PWG1960403-4-5-7, PWG992803, PWG297549 - Retro-Commissioning Assessment Studies

Retro-Commissioning is the application of the commissioning process to existing buildings. Retro-Commissioning is a systematic process for investigation, identifying and implementing operational and maintenance improvements to existing buildings and for ensuring their continued performance over time. This optimization is generally achieved by implementing energy, demand, operation and maintenance costs reducing measures identified in the investigation phase of the process. The main goals and objectives of the Retro-Commissioning process are to ensure; the building is performing as efficiently as possible and as expected; to improve and optimize the equipment and systems operations and performances; and to improve and optimize how the systems function together, while meeting the current owners and operations requirements.
