Research On The Design Of Carbon Absorption Building Based On Carbon Balance Theory

With the development of human civilization,the global carbon emissions have reached the critical value of endangered,and all countries have responded to the call to launch the action of energy conservation and emission reduction.At present,scientists have conducted in-depth research on the types of carbon sinks on the earth,and found a new way to capture carbon dioxide in the atmosphere,"building carbon absorption".It has been proved that the carbon absorption capacity of buildings mainly comes from the capture and fixation of carbon dioxide in the atmosphere during the carbonation of concrete.With the increase of population and the increase of construction volume,the carbon absorption capacity of buildings in our country is also increasing,the total amount is very considerable,but the research and exploration of this capacity is less.Therefore,based on the basic theory of carbon balance,taking concrete building as the main research object,this paper makes an in-depth study and Analysis on the influencing factors of building carbon absorption and the design method of carbon absorption building.In this paper,starting from the principle of concrete carbonation,from the perspective of materials,environment,time and chemistry,the influence mechanism of concrete carbonation is studied and analyzed,and then the influencing factors of concrete carbonation are summarized,and how these influencing factors affect the carbon absorption capacity of buildings further through the influence of concrete carbonation is obtained.Secondly,from the perspective of architectural design,explore the relationship between architectural design and building carbon absorption capacity,refine the influencing factors,and select the material factors that are too large under the influence,and the human factors that are more controllable,and the heat and humidity factors in the environment to guide the architectural design,and then summarize a set of modular architectural design methods guided by carbon absorption and combined with assembly building,Starting from different stages of architectural design,through the carbon absorption influencing factors to guide the architectural design on the premise of meeting the building function.Then the paper uses the carbon absorption architectural design method to carry on the empirical research,selects the small public building as the research object,carries on the design research from the building plane layout,the structural form,the enclosure structure,the architectural form and so on,and has made the appraisal to the carbon absorption capacity of the building.
