Retro-Commissioning

Retro Commissioning Definition

Retro-Commissioning is the application of the same process to existing buildings. Retro-commissioning is a process that seeks to improve how building equipment and systems are operating and functioning together. Depending on the age of the building, retro-commissioning can often resolve problems that occurred during design or construction, or address problems that have developed throughout the building’s life. In all, retro-commissioning improves a building’s operations and maintenance (O&M) procedures to enhance overall building performance. 

It is a collaborative process that looks at how and why building systems are operated and maintained. It then identifies ways to improve overall building performance.

  • A systematic process for improving and/or optimizing an existing building’s operation and energy consumption profile.
  • An adaptive process that meets the current operational needs as closely as possible.
  • The process may include remedial design and construction to accomplish this goal. /li>

About

Building Commissioning is the process of verifying that owner’s project requirements for design, construction, performance, maintenance, and equipment lifecycle are met. Building commissioning is a quality-focused process necessary for both non-complex and complex construction projects. The ultimate goal of the commissioning process is to deliver for the owner a project that has reduced first cost of delivery, substantial life cost reductions, fit for intended use and meets the needs of users and occupants.
