미기후 분석을 통한 노후 공개공지 리모델링 개선방안 : 금천구 W센터를 중심으로

Abstract

Purpose: In this study, ENVI-met simulation was performed on one of the work facilities that had been remodeled for public notice before and after public notice. Through this process, we assessed the weather conditions and thermal comfort in summer and winter respectively. Through this process, the government intends to contribute to the improvement of the relevant system by suggesting improvement measures considering the weather conditions and the warm environment in remodeling the old public spaces. Method: The analysis target for this study was the W Center in Geumcheon-gu, Seoul, which was selected as a model case for improving the shelter in cooperation between the public and private sectors among eight locations for the remodeling of public spaces in Seoul in 2015. The process and status of remodeling of the target area were reviewed, and basic data of the main wind direction and the air environment were collected through AWS (Automatic Meteorological Observation Equipment). ENVI-met simulation was used to assess external spatial characteristics quantitatively due to difficulties in analyzing the environment of public notice before and after remodeling. Through this analysis, the unpolished environment and thermal comfort of public spaces were analyzed. The time range was set for the afternoon of June 21, 2018 and December 22, 2018. Result: The outer space of the existing destination was paved with red sidewalk blocks, and it had aged due to street numbers and broken fountains. On the other hand, white sidewalk blocks and abundant green spaces were created in the outer space that was improved through remodeling. These major improvements have resulted in lower temperatures of 1 to 2℃ in summer and lower heat comfort by 0.1 to 0.2°, which has positive effects on environmental improvement. The improvement of the weather conditions has resulted in partial improvement of the thermal environment in the surrounding outer space. On the other hand, the results of winter’s climate analysis and thermal comfort showed no marked difference. This shows that the weather conditions in summer should be considered actively when planning the remodeling design of old public spaces.
