Exploring the Influence of Building Mass Configuration on Urban Airflow, Case Study: Pulmonary Hospital Salatiga

Abstract

This study investigates the influence of building mass configuration on urban airflow dynamics on a case study the development of dr. Ario Wirawan Pulmonary Hospital in Salatiga. The development involves expanding the facilities with new building additions. This development raises concerns about potential disruptions to the air circulation patterns that may have an effect on the health level of its users. This study uses Computational Fluid Dynamics (CFD) simulations with Rhinoceros for 3D model and the Grasshopper with Butterfly plugins to investigate the influence of building mass configuration on urban airflow dynamics. By comparing the existing hospital conditions with the proposed developments, this study show the changes in air circulation direction and wind speed. The results of this study indicate that the development of the hospital causes a decrease in wind speed in development. The average value of the existing wind speed is up to 0.7 m/s faster compared to the new development condition. The study result highlight the importance of strategic planning and building design to ensure the optimal air circulations within healthcare facilities.
