Introduction of T/AIAC 004-2023

Evaluation standard of zero-carbon data center 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. GB/T 384 Petroleum products - Determination of heat of combustion GB/T 11062 Natural gas - Calculation of calorific values, density, relative density and Wobbe indices from composition GB 17167 General principle for equipping and managing of the measuring instrument of energy in organization of energy using GB/T 32910.3-2016 Data center - Resource utilization - Part 3: Electric energy usage effectiveness requirements and measuring methods 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.
