Research On The Form Optimization Design Of Underground Atrium In Cold Area Based On Climate Adaptability

In the relationship between climate,architecture and people,architecture is an intermediary between man and climate,and plays a crucial regulating role.Building adaptation is divided into active regulation and passive regulation.Active regulation consumes huge energy consumption and resources.In the context of carbon neutralization and carbon peaking,more passive regulation is obviously needed to share the regulation pressure.At present,the passive regulation of above-ground buildings has been extensively studied,while the passive regulation of underground buildings is still in the development stage.As an important spatial node of underground buildings,underground atriums should receive more attention.Therefore,this thesis will carry out a study on the optimal design of the shape of the underground atrium based on climate adaptability,and improve the physical environment quality of the underground atrium through the shape control under the passive control,so as to respond to the climate and achieve the purpose of reducing energy consumption and increasing building comfort.This thesis firstly defines the concepts of the shape and climate adaptability of the underground atrium,analyzes the climatic characteristics of the cold region,extracts its climate factors,and responds to the climate with the light and heat environment,extracts the influence factors of the light and heat environment of the underground atrium and the shape factor of the underground atrium,The shape design parameter system of underground atrium is constructed according to the classification of shape factors.Secondly,the Ladybug+Honeybee software is used to build a parametric underground atrium performance simulation method.By controlling the shape design parameters of the underground atrium,it simulates the light and thermal performance of the underground atrium under non-air-conditioned conditions,and explores the effect of each shape parameter on the light and heat environment of the underground atrium.relation.Then,using Ladybug+Honeybee+Wallacei software,a multi-objective optimization method of underground atrium shape under non-air-conditioning state oriented by the differentiation of light and thermal performance is constructed to explore the shape of underground atrium suitable for cold areas.Finally,taking Suning Plaza as an example,comprehensively considering the construction factors that need to be considered in the actual architectural design,such as the use function,economy,surrounding environment and construction difficulty of the building,the design and application of the underground atrium in cold areas is carried out for the design of underground atriums in cold areas.refer to.The main results of this thesis are as follows:According to the orientation factor,body factor,interface factor and volume factor of the shape of the underground atrium,the shape design parameter system of the underground atrium is constructed.The parametric light and thermal performance simulation method of the underground atrium is constructed,and the relationship between each shape parameter and the light and heat environment of the underground atrium is respectively explored.A multi-objective optimization method for the shape of the underground atrium oriented by the differentiation of light and thermal performance was constructed,and several design parameters of the shape of the underground atrium suitable for cold areas were obtained.Through the design and application of the underground atrium of Suning Plaza,the feasibility analysis and application of the shape design parameters of the underground atrium adapted to the cold area are carried out.
