The Current Status of Natural Ventilation- Enabling Noise Reduction Devices in Urban Green Buildings

摘要

In the process of urbanization, in order to reduce energy consumption and improve indoor environmental quality, natural ventilation system is widely used in many green buildings. But under the interference of noise pollution, it is difficult to balance the relationship between ventilation and denoise. This paper summarizes the current status of natural ventilation- enabling noise reduction devices in urban green buildings, and focuses on the sound insulation properties of windows, balconies and ventilation pipes. Compared with traffic administration, green belts and noise barriers, the devices are easier to implement and have higher cost-effective. Furthermore, this paper also analyzes the drawbacks of existing and the development prospects of the devices.
