1 Commissioning National Training for Commissioning, 2006 Presented By Paul Sra and Mike Cavan 1

2 Scope of Presentation Commissioning overview Commissioning requirements for LEED Standard Roles and responsibilities of key persons for projects in regard to commissioning Commissioning process and its deliverables Case studies 2

3 What is Commissioning? ASHRAE defines the commissioning process as a quality oriented process for achieving, verifying and documenting that the perforamnce of facilities, systems and assemblies meet the defined objectives and criteria Commissioning is a quality assurance process where verification against design criteria is carried out, and ensures that adequate documention and O & M training has been provided. 3

4 What is Commissioning? A planned program of activities that advances the built works from the earliest stages of the Planning Phase to a condition of full operation, meeting all objectives of commissioning as defined by the client s functional program and the design intent. Commissioning is documenting for future operations. 4

5 Commissioning Requirements for LEED Standards For any LEED project, there are 6 fundamental Cx items that must be followed to attain LEED Certification; Engage a Cx Manager/Commissioning Authority Review Design Intent & other Design documentation. Include Cx requirements in Construction Specifications Develop & utilize a Cx Plan Verify installation, functional performance, training & Cx documentation Provide a final Cx report at the end of the project 5

6 Securing the Additional Commissioning Credit in The LEED System In addition to fundamental building Commissioning, an additional commissioning related point could be achieved: Commissioning Authority independent of the design team shall conduct a peer review of the design development, construction documents and contractor s submittals such as shop drawings. Provide a single manual containing all information required for re-commissioning the bldg. system Conduct a near end of warranty and plan to address occupant concerns 6

7 Why do we Commission? We Commission in order to provide a smooth transition from construction of the built works to an operational state. 7

8 Level /Extent of Commissioning In order to manage the cost and result of the commissioning process, owners must consider the following three basic questions: What systems should be commissioned What tasks should be completed in order to commission each system Who should be responsible for each task. Other factors: Type of project- new construction, fit-up, general purpose office, laboratory, Heritage Facility 8

9 Level/Extent of Commissioning (cont.) Complexity of project: Is it a Floor fit-up or Level 3 Lab - HVAC Containment / Fumehoods / Biological Safety Cabinets Profile of project LEED Certification 9

10 Commissioning of Total Building Systems Vertical Transportation Building Envelope Building Automation System (BAS) Integrated Mechanical & Electrical Electrical Distribution Facility Architectural Roof system, curtain wall system Integrated Security Life Safety Systems Indoor Environment Emergency Power Generation Heating & Cooling Plant 10

11 Benefits of Commissioning 1) Comprehensive understanding of Client s needs (such as functional and operational requirements) 2) Reduce tenant complaints and reduce O&M costs (by providing appropriate systems & equipment considering maintainability) 3)Indoor air quality parameters verified 4) Protection of health & safety of occupants (e.g. verification of Fire protection, life safety systems, security & operation of facility) 11

12 Objectives of Commissioning (Cont d) 5) Meet established energy budgets 6) Facilitates quality of construction and installation 7) Comprehensive training and documentation 8) Reduce risk of system failure/shutdown 12

13 When does Commissioning start? Commissioning starts at the planning phase and continues throughout all phases of the project. Commissioning supports total quality assurance in the design and development of facilities to meet client s needs. 13

14 Commissioning Activities in the PDS: Who is Involved Commissioning involves an integrated team comprising of: The Owner/Client The Project Manager The Commissioning Manager / Authority The Designer (Consultant) The Contractor Property Manager 14

15 Owner / Client Responsibilities Provides program requirements (technical & functional) Defines performance objectives & standards (technical data sheets) Sets Budgets & Schedules (milestones) Participates in selective Performance Tests Attends Training Participates to Interim acceptance process 15

16 Project Manager Responsibilities Overall responsibility for delivery of the project (of which Commissioning is part) Manages: - Contracts (consultants, contractors, client). - Relationship (Professional and Technical Services, Owner, Consultants, Commissioning Manager, Contractors, Property Manager. - All funding. 16
