This research aims to investigate the influence of ventilation on indoor air quality and air change rate in healthcare facilities where contamination would likely have happened. The research method used a quantitative-descriptive approach and investigated a polyclinic waiting room according to the Regulation and Indonesian Standard, then analyzed using SPSS software. The result shows that some variables were not suitable with the standards caused by lack of natural ventilation, which also reduces the air change rate to comply with clean and healthy air quality. In line with that, air movement and volumetric airflow rate have a significant relationship with air change rate. Well-designed ventilation needs to be considered in the design process.
