Retrocommissioning Process
The retrocommissioning process on the Urbana-Champaign campus is focused on reviewing and improving building mechanical systems, while maintaining or improving occupant comfort.
Overview
Engineers undertake a thorough investigation of available building documentation, energy usage history and similar pertinent data
Field technicians and tradesmen gather data regarding operating conditions, sensor accuracy, equipment condition, and historic maintenance data in addition to conducting informal client interviews
The composite teams discuss findings and then look to restore mechanical systems to their original design while implementing energy saving improvements
The teams take the lead in making small changes and recommending larger capital projects, which require more funding, to Engineering or Maintenance to augment and sustain the building's energy saving strategies
Building system control experts implement modern methods of control, monitor energy usage after changes, review actual metered data, and verify the savings
