How do we measure the sustainability of a green data center?
Assessing the sustainability of a green data center involves vital metrics related to energy and environmental design, where Power Usage Effectiveness (PUE) and Carbon Usage Effectiveness (CUE) play pivotal roles.
PUE (Power Usage Effectiveness)
PUE, devised by the Green Grid Association, key metric to assess overall energy efficient of the data by comparing total power usage to the power delivered to IT equipment. An ideal ratio of 1.0 signifies perfect efficiency, with all power reaching IT equipment without losses in cooling or transmission. Targeting a PUE equation below 1.5 is standard, while green data centers can achieve an impressive PUE of less than 1.1.
The formula to calculate PUE – PUE= total facility power/IT equipment energy
Total facility power means the entire power consumed by the facility, encompassing all data center hardware, cooling systems, power distribution components, and lighting installations. On the other hand, IT equipment energy specifically denotes the energy utilized to operate storage and networking equipment, along with control devices like workstations and monitors.
How can you calculate the power usage?
Accurate measurement of power consumption is essential for calculating PUE. If the data center is in a place with other offices, only look at the meter that gives power to the data center. If it is not on its own meter, identify how much energy other parts of the building use and take that away (subtract). Or leverage Data Center Infrastructure Management (DCIM) software with sensors that show how much energy is being used in real-time.
CUE (Carbon Usage Effectiveness)
Complementing PUE, CUE measures a data center’s carbon emissions efficiency. The Environmental Protection Agency (EPA) sets standards for measuring carbon emissions in data centers. It calculates the ratio of total CO2 emissions from energy consumption to the energy consumption of IT equipment.
The formula to calculate CUE – CUE = CO2 Emissions Caused by Total Data Center Energy / IT Equipment Energy
In an ideal scenario, CO2 emissions data would be sourced from real-time CO2 meters, which gather information directly from the local power source—let it be diesel/ natural gas/ fuel/ oil/ turbines /coal /generators/fuel cells, or any other applicable source. However, suppose access to real-time CO2 emission data is unavailable. In that case, the alternative involves performing calculations based on data provided by the generator manufacturers, accounting for both emission rates and fuel sources.
These metrics comprehensively evaluate a green data center’s environmental impact and efficiency. And if it’s high, businesses can look out for assessing and implementing better practices.
