In order to promote the energy use management of inefficient data centers and help them develop intensified, green and intelligently, Beijing recently issued the "Beijing Inefficient Data Center Comprehensive Governance Work Plan" (hereinafter referred to as the "Governance Plan").
What is an inefficient data center
Inefficient data center mainly refers to the following three types:
PUE (power supply efficiency, the closer it is to 1, the higher the energy efficiency level) data center with a value of more than 1.4;
low-utility data centers such as backup storage data centers with an average single rack power of less than 2.5 kilowatts or an average shelf rate of less than 30%;
data centers with higher water consumption (specific standards will be formulated separately).
Focusing on improving the carbon efficiency level of inefficient data centers, the "Governance Plan" proposes a series of measures:
find out the stock base, strengthen online monitoring
in accordance with the law and regulations to strengthen online monitoring of energy and water consumption in large data centers. It was the first to complete the energy consumption real-time monitoring data of all 26 large data center enterprises that consume 5,000 tons of standard coal and above (equivalent value, the same below) and provide third-party services to access the Beijing Energy Saving Monitoring Service Platform. On this basis, the self-use data center will be connected to the platform for annual energy consumption of 5,000 tons of standard coal (including) and self-use data centers in stages and batches, laying a solid foundation for online monitoring of PUE values and subsequent supervision and law enforcement. Install remote intelligent water meters in stages and batches in large data centers, and perform separate water use accounting and classified and classified statistical records to lay a solid foundation for online monitoring of WUE values and subsequent supervision and law enforcement. Gradually improve the ledger of small and medium-sized data centers.
Improve energy consumption and water consumption and carbon emission control
implements energy evaluation and delay approval for areas where energy consumption intensity or carbon intensity does not decrease but increases, or areas where annual energy consumption levels do not meet the standards or individual projects. Large and efficient data center enterprises are encouraged to integrate existing inefficient data centers in the city. Data center implementation plan (quorum) water use management, and strictly implement the progressive price increase system beyond the plan (quorum).
Current status of energy consumption and carbon emissions in data centers
Data center energy consumption and carbon emissions throughout its entire life cycle. Among them, the operation stage is the most, including the operation of servers in the computer room, the refrigeration and operation of air conditioning equipment, electricity consumption of personnel in office areas, and electricity consumption of other devices and equipment. The "Green Data Center White Paper 2020" released by the China Institute of Electronic Technology Standardization pointed out that in recent years, the energy efficiency level of my country's data centers has been continuously improving, with the average power utilization rate (PUE) of super-large data centers being 1.46. Some excellent green data centers have been leading the world, and PUE can reach 1.2-1.3. However, the total energy consumption of my country's data centers is still growing rapidly, significantly higher than the world average. On the one hand, this is because the scale of data center construction in my country is growing rapidly; on the other hand, there is a lot of room for improvement in energy conservation in my country.
According to estimates, by 2021, the national data center rack scale (standard rack is a conversion unit, with a power of 2.5 kilowatts as a standard rack) will reach 5.436 million, an increase of 27% over 2020; the power utilization rate (PUE) will reach 1.35, and the carbon emission intensity (CUE) will be 0.82. In 2021, the national data center energy consumption will reach 216.6 billion kilowatt-hours, an increase of 44% over 2020, accounting for about 2.6% of the total electricity consumption of the whole society; the carbon dioxide emissions of are about 135 million tons, an increase of 39.15 million tons from 2020, accounting for about 1.14% of the national carbon dioxide emissions.
What is the online energy consumption monitoring platform
energy consumption online monitoring system, also known as the energy information monitoring system. By sub-item measurement, collection, transmission and monitoring of energy consumption data such as electricity, heat, water, coal, temperature, etc. of energy consumption units, a digital and visual energy management system is finally realized.The system is carried out based on information technology such as computer network, wireless communication , metrology and collection, and can reflect the dynamic changes of data and store and query historical data. It can be used for energy consumption statistics, energy conservation diagnosis, energy efficiency management, analysis and decision-making, enterprise energy scheduling, etc.

Cornwath IoT energy consumption management platform refers to the unified monitoring and management of water supply, power supply, air supply, air conditioning and other related energy of buildings, building an energy consumption analysis platform, providing an effective basis for energy consumption monitoring and analysis, realizing centralized management of data, and achieving the purpose of improving quality, increasing efficiency, reducing costs, and reducing storage.
Cornwax IoT ctrlworks energy consumption management platform consists of the terminal layer, network layer, platform layer, and application layer. It collects data from water, electricity, gas and other energy in building buildings through intelligent hardware equipment, and transmits data through the network layer to realize visual monitoring of data, monitor the use and consumption of water, electricity, and gas, and form various data charts for building operators to refer to data and formulate energy-saving measures.
In recent years, the company has continuously explored and practiced in public buildings such as offices, hotels, hospitals, culture and education, transportation hubs, and large venues. It has many successful cases of building energy-saving green transformation projects, and actively promoted the development of my country's building energy-saving and the realization of dual-carbon goals.
As a domestic brand that has deeply cultivated the field of building automatic control , Cornwall IoT is born with the gene of "energy saving". Since its establishment, the company has been committed to achieving energy conservation and carbon reduction in buildings, and has actively participated in the energy conservation and carbon reduction cause. It has accumulated rich experience in the field of energy conservation in public buildings. Through its independently developed software and hardware products, it provides buildings with scientific and intelligent energy management solutions, empowers building energy management, and builds green building .
