The performance of small wind power generation systems on super high-rise buildings

This study was conducted on the application of small wind power generation systems to super high-rise buildings. Environmental factors considered in the application of small wind power generation systems to super high-rise buildings are the wind speed, wind direction, maximum instantaneous wind speed, air flow turbulence, and noise and vibration in the target regions and buildings. According to the results of fluid dynamics (CFD) simulations, square or rectangular shaped super high-rise buildings create turbulent air flows occurred uniformly on roofs and the sides of entire buildings, from the lowest floor to the highest. High wind speeds occurred on the sides of buildings. Few turbulent beds occurred in the case of round or triangular shaped super high-rise buildings indicating that round and triangular shapes in plan are advantageous for the application of wind power systems. Electric power generation was measured in mock-up tests. When they were installed in a row, small wind power generation systems met the standards for noise and vibration from continuous rotation indicating that they would cause little damage to buildings through their noise and vibration.
