Abstract

In the context of global warming and carbon emissions from the construction sector exceeds one-third of the total carbon emissions, reducing carbon emissions in the construction industry to slow down global climate change has become particularly important. Currently, the Chinese government vigorously promotes prefabricated buildings, and light steel structure is one of the forms of prefabricated construction, which has vast application prospects in rural areas in China. However, there is less research on carbon emissions of assembled light steel structural (ALSS) rural housing. In this paper, two rural houses were selected and studied, one made of light steel and the other made of brick and concrete, with the same design in Shimen village, Lin'an as an example. The aim of this paper is to calculate the carbon emissions of both types of rural houses and conduct a comprehensive comparison and analysis to clarify the emission reduction advantages of ALSS rural housing compared to brick-concrete structural (BCS) rural housing. The results of the study shows that in the materials production, transportation, construction, demolition and recycling stages, the ALSS rural housing has good carbon reduction effect than BCS rural housing.
