Research On Design Of Outdoor Space In Residential Areas Orientated By Suitable Wind Environmentin Guangzhou

Residential area is an important carrier of residential life,a good outdoor environment is conducive to improving the residents’ intention of outdoor social activities,increasing the vitality of residential areas.At the same time,a good wind environment helps to speed up the efficiency of air purification in residential area,reducing the radiation temperature of hot summer,weaken the local heat island effect to a certain extent,which has a positive significance in enhance the comfort of the living environment.This paper first analyzes the relationship between outdoor space and wind environment in residential area,and puts forward the necessity and analysis direction of suitable design of outdoor space wind environment in a residential area.Based on the research of meteorological data and the related experimental study of Guangzhou area,reflecting the Guangzhou region climate is warm in winter and hot in summer,summer heat and humidity,wind field near weak,urban area near no wind area more wind environment present situation characteristic;Then,based on the wind environment in Guangzhou region characteristic,analyzed a variety of existing wind environment comfort evaluation system,comprehensive,based on the thermal comfort evaluation system in the divisions of wind comfort level((V<1m/s range,three lag wind,poor rating,low wind speed range is defined as not comfortable)and a quantitative model of static wind the area ratio of the proposed uncomfortable wind speed range(V<1m/s)for the static wind zone measure static wind area than quantitative analysis is suitable for the unique wind environment conditions in Guangzhou area.At the same time,combined with the enclosed space field theory,comparative analysis the relationship between typical morphology and outdoor activity space of the residential area of Guangzhou,conclude the five basic forms of unit area outdoor living space in Guangzhou area: one-way closed space unit,more open space unit,shaft type space unit,semi closed space unit and fully enclosed space unit;and the simulation analysis of the above five categories of outdoor space unit were simulated and analyzed respectively the basic form of wind environment,proposed a series of measures to change the windward angle,surface drainage,morphology,frame empty import and export under the guidelines,the wind environment design optimization of the corresponding types of space form unit,provide reference and direction for the construction in good wind environment in outdoor space of the residential project in Guangzhou area.In addition,through the analysis of various reference factors planning and design of residential areas,found that the preliminary design plan of residential area depends on the decisive factor of itself,wind environment is not a decisive factor,premise of wind environment design optimization should be carry on under the premise of ensure land and maintain the original residential design ideas;at the same time,analysis of the characteristics of each stage of planning and design process,proposed wind environment design concept should be the beginning of the project planning intervention throughout the project always,in determining the preliminary project,using CFD technology combined with the guidance of wind environment design of five kinds of basic spatial unit in Guangzhou area based on the preliminary scheme of wind environment suitability optimization the final design scheme can not only satisfy the original design ideas,but also establish the comfortable wind environment.Based on the current trend of city environment is gradually gets more attention,In this paper,through the research and analysis of the residential outdoor space in Guangzhou region,the establishment of appropriate methods for planning and design of wind environment under the guidance of,can enrich the residential outdoor space design theory,has a certain theoretical significance;this out to create a good outdoor space in residential area the wind environment suitability design strategies and guidelines,can contribute to the promotion of residential outdoor recreation area attractive outdoor space design to provide more possibilities of ecological environment quality of living.Establish suitable auxiliary Plan and design methods under the guide of suitable wind environment,which can enrich design theory of the residential outdoor space,has a certain theoretical significance;propose the design policies and guidelines to create a good residential outdoor wind environment,which can promote the attractiveness of residential outdoor recreation area,provide more possibilities to optimize the design of the ecological environment in residential area outdoor space.
