The study of ventilation windows for both natural ventilation and noise mitigation uses has drawn attention recently. It is challenging to design and evaluate the window performance by means of modelling and simulation. Here we present the numerical approaches to analyse and predict the thermal and acoustical performances of different window designs. By assuming typical flow and temperature conditions, the distribution of air velocity and temperature field in a representative residential unit is calculated using Computational Fluid Dynamics (CFD) method. The thermal comfort is evaluated using a static model based on the Predicted Mean Vote (PMV) method. As for the acoustic performance, the Sound Reduction Index (SRI) is studied by a proposed Finite Element Method (FEM) model, which is compliant with the ISO measurement standard in laboratory. Using the combined approaches, parametric studies are carried out based on a double-layer ventilation window configuration, where the effect of window opening sizes and the inlet flow conditions are investigated. It is found that the window design can provide enough fresh air, maintain adequate thermal and acoustical comfort by properly choosing the opening size. The feasibility of using a computational platform to evaluate and optimize ventilation windows is shown.
