Three PNC Plaza
3 PNC Plaza

In a new building, CJL Engineering's commissioning service includes a methodical quality assurance process designed to verify that building systems are fully operational and are performing interactively according to the design intent and owners requirements.


Retro-commissioning service is a process that identifies opportunities for improvement in existing buildings to optimize systems performance. An economic analysis of conservation opportunities identifies capital improvements required to lower operating and utility costs.


CJL Engineering provides LEED® Commissioning services for Three PNC Plaza (at left).  This $210 million mixed-use, 652,000 sq. ft, 23-story high-rise is located in downtown Pittsburgh.  The project has received the US Green Building Council LEED® Silver Certification.
