Research on the Current Characteristics of Roof Wind Energy based on the Spatial Form of Urban Areas:Taking the Commercial District Building of Xinhua Street in Hohhot as an Example
The global environmental pollution and energy crisis have made renewable energy widely concerned.Wind power generation,as the development and utilization of wind energy,has attracted the attention of all countries in the world.The complex building wind environment in the urban area makes the wind energy resources of the building roof not fully utilized.Therefore,this paper takes the super high-rise office buildings in several commercial areas of Xinhua street in Hohhot city,Inner Mongolia autonomous region as an example,carries out a statistical analysis of the representative spatial form units in the area,and makes a numerical simulation of the current situation of roof wind energy in the unit.It is found that the spatial characteristics of urban areas will significantly affect the wind environment of building roofs.The wind speed in areas with high plot ratio,low openness:changes little with the height,while that in areas with low plot ratio and high openness increases significantly with the height.Wind energy resources in high-density area increase significantly after reaching 90 m height.Meanwhile,this paper can provide referential technical methods and data support for the research on wind energy utilization in urban building rooftops,thereby facilitating the effective utilization of wind power generation on building rooftops.
