Calgon Carbon Relocates New Headquarters

• Combining Headquarters with R&D Center
• Reduced overall square footage by 22,000 SF

The new Calgon Carbon headquarters

Calgon Carbon Corporation (CCC: NYSE), an environmental technology company headquartered in Pittsburgh, announced today that it has officially moved its world headquarters to the newly constructed, Westpointe Corporate Center Four in Moon Township, PA.

Calgon Carbon has entered a 15-year lease with DiCicco Development to occupy 75,566 sq. ft of the 130,000 sq. ft. building. Approximately 200 of the company’s executive staff, sales, and service employees made the move in early February. The research and development laboratory, which will be known as the Innovation Center, will be completed later this year. By consolidating the headquarters with its laboratory, Calgon Carbon will reduce its office square footage by approximately 22,000. The building is expected to qualify for LEED certification in the Gold category.

In addition to the corporate staff and R&D, the new headquarters will be home to Calgon Carbon’s Industrial, Municipal and Specialty business units. The Ultraviolet Technologies division, including Hyde Marine® Ballast Water Management Technology, will continue to reside in McClaren Woods business park, also in Moon Township.

“This headquarters represents a new chapter for Calgon Carbon,” said Randy Dearth, Chairman, President and CEO, Calgon Carbon. “We’ve transformed this company over the past two years and this new location is a great fit for the footprint of our company.”

The design of the building focuses on open workspaces that emphasize collaboration. Gretchen Barlett, of Barlett Design, an architecture and interior design firm, worked closely with DiCicco Development and Randy Dearth to achieve a progressive corporate environment that encourages frequent employee interaction.

“Randy is a big proponent of open-door work settings. He wanted the design of the building to support coworker interaction.” With that direction, Gretchen designed multiple areas where employees could catch up with each other outside of traditional conference rooms or offices. Collaboration spaces feature dry erase walls and café-style island counters – ideal for working through ideas that could otherwise get stifled in traditional conference rooms.

Consistent with Calgon Carbon’s commitment to sustainability, the building features the use of photovoltaic solar power, energy saving occupancy sensor lighting controls, a high-efficiency zone heating and cooling system, a living vegetation roof, and ergonomic workstations with access to daylight.
