Energy savings and emission reductions can be gained by harnessing shallow geothermal energy, and canprovide support for the sustainable development of new towns. Using a case study of shallow geothermal geologicalconditions in Jiangwan （a new town in Yangpu district, Shanghai）, this paper analyzes the static geothermal reserves and thepotential for exploitation. Combined with the planning and control targets for this new town, an analytical hierarchy processis used to analyze the applicability of the shallow geothermal energy for use in different types of building and to evaluate theeconomic and environmental benefits of exploiting the geothermal system. The results show that the utilization efficiency ishighest for multilayer residential building types and school buildings. The shallow geothermal energy resources in Jiangwancan supply cooling for a building area of 2.09 × 104 m^2 in summer and heating for a building area of 3.43 × 104 m^2 in winter.Buildings using the shallow geothermal energy can save 4.85 kg/m^2/yr standard coal equivalent, and can reduce CO2emissions by 12.01 kg/m^2, SO2 emissions by 0.10 kg/m^2, and particle emissions by 0.05 kg/m2 per year.
