Modeling and Simulation of windows with noise mitigation and natural ventilation

Noise is one of the most important factors which determine the liveability in urban areas. It is common that buildings will be exposed to higher ambient noise level generated by various noise sources, as we intensify the land use. In a high-rise high density living countries like Singapore, the building envelop often constitutes to the primary path for external noise sources to travel into the living environment. Therefore it is desirable to develop windows which can address the issue of high noise levels while maintaining natural ventilation. It is both challenging to design and evaluate the window performance. Here we present the numerical approach to analyze such window designs; in particular, the numerical models and simulation results to evaluate the window transmission loss and ventilation, and then the optimization window design results. This gives the basis for further developing windows, with addition of smart materials and active control elements.
