Cx is a Quality Assurance Process for Buildings. From pre-design through design, construction, and building operations, it involves achieving, verifying, and documenting the performance of each system and integrated system. Systems meet the building's operational needs within the capabilities of the documented design and equipment capacities, in accordance with the owner's functional criteria (ASHRAE Guideline 0).
Commissioning Processes includes:
- Documenting the Owner’s Needs
- Documenting Design Teams Reasoning and Decisions
- Conducting Quality Peer Reviews
- Defining, Specifying, Planning and Verifying the Functional Testing of the Building Systems
- Increased Coordination and Integration of Construction Trades
- Preparing and Enhancing Building Documentation
- Improving the Operation and Maintenance Training Process
- Post Construction and Pre Occupancy, including systems start up, testing and troubleshooting, systems balancing and Integration, building Systems Operation, building Systems verification of Owners Requirements and Design Specifications compliance, systems training
- Turn over an Operable building that meets the customer requirements and Contract Documents. The result should be fully functional systems that can be properly operated and maintained throughout the life of the building. (ASHRAE, 2004)
- Post occupancy inspection (seasonal fluctuations)
