Commissioning and Recommissioning Process
The commissioning process is a methodical quality-focused approach aimed at ensuring that all components, systems, and assemblies within a facility are properly planned, designed, installed, tested, operated, and maintained to meet the owner's project requirements. Recommissioning refers to repeating the commissioning process for a project that has already undergone commissioning, typically after several years of operation (Poulos, 2007). Depending on the specific case, additional commissioning activities may be required, but the primary objective remains to ensure the proper execution of both commissioning and recommissioning efforts.

Types of commissioning activities involve different building scenarios
Recommissioning is a critical post-construction process that should be performed approximately 5 to 7 years after the initial commissioning. The need for recommissioning may be indicated by signs such as electromechanical inefficiencies and increased utility costs. If left unaddressed, these inefficiencies can escalate into more severe system-wide issues. Common indicators that necessitate recommissioning include cold drafts, equipment running excessively, thermal imbalances, lighting inconsistencies, poor indoor air quality, and overall reduced occupant comfort (Poulos, 2007; Stocke, 2018).
The benefits of both commissioning and recommissioning are significant, with energy savings being one of the most substantial incentives. A well-executed commissioning and recommissioning process ensures that the facility's components are optimized according to the owner's specifications. This process contributes to the longevity of equipment, optimal performance, and improved occupant health and productivity, as well as maintaining superior indoor air quality. Furthermore, commissioning and recommissioning are essential steps toward achieving LEED Certification points, reinforcing their importance in sustainable building practices (Poulos, 2007; Stocke, 2018).
