Abstract: With the continuous acceleration of urbanization in our country, requirements for building comfort level are constantly increasing. Large public buildings have a higher energy consumption intensity, the cooling and heating energy consumption accounts for nearly 60% of the total energy consumption. After the “dual carbon” target was proposed, reducing the energy consumption of public buildings is a necessary path for building energy conservation and green building implementation. This article takes a newly building hospital in a cold winter and hot summer area as an example to simulate and analyze its heating and cooling load. Based on the load demanding and the characteristics of regional energy supplying, a photovoltaic + ground source heat pump system is adopted, combined with regional heating and green electricity, to configure a multi energy collaborative cold and heat supply system suitable for cold winter and hot summer areas. This system not only has good energy-saving and carbon reduction advantages, but also has significant economic benefits compared to conventional “water-cooled units + gas boilers” for energy supply. It has certain promotional significance in large-scale public projects in cold winter and hot summer areas.
