Building commissioning is a systematic process that ensures building systems function as intended throughout their operational life, utilizing a total quality management approach to reduce costs and improve performance. It involves pre-functional checklists, functional testing, and the creation of comprehensive documentation, aiming to enhance coordination, training, and the operational efficiency of the building. Overall, commissioning contributes to higher quality buildings, cost savings, and improved productivity while incurring a percentage of the overall construction costs.

1. Building Commissioning

2. Building Commissioning The systematic process of ensuring that building systems (e.g. HVAC, lighting, etc.) are designed, built, and operated as intended (and/or as necessary for current use). 1 A total quality management (TQM) approach to the building construction process, where enforced processes lead to overall reduced costs and better performance. 2 Source: NEMI Retro-commissioning Existing Building Inventory, February 2002, by FMI.

3. Pre-functional Checklist Static inspection and procedures that confirm that the systems and equipment are ready for initial operation Created by the Commissioning Agent and Design team during the design phase Completed by Contractors before Functional Testing is started.

4. Functional Test Dynamic testing of systems and equipment, under operating conditions, to demonstrate compliance and design intent Tests sequences of operation, responses and interlocks with other systems Created by the Commissioning Agent during the Design Phase and sometimes modified during construction Performed by contractors, witnessed and documented by Commissioning Agent during Construction phase

6. Positive Impacts of CX Better coordination between consultants Smoother start-up and turn-over by contractors Facilities Management better trained to provide safe, comfortable, productive environment. Building less expensive and easier to operate Not only do you have a better understanding of the project goals from inception…. But you hold these goals as a standard for the building well into it’s operating life! Facilitates Future Changes

7. Benefits of CX Higher quality product leads to better reputations. Cost savings. Especially operating and energy cost savings! Less Litigation Healthy buildings that improve productivity.

8. Commissioning Costs New Construction 0.5 to 3.0% of the overall construction cost Design phase efforts 0.1 to 0.5% of the total overall construction costs Construction Phase Efforts HVAC and Controls 1.0 to 2.0% of the total mechanical costs Electrical 1.0 to 2.0% of the total electrical costs Does not include infrared scanning/power quality/switchgear testing
