Research On Shape Of High-rise Building Of The Third And Fourth Units In Qianhai Area Of Shenzhen Based On Wind Environment

Along with the rapid development of urbanization, large population,high-density urban built-up areas have emerged in the city, causing urban climateissues have become increasingly prominent. The climate also has been a key factorthat the impact of the architecture and development, based on climate concept toguide urban development, ensure the positive interaction between architecture andclimate, lay the foundation for the construction of the road of sustainabledevelopment. Subtropical climate zone urban wind environment is recognized as thedominant element of the overall urban environment directly affects the city’scomfort and healthiness. Excellent architectural form layout conducive toimproving the city’s air condition, therefore, from the starting point to improve theurban environment, the wind start research on architectural form has importantsignificance.The third and fourth development units in QianHai area of ShenZhen belong tothe new construction area, the special nature of the land, the high-rise buildingsbecome a major factor to affect the development unit in the wind environment.Through the high-rise building wind environment-related issues in basic research,summed up the impact of high-level wind environment form factor. Accordingmorphological types of high-rise buildings, the unit high-rise buildings areclassified into point-rise buildings, plate-rise buildings, high-rise buildingtownhouse podium. The use of data processing that the year winds estimated inQianHai area of ShenZhen Bureau of Meteorology, the use of CFD simulationtechnology to its three kinds of building types for wind environment simulation test,According evaluation criteria of the wind environmental comfort, evaluation windenvironmental issues that all types of high-rise buildings are mainly caused.Analytical Development Unit within the lot specific wind caused problems derivedform factor high-rise buildings, mainly affected by building orientation,architectural graphic form, massing, building facade composition, street podiumfacade detail. And then simulation each element of the shape and results elementshape that improved the wind on the surrounding environment, and then draw theform that appropriate development unit high-rise building form elements.On the basis of analysis of wind environmental issues in the three types ofhigh-rise buildings, proposed for the development of the overall pattern control unithigh-rise building policies, aside from the main duct, lower ground coverage,increasing the amount of ventilation towers and set up three-dimensional green. For each type of building development unit specific problems, point-rise building toweak strong winds on the corner, distribute the vortex flow under the windward side,plate-rise buildings to reduce wind shadow area, avoid street canyon wind,townhouses podium rise building to strengthen internal ventilation, reducingupwind blocked, Have put forward concrete high-rise building forms controlstrategy.Finally applying the above analysis conclusion, through guidelines prepared ofhigh-rise building shape of the third and fourth development units in QianHai areaof ShenZhen, angle to create a suitable environment for the wind, guide and controlthe high-rise building shape of the third and fourth development units in QianHaiarea of ShenZhen.
