Research On Optimization Design Of Thermal Comfort Of Rural Homes For The Elderly In Rizhao Area

At present,China is entering an accelerated period of aging,and the elderly population in rural areas is increasing rapidly,it is obviously urgent to solve the problem of living comfort for the elderly in rural areas,which is a common challenge for the relevant personnel in our construction field.The rural old-age care in China is generally home-based care.However,at this stage,we have not considered enough the special thermal comfort needs of the elderly in rural areas.The lack of suitability and comfort of residential buildings for the rural elderly has been neglected for a long time,which has affected the health and life of the elder people.At present,the relevant domestic building codes and standards have not yet clearly put forward the design indexes and relevant parameters suitable for the residential thermal comfort needs of the elderly in rural areas.With the social improvement of the living standards of the elderly residents in the countryside,higher requirements are also put forward to the comfort of living.Therefore,it is particularly urgent to improve the living standard of rural elderly residents,especially to optimize the thermal comfort of rural elder.Under this background,this paper investigate the thermal comfort optimization design of rural dwelling houses for the aged in Rizhao area.Literature on indoor thermal comfort and elderly thermal comfort in domestic and foreign residences were combed.The factors that affect the thermal comfort of rural residential care homes in Rizhao area were analyzed.Through visits and investigations,the thermal environment parameter test and questionnaire survey for the elderly were completed to understand the current situation of rural residential care for the aged in Rizhao area and the existing problems in indoor thermal environment,the subjective feelings and votes of the elderly were statistically analyzed.Based on the combine analysis of qualitative and quantitative,the range of thermal environment parameters to meet the residential thermal comfort needs of the local elderly was obtained,and the optimal design strategy for thermal comfort of rural residential care houses in Rizhao area was proposed.Finally,Design Builder simulation software was used to verify the optimization strategy.The full text consists of six chapters:The first chapter is the introduction.This paper about the research background,research status at home and abroad,research purpose and significance,and research contents and methods in turn.The second chapter summarizes and analyzes the influencing factors of thermal comfort of rural residential care homes in Rizhao area.Including natural climate characteristics and living cultural customs,natural and behavioral characteristics of the elderly,as well as indoor thermal environment factors and human factors.The third chapter makes an on-the-spot investigation on the current situation of rural residential care for the aged in Rizhao area.The subjective questionnaires of the elderly were collected and the thermal environment of the residence was measured with professional instruments.After a preliminary analysis of the above survey data,two typical rural residential homes for the aged in Rizhao area were selected to continuously measure their indoor and outdoor thermal environment parameters for a long time in summer and winter respectively.In the fourth chapter,based on the previous basic theory and field investigation,according to the relevant domestic design standards and existing research,and referring to the calculation results of subjective thermal comfort temperature index,the thermal environment parameter range that meets the thermal comfort requirements of the local elderly was obtained.From the two main aspects of building scheme and enclosure structure,this paper puts forward the optimal design strategy for thermal comfort of rural residential care homes in Rizhao area.In the fifth chapter,a typical rural residential model in Rizhao area was selected and simulated by using Design Builder software.By comparing and analyzing the simulation results of the optimization scheme,the effectiveness of the optimization design strategy is verified.The sixth chapter summarizes all the research contents of the thesis and points out the deficiencies in the research process.This paper combines the thermal comfort theory of the elder with the research on the optimal design of rural housing,aiming at improving the residential comfort of the elderly in rural areas.It is hoped that this research work can provide reference for the theory and design practice in related fields in the future.
