Study on the Influence of Spatial Morphology of Teaching Buildings on Outdoor Wind Environment:A Case Study of Handan University in Hebei Province
Research and analysis of four universities in Handan,33 academic buildings,summarized four types of courtyard layout forms,nine kinds of space morphology,fitted out the first floor area and courtyard space area of the functional relationship,the establishment of seven groups of test combinations.The study shows that the comfortable wind area ratio of three-sided enclosure(east and west),two-sided enclosure(northeast and northwest),juxtaposition(east and west),and four-sided enclosure(single courtyard)is between 92%and 95%,which can create a better outdoor space;the analysis of the comfortable wind speed ratio of the corner point and center point of the courtyard space shows that the wind speed ratio of the juxtaposition(east and west)in the corner point and the center point is within the limit,and there is a good wind environment;with the increase of the first floor area,the similar courtyard space area and the first floor area increase,and the similar courtyard space area increases,area increases,the wind resistance index of similar courtyard forms decreases,the better the ventilation efficiency.When the area of the first floor is 3000m2,the wind resistance index of four-sided enclosure(double courtyard)is the largest,and the ventilation effect is the worst,so the design should avoid this kind of layout.Under the same area of the first floor,the wind resistance index of two-sided enclosure(northwest courtyard)is the smallest,which is more conducive to the demand of outdoor wind environment.
