Green Data Center: Using Measurement Tools to Calculate Efficiency

Green Data Center

When it comes to designing a green data center, much can be done to promote energy efficiency and savings. Advanced technologies can help optimize roofs, walls, floors, layouts, cooling, lighting, server configuration and building management. The critical component of green initiatives is to properly plan the data center facility before equipment is installed.

Green Data Center

Green data center design efforts begin with the physical structure. Every detail of building construction is analyzed for efficiency. If not done during the design phase of a project, increasing efficiency becomes more costly, time-consuming and labor-intensive. And, the efficiencies gained after the fact may be limited.

  • Incorporating green data center design from the start of a building project ensures the best levels of efficiencies and cost savings. Plus, businesses are better positioned to qualify for utility rebates, tax credits and other energy efficiency incentives.

Knowing How to Measure a Green Data Center

  • Data centers are well known culprits for consuming vast amounts of energy. Not only costly, this energy consumption hinders good corporate citizenship. Therefore, today’s data center managers are measuring efficiency so they have a guide for improvements.

  • One industry measurement tool is the Power Usage Efficiency (PUE) metric. This measurement will tell a data center operator where they stand in terms of energy efficiency. The company can then develop strategies to lower its PUE rating.

  • PUE ratings are a good start for becoming a green data center and provide a baseline measurement. Industry sources publish ratings from which data center operators can compare their facilities.

  • The benefit of using a PUE rating for green data center goals is the consistent method of measuring energy consumption it provides. As the data center evolves with new technologies and equipment, the PUE rating can highlight the effects on energy efficiency.

  • The calculation involves a ratio of power available to power being used. The result of this calculation will be a factor greater than one. Therefore, the higher the calculated ratio, the less efficient energy consumption is in the data center.

  • Another measurement tool is the Data Center Infrastructure Efficiency (DCiE). As the inverse of PUE, DCiE is the ratio of energy used in the data center compared to the total power available. The result will be less than one, with the best efficiency ratings being the closest to one. To help a company’s green data center initiatives, online tools exist to help calculate these measurements.

The Importance of PUE and DCiE Measurements

  • In addition to providing a baseline measurement for data center efficiency, PUE and DCiE calculations can provide crucial decision-making information. When companies commit to operating a green data center, they can decide if it makes better sense to build a new facility or enhance an existing one.

  • These measurements also help with goal setting. For example, once a PUE rating is established, the company can set a goal to lower it to a certain number. To achieve this goal, the company develops strategies to improve energy consumption levels.

  • Power and cooling are prime targets for energy efficiency increases. The data center managers can develop strategies to reduce power consumption and improve cooling system operation. Some of these efforts can be straight-forward and make good economical sense. Other times, the existing data center might be at the end of its lifecycle and need replacement.
