Highwoods Properties: PPG Place

Solutions

Highwoods began by overhauling the plaza at the center of PPG Place, upgrading the summer water feature with new jets and LED lights that shine through the water. The ice rink expanded 20% from 9,364 square feet to more than 12,000 square feet, making it larger than New York City’s Rockefeller Center. The renovations included new chillers, controls, and pumping systems.

To improve overall operations of the complex, Highwoods:

Reengineered the chilled water systems, adding 9 new high-efficiency chillers and reworking the pumping scheme for One PPG
Replaced original pneumatic building controls with a modern direct digital control (DDC) system
Added a heat pump system at the PPG Wintergarden that utilizes waste heat from the PPG Ice Rink’s ice chillers
Installed high-efficiency LED lighting
Replaced restroom fixtures with low-flow, touchless fixtures
Upgraded elevator controls to an efficient destination dispatch system
Installed Variable Speed Drive systems
Replaced roofing with high solar reflectivity roofs
Implemented green cleaning and recycling solutions

Since Highwoods purchased PPG Place, ice rink attendance has increased 25%, and building occupancy has increased from 88% to 95%. In that same time period, system upgrades and monitoring by the company’s Energy Command Center have decreased energy consumption by 29% percent and water consumption by 24%. Energy cost savings amounted to over $950,000.
