1 Scope
This document specifies the basic requirements, evaluation indexes and evaluation grades for zero-carbon data centers.
This document is applicable to the evaluation of zero-carbon data center.
2 Normative references
The following documents contain requirements which, through reference in this text, constitute provisions of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
data center
building site that provides an operating environment for centrally placed electronic information equipment, which may be a park, one or several buildings, or a part of a building, including a host room, auxiliary area, support area, and administrative management area
[Source: GB 50174-2017, 2.1.1]
3.2
greenhouse gas
gaseous constituent of the atmosphere, both natural and anthropogenic, that absorbs and emits radiation at specific wavelengths within the spectrum of infrared radiation emitted by the Earth's surface, the atmosphere and clouds
Note: Unless otherwise specified, the greenhouse gases in this document are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCS), perfluorocarbons (PFCS), sulfur hexafluoride (SF6) and nitrogen trifluoride (NF3).
[Source: GB/T 32150-2015, 3.1]
3.3
carbon dioxide equivalent
CO2e
unit for comparing the radiative forcing of a greenhouse gas to that of carbon dioxide
Note: The carbon dioxide equivalent is calculated using the mass of a given greenhouse gas multiplied by its global warming potential.
[Source: GB/T 32150-2015, 3.16]
3.4
global warming potential
GWP
factor describing the radiative forcing impact of one mass-based unit of a given greenhouse gas relative to an equivalent unit of carbon dioxide over a given period of time
[Source: GB/T 32150-2015, 3.15]
3.5
data center accounting boundary
range of greenhouse gas emissions related to the normal operation of infrastructure equipment and electronic information equipment in the data center
Note: Infrastructure equipment includes but is not limited to the power supply and distribution system, HVAC system, water supply and drainage system, intelligent system, fire protection system, heating system, park public transportation system, etc. within the data center.
