Energy: Let the label be your guide

Small conversions and practical planning help create a win-win in energy consumption

In 1992, the U.S. Environmental Protection Agency (EPA) developed the ENERGY STAR® program to promote and identify products that were energy efficient and safe for the environment. The first items tagged with the ENERGY STAR seal were computers and monitors. As the program evolved, the list of rated products continued to grow. In 1996, the Department of Energy (DOE) struck a partnership with the EPA and today-17 years later-the ENERGY STAR designation and label can be found on products ranging from light bulbs to appliances to building materials in a public-private energy-conservation effort.

EnergyGuide labels

Bearing the ENERGY STAR logo, the familiar yellow and black EnergyGuide labels are found on most energy-using products subject to minimum standards set by the federal government. Note: Items such as dryers and range/ovens are exempted from the program because they must meet minimum efficiency standards and there is currently little differentiation from model to model.

Read the label

  • On the left side under EnergyGuide is the description of the type of appliance and its features. The right side of the label indicates the manufacturer, the model numbers that fit the description, and its capacity.

  • In the information box, the estimated annual amount of energy that the particular model will use in a year is provided.

  • The line scale that follows shows the energy consumption estimated for models of comparable size and type.

  • The next paragraph gives the range of model sizes in this comparison.

  • At the bottom of the label is an estimate of how much this device will cost to run annually.

The EnergyGuide label, however, does have its limitations. For example, the annual operation cost will depend on whether natural gas or electricity is the energy source-it compares only costs of similarly run products. Also, when using the guide, be sure to compare similar size and models of products-if shopping for an air conditioner be sure specifications are similar and that the purchasing decision isn't based on faulty comparison.

Yet regardless of its limitations, the EnergyGuide remains a good tool for gauging energy efficiency and costs of ENERGY STAR rated devices to rated and nonrated products.

Even in these challenging economic times, Americans still need to be environmentally responsible. Energy-efficient equipment and behaviors can decrease operational costs, improve the environment, and enhance your facility's reputation.

Steven J. Kismohr, AIA, LEED AP, of GreenWorks Studio, a partner company of architectural firm Harley Ellis Devereaux, explains that the ENERGY STAR rating program enables the EPA and DOE to increase efficiency rating standards for products and practices. “Any product that receives an ENERGY STAR label,” says Kismohr, “is at least 30% more efficient than standard products.” He advises purchasers to make a conscious effort to look for the ENERGY STAR designation when selecting new or replacement equipment, comparing the equipment's features against other like products. “Awareness is growing, especially on the coasts where energy costs are higher,” he states. Kismohr adds that conservation will play an even bigger part in equipment selection as energy prices are predicted to continue to escalate.

There are expenditures to acquiring ENERGY STAR products, explains Kismohr. “However, it's not necessarily high-end TVs, appliances, or electronics that carry the label. Generally, it's the more middle-of-the-road product offerings that are manufactured to conserve energy. The consumer has to research, look, and be aware,” he advises.

Becoming “green”

Lighting is the easiest “first step” in reducing energy usage and experiencing savings. “Change out the incandescent bulbs for CFLs [compact fluorescent lamps]. For larger fixtures using T12s, upgrade them to T8 and even T5 bulbs/lamps throughout the facility-indoors and out,” recommends Kismohr. “Don't just stop at light bulbs but see if it's possible to upgrade light fixtures to ENERGY STAR rated products to achieve additional savings, as well.”

Kismohr describes two separate sides of the equation to consider when upgrading a facility-the office side and the residential side. “On the office side, the first equipment upgrades would be the computers and monitors. There can be significant energy savings when standard monitors are replaced with flat-screen or LED monitors. If the same equipment is replaced with computers and monitors bearing the ENERGY STAR logo, up to a 90% savings can be realized. How much is that? Not a lot, probably $5 savings in the Midwest where energy costs are lower. However, if you multiply that by the number of computers and monitors throughout your organization-office, nursing, resident rooms-the amount of savings can be exponential,” explains Kismohr.

The facility side of the equation also can be retrofitted with ENERGY STAR rated products. “Foodservice operations can greatly benefit from reduced energy equipment,” says Kismohr. In that environment, steamers, dishwashers, refrigerators/freezers, ice machines, and other cooking equipment often use a lot of energy. Replacing them with energy-saving appliances can greatly decrease operational costs. “This is a great way to incrementally renovate and upgrade a facility,” adds Kismohr.
