Scope: This document specifies the energy efficiency level and technical requirements, statistical scope, testing and calculation methods of data centers. This document is applicable to newly built and rebuilt and expanded data centers, as well as energy consumption measurement, energy efficiency calculation and assessment for single or modular units of data center buildings that use independent power distribution, air cooling, and electric air conditioning. This document does not apply to edge data centers. Data centers using other non-electric air-conditioning equipment can refer to this document. Note: A new data center refers to a data center that has been newly constructed by the construction unit in accordance with the prescribed procedures. Reconstruction of a data center means that the construction unit transforms an existing building into a data center, or remodels an existing data center computer room into a new data center. Expansion of a data center refers to a data center in which the construction unit expands its business capabilities by increasing the number of data center cabinets or increasing the power consumption of the cabinets in order to expand the business capabilities of the data center. Edge data center refers to a small-scale data center that is deployed at the edge of the network and close to the user side to realize functions such as edge data calculation, storage, and forwarding. The size of a single unit does not exceed 100 standard racks.
