This paper focuses on low-rise prefabricated buildings in Chongqing, analyzes the impact of Chongqing’s regional characteristics on the carbon emissions during the building’s materialization stage, constructs an LCA carbon emission accounting model, and conducts empirical analysis and calculation through a case study. It then identifies key influencing factors and proposes carbon emission reduction path optimization suggestions based on Chongqing’s regional characteristics. This research provides data support for the low-carbon development of similar mountainous buildings and offers a reference for embedding regional characteristics in building carbon emission reduction research.

摘要

This paper focuses on low-rise prefabricated buildings in Chongqing, analyzes the impact of Chongqing’s regional characteristics on the carbon emissions during the building’s materialization stage, constructs an LCA carbon emission accounting model, and conducts empirical analysis and calculation through a case study. It then identifies key influencing factors and proposes carbon emission reduction path optimization suggestions based on Chongqing’s regional characteristics. This research provides data support for the low-carbon development of similar mountainous buildings and offers a reference for embedding regional characteristics in building carbon emission reduction research.
