Abstract
The wind energy resources of high-rise buildings have been increasingly becoming one of the most important sources for achieving zero-carbon buildings and cities. However, due to the lack of understanding regarding the relationship between the wind energy potential and the complex geometries of the central business district (CBD), the developments of wind energy utilizations were severely limited. Employing validated CFD simulations, this research has studied the core skyscraper representatives of the Lujiazui CBD in Shanghai to reveal the correlations between the aforementioned complex geometries and key indicators of wind energy resources. The potential locations of wind turbine installations hadd been analyzed in detail. It has been found that to achieve higher wind power potentials, the representative floor planes should opt for rounded or smoothly chamfered shapes rather than sharp-edged polygons or rectangles. Besides, the roof profile should favor conical and semi-circular shapes over a flat roof, and the outer edges of extended planes are more suitable for installing wind turbines. For twin skyscrapers, the excessive angles between internal clamping channels and the prevailing wind directions should be avoided. The results can provide scientific and practical references for the optimizations of complex forms of skyscrapers in urban CBD blocks.
