Design And Implementation Of Carbon Emission Calculation System For Building Materials

As global warming is caused by the intensification of greenhouse gas emissions,reducing greenhouse gas emissions,mainly carbon dioxide,is an effective way to control global warming.As the world’s largest carbon emitter,China’s construction industry accounts for a relatively high share of the country’s carbon emissions.Therefore,it is particularly important for the construction industry to achieve energy conservation and emission reduction.The development of the construction industry cannot be separated from the use of a large number of building materials,so reducing the carbon emissions of building materials is of great significance for the realization of the double carbon target.Through research and analysis of the current mainstream carbon emission assessment software systems,it is found that most of the existing software systems evaluate the environmental impact of carbon emissions through energy consumption simulation,but there is a lack of carbon emission calculation system for the recycling and replacement of building materials.Therefore,this thesis combines the whole life cycle theory and uses the SOA architecture with low coupling coarse-grained characteristics from the perspective of energy conservation and emission reduction.A carbon emission calculation system for building materials for specific engineering projects is designed,which can calculate the carbon emission of building materials in the whole life cycle.The feature of this system is that the carbon emission change of building materials recycling and material replacement in the construction process is included in the carbon emission calculation results of the whole life cycle.On this basis,suggestions on energy conservation and emission reduction are given according to the actual situation of the project.The carbon emission calculation system of building materials consists of four main modules:information input module,building material module,recycling material module and decision analysis module.The information input module sets basic engineering information;the building material module calculates carbon emissions at all stages of the life cycle of materials;the recycling material module calculates carbon emissions at all stages of the life cycle of recycled materials and raw materials;the decision analysis module displays carbon emissions calculation results and gives strategic suggestions based on the selection of building materials with minimum carbon emissions.The carbon emission calculation system of building materials can meet the requirements of carbon emission calculation of engineering projects through testing.This thesis presents the carbon emission calculation results of building material carbon emission calculation system based on the actual case of 15#building renovation project.Through comparative analysis,it can be seen that compared with other systems,the carbon emission calculation system designed in this thesis is more effective than that of other systems.The calculation results of the carbon emission calculation system for building materials can provide more comprehensive data support for energy conservation and emission reduction strategies for building materials.At the same time,it has the advantages of adapting to local conditions,strong operability and complete and accurate calculation.
