Smart Building Strategies
Building Retro-commissioning is an important process for existing buildings that seeks to improve building systems function. Process can often address problems that have developed throughout the building's life. Retro-commissioning improves building operations and maintenance (O&M) procedures to enhance overall building performance.
Commissioning process is a highly effective method to improve the performance of building systems and equipment. The U.S. Green Building Council has recognized the effectiveness and benefits that commissioning process provides in green buildings, and has incorporated commissioning in the LEED™ rating systems. For existing building, LEED™ has defined following items in the existing building rating system:
Commissioning of existing buildings or “Retro-Commissioning,” is a systematic process applied to existing buildings for identifying and implementing operational and maintenance improvements and for ensuring continued performance and efficiency over time. Retro-commissioning is a process that not only intends to optimize building system operation but also ensures systems are functioning together
Implementation of retro-commissioning may recommend capital improvements, but the primary focus is on using O&M tune-up activities and diagnostic testing to optimize the building systems. Primary objective of existing building retro-commissioning is:
