Title: COMMISSIONING
1COMMISSIONING ???
2Key Definitions
3Key Definitions
- Commissioning (Cx)A quality assurance centered
process of documentation, training, adjustment,
testing, and verification, performed specifically
to ensure that the finished facility operates in
accordance with the owners documented project
requirements and the construction documents. It
begins in predesign and continues through design,
construction, and the life of the facility.(BCA
draft document, 2004.)
4Key Definitions
- Owner
- Financially or Politically Committed
- Users
- Operations Maintenance staff
- Key concept is Taking Responsibility for Quality.
5Key Definitions
- Commissioning Authority (CA)An individual (or
firm), representing the facility owner, who leads
the Commissioning effort until project
completion. - Key concept is Leading.
6Key Definitions
- Commissioning TeamA body of subject matter
experts who assist the Commissioning Authority in
carrying out the Commissioning Process. - Key concept is Managing.
7Key Definitions
- Commissioning Provider (CP)When the facility
owner separates out the duties of the CA. - An independent third-party commissioning firm
- An A/E firm
- The general contractor, or
- Owner's in-house personnelSelected by the CA, to
assist the Commissioning Team in handling the
technical requirements of the Commissioning
process - Key concept is Doing.
8Key Definitions
- Owners Project Requirementsa.k.a. Design Intent
Document - Detailed, largely non-technical document
developed under the leadership of, and primarily
by, the Commissioning Authority from discussions
with the facility owner. - States concepts, budget, and performance criteria
to which the completed project must conform. - The basis for Building Commissioning.
9Key Definitions
- Basis of DesignA document that records the
concepts, calculations, decisions, and product
selections to meet the Owners Project
Requirements and to satisfy applicable regulatory
requirements, standards, and guidelines. - Includes both narrative descriptions and lists of
individual items that support the design process.
(ASHRAE Draft Guideline 0-200X, The Commissioning
Process, dated August 2002.) - Technical expression of the less technical
Owner's Project Requirements.
10Key Definitions
- Commissioning Plan (CxP)A document prepared by
the Commissioning Authority that outlines the
following - Organization of the Cx Team
- Member responsibilities
- Schedule of Cx events
- Allocation of Cx resources, and
- Documentation requirements of the Cx process.
11Key Definitions
- Commissioning (Cx)A planned and integrated
systematic process to ensure, through documented
verification, that all Building Systems perform
interactively according to the Owner's Project
Requirements. - Commissioning procedures require a collaborative
team effort and begin in the predesign phase,
continue through the design and construction
phases into the initial occupancy phase,
including the training of OM staff.
12Key Definitions
- Recommissioning (ReCx)A periodic event in the
life of an existing building that reapplies the
original commissioning plan in order to return or
keep the facility operating according to the
original design intent / owners project
requirements while accounting for current
operating and code requirements.
13Key Definitions
- Retrocommissioning (RetroCx)a.k.a. Existing
Building Commissioning - RetroCx is for an existing building that has
never been commissioned. - Employs a total facility component and systems
deficiency analysis to create a Commissioning
Plan. - May or may not emphasize returning the facility
to its original design intent.
14Key Definitions
- Continuous Commissioning (CCx)a.k.a. Ongoing
Commissioning - Upon completion of Commissioning,
Recommissioning, or Retrocommissioning, Owner
continues to collect and compare baseline data on
selected building systems against
post-commissioning results to ensure that the
monitored systems function optimally throughout
their design lives. - Made possible because of the initial
commissioning process.
15Why Commission?
16Why Commision?
- Better BuildingsBuilding owners are finding
that the energy, water, and productivity savings
achieved by commissioned buildings can offset the
cost of the commissioning process. Studies
indicate 8 to 20 percent savings in building
operating costs over those in a non-commissioned
building. - Source Building Commissioning Guide, Version
2.2, GSA/DOE, dated July 30, 1998
17Why Commision?
- Better PeopleAside from achieving documented
costs savings and cost avoidance, commissioning
enhances customer satisfaction and assures proper
ongoing training of the facility Operations
Maintenance personnel.
18- Better Stewardship
- Sustainablity
- Reduce resource depletion of energy, water and
raw materials - Create built environments that are livable,
healthy and productive - LEED Certification

Why Commision?
19Why Commision?
For LEED 2.1 CertificationPrerequisite
- Engage a Cx team that does not include
individuals directly responsible for project
design or construction management. - Review the Design Intent and the Basis of Design
docs. - Incorporate Cx requirements into the construction
documents. - Develop and utilize a Cx plan.
- Verify installation, functional performance,
training, and operation and maintenance
documentation. - Complete a Cx report.

- Leadership in Energy and Environmental
Design--U.S. Green Building Council
20Why Commision?
For LEED 2.1 Certification Additional Credit
- Cx authority independent of the design team to
review design prior to the construction documents
phase. - Independent Cx authority to review construction
documents near completion of the construction
document development and prior to issuing the
contract documents for construction.. - Independent Cx authority to review contractor
submittals relative to systems being
commissioned. - Provide the owner with a single manual that
contains the information required for
re-commissioning building systems. - Have a contract in place to review building
operation with OM staff, including a plan for
resolution of outstanding Cx-related issues
within one year after construction completion. - Leadership in Energy and Environmental
Design-- U.S. Green Building Council

24What Does Commissioning Cost?
25What Does Commissioning Cost?
- Commissioning(Cx)
- (New Construction)
- 0.5 to 1.5 Percent of Total Construction Cost
- Retrocommissioning(RetroCx)
- (Existing Construction)
- 3.0 to 5.0 Percent of Total Operating Cost

26What Does Commissioning Cost?
- The Economics of Commissioning
If planned correctly and implemented early enough
in the design process, commissioning can be
included with little or no cost impact.
Without Commissioning
First Year Warranty Period Costs
Design Phase Costs
Construction Phase Costs
Based on research findings from University of
Wisconsin, ASERTTI Training Module, 1998
27What Does Commissioning Cost?
- The Economics of Commissioning
- An Initial Budget Setting Rule-of-Thumb
- 2 - 3 of mechanical construction cost
- plus
- 1 - 2 of electrical construction cost
- (Source BCA. Based on six science building
projects)
28- Commissioning
- Results in a comfortable, healthy working
environment that promotes productivity. - Achieves both capital cost avoidance and annual
operating cost reduction. - Increases facility maintainability and
reliability via training of Facility Management
Personnel. - Improves the overall quality of the completed
initiative.
