Prior to the economic downturn, the movement for environmentally friendly or “green” practices had begun carving out a small but noteworthy niche in the healthcare IT industry. According to a 2008 survey by CDW Healthcare, 57 percent of providers had plans to actively pursue energy-efficient IT/recycling practices by 2009, and 21 percent said green IT policies guide the majority of their purchasing decisions.
But when the recession hit, and health systems across the country suddenly had to deal with capital freezes and layoffs, green initiatives were forced to take a backseat. Some organizations, however, have been able to forge ahead with eco-friendly plans by tying them to financial gains. What these leaders have discovered is that green initiatives - if done right - can lead to more greenbacks.
“The major driver is the fact that healthcare, as well as every other industry, is spending more and more each month on utility bills,” says Stan Schatt, vice president and practice director at New York-based ABI Research. “Utility bills are going up and becoming an increasingly larger part of the IT budget, and data center space is at a premium. Those are going to be drivers that will push organizations toward this movement. In other words, their own economic well-being is going to drive them.”
There's also the public image factor. Schatt says, as public awareness of environmental issues and green initiatives continues to grow, patients will start to question whether providers are taking the necessary steps to reduce their carbon footprint. And a number of health systems are responding by installing motion-sensitive lights, and implementing recycling programs for computers, X-ray film and other items. Others are incorporating features into building design that reduce consumption of electric power and limit water usage, and utilize materials that don't require solvent cleaners.
But while many executive leaders would certainly like to integrate eco-friendly programs into their strategies, they're finding that green IT won't fly if it doesn't make financial sense. At Phoenix Children's Hospital, Vice President and CIO Bob Sarnecki says, “You have to go ‘practically green’ before you go ‘real green.’ And that usually happens at the point where equipment starts to get old and needs to be replaced.”
That's where the vendors come in. According to an ABI Research report authored by Schatt, companies such as IBM, Hewlett-Packard, Dell and Cisco are offering more products in the way of virtualization software, and featuring equipment that promotes environmental responsibility. “What's happening is, as healthcare facilities go through the normal replacement cycles, the equipment they purchase is going to be more energy efficient,” he says. “It's going to come through the fact that vendors are changing their product mixes to offer greener products. This, by its nature, will make hospitals greener than they were before.”
For organizations looking to reduce their carbon footprint, the logical starting point seems to be the data center, one of the biggest culprits of power usage.
At Phoenix Children's, an organization that has adopted “tree-hugger thinking,” greening the 1,500-square-foot data center was done more out of necessity, says Sarnecki. “Like most IT organizations, we're constantly struggling for more power and more air conditioning. And not just the initial power in, but the UPS (uninterruptible power supply) you need if the power fails to come in. So we've had to do a lot just to get more efficient.”
The organization achieved that goal by installing a secondary chilling system in the data center, which had been using the same system as the rest of the hospital. The data center chilling system is only used throughout the hospital when the desert sun is at its strongest, usually in July and August.
Schatt says this type of thinking is becoming more common. “We're seeing a lot of innovation when it comes to greening of the data center. For every dollar that's spent for power consumption, you're spending another dollar to cool the equipment and cool the room. Now, we're starting to see technologies with very innovative ways of keeping equipment running cool.”
Another trend gaining momentum is virtualization. Phoenix has started transitioning physical servers to virtualized servers, resulting in a much smaller footprint. “It's been a real savings in power and AC,” he says. “My data center is cooler now than it was six months ago. Even though we've added new servers to the mix, we've actually reduced the physical footprint within the data center substantially.”
At Beth Israel Deaconess Medical Center (BIDMC) in Boston, the IT staff has leveraged virtualization to keep the data center at under 200 kilowatts, despite 25 percent growth every year for storage. According to CIO John Halamka, M.D., the department has added 305 virtual servers and just 16 physical servers since 2005. “The place where you see real measurable reductions in power is in the data center, where we've done extensive use of VM-ware, and we have really tried to look at power and cooling,” he says.
