The Life-Cycle Energy Consumption Distribution of Buildings in China

Abstract:

In recent years, continues development of China urbanization gradually increases the energy consumption of buildings. Studies on the life cycle energy distribution of buildings have practical significance to determine energy policy formulation and adjustment. Based on previous studies and the composition of the life cycle energy consumption of buildings, this article constructed a life-cycle energy consumption model, and established the calculation methods of initial embodied energy, operational energy, reset embodied energy ,dismantle embodied energy and recycle embodied energy separately. Based on ICE material energy data and combined rating per machine per team, this article calculated the life cycle energy distribution of a building in Nanjing. We found that the life cycle energy of buildings obeyed normal distribution, the operational energy accounts for a large proportion and it decreases with the decreased life cycle of buildings. The recovery of operational energy can reduce the proportion of the initial embodied energy. Considering the studies, in order to meet the characteristic of the buildings in China which have short life cycle, we should focus on the development of building materials recycling and reusing.
