Investigation on Sustainable analysis of Building System from LCA-Emergy-Carbon emission perspective

Abstract

Currently, in the context of carbon neutrality, research on the ecological sustainability of building systems holds significant importance. This paper evaluates the sustainability of building systems by integrating the concepts of ecological emergy theory and carbon emissions calculation with systems engineering principles. The results indicate that the operational phase of buildings is the key contributor (accounting for approximately 79.6% of the total emergy and 97.9% of the overall carbon emissions), representing the highest amounts of emergy and carbon emissions within the entire building system. To enhance the ecological sustainability of building systems, the exploration and consideration of renewable energy subsystems have been conducted. This contributes to achieving low-carbon sustainable building practices and helps mitigate global climate issues.
