Carbon emissions of macro-level buildings in China by life cycle energy analysis

摘要

There is great energy consumption in China whose newly-built constructions rank the top worldwide these years, which results in enormous greenhouse gas emissions. This study aims at analyzing the energy consumption of macro-level buildings system in China based on the theory of Life-Cycle Energy Analysis (LCEA), pointing out the key factors in every Life-Cycle phase of buildings and calculating the carbon dioxide emissions related to buildings. In the conclusion, it is indicated that the energy consumptions of building materials production and building operation account for largest share in building energy consumption. At last, the energy consumptions and carbon emissions of building from now to 2030 are calculated.
