The Plaza at PPL Center has joined a very short list of buildings nationwide by receiving a prestigious environmental award for its "green" features.

The Leadership in Energy and Environmental Design (LEED) program of the U.S. Green Building Council has awarded the building a "gold" rating. The Plaza is the first privately owned building in Pennsylvania to achieve this status, and only the eighth privately owned building in the nation to win this coveted award.

"This building's environmentally friendly and cost-effective features save water and energy, minimize the building's impact on the environment and make it a pleasant and healthy place to work," said William F. Hecht, chairman, president and chief executive officer of PPL Corporation. "We're pleased that the U.S. Green Building Council has recognized this achievement."

  Among the environmental features of the building are:

  -- Extensive use of natural daylight that reduces the dependency on
     electric lighting and provides a direct window view for more than
     90 percent of the office space.
  -- Two plant-filled winter gardens that provide a buffer from direct
     southern exposure and improve indoor air quality.
  -- A very efficient heating, ventilating and air conditioning system that
     uses more than 30 percent less energy than conventional building
     standards.  It includes an ice storage system that makes ice at night
     when electricity demand is low and uses the ice to help save cooling
     energy during peak daytime periods.
  -- Bicycle storage, showers and locker rooms for employees who bike to
     work.
  -- An advanced lighting control system that dims the lights when there is
     natural daylight available and turns off lights in unoccupied areas.
  -- A vegetative roof to reduce runoff, reduce energy consumption and
     extend the life of the roof.
  -- Water-conserving devices that save at least 500,000 gallons of water
     per year.
  -- A large street plaza to increase open space for downtown.
  -- Recycled materials used in construction, and recycling of construction
     debris.
  -- The urban site used existing infrastructure and allows access to public
     transportation.
  -- Electricity provided from renewable sources.
  -- Storm water runoff control features.
  -- Fresh air ventilation, an air filtration system and careful selection
     of building materials to provide high indoor air quality.

"Our collective focus was to create a 'green' building that would provide tenants and the community at large with an attractive, comfortable and environmentally responsible place to work and visit," said William P. Hankowsky, chief executive officer of Liberty Property Trust. "Our team worked closely with PPL and Robert A.M. Stern Architects to ensure that the vision always remained on track as the building rose from plans to reality."

Liberty is the developer and owner of the building, and PPL leases six of its eight floors. The Plaza, completed in spring 2003, houses PPL's unregulated subsidiaries including PPL Generation, PPL EnergyPlus and PPL Global.

LEED is a voluntary green building rating system that defines, measures and certifies buildings that are environmentally responsible, economically efficient and healthy places to live and work. The LEED certification process includes a thorough review of the building's design features, construction plans and records.

The Plaza at PPL Center received two other awards recently for its environmental features. It was named one of the 10 best examples of architectural and green design solutions that integrate architecture, technology and natural systems by the American Institute of Architects, and it won first prize in the large building workplace category of the Northeast Green Building Awards sponsored by the Massachusetts Technology Collaborative Renewable Energy Trust and the Northeast Sustainable Energy Association.
