Reserch On Architectural Cavity Design Based On Indoor Thermal Environment Enhancement

Nowadays,the demands of energy conservation and sustainable development are higher and more,eco-architectural design is more and more concerned by architects.At present,the focus of urban construction in China has gradually shifted to large public buildings,whose functions are increasingly integrated and complicated,and space is becoming increasingly giant.Because of the excessive dependence on technology,indifference to the environment of the city,the idea of architectural design and the old management concept,etc.,people have led to the neglect of the use of green energy to varying degrees.The concept of architectural cavity is born with more and more attention to eco-architectural design.Based on the theory of morphological occurrence and bio-climatic buffering,this paper summarizes the experience of building and nature in collaborative development from history and natural experience.Based on the study of the relationship between indoor thermal environment and human comfort and natural climatic factors,this paper studies the exchange of energy and material flow in architecture and surroundings,and explores the improvement of architectural cavity for indoor thermal environment.In this paper,the architectural cavity is classified as the architectural level.The architectural cavity of the architectural entity's level is wedge into the building with the space blocks such as patios,dooryard,so that the architecture and nature coexist harmoniously.The building cavity of Architectural details' level can achieve the ecological construction with a more functional space block,including ventilation tube wells,double skin,ventilation floor and other forms to help the building's thermal environment regulation in a small range.The last chapter of this paper uses the conclusions of the previous three chapters to make a quantitative analysis of the relationship between the cavity and the indoor thermal environment by changing the various variables of the cavity form to form a new model,then using the simulation software of building environment to simulate the thermal environment.Finally,the actual project case is optimized by the cavity placement,and the optimization results are judged by the simulation analysis to achieve the combination of theory and practice.
