A Study on the Airflow Analysis for Housing Redevelopment Project

Abstract

Background/Objectives: The industrialization and urbanization increased the number of people entering the city, and the city had to suggest ways to secure housing as the population grew. Therefore, the results of this study may suggest ways to minimize airflow congestion that may occur in a residential redevelopment project or in a planned area.

Methods/Statistical analysis: This study is to analyze the airflow change of the redevelopment block when the poor building in the downtown area is developed as a high-rise building through redevelopment project. For analysis, program used is ECOTECT analysis, an eco-friendly design and environment analysis program.

Findings: In low-rise housing complexes that do not have sufficient distance before the housing redevelopment project, airflow is often stagnated or the airflow speed is less than 0.5 m/s. This seems to have the effect of preventing the cold wind in winter , but in urban heat island phenomena, if the airflow stagnates and fails to pass, it increase the atmospheric temperature and causes the urban heat island phenomenon. After the housing redevelopment project, the gap between building and building is widened, so that the airflow in not stagnant in general, and it is possible to reduce the rise of atmospheric heat that can occur in summer and reduce the occurrence of urban heat island phenomenon in winter. It is necessary to suggest ways to plant trees and change the layout of building to prevent airflow.

Improvements/Applications: This study is can be used as basic data to analyze the phenomenon of housing redevelopment project in urban heat island phenomenon in urban areas where artificial structure are densely distributed.
