[#DataCenter #データセンタ] データセンタの省電力レベルを計測する指標としてEnergy Starが2010年4月に適用開始予定 =>

これは、Leed Certificationと同様に、今後データセンタ向けの評価基準として採用されるケースが増えると考えられる。  Energy Starはアメリカエネルギー省の機関である、EPAが提唱している指標ですでに業界に広く普及しており、今回はデータセンタ専用の指標が作られることに。 

100点満点で、75点満たしていればStar Markが取れる。


Should we begin preparing for Energy Star for Data Centers scheduled for 2010?

If you own, operate, design or are in some way involved with the data center industry you are likely curious about any government program that could impact you and your data center facility. In 2008 data from participating data centers was collected by the Energy Star program to help begin the process of developing an Energy Star program for data centers. Over 120 data centers submitted data and the EPA is currently finalizing the rating model with an anticipated release date in April 2010.

According to the EPA, the Energy Star rating for datacenters plans to build on the existing Energy Star platform for buildings by using a methodology similar to existing building Energy Star ratings (1-100 scale). The EPA plans for the Energy Star rating for datacenters to be usable for both stand-alone datacenters and datacenters located within office or other buildings. Similar to buildings, the EPA plans to offer the Energy Star label to datacenters with ratings of 75 or higher.

As part of the program the rating for data centers shall be based on the now recognizable PUE or Power Usage Effectiveness metric developed by the Green Grid.  PUE is calculated by taking the total energy and dividing it by the UPS (Uninterruptible Power Supply) energy. 

Over the past year there have been some rumbling regarding the use the Uptime Institute’s tier rating system, but recently the EPA has dropped including the Tier rating system noting that it would complicate the rating system.

What does this all mean to existing and future data center owners?

Before jumping into what you should do here is some information that provides additional clarification on the Energy Star for Data Centers. The new rating system is based on actual as-billed energy data and will serve as a whole building indicator. The rating compares a building’s energy performance to its national peer group – not other buildings in Portfolio.

Additional notable bullet points include:

• Build on existing ENERGY STAR methods and platforms. Methodology similar to existing ENERGY STAR ratings (1-100 scale).
• Usable for both stand-alone data centers, as well as data centers housed within office or other buildings.
• Assess performance at the building level to explain how a building performs, not why it performs a certain way.
• Provide users with information and links to additional resources to aid in their efforts to determine next steps after receiving an energy performance rating for their building.
• Offer the ENERGY STAR label to data centers with a rating of 75 or higher (performance in the top quartile).

Much like data center owners utilize their LEED certification for their data center to help promote their facility so will the new Energy Star for Data Centers rating system. The difference between the LEED and the Energy Star program is that the Energy Star program simply rates you based on your building performance and does not suggest on how to get there like the LEED program does. In addition, the LEED program does not have a specific category as of yet for data centers (currently being worked on), whereas the Energy Star for data centers program is catered specifically for it.

Will end users embrace this rating system? Yes, we believe the rating system will be embraced and In particular those third party providers who are eager to utilize the rating attachment to their facility for marketing purposes.  For everyone else it is an excellent way to measure your facility not to mention this rating system may be part of a future tax and credit program.
