In order to solve the problems of low energy utilization efficiency and many shortcomings in environmental and economic aspects of traditional single heating forms, it is considered to organically combine the green sustainability of renewable energy with the stability of conventional energy. Taking a deep geothermal energy+multi energy complementary heating project in a university campus in southern Hebei as an example, the project overview, energy supply plan, and energy station construction were introduced, and the system operation and testing data were organized and analyzed. The results show that the system operates well, saving 20 860 tons of standard coal annually, reducing 54 650 tons of carbon dioxide annually, reducing 175 tons of sulfides, 154 tons of nitrogen oxides, and approximately 210 tons of waste residue. The economic and environmental benefits are significant.
