Wind energy development is helpful for a sustainable city. This work is concentrating on the estimation urban wind energy with urban morphology study. Fourteen typical urban forms in Beijing city were selected and analyzed with nine relevant urban morphology parameters. CFD numerical simulations were used to evaluate the wind energy potential of the urban forms. This work found that the urban forms with high plot ratio, high mean aspect ratio, high relative rugosity or high standard deviation of the building heights, usually have high wind potential density by site area, which is important for community-scale wind potential development. Urban forms with high standard deviation of the building heights, usually have high wind potential density by roof area, which is important indicator for building-scale wind potential development. In order to promote wind potential over roof, a layout of 45° on building configuration and round-angle-in-exterior-wall building forms are suggested.
