  • 3. COMMISSIONING FRAMEWORK
  • 4. Total Building Commissioning Process ASHRAE Guideline 0-2005: The Commissioning Process (Used as a foundation for ASHRAE Guideline 1, NIBS Guideline 3, and other Total Building Commissioning Process technical guidelines Guidelines 2-200X & 4-200X ASHRAE Guideline 1-2007: NIBS Guideline 3-2006: through 14-200X: Technical HVAC&R Technical Exterior Enclosure Technical commissioning guidelines Requirements for the Requirements for the dealing with structure, Commissioning Process Commissioning Process electrical, lighting, interiors, plumbing, etc.
  • 5. ASHRAE Guideline 0-2005 Defines the process Generic: any system or discipline ASHRAE Guideline 1.1-2007 How to apply the process to HVAC&R Several annexes/examples ASHRAE/NIBS Guideline 3 How to apply the process to enclosure elements Walls, floors, roofs, fenestration Several annexes/examples
  • 6. Total building Commissioning (Cx) guidelines are in the works: Guideline X Plumbing (ASPE) Guideline Y Lighting (IESNA) Guideline 1.2 Existing HVAC&R (ASHRAE) Guideline 1.3 Operator Training (ASHRAE) This presentation will focus on ASHRAE Guideline 0-2005 and the overall Cx Process
  • 7. COMMISSIONING DEFINED
  • 8. An ongoing & structured quality assurance process (ideally spanning from pre- design into occupancy) that ensures continual: Communication Documentation Verification In simplest terms, commissioning is intended to ensure a building meets the owners requirements upon turnover It is NOT: An event A short term task Punch list clearance It is a Team sportfor successful commissioning, everyone must buy in to and participate in the process
  • 9. A quality-focused process for enhancing the delivery of a project. The process focuses upon verifying and documenting that the facility and all of its systems and assemblies are planned, designed, installed, tested, operated, and maintained to meet the Owners Project Requirements (OPR). * ASHRAE Guideline 0-2005: 4. Definitions
  • 10. The OPR document explicitly calls out the minimum characteristics that will define a successful project from the owners perspective Must address quality as well as quantity Must include verifiable benchmarks (criteria) OPR is completed during pre-design This document becomes the basis for all commissioning verification effortsand is thus critical to a successful commissioning outcome
  • 11. 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. The Commissioning Team uses methods and tools to verify that the project is achieving the Owners Project Requirements throughout the delivery of the project. The Commissioning Process assumes that owners, programmers, designers, contractors, commissioning team members, and operations and maintenance entities are fully accountable for the quality of their work.
  • 12. COMMISSIONING PROCESS PRE-DESIGN PHASE
  • 13. Develop the Owners Project Requirements (OPR) Review lessons from previous projects Identify Cx scope and budget Develop initial Cx Plan Owner acceptance of pre-design Cx activities * ASHRAE Guideline 0-2005: 6.1.2 Objectives
  • 14. To get the process off on the right foot Ensure development of a thorough OPR document
  • 15. The Commissioning Authority (CxA) The Cx Team Pre-Design Cx Documents
  • 16. The Commissioning Authority (CxA) The Cx Team Pre-Design Cx Documents
  • 17. Authority (or Provider) versus Agent An authority acts for the owner An agent can act as the owner (NOT intended) Professional services contract must spell out roles and responsibilities for this crucial partyincluding scope of work to be conducted (which can vary greatly) CxA may be: An independent entity Owners in-house staff THE CXA WILL NOT SINGLE-HANDEDLY COMMISSION A PROJECT
  • 18. Should have actual and perceived independence of action (an unbiased party) Should have a background and experience to match project expectations Will act in the best interests of the owner Will interact with owners representatives, the design team, the contractor and subcontractors Will lead the Cx Team and team meetings Should have outstanding people skills
  • 19. The Commissioning Authority (CxA) The Commissioning Team Pre-Design Cx Documents
  • 20. Includes many members: CxA Programming Consultants Owners representatives Users Maintenance Staff Design Team representatives Contractor representatives (if possible) Members (numbers and bodies) will change from phase to phase
  • 21. The team is led by the CxA The team will complete a variety of tasks Specific pre-design roles and responsibilities will vary from project to project Responsibility for team members must be clearly allocated and contractually assigned
  • 22. The Commissioning Authority (CxA) The Commissioning Team Pre-Design Cx Documents
  • 23. OPR Cx/design service contract integration Cx Plan Issues Log Systems Manual
