1. McDonough Bolyard Peck Educational Series HVAC Commissioning Presented by: Doug Wren Steve Baxter September 30, 2003

2. HVAC Commissioning  What is Commissioning  Benefits of Commissioning  HVAC Commissioning Design Construction Acceptance

3. What is Commissioning  ASHRAE Guideline 1-1996.  The PROCESS of ensuring that systems are designed, installed, functionally tested, and capable of being operated and maintained to perform in conformity with the design intent… it begins with planning and includes design, construction, start-up, acceptance and training, and can be applied throughout the life of the building.

4. Terminology  Commissioning Authority or Agent (CA)  The designated person, company, or agent who implements the commissioning process. The CA does not test the equipment!!  The ROICC is the CA for the Navy

5. Terminology  Testing Contractor or Test and Balance Contractor (TAB)  The person, company, or agent responsible for testing the building systems to ensure the equipment is working at the specified operating condition.  TAB Contractor – A first tier sub !

6. Terminology  Commissioning Team  Made up of the CA, CM, Design Engineer, GC, Mechanical Contractor, TAB, Electrical Contractor, Control Contractor, Owner’s Maintenance Personnel.

7. Benefits of Commissioning  Why is Commissioning Important? Systems are more complicated Costs are going up and customer satisfaction is going down in large part because HVAC systems don’t work as anticipated.

8. Benefits of Commissioning  Lower Life Cycle Costs  Lower Maintenance Costs  Reduced Trouble Calls  Reduced Manpower Requirements  Increased Customer Satisfaction  Reduction in Failure of Capital Equipment

9. Customer Integration Ideally, done throughout the entire Commissioning Process. Integrated and Coordinated with the Contractor’s Specified Training Requirements. Ensure information is available to allow maintenance personnel to develop maintenance programs.

10. Design Phase Include Commissioning Specification, update through each phase of design: Schematic, Design Development, and Construction Documents. Include Commissioning Plan in Specifications Include the Requirement for a Commissioning Schedule

11. Design Phase Applicable Specification Sections 01200N – Price & Payment Procedures 01310N – Administrative Requirements 15901 - DALT 15950 – HVAC Testing/Adjusting/Balancing 15995 – HVAC Commissioning

12. Design Phase  Understand the Basics of the Designed System and how it works with the Owner’s Expectations.

13. Ensure the design engineers have included the users’ (owner and maintenance staff) needs within the design intent document.  How does the Owner intend to Use the Space?  What Level of Control Does the Owner Anticipate for the Users.  What Level of Equipment is the Staff Trained on and Familiar with.  What does the Maintenance Staff Anticipate for Controls. Design Phase

14. Construction Phase Typical Failures Incorrect Programming Incorrect Power Wiring Incorrect Control Wiring Incorrect O/Ms & As-builts Inadequate Operational Design Mixing and Matching of Equipment and Controls

15. Construction Phase  KTR Responsibilities Commissioning Plan - (G)-Approved Commissioning Schedule – (G)-Approved  Include in specs under submittals and schedule. Periodic Commissioning Meetings

16. Construction Phase  CA Responsibilities Installation Observation Building Automation Testing  “100% Point to Point Verification”. Testing Adjusting and Balancing Review (Pre-Balance Meeting) Start Up Observation and Inspection

17. Construction Phase  Submittals complete and submitted prior to commissioning for ROICC to review.  Documentation  As Built Documents  O&M Manuals  TAB(S) Reports (S) – Start-up Report  Commissioning Report

18.  Limit KTR Initiated Substitutions  Only The AE Approves Substitutions  Ensure Documentation is Updated Schedule Submittals Changes in the Contract Documents Regular Update Meetings. Construction Phase

19.  During the Precon meeting make sure everyone has a clear understanding of the project goals and the requirement for a commissioning schedule.  Make sure everyone is in agreement on the amount of access the CA will have to the equipment. Construction Phase

20.  When Reviewing the Site Installation, Try to View Through the Eyes of the Maintenance Personnel.  Keep Maintenance Personnel Involved to Get their Input and to Keep Them with a Sense of Ownership.  Review Coordination Drawings for Clearances Construction Phase

21. Acceptance Phase  Point to Point Testing  TAB Accuracy Verification  Control System Function  Intersystem Functions  Functional Testing

22. Acceptance Phase  Deficiency Reporting and Corrections  Certificate of Readiness to Begin Functional Testing  Verification Report Final Test Reports Final Deficiency List

23. Acceptance Phase  Functional Performance Testing The ability of the system to produce the effect in accordance with the final design intent.  Recommendation of Final Acceptance

24. Make Sure the TAB Contractor has the Appropriate Amount of Schedule Time to do a Complete Job. Get the Close Out Documents Started as Early as Possible, O&M’s, As-Builts, Etc. Make Sure Everyone is Clear on the Commissioning Schedule and Milestone Dates are Met Prior to the CA being on Site for an Event Such as Start-up of Equipment. Acceptance Phase

25.  The Two Most Important Tasks in the Final Phase of Commissioning: Training Documentation Acceptance Phase
