VIRGINIA POWER REDUCING ENERGY USE AT CORPORATE OFFICES

 VIRGINIA POWER REDUCING ENERGY USE AT CORPORATE OFFICES
 RICHMOND, Va., May 22 /PRNewswire/ -- The drive is on across America


to reduce energy use and conserve. In your home, that might include switching from incandescent to fluorescent lighting, making sure heating and air conditioning systems are serviced regularly and installing low-flow water faucets.
 But what if your "home" is a total of 26 floors filled with 2,800 people, more than 20,000 light bulbs, 4,000 tons of heating and cooling equipment and 57 bathrooms with 175 water faucets?
 Similar conservation steps can be taken -- albeit on a grander scale with much grander results.
 Virginia Power began looking for new ways to reduce waste and conserve energy in its operations in 1986 as part of its cost-reduction efforts. Today, at its two largest Richmond offices, the company is saving more than 5 million kilowatt-hours of electricity annually -- or enough electricity to power the homes of more than 440 typical customers for one year.
 "At a time when Virginia Power is beginning new conservation programs for its customers it's only fitting that we are actively engaged in reducing our electricity needs," said John A. Ahladas, senior vice president-Corporate Services. "It serves as an example for others and also helps us control our costs."
 One of the most recent energy-saving measures is high-tech, yet as simple as putting a day-night sensor on an outdoor security fixture. The company is installing light sensors on the east and south faces of its downtown Richmond corporate office to cut off the perimeter indoor lights during periods of strong sunlight. Annual consumption of electricity will be reduced by as much as 80,730 kwh and $5,650 will be saved each year.
 One of the largest single projects began six years ago. As each of 20,000 40-watt fluorescent tubes began to burn out, each was replaced with 34-watt fluorescent tubes. Today, that change alone reduces annual consumption by 491,400 kwh and yearly costs by $34,400.
 The Innsbrook Technical Center just west of Richmond, which opened in 1987, was scheduled to use the standard 40-watt fluorescent tubes, but the company opted for the 34-watt tubes based on successful tests at the downtown location. Savings achieved are 341,250 kwh and $23,890 per year.
 All in all, the company is expecting completed or currently planned conservation measures at its two largest offices to reduce annual electricity consumption by 5.28 million kilowatt-hours and annual expenditures by $372,000. Many of the energy-saving suggestions came from employee-led teams challenged to find ways the company can minimize waste.
 Other conservation steps that have been taken at the downtown Richmond location include:
 -- Replacing the older motors in the heating and cooling system with energy-efficient motors and variable speed motor controllers. Expected annual savings are 1.5 million kwh of electricity and $103,340.
 -- Lowering the temperature on three of the four water heaters from 150 degrees to 130 degrees (the fourth water heater is used solely for the cafeteria's dishwasher and is set to comply with health department requirements). Annual savings are 56,160 kwh of electricity and $3,930.
 -- Installing low-flow aeration nozzles on all 138 restroom faucets in 46 restrooms, reducing flow from 3.75 gallons to 0.5 gallons per minute. Water savings are 6,000 gallons annually and electricity savings are between 2,000 kwh and 6,000 kwh per year because of the reduced use of hot water.
 -- Replacing the magnetic ballasts in fluorescent lighting with electronic ballasts. This will be done as the magnetic ballasts need replacement. Expected annual savings are 996,840 kwh of electricity and $69,780.
 The newer Innsbrook Technical Center had many energy-savings features designed intro it, including low-flow water faucet aerators. But even since it opened, other energy-saving steps have either been completed or are underway, such as:
 -- Rotating the lighting pattern based on usage patterns. Expected annual savings are 741,810 kwh of electricity and $51,930.
 -- Installing variable speed motor drives on the two main cooling towers. Expected annual savings are 99,120 kwh of electricity and $6,940.
