Big Data Characteristics of Embodied Carbon Emissions of Buildings
Embodied carbon runs through multiple stages of carbon emissions throughout the entire lifecycle of buildings,but the reduction of embodied carbon emissions has not yet received sufficient attention.This study is based on the carbon emission accounting and statistical analysis of nearly 140 under construction projects with a total construction area of over 16.7 million square meters in large-scale real estate enterprises.It summarizes four characteristics of embodied carbon emissions in buildings:the highest proportion of carbon emissions in building's whole life is from material production;the higher the latitude of the project,the higher the carbon emission intensity;concrete,rebar and metal materials are the key to focusing on and reducing embodied carbon;the carbon emission intensity during the construction process of prefabricated buildings is lower than that of non prefabricated building projects.Furthermore,based on the above characteristics,suggestions are proposed to promote carbon footprint disclosure of building materials products,optimize supply chain management,promote prefabricated buildings,and coordinate carbon reduction between construction and building materials.These measures will help achieve sustainable development of the construction industry.
