Since the beginning of the 21st century, there has been a growing call for public attention on low carbon emissions and reduction of energy consumption in the world. Nowadays, about 40% of the world's total energy is consumed by buildings. Through effective design of building form, reasonable planning and layout of the building group, energy consumption of buildings can be reduced. This paper focuses on teaching building. Taking the teaching building of Jiulonghu Campus of Southeast University as an example, it analyzes the energy consumption of teaching building in the geographical environment of the campus, focuses on the surrounding buildings’ impact and changes on the energy consumption and researches on how radiation changes with different building spacing. This paper chooses Rhino automatic modeling platform and Grasshopper visual node programming plug-in and decides on Energy-plus as simulation tools. The results shows that when the building spacing increases by 1.1 times, the overall solar radiation increases and the total thermal load decreases by 0.479%. When the spacing is reduced by 0.9 times, the overall solar radiation is reduced, but the overall thermal energy consumption is reduced by 1.336%, which is more than the energy saved by increasing the spacing by 1.1 times.
