Abstract The DEST model is used to simulate the energy consumption of typical civil buildings in Shenzhen, and the temporal and spatial characteristics of energy consumption of various types of buildings are summarized. The results show that different civil buildings in Shenzhen have different energy consumption characteristics in space and time. Residential buildings with low energy consumption per unit area are most widely distributed, and commercial buildings with limited numbers have the largest volume and high energy intensity, so the total consumption can not be ignored. Meanwhile, office buildings, most sensitive to the parameters change, have great energy saving potential. Combined with the development plan of Shenzhen 13th Five-year Plan, suggestions on the strategy of building carbon reduction in Shenzhen can be summarized as follows: 1) building a comprehensive smart city, creating an exhaustive monitoring network for measuring energy consumption of various types of buildings, managing energy consumption behavior more scientifically; 2) constructing green buildings in an allround way, implementing green building standards when constructing new buildings, and valuing the
