N2 - Airborne transmission within hospitals contribute to outbreaks. Computational simulations are useful in evaluating and optimizing the ventilation strategies in indoor environments. However, such approach can be computationally expensive and resource-intensive. To address this, this study employed a computational fluid dynamics (CFD) model coupled with a genetic algorithm (GA) to optimize ventilation strategies that minimize the risk of infectious pathogen deposition in a general inpatient ward cubicle. The findings revealed that a ventilation configuration consisting of 9 h-1 air changes per hour (ACH), three ceiling supply air diffusers measuring 0.36 m2, and six nearby exhaust units measuring 0.04 m2, with a 30% exhaust flow rate of the supply air at a height of 0.8 m, effectively lower the infection risk.
