Abstract

Global origination "High Performance" Sustainable building used Wind Turbine Generators ---Pearl River Tower will produce bigger environmental noise when the wind blows through the tunnels of the building and Wind Turbine Generators. In order to prevent the noise to much effect on the nearby office staff and residents and affect the reputation and the performance of the Pearl River Tower, It is necessary to predict and evaluate the noise level and distribution emitted by the Pearl River Tower. broadband noise source model based on the SST turbulence model was used to numerical simulate the noise level and distribution of the tunnels of the Pearl River Tower and Wind Turbine Generators, then influence of Wind Turbine Generators on noise of the Pearl River Tower was analyzed. The numerical simulation results show that under one year return period or maximum monthly mean wind speed, the maximum noise of the Pearl River Tower doesn’t exceed the limits set by the “Law of the People's Republic of China on Prevention and Control of Pollution From Environmental Noise”.

Key words
