Study On Healthy Retrofitting Of Old Tropical Communities With The Participation Of Microclimate Elements

The rapid development of the city will lead to a series of urban diseases,such as the heat island effect,noise pollution,heat island effect,etc.In addition,these problems will lead to new secondary problems,such as the spread of diseases,bacteria,etc.,which will continue to squeeze the health of the inhabitants of the living space.Many elements of the microclimate become determinants of health,such as solar radiation,ventilation,high temperatures,and various potential factors that affect the activities of the population to some extent,in addition to a series of problems brought about by the unique tropics that make the original problems more intense,such as the high density of human habitation that leads to slow diffusion of pollutants and respiratory diseases,high solar radiation during the day,and indirectly reduced activity of the population,leading to obesity and depression.The high solar radiation temperature during the day reduces the indirect activities of the residents,leading to a series of problems such as obesity and depression,in addition to mosquito infestation and humidity,which also affect human health problems.In this context,based on the concept and value principle of microclimate element participation,this paper focuses on the optimization path based on the spatial types and characteristics of tropical cities from macroscopic as well as microscopic perspectives to update the optimization path through microenvironmental simulation analysis,parametric data,low-tech landscape means combined with residents’ environment-behavior study to optimize the residential environment.This study aims to enhance the role of the living environment in promoting healthiness and to provide a reference for the quality development of old settlements in tropical cities in China.At the theoretical level,the conceptual framework of "microclimate healthification" is proposed as the basic theory for subsequent research.The study firstly compares the influencing factors of microclimate and then analyzes how microclimate and residents’ health are regulated and improved through the medium of landscape.At the same time,the feasibility of the study of "microclimate healthification" is explored in depth by incorporating multiple variables,including environmental microclimate,landscape configuration,and activity willingness,revealing the influence weights of multiple latent variables among outdoor space,activists,microclimate,and healthification,and realizing the subjective evaluation of "microclimate healthification".The subjective evaluation and objective quantitative analysis included in "microclimate healthification" build the overall research basis of this paper and provide a solid foundation for the subsequent technical route.In terms of urban design guidance,this paper proposes a design strategy based on the concept of "microclimate health" that applies to old tropical communities.Under the guidance of design objectives,we first propose "vitality prediction" to compare the spatial layout and path guidance of old communities with multiple scenarios of vitality to activate the gray spaces and blocked streets in the city.At the same time,the microclimate simulation software is used to make multiple iterations to calculate the overall renewal pulse: control and optimize the neighborhood morphology,substrate greening,and building interface morphology restoration,to effectively regulate the microclimate health.
