Severe cold area building courtyard optimization method based on winter wind environment simulation

Abstract

The invention provides a severe cold area building courtyard optimization method based on winter wind environment simulation. The method concretely comprises the following steps that 1, reference physical models of a courtyard and a peripheral space are built; 2, the boundary conditions are set according to Special Meteorological Data Set for China Building Thermal Environment Analysis; 3, simulated parameters are selected for simulation analysis; 4, simulation data analysis is carried out, and an optimum design strategy is obtained. The method provided by the invention has the advantages that the regional features of a severe cold area are used as study development premise, and the limitation caused by using wind field as the single standard is avoided; simulation software is selected, and each design condition and simulation parameter are selected on the basis of theory foreshadowing; an integral study simulation framework is established; an effective optimum design method is provided for discussing acting rules between the courtyard micro environment and the courtyard space form under climate conditions of cities in severe cold areas, and the reference data is provided for the relevant study of the special climate conditions in the cities in the severe cold areas.

Description

technical field [0001] The invention belongs to the technical field of architectural design in severe cold regions, and in particular relates to an optimization method for building atriums in severe cold regions based on winter wind environment simulation. Background technique [0002] The atrium space needs to meet the requirements of ventilation in summer and heat preservation in winter to ensure the comfort of users. This feature has become the dominant factor restricting indoor environment and energy consumption due to special geographical conditions. For regions with hot summer and cold winter, the extreme climate conditions in summer make how to use the atrium space to improve the indoor environment in summer and transitional seasons and promote ventilation circulation has become the focus of research. There are related researches on this issue. For severe cold regions, the climate adaptability requirements of the atrium space in winter surpass other requirements and b...

Problems solved by technology

The layout of the atrium space in the building plan can minimize the impact of cold wind, and the relationship between the proportion of the atrium, the cross-sectional form and its ventilation and thermal insulation performance has not yet been supported by clear relevant data.

[0005] In the current research results, there are mainly the following three problems: the research results on different regions are mainly limited to hot summer and cold winter regions, and there is a lack of relevant research on the special climatic conditions of cities in cold regions; in the research on atrium space , most of the atrium space is taken as a separate research object, ignoring the connection between it and the atrium connecting space; in the existing research, there is a lack of atrium environment simulation research led by architectural design
