Abstract

With the accelerated process of urbanization and the rapid development of science and technology, a large number of high-rise and high-rise residential rise. The expansion of the high-level settlements area, floor area ratio continued to increase, triggering a series of wind environmental problems, such as safety, comfort, and energy saving. These issues and settlements layout, residential building size, surrounding buildings, wind direction, and afforestation has a complex relationship, if we can accurately predict the wind environment, explore the inherent law of the improvement of people's living environment will have a very important significance. Urban residential area wind environment conditions directly affect the daily life of residents and residential building energy consumption, such as the winter cold northern regions reasonable form of residential heating can reduce energy consumption. These problems both at home and abroad have been increasing attention has been paid. Many developed countries have legislative requirements in the design stage of the building, given the environmental impact assessment of the buildings built after the wind. This paper analyzes the characteristics of the environment in cold rise Residential wind partition from the climate, the high-level settlements the microclimate characteristics as well as the wind environment relative comfort evaluation criteria to start to study the design method for high-level the Settlements wind environment in cold and established The use of wind speed ratio as the evaluation criteria. On the basis of previous research experience, mainly by senior settlements in cold winter winds to explore. First, the establishment of the model definition of the object of study and solving methods; Then, settlements in various types of flat-screen combination (point, plate, plate point binding type) the adjacent residential height residential pitch change under the conditions of row height wind environmental analysis, summarize some of the qualitative and quantitative impact of the law. Finally, the senior settlements in cold wind environmental design strategies, and Harbin, a senior settlements overall simulation analysis for simulation results to adjust the layout of it better outdoor wind environment. This paper uses a simulation, compare, summarize, pressure, wind speed ratio of wind environmental data analysis methods on the model object definitions and calculations, and their comparative analysis, summed up the impact of wind environment Comfort icon and data as the basis of design strategy proposed the senior settlements in cold wind environment. Designed to provide comfort for cold regions rise Residential Wind environmental planning, energy saving design basis and design strategies to quantify.
