Functional evaluation index system and notes.

Control layer	Network layer	Network layer factors	Notes
Functional evaluation index system for the building’s cold source system A	Functional experience B1	Safety and reliability B11; Convenience of use B12; Flexible load adaptability B13; Difficulty of operation and maintenance management B14	The system functions are safe and efficient; the temperature is stable; and it is easy to maintain.
	Social and environment; l benefits B2	Degree of green environmental protection B21; Conservation of energy, reduction of emissions B22; Enhancement of architectural landscape B23	Green environmental protection means that the scheme adapts to the local ecological environment, attaches importance to building environmental protection, and makes full use of renewable resources. Energy-saving and emission reduction refers to the CO2 emission reduction and annual total electricity consumption generated by the same refrigeration capacity. Landscaping refers to the impact of the exposed facilities on the architectural landscape.
	Reliability B3	Energy supply B31; Energy-resource structure B32; Energy price fluctuation B33	The system offers flexibility of resource allocation and adjustability.
	Demonstrable advances B4	Use of modern techniques B41; Application of science and technology B42; Policy orientation B43	The project uses globally advanced technology and equipment and can be widely used in other projects. If the technology used is not referential, it actively responds to national policies.
	Project applicability B5	Natural conditions B51; Building scale B52; Building use B53; Installation area B54	Project applicability refers to the fact that different projects have different requirements for their cold and heat sources. The greater the degree of satisfaction, the better the applicability.
