With the revision of the Enforcement Decree of the New and Renewable Energy Act of 2019, the category of hydrothermal energy is expanding, and various hydrothermal energy technologies are developed and spread to develop hydrothermal energy as next-generation eco-friendly energy and renewable energy. The importance of hydrothermal energy is gradually expanding because it can reduce the cost of 20 ~ 50%, the power consumption energy and the carbon dioxide emissions compared to the existing cold heating system using fossil fuels by applying hydrothermal energy to cold heating and air conditioning systems of various buildings. Therefore, this study aims to contribute to the expansion and dissemination of next generation hydrothermal energy industry by applying hydrothermal energy system to buildings such as hospitals and data centers to provide various performance indicators such as COP and power consumption. The average annual cooling and heating COP was 3.53 and the average monthly power consumption was 364,442,825 kJ when the water heat source heat pump system with the water heat source as Daecheong dam was applied to hospitals with a size of 19011㎡. For Data centers with a size of 1000㎡, the average annual cooling and heating COP was 4.56 and the average monthly power consumption was 1,084,690,364kJ.
