A Study On The Design Of Summer Microclimate Adaptability Of Public Squares In Hot Summer And Cold Winter Areas Based On Numerical Simulation

The phenomenon of global warming and the urban heat island effect have made it more and more difficult for the urban climate environment to ensure the comfortable living environment of residents.It's positive for landscape planning and design personnel through the design and deployment of various environmental resources to create a comfortable human space environment from the professional perspective of space.Citizen square is the research object of microclimate adaptability design in this paper.In order to improve the scientific nature of landscape architecture design strategy,this paper takes Hefei area as the representative to study the guidelines and methods of summer microclimate adaptation design of citizen square in hot summer and cold winter area based on numerical simulation.Firstly,the paper studies the theoretical system of microclimate adaptation design of public square in hot summer and cold winter area.The research contents include: Determination of thermal discomfort time threshold in hefei area;The establishment of the evaluation system for the design of micro-climate adaptability of civic square;The establishment of the design target system of micro-climate adaptability of the public squares in hot summer and cold winter areas.The study of the theoretical system lays a solid theoretical foundation for the following research on the design methods and design examples of microclimate adaptation.Then,in the study of design method of microclimate adaptability of Citizen Square based on numerical simulation.For the two design scenarios(multi-scheme optimization and scheme optimization)in the microclimate adaptation design,the detailed and complete research and summary of the microclimate adaptation design flow method based on numerical simulation was carried out.The simulation tool(Envi-met)most suitable for the design and study of micro-climate adaptability of public square was selected after research and analysis.These results can be used to guide the example design below.Finally,the application of practical cases verified the effectiveness of the above research results of the theory and method of microclimate adaptive design in hot summer and cold winter areas.The conclusions of this paper include the specific process of microclimate adaptation assist design of the numerical simulation software is applied to multiple scheme optimization design cases and scheme optimization design cases,scheme evaluation criteria and the design strategy of summer microclimate adaptability of public square in hot summer and cold winter area is obtained by combining theory with case study.These results provide practical experience and ideas for design research in related fields.Based on the time limitation of the thesis research,the number and scope of the case of the square can be expanded in the future,as well as more in-depth study of the design scene.
