조경 식재 방식에 따른 공동주택단지 보행구역의 빌딩풍 변화 분석

초록

The purpose of this study is to evaluate the building wind reduction in the residential community by the planting method. Planting at the boundary region and the partial districts of the target site are considered. The simulation is performed by CFD tool, Star-CCM+. The results show that planting at the boundary of the region generally results in the significantly wind speed reduction around the boundary planting position. However this type of planting does not reduce the wind speed significantly at middle area of the site because of the down-ward airflow generated by the tall building facade. Planting at the partial placement in the residential community slightly reduce the wind speed at target area. However, undesirable wind speed increases at other parts were occurred. According to the results, the planting method affects the wind speed reduction effect. When the trees are spread at the target area, wind speed is reduced effectively. Basing on the results, we can also conclude that planting at the boundary region and specific district are useful for wind speed reduction at the target site.
