Tessellation-based Designs For Facades To Optimize Daylight And Thermal Performance

China’s rural residential construction has a large amount and a wide area,but due to the constraints of economic,technical and other factors,it has been in the stage of rough design and construction,with high energy consumption and low thermal comfort.The climate in Jingbian area is cold and long,and the heating energy consumption of rural houses is more prominent.How to make full use of natural resources and adopt design strategies to reduce heating energy consumption under the premise of improving the indoor comfort of rural residential buildings is an urgent problem to be solved in rural residential buildings in Jingbian area.At present,the research on indoor solar thermal environment of rural residence is in the developing stage,and the research on rural residence in solar energy rich area is even less.This research can enrich the theoretical research on solar thermal performance optimization of rural residence in solar energy rich area.In view of the actual problems of rural housing in Jingbian area,this paper makes a systematic research on its thermal environment,natural lighting environment and heating energy consumption in winter.The research is divided into two levels: questionnaire survey and field test.Through the questionnaire survey,the basic situation of rural housing,heating energy consumption and thermal environment comfort,natural lighting environment comfort are mastered.Through the field test,the typical rural housing temperature,natural lighting illumination and other physical environment parameters are collected.This paper analyzes the rural residence from two aspects of thermal environment and natural lighting environment,and finds that the overall thermal performance of rural residence is poor,the heating energy consumption is high,the thermal comfort is low,and the rural residence window needs to be designed with light and heat coupling.Based on the actual project of the author’s participation--the design of small residence in Yangguang village of Jingbian County,this paper explores the optimization of light and heat environment comfort and heating energy consumption of rural residence in Jingbian area.This study is divided into three parts,the first is to carry out field investigation on the project land,and reasonably analyze and sort out the surrounding environment of the project.The design difficulties of this residential project are clarified,and the feasibility of the scheme is explored.The second part of the building layout mode of single objective optimization,explore the different attributes of the function block in which layout form,can maximize the use of solar radiation in winter,improve the indoor thermal environment comfort.The third part is on the basis of the previous selection of layout mode,select the appropriate window and sunshade component parameters and variable control,as well as the setting of optimization objectives,and finally complete the optimization of the residential building’s thermal performance.Through the above process of Jingbian rural residential thermal environment,natural lighting environment and heating energy consumption optimization simulation,compared with the results before and after optimization,we can clearly see the differences in the performance of the residential,so as to verify the effectiveness of the design strategy.Based on the multi-objective optimization of solar heating performance and solar thermal performance,the feasibility of multi-objective optimization of solar heating performance is proposed Rural housing in the city.
