초고층 건물의 풍력발전시스템 적용방안에 관한 연구

Abstract

The research was conducted for the application of wind generator systems in high-rise buildings, and drew out elements to consider for the application of wind generation in high-rise buildings, especially, by providing a design process for application to high-rise buildings. Also, basic data for applying the wind generation system in high-rise buildings has been provided by case analysis and CFD simulation. The research results are summarized as follows;In an urban wind environment, the volatility of wind speeds become more severe as it gets closer to the surface of the earth,but because wind speeds become stronger with the rise in altitude, applying a wind generation system to a high-rise building is possible, even in an urban setting. That is, the average wind speeds on 200m high-rise buildings were 5.7~7.4m/s, while they were 6.6~8.0m/s on 500m buildings. Among the many methods of applying wind generation to high-rise buildings, installation on the highest floor or to the side of buildings presented most advantageous in Korea because the average wind direction changes from season to season. In the simulation following the wind generation application process (72 floor mixed-use high-rise residential building), high wind speeds were able to be secured due to the high elevation of the building, and installation to both the roof section of the highest floor and parts of the side were feasible. In particular, the installed wind generation system was able to sufficiently cover a part of the total energy consumption of the high-rise building.
