공동주택 저층부 식재배치 계획에 따른 미세먼지 저감 효과 분석 : 서울시 리모델링 공동주택 실증단지를 중심으로

Abstract

Purpose: In Korea, since industrialization through compressed growth in the 1970s, population growth and urban concentration have emerged, resulting in a variety of environmental problems. Among them, fine dust has recently been recognized as a serious environmental problem, raising its risk and alertness. In the construction sector, pedestrian-first outer space was planned in low-rise areas to remodel sustainable apartment complexes. This method is the right way to create a pleasant external environment in an apartment house by creating an open space and recording in an external space. Method: In this study, a study was conducted on the arrangement of low-rise plants to reduce fine dust in one apartment complex where remodeling was conducted. Trees those are effective in reducing fine dust have the ability to absorb fine dust and settle fine dust when it rains. In particular, conifers were found to have better performance than broad-leaved trees. We selected two types of conifers and set up an equation for how much fine dust remains depending on the planting density. Result: The conclusions of the study are as follows. First, the microclimate environment was improved due to changes in the low-rise space when remodeling old apartments. Second, the rate of fine dust removal in the complex was found to be effective when setting up trees and shrubs as coniferous trees that are excellent for reducing fine dust. Third, if the wind speed is maintained at a certain speed, it is excellent for reducing fine dust. This study is meaningful in suggesting the right external space landscaping measures in the Seoul Metropolitan City Remodeling Policy Direction, which will make the low-rise a pedestrian-centered nature-friendly space when remodeling old apartments in the future.
