        공동주택단지 재건축사업 전·후의 외부공간 온도 및 온열 쾌적성 비교 연구 - 서울 서초구 반포 주공 1,2,4주구를 대상으로 -

        Today, as abnormal climates such as heatwaves intensify, interest in the health of urban residents is increasing. Apartment houses, which have become representative housing types, are subject to renewal due to aging, causing new urban problems such as increased density. This study confirms the changes in temperature and PET before and after the renewal project through CFD simulation. As a result of the simulation by time zone, first, it was analyzed that the temperature increased after the project while the PET decreased. first, it was analyzed that the temperature increased after the renewal, while the PET decreased. Second, the decrease in PET at the pedestrian level was high between the Apt and Apt, and in the pilotis space. In addition, it was confirmed that the wind speed at the ground level increased due to the creation of pilotis. Third, it is understood that changes in the material of the outer space within the target site increased the temperature but affected the reduction of PET. Fourth, PET reduction in the outer space of the renewal complex was confirmed, and the creation of a cover park had no effect of temperature reduction, but had an effect on PET reduction. Fifth, the PET reduction in the surrounding schools of the complex was confirmed, there was a difference depending on the wind direction, and the PET reduction was confirmed when the wind direction was blowing from the complex. This study is meaningful in that it quantitatively simulated the change in terms of microclimate before and after the reconstruction project, and more detailed research is needed in the future.
