New Building Commissioning Cx
Building commissioning ensures that any new building begins its life cycle at optimal productivity, comfort and safety, while improving energy efficiency. It facilitates and ensures the required communication, coordination, testing and verification and results for the delivery for all critical building systems take place. Effective commissioning is an intentional, visible, cooperative and proactive process. It includes design review, installation verification, system start-ups, functional performance tests, operations and maintenance training, and complete documentation of all essential building systems. Post construction, it will enable the building maintenance staff to have the baseline requirement for continued optimum building systems performance throughout a facility’s existence.
Re- and Retro Commissioning RCx
Re-commissioning is the process through which buildings are commissioned at some time after their initial completion and occupancy. Re-commissioning is a check to ensure that building systems are still functioning as originally designed and to identify where periodic operating procedure changes, control system failures or changes in use have affected building systems performance in a previously commissioned building. Closely related to re-commissioning is retro-commissioning which is the commissioning of a building that has not been commissioned at the time of construction. Retro- commissioning may also include proposing and implementing alterations to the existing building systems.
Monitor based Commissioning MBCx
A process to improve the operation of buildings with an emphasis on using meter-level or system-level data analysis to identify opportunities for improvements The MBCx process may include initially bringing the building systems up to the owner’s operating requirements through an existing building commissioning process, then performing ongoing commissioning to identify and correct degraded performance over time.
