Analysis And Optimization Of Light Environment Of Residential Space In Changsha Pension Building

With the intensification of China’s aging population and the gradual increase in the demand for old-age care in institutions,the indoor light environment design of old-age buildings has been unable to meet the higher requirements of suitable aging needs.At the same time,Changsha city has many rainy weather in winter,and outdoor activities of the elderly are greatly restricted.As the main activity place of the elderly in the retirement building,the light environment of the living room is particularly important for the physical and mental health of the elderly.According to the research status at home and abroad,the author found the following points: In the past,the research on the light environment of the old-fashioned building room space only considered the natural lighting environment during the day and the artificial lighting environment at night,and ignored the natural lighting conditions at dusk.When it is not good,the comprehensive light environment research after the combination of the two;lack of systematic research on the current situation and data testing of the residential space of Changsha’s old-age buildings;lack of the light environment of the old-age buildings that meet the aging requirements and meet the relevant standards and specifications Comprehensive design strategy research.Based on the above problems,the research is divided into three parts,with a total of five chapters:The first part is the introduction of the first chapter.According to the research background of this article,the purpose and significance of the research are proposed,and the corresponding research methods are formulated.The second part contains the second,third,fourth and fifth chapters,which is the main research content of this article.The second chapter summarizes the psychological and physiological characteristics of the elderly,and focuses on the special needs of Alzheimer’s patients for the light environment.Improve and summarize the light environment design standards of the old-fashioned building room space.The third chapter mainly investigates the objective current situation of the light environment of the sample buildings of the old-age buildings within the scope of Changsha City.The data of the natural lighting environment and the artificial lighting environment are tested respectively.The objective evaluation of the measured data is made according to thestandard and the light is found.Problems in the environment.The fourth chapter extracts the typical living space of the old-age building,uses the simulation software DIALux to simulate the design factors related to the natural lighting and artificial lighting environment,and summarizes the specific light environment design strategy.On this basis,it was creatively proposed to use an intelligent control system at dusk to control the lighting output rate of lighting equipment to improve the current situation of insufficient indoor illumination due to insufficient natural light,which is a problem for Alzheimer’s patients.Treatment and relief provide new ideas.The fifth chapter mainly applies the light environment design standards and light environment comprehensive design strategies studied above to practical application,and guides the specific sample room optimization design with the research results,and verifies the operability and practicability of the comprehensive design strategy.The third part is the conclusion,summing up the research results,analyzing the innovations of this article,and reflecting on the shortcomings of the research.The author hopes that through the research in this article,it can provide some help for the research on the light environment design and optimization of the residential space of the old-age buildings in Changsha,improve the comfort of the light environment for the elderly,and make some contributions to the society.
