Wal-Mart to Open First High-Efficiency Store; Supercenter Expected to Use 20 Percent Less Energy

Wal-Mart Extends Environmental Efforts to Kansas City - Donates $110,000 in

In-Kind and Cash Contributions to Local Community

    BENTONVILLE, Ark., Jan. 18 /PRNewswire-FirstCall/ -- Wal-Mart Stores,
 Inc. (NYSE:   WMT) announces it will open tomorrow in Kansas City, Mo. the
 first in a series of High-Efficiency stores that will use 20 percent less
 energy than a typical Supercenter. In addition to the cutting-edge
 technologies already found in Wal-Mart stores, the new High-Efficiency
 stores will integrate industry-leading heating, cooling and refrigeration
 systems to conserve energy. High-Efficiency stores will help the retailer
 move one step closer to achieving its environmental goals, which include
 using less energy and producing less waste.
     "Just over a year ago, our CEO Lee Scott challenged our associates to
 open a store that was 25 to 30 percent more efficient by 2009," said John
 Menzer, vice chairman, Wal-Mart Stores. "The Kansas City High-Efficiency
 store is the first of its kind, and shows Wal-Mart is capable of operating
 stores, clubs and distribution centers in a way that saves energy, lowers
 utility costs, reduces emissions, and above all, provides a better shopping
 experience for our customers."
     In 2005, Wal-Mart opened two experimental stores in McKinney, Texas,
 and Aurora, Colo., to test several different environmentally friendly
 technologies, ranging from wind power to pervious pavement, from waterless
 urinals to light-emitting diodes. The aim was to experiment with innovative
 technologies, with the intention that they could some day be incorporated
 into a store prototype. The Kansas City High-Efficiency store is the first
 store to bring some of these experiments from the preliminary testing phase
 to a practical trial phase. Wal-Mart plans to open the next High-Efficiency
 store in Rockton, Ill., this spring.
     "We are learning a tremendous amount from our experimental stores,"
 said Eric Zorn, president, Wal-Mart Realty. "Wal-Mart stores are already
 some of the most energy-efficient in the retail industry, but we want to
 take efficiency even further. This new Supercenter is where we really get
 to put what we've learned into practice, and we're excited to reach a 20
 percent energy reduction so quickly."
     To achieve the 20 percent energy reduction at the new Kansas City High-
 Efficiency store, the company will target two main energy-consuming units:
 the heating and air conditioning system (HVAC), and the refrigeration
 system. With the installation of special equipment, such as a water source
 heat pump and cooling towers, hot and cold water can be harnessed to drive
 new levels of efficiency. Specifically, the new HVAC and more efficient
 refrigeration systems are fully integrated so that 100 percent of the heat
 rejected by the refrigeration system is reclaimed into the HVAC. The
 reclaimed heat is then converted into usable energy. By incorporating a
 loop-piping design, the advanced refrigeration system also reduces the
 amount of installed copper and the total refrigerant charge required.
     "For years, retailers have used air cooled equipment for air
 conditioning and refrigeration," Vice President of Prototype and New Format
 Design Charles Zimmerman said. "In recognizing that water has four times
 the heat carrying capacity of air, we realized it would be much more
 efficient as a conductor of energy in our heating, cooling and
 refrigeration systems. In this High- Efficiency store, we're putting that
 to the test by utilizing our on-site resources to full capacity before
 applying secondary power sources."
     Other energy-saving technologies in the High-Efficiency store include
 the installation of ultra-efficient case fans, glass doors on medium
 temperature grocery cases, RollSeal(R) quick response doors to seal air in
 areas such as the Garden Center, and a top-of-the-line dehumidification
 system. The store will also have a daylight harvesting system, which uses
 skylights to refract daylight throughout the store and light sensors to
 monitor the amount of natural light available. During periods of higher
 natural daylight, the system then dims or turns off the store lights when
 they aren't needed, thereby reducing energy-usage.
     Like many other Wal-Mart stores opening this month, the Kansas City
 Supercenter also features GE's energy-saving light-emitting diode (LED)
 refrigerated case lighting. LEDs have a longer life span than fluorescent
 bulbs, produce less heat and use significantly less energy than typical
 grocery case lighting. In the High-Efficiency store, motion sensor-driven
 LED lights have been installed in all freezer and medium-temperature
 refrigerated cases. When not in use for a few seconds, the lights in these
 cases automatically turn off, and quickly turn back on when a customer
 approaches. This direct learning from the Aurora and McKinney experimental
 stores is expected to add a 2 to 3 percent energy reduction, and will be
 rolled-out in new Wal-Mart stores, Supercenters, Neighborhood Markets and
 Sam's Clubs beginning this month.
     "We're very excited to launch this High-Efficiency concept in Kansas
 City, where our residents and local business leaders have shown that the
 environment is a key priority for them," said Dan Steele, Wal-Mart store
 manager. "Though most of the energy-saving technologies here are not
 visible to the public, we've added new signage to show our customers how
 these systems can help save money and keep our prices low."
     Lighting the Way for Energy Savings in Kansas City
     In addition to the focus on energy-efficient stores, Wal-Mart is
 committed to selling products that sustain our resources and our
 environment. As part of this store's grand opening events, Wal-Mart
 announces a partnership with Kansas City Mayor Kay Barnes to support the
 city's "A Million Lights Campaign." With its donation of 21,000 compact
 fluorescent light bulbs (CFLs), Wal-Mart will aid the city's campaign to
 distribute CFLs to low-income and senior citizen households in Kansas City,
 Mo. The Wal-Mart gift will also help the city reach its goal to change one
 million incandescent bulbs to energy-saving CFLs by October 2007. This
 in-kind donation of more than $53,000 brings this store's total grand
 opening donations to local charities and organizations -- such as the
 Kansas City Weatherization Improvement Project, Bridging the Gap, and the
 Boys Club of Greater Kansas City -- to $110,000.
