Acoustic performance, natural ventilation, energy efficiencyAbstract
The windows can be passive ventilation control elements and also sound attenuation. This article aims to present a summary of the existing literature and evaluate the performance of these elements. This review shows that such windows are essential in the construction of contemporary cities, as they combat prolonged exposure to high levels of external noise, while enabling natural ventilation. Thus, they are bioclimatic methods that enable energy efficiency for construction, since they avoid the use of mechanical ventilation. According to this research, it is concluded that the use of elements such as resonators or refractors in windows can significantly reduce external noise, however there is a considerable loss in natural ventilation. The use of deflectors and blinds on the window or the presence of balconies with absorbers or reflectors are not effective elements in attenuating noise, which may also contribute to noise pollution in the city with the reverberation of sound. Finally, plenum windows, which are devices with staggered air inlet and outlet, are the most advantageous alternative at the moment, in noise attenuation and permeability for ventilation.
