2. What is Commissioning Why Commission Commissioning Process Benefits LEED & Commissioning Who Costs Commissioning

3. “The Commissioning Process is a quality-oriented process for achieving, verifying, and documenting that the performance of facilities, systems, and assemblies meets defined objectives and criteria.” -- ASHRAE Guideline 0-2005 Commissioning Defined

4. Commissioning – What is it? Term derived from Ship Building – A commissioned ship is one deemed ready for service. Material, systems and staff have successfully completed a thorough, quality assurance process.

5. Commissioning – What is it? Building undergoes an intensive quality assurance process that begins during design, continues through construction, occupancy and operation.

6. Commissioning – What It Does Commissioning produces a Building that: Meets the unique needs of its owner and occupants. Operates as efficiently as possible. Provides a safe, comfortable work environment. Operated and maintained by a well-trained staff or service contractor.

7. Commissioning Don’t I already pay for that?

8. Commissioning Design Professional Agreement No “third set of eyes” No Start Up / Operational Issues Minimal field experience Problems = Conflict Don’t I already pay for that?

9. Commissioning Construction Contract Craftsmen, not Engineers No formal Cx program No performance criteria No witnessed tests No Component Testing No Systems Testing Problems = Conflict Don’t I already pay for that?

10. Commissioning Why do we need Commissioning? “..yeah, they’re substantially complete, but…”

11. Commissioning Architect Elec. Contractor Mech. Contractor Elec. Engineer Mech Engineer General Contractor Typical Project Team Configuration Up to the Mid 1970’s

12. Commissioning Gaps between disciplines resulting in: Poor coordination Lost details Costly change orders Delays in schedule Typical Project Team Configuration After the Mid 1970’s

13. Commissioning Commissioning helps fill the gaps in coordination Commissioning Encompasses “All” New Project Team Configuration with Commissioning

14. The Commissioning Process The Commissioning Process involves steps that are integrated into every phase of the project: Commissioning is NOT just testing at the end! PRE-DESIGNDESIGNCONSTRUCTIONWARRANTYCOMMISSIONING

27. PRE-DESIGNDESIGNCONSTRUCTIONWARRANTYCOMMISSIONING The Commissioning Process Update Commissioning Plan & Schedule Review Submittals against Cx Plan, OPR, and BOD Review Control Sequences Develop Test Procedures Based on Control Sequences Review with Contractors/A/E

28. PRE-DESIGNDESIGNCONSTRUCTIONWARRANTYCOMMISSIONING The Commissioning Process Update Commissioning Plan & Schedule Review Submittals against Cx Plan, OPR, and BOD Review control sequences Develop test procedures Document construction observations Periodic Site Visits Regularly Scheduled Cx Meetings

29. PRE-DESIGNDESIGNCONSTRUCTIONWARRANTYCOMMISSIONING The Commissioning Process Update Commissioning Plan & Schedule Review Submittals against Cx Plan, OPR, and BOD Review control sequences Develop test procedures Document construction observations Develop Systems/O&M Manuals CxA Reviews for Completeness Concurrent with A/E Review

30. PRE-DESIGNDESIGNCONSTRUCTIONWARRANTYCOMMISSIONING The Commissioning Process Functional Performance Testing (FPT) Documentation of deficiencies found during FPT’s Deficiency correction and retesting Training of O&M Personnel Final Report

31. PRE-DESIGNDESIGNCONSTRUCTIONWARRANTYCOMMISSIONING The Commissioning Process Assist with maintenance management program Adjust for occupancy/warranty period Off-season testing Optional: Lessons-learned meeting Optional: Periodic re-commissioning

32. Commissioning HVAC Electrical Plumbing IT, Fire Alarm, BMS, Envelope Special Spaces Any Building System Systems Commissioned

33. Commissioning Sets clear measurable goals for everyone –Verifies owner’s requirements are being met throughout the design and construction phases Establishes accountability –Changes the way people perform –Allows designers and contractors to measure success as well as deficiency Benefits of Commissioning

34. Commissioning Quality Process Prevents/resolves problems Discovers/correct s design issues early in design Improves specifications & design documents Prioritizes systems for early completion Reduces RFI’s & change orders Benefits of Commissioning

35. Commissioning Contractors focus on quality work Improves submittal process Provides resource for MEP coordination prior to construction Catches problems at the start of installation Tests finished work to verify proper operability Interfaces builders with operators Timely delivery of Systems/O&M materials Creates team atmosphere and accountability Benefits of Commissioning

36. Commissioning Improves Energy performance Comfort Air quality Occupant productivity Equipment life Maintainability Facility staff preparedness Benefits of Commissioning

41. LEED ® & Commissioning Why does LEED require Commissioning? Improves: Energy performance Comfort Air quality Occupant productivity Equipment life Maintainability Facility staff preparedness

42. Commissioning Who is the Commissioning Authority?

43. Commissioning Who is the Commissioning Authority? Third Party Field Experience Engineering Background Project Management Project Experience Single vs Integrated Communicator LEED Requirements Not Under Contractor Can be on Design Team <50,000 sqft Can be in Design Firm > 50,000 sqft Cannot Perform Enhanced Cx

44. Commissioning Costs Different for Each Project Depends on Size, Complexity and Scope of Cx Accounts for Very Small Amount of Construction Budget Accounts for even Smaller Amount of Building’s Lifecycle Costs

45. Commissioning Costs Total Costs - $0.49 -$1.66/qft Average Equates to 5 Year Payback Value of Energy Savings - $0.02 - $0.19/sqft Value of Non-Energy Savings - $0.23 – $6.96/sqft 1 Commissioned Buildings have 8% – 20% savings in Operating Costs over Non-Commissioned Buildings 2
