Standard• Roles and responsibilities of key persons

for projects in regard to commissioning• Commissioning process and its

deliverables• Case studies

3

What is Commissioning?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.

4

What is Commissioning?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.

5

Commissioning Requirements forLEED 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

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

7

Why do we Commission?Why do we Commission?

• We Commission in order to provide a smooth transition from construction of the built works to an operational state.

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 systemWho should be responsible for each task. Other factors: Type of project- new construction, fit-up, general purpose office, laboratory, Heritage Facility

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)

12

Objectives ofCommissioning (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

13

When does Commissioning start?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.

14
