What is Building Commissioning ?
The basic purpose of building commissioning is to provide documented confirmation that building systems function in compliance with criteria set forth in the Project Documents to satisfy the owner’s operational needs.
Building Commissioning Explained :
The basic purpose of building commissioning is to provide documented confirmation that building systems function in compliance with criteria set forth in the Project Documents to satisfy the owner’s operational needs.
Commissioning is the process through which building systems are verified for operation and performance. Any deficiencies in operation or performance are noted to the design and construction teams for corrective action. Traditionally this function was fulfilled by the individual subcontractors. Due to the complexity of present and future building designs, particularly in the field of EMCS (Energy Management Control Systems) and Life Safety systems, a coordinated effort in commissioning of these multi-discipline systems is an asset to confirming the building’s performance to the owner.
Retro-Commissioning (RCx)- In existing, un-commissioned buildings
Commissioning of existing systems may require the development of new functional criteria in order to address the owner’s current systems performance requirements
Commissioning for Existing Buildings is a systematic process for investigating, analyzing, and optimizing the performance of building systems by improving their operation and maintenance to ensure their continued performance over time. This process helps make the building systems perform interactively to meet the owner’s current facility requirements.
Re-Commissioning:
The periodic re-implementation of the commissioning process, either on a regularly occurring schedule (every 3 to 5 years is typical), or if building performance degrades, or if the building occupancy or usage changes significantly.
Ongoing Commissioning:
The application of commissioning related process activities on an ongoing or continuous basis to ensure that the CFR are being met and to support the continuous improvement of system performance. The Ongoing Commissioning Plan details how these activities and goals will be achieved.
Continuous Commissioning:
The Continuous Commissioning Process focuses on optimizing HVAC system operation and control for existing buildings through monitoring and engineering analysis of mechanical systems and occupant needs.
