The importance of retro-commissioning

Retro-commissioning (RCx), or existing building commissioning, is a systematic process developed to evaluate, document, and improve the operation of base building systems. Applying a comprehensive RCx process can be a cost-effective way to identify and implement measures to reduce energy use and cost while improving maintenance and occupant comfort in existing buildings.

How retro-commissioning can help your building

RCx may solve problems related to the original design and building construction or uncover issues that were created during operational changes, upgrades and tenant improvements. The retro-commission necessity, modifications and process vary for every facility.

UL’s RCx services

UL can conduct a feasibility study to determine which facilities are best suited to undergo an RCx effort, and to what level. Identifying those buildings with greater opportunities allows property owners/portfolio managers to make educated business decisions on how best to allocate financial resources.

What you can expect from UL’s RCx services

  • Methodical and detailed functional performance test procedures
  • Identification of deficiencies, system issues and areas for improvement
  • Building automation system (BAS) trend analysis
  • Stand-alone data logging
