H9) in the 1-5 Living Area in the Multifunctional Administrative City. The legal background of the district unit plan was revised by adding new clauses for the definition of LID and rainwater circulation system where LID is applied. Based on the revised district unit plan regulations, several LID technologies which were appropriate for each block were selected, and they were reflected in the master plan and design guideline as a part of the rainwater circulation system. After the design guideline was developed in detail, a company that will develop the design and build was selected through a design competition. As of 2020, these mixed-use residential buildings are under construction. Once they are built and used by occupants, they will enable researchers to empirically evaluate the benefits of LID by showing how rainwater circulates and how LID works in the building and area.
