What is BS EN 50600-4-7 about?
BS EN 50600 discusses information technology. BS EN 50600 series specifies requirements and recommendations for supporting various parties involved in the design, planning, procurement, integration, installation, operation and maintenance of facilities and infrastructures within data centres. 
BS EN 50600-4-7 seventh subpart of fourth series that specifies Cooling Efficiency Ratio (CER) as a Key Performance Indicator (KPI) for quantifying the efficient use of energy in order to control the temperature of the spaces within the data centre.
BS EN 50600-4-7 specifies:
- The Cooling Efficiency Ratio (CER) of a data centre.
- The relationship of this KPI to a data centre’s infrastructure, information technology equipment and information technology operations.
- The measurement, the calculation and the reporting of the parameter.
- Information for correct interpretation of CER.
Who is BS EN 50600-4-7 for?
BS EN 5060047 on cooling efficiency ratio is useful for: 
- Installers and maintainers 
- Equipment manufacturers and suppliers 
- Architects, system and installation designers 
- Facility and infrastructure integrators 
- Facility managers, ICT managers, project managers and main contractors 
- Network operators 
Why should you use BS EN 50600-4-7?
A data centre is used for housing and supporting information technology and network telecommunications equipment for data processing, data storage and data transport.  But these data centres need to provide more modular, scalable and flexible facilities and infrastructures to easily accommodate the rapidly changing requirements of the market. 
The need of data centres varies in terms of purpose, security, size, accommodation, availability of service and objectives for energy efficiency. 
In this regard, CER quantifies actual heat load and electrical power used by a cooling system. 
BS EN 5060047 specifies the CER to quantify the use of the energy for controlling the temperature of the spaces within the data centre.
BS EN 5060047 helps in providing information that is useful and efficient for various parties involved in installation or operating data centres. 
BS EN 5060047 helps in quantifying the energy that is used in data centres and thus, helps in maintaining a report of reused energy for evaluation purposes to become more energy efficient. 
BS EN 5060047 helps in measuring and calculating cooling efficiency ratio to assess whether the data centres are resource-efficient thus to helps in reducing wastage of resources.  
Compliance with BS EN 50600‑4‑7 will help you establish data centres that are more energy-efficient and environment friendly, by incorporating the concept of sustainability in the information technology sector.
