HVAC engineers are frequently challenged to design centralized air distribution systems with a high standard of performance considering comfort, energy efficiency, and indoor environmental quality. However, conventional design processes of centralized air distribution systems rely on rules of thumb and engineers’ experience, resulting in workable designs but not necessarily optimal in terms of performance and cost. One major challenge of this design problem is optimally designing the ductwork of a centralized air distribution system. To overcome the ductwork design-associated challenges, a simulation-based method can be an effective tool to achieve optimal ductwork design and performance. The foundation for such a framework has been laid in previous research developing a ductwork design optimization algorithm. This algorithm provides a groundwork method to design ductwork systems while minimizing their life-cycle costs.Nevertheless, this optimization method and the other existing design methods are limited to generating ductwork design configurations by only considering the aeraulic performance of the ductwork system. Despite the fact that the acoustic and aeraulic performances are correlated, the acoustic performance assessment and designing silencers still do not receive enough attention while designing the ductwork configuration (i.e., layout and sizes). They are typically considered after deciding on the ductwork configuration design. Yet, considering the diversity of the...
