Study On Lighting And Thermal Design Of Green Residential Envelope In Dalian Area

Since the beginning of the 21 st century,The earth’s climate and environment are deteriorating gradually,and extreme weather phenomena such as haze and typhoon are increasing gradually.With the goal of saving natural resources and energy conservation and environmental protection,achieving substantial sustainable development has gradually become the common concept of all countries.In all human construction activities,residential building construction is the most fundamental demand of human activities,occupying a large proportion and an important position..Green residential innovative housing model,energy-saving and environmental protection of natural resources and advanced technology used in the building process,play the guiding role of sustainable development strategy,so that residential consumption of resources and pollution of the natural environment to a minimum.Green residence emphasizes the saving and utilization of resources and energy,at the same time,it realizes the harmonious coexistence of residential area and environment..In the design of residential buildings,the energy consumption of enclosure structure occupies a large proportion.The lighting and thermal design of green residential enclosure structure does not consume or consume little energy,and there is no waste and pollutants.Therefore,the good lighting and thermal design outside the enclosure structure not only improves the living comfort,but also improves the quality of living environment.Thermal and lighting design of residential envelope structure is a green and environmental protection technical measure.Reasonable application design will promote the construction and development of green residence.Based on the relationship between total daylighting and thermal design of envelope structure of green house and evaluation criteria of green building,this paper expounds the significance of research on daylighting and thermal design of envelope structure of green house.Through the evolution and analysis of standard values,the characteristics of daylighting and thermal design of envelope structure are excavated.Secondly,from the aspects of sunshine design,daylighting design,envelope structure performance and materials,the problems of daylighting and thermal design and unification of green building envelope structure are analyzed in detail.The synthesis of daylighting and thermal design is discussed by comparing standard indexes,material performance indexes and the use of software.The method of sex analysis provides a good way for subsequent engineering case analysis.Combining with specific cases,by using sunshine analysis software SUN2016,daylighting analysis software DALI2016 and energy-saving design software BECS,andcombining with practical cases,the lighting and thermal design of envelope structure of green residential buildings in Dalian area are simulated and analyzed,and the lighting and thermal design of high-rise and multi-storey residential buildings are compared.Through setting sunshine parameters,window type,window size,heat transfer index of window,exterior wall masonry material and other parameters,the lighting and thermal performance of the envelope structure are quantitatively analyzed and compared through the results.Finally,the paper puts forward reasonable suggestions and optimization design strategies for daylighting and thermal design of residential envelope structure in Dalian area,which has positive practical significance for future residential design in Dalian area and has reference value for follow-up research.
