Two Liberty Place
High Rise Central Utilities Plant Retrofit Results in 47% Energy Reduction! New Chiller Plant Without Helicopters or Cranes
The project consisted of replacing 2,000 tons of chillers with new high-efficiency chillers, new fiberglass modular cooling towers, upgraded BACnet controls, a 1,000-ton plate and frame heat exchanger for free cooling in the winter, and a dynamic chiller plant optimization software package to modulate the chillers, pumps, cooling tower and valves automatically based on demand!

HOW WE DID THIS:
Ready to start a conversation with someone who has a background on this project?
Built in 1990 as one of the first class “A” high rises in downtown Philadelphia, Two Liberty Place is a 57-story iconic multi-use skyscraper. The building consists of 30 floors of Class A office space, 20+ floors of luxury condominiums, an upscale restaurant, retail shops and food court.
- 25-year-old chiller plant was failing on the 38th floor.
- Dense build out of downtown area prohibited a helicopter lift or crane to access the 38th floor.
- Building was not designed for freight elevators or rigging paths to accommodate major mechanical equipment replacement.
- Concord provided innovative HVAC and electrical engineering to utilize modularized equipment and assembled in place using a unique “Lego” type stacking solution.
- Along with our partner Rich Energy Solutions (RES), the team performed complex rigging analysis to transport the chiller/cooling tower components through retail spaces and in small freight elevators up to the 38th floor.
- The project was finished without any disruption to the residents, office, and retail tenants.
- The building’s thermal plant is saving approximately 47% in energy usage.
- Qualified for a Philadelphia Electric Company (PECO) custom incentive and received a significant rebate from their commercial incentive program.
