Carbon Emissions of Discarding and Demolition Stage for Teaching Building
Publication: ICCREM 2021
ABSTRACT
The building sector is significant consumer of energy and natural resources, as well as significant construction to carbon emissions worldwide. It is expected to have great potential for emission reduction. The life cycle of teaching building generally includes the raw material production stage, construction stage, operation stage, and discarding and demolition stage. However, the current quantitative studies on carbon emissions of teaching building mostly focus on the construction stage and operation stage, and few studies have considered the discarding and demolition stage. To address this issue, this study focuses on the discarding and demolition stage of teaching building and pursues quantitative research. According to the life-cycle assessment (LCA), the discarding and demolition stage is divided into four stages: demolition, onsite sorting, transportation, and recycling. The process analysis is used to establish a carbon emission calculation model based on the demolition stage of teaching building, and empirical analysis is also made. This paper can provide strategies for the effective emission reduction of building sector.
