A Preliminary Study On Carbon Emission Measurement Of Components Recycled Building Products

With the increasing demand of carbon emissions reduction in the construction industry worldwide,how to correctly and effectively calculate carbon emissions of buildings has become a concern.Quantitative calculating carbon emissions of buildings,to scientifically evaluate the low carbon level meets the development trend and the time requirement.Now,for the measurement of building carbon emissions,there is no mature method in China.The components recycled building products are a new type of buildings which can be produced in large quantities and are environmentally friendly.The components can be recycled and building can be removed and reconstructed.Now,there is no carbon emissions measurement method for this kinds of building products.Since the components recycled building products is based on component design and management as the core of building design,so measurement methods for this kind of building products take the components as the basic unit instead of taking the materials and mechanical equipment as the basic measuremtn unit traditionally.This article establishes carbon emissions measurement methods for this kind of building products based on current research to verify its low carbon level effectively.It also provides ideas for the carbon emissions measurement of other types of industrial buildings.In this paper,the carbon emission measurement method of components recycled building products is studied,including:(1)Studied the characteristics of the component recycled building products,such as using componentsas core elements and the components can be recycled.(2)The characteristics of the component recycled building products and the existing carbon emissionsmeasurement methods were integrated,and established carbon emissions measurement methods bycontrolling components,such as the recycled building life cycle and the inventory analysis usingcomponents as the core.(3)Building information modeling also uses componts as the core element.Choosed buildinginformation modeling as measuring tools and raised the application framework of componentsrecycled building products carbon emissions to make the measurement more accurate and simple;(4)Applied the research to a practical case to measure the carbon emissions of the light steel structurebuilding of Southeast University and verified the feasibility of the method.This research promotes energy conservation and emission reduction in the construction industry,and promotes the development of components recycled building products.
