Earth Day typically inspires widespread environmental introspection. How can we cut down on waste? Can we be more efficient? Are we actively pursuing “greener” operations? And how can we reduce our costs and be fiscally responsible?

Houston is recognized as the energy capital of the world, so it may be a surprise to learn that amidst that distinction The Planet does its part to reduce energy costs. In fact, we have been featured in several “green technology” articles over the past few months and acknowledged for our common sense approach. Ultimately, we look to save money, reduce consumption and improve data center efficiency. And in the coming weeks, we’ll announce an expanded program that takes us to the next level in increasing those efficiencies.

Tier1 is a leading research firm, and Martin Levy is the firm’s “green” analyst. In his report on The Planet, his headline was simple: “Down-to-earth solutions help improve efficiency at The Planet.”

Martin goes on to say the following:

Not a word about carbon offsets. Nobody planting trees. Nothing about Renewable Energy Credits (RECs). No recycling bins at the entrance to the datacenters. Instead, today’s announcement from The Planet was all about core datacenter efficiency. The company runs six datacenters and because of a focus on efficiency, it expects to save over one million dollars during 2008 … T1R is impressed. The Planet has shown that going green can be done the old-fashioned way. Make the technology work better and the company sees a positive ROI. That’s still good for the environment and even better for the bottom line!

Our facilities team is always on the lookout for new ways to reduce energy costs, since it’s one of our biggest expenses. Our vice president of facilities, Jeff Lowenberg, took an interesting challenge at the end of last year: Cut power costs by $1 million dollars in 2008, while we continue to grow and provision new servers in our six world-class data centers.

In his Sustainable IT blog, Ted Samson reported on a few of the initiatives aimed at improving our efficiency:

• Rearranging floor tiles to better manage cold airflow
• Installing seals and grommets in the ceilings, walls, and floors to reduce bypass airflow
• Installing blanking plates in server cabinets to direct airflow more efficiently
• Sealing power distribution units to reduce bypass airflow

Ted also explained the significance of those “minor” improvements:

Cool air was going to only where it was needed: the server intakes … Six months later, the company finds that its efforts have paid off substantially. Even though critical server loads increased by 5 percent, the facility’s overall cooling power needs dropped by 31 percent … The Planet also improved its “coefficient of efficiency,” an EPA- and Uptime Institute-recognized measurement of the total power necessary to operate a data center, divided by critical power, which represents the energy required to operate its computers. The company increased its rating to 1.7 – a near-ideal number – from its previous “good” ranking of 2.0.

Matt Stansberry at Search Data Center also spoke with Jeff about our progress and shared a few additional details in the quest to improve data center cooling:

Data center cooling is where most of infrastructure energy efficiency is lost. The fundamental rule in energy efficient cooling is to keep hot air and cold air separate … The Planet uses a method of extending the height of its computer room air conditioning (CRAC) units’ return-air plenums to optimize air cooling … By extending the plenums higher, it ensures that the CRAC units are not sucking in any cold air from the cold aisles, as it allows for the hottest air to be sucked into the units. In this scenario, the top of the plenums must be at least 2 feet from the ceiling.

To get an idea of what “plenums” are, you can visit Matt’s post or Heather Clancy’s recent article about The Planet at ZDNet’s GreenTech Pastures … and while you’re there, be sure to check out the post’s opening line.

To stay in the loop about what is being done in the “green tech” sphere, keep an eye on Ted Samson’s Sustainable IT blog, GreenerComputing, The Daily T1R from Tier1 Research, ZDNet’s GreenTech Pastures and Search Data Center.

And watch for more news from us.
