Abstract: Reducing building energy consumption is considered as an important approach to achieving China's low-carbon development goals, while clarifying the correlation between urban land use and residential building energy consumption is of great significance to urban low-carbon transformation. In light of this, this paper selected 16 residential buildings in Changxing County, Zhejiang Province as samples and established buffer zones every 200m within a 2000m radius around each sample. Then, based on the entropy method and the accessibility analysis method, the land use mix in each buffer zone were measured and the correlation between the intensities of residential building energy consumption and land use mix was explored on periodical and monthly bases. The results show that: (1) From the perspective of time, the energy consumption intensities of residential buildings on January were the most significantly affected by land use mix. (2) In terms of area, the correlation between the energy consumption intensity of residential buildings and land use mix was mainly concentrated in the buffer area between the 1000m and 1400m radius around the sample buildings, while the land use mix within the 400m radius surrounding residential buildings had no effect on the energy consumption intensity. (3) Both measurement methods of land use mix use displayed strong levels of correlation, but the entropy index measurement method was proved to be more effective in revealing the relationship between land use mix and residential building energy consumption.
