| Abstract |
The temperature of Busan Metropolitan City continues to rise, and abnormal climates such as heat waves, tropical nights, local torrential
downpours, and droughts appear in summer. The Ministry of Public Administration and Security is also recognizing and preparing for the
heat wave as a natural disaster situation. In particular, heat generated in the city center is blocked from air circulation to high-rise buildings,
and thus cannot escape to the outskirts, and is accumulated in the city center to increase the temperature again. Therefore, it is necessary to
respond to high-density and high-rise buildings. In the target of apartment complexes that occupy the highest proportion in Busan, research is
required to reduce temperature by improving sunlight and wind roads by adjusting the mass. Therefore, this study attempted to analyze the
changing microclimate in the complex by creating a wind path to prevent air congestion and forming an optimal shaded area by changing
the number of floors of apartment complex buildings, changing the dryness rate and the volume ratio, and changing the number of the same.
Targeting Busan Metropolitan City, a standard model for an apartment complex was constructed, weather data were processed and simulated,
and the temperature, wind speed, MRT, and PET for each scenario were checked. As a result, the CASE with a change in height and
daytime came out to have a lower temperature than CASE with a constant height and daytime. Not all height changes lead to temperature
reduction, but various height changes change the surrounding airflow, so the larger the height difference of the building, the stronger the
airflow in the complex. When deploying a building, the building should be placed in consideration of the main wind direction, but an
appropriate number of floors should be found to prevent stagnant airflow at high temperatures. It was also found that the lower the
building-to-land ratio, the higher the perforation rate, and the lower the total floor area, the less the urban heat island effect. |
