Building Commissioning is proven systematic “process” that
provides documented confirmation, measurement, and
verification that the building systems are of design, quality,
construction and function in compliance with the Owner
identified operational and sustainability needs (OPR).
The “Process” is performed under a formal detailed Cx Plan.
The Plan is a LIVE document maintained throughout the
“Process” and the final deliverable product is a completed
binder(s) or eDoc containing all the Commissioning
Documents. Communication and organization of the Team
and Process are a major contributing factor toward
successful Commissioning.
This seminar provides an „overview‟ of Building Commissioning including Why, When, the Benefits, Costs,
LEED “Commissioning Related” Credits, LEED Commissioning specific Credits (Fundamental and
Enhanced Commissioning), and Measurement & Verification. This is the process for „Sustainability
Verification‟ of Systems & their Performance.
What is Commissioning ?
ASHRAE Guideline 0: “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 Owner's Project Requirements.”
BCxA: “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
Owner's Project Requirements.”
A planned and integrated systematic
process to ensure, through
documented verification, that all

When to Implement Commissioning ?
Commissioning is most successful when
implemented in the Planning Phase. Include the
CxA (Owner’s Facility Maintenance and Design
Engineers) in development of the Owner’s Project
Requirements (OPR). This facilitates a complete
and proper OPR.
The CxA should also review the Design Engineer’s
Scope of Work for appropriate inclusion of
commissioning process related scope for the
Design, Construction, and Warranty Phases.
It is never too late to implement commissioning, but the
continuity and conformity amongst the Team is subject to
clear scope and responsibilities for the entire Team.
Value of Commissioning
•Reduce energy and water waste.
•Reduce CO2 and improve IAQ.
•Adds Value to the building by optimizing comfort, performance, and
operation.
•Promotes Healthy working environment that promotes productivity.
•Reduces operating costs.
•Improves employee/occupant comfort.
•Reduces operation and comfort complaints of occupants.
•Increased Rents
•Tenant Retention
•Increase market value of the building.
•Improves Operating Life of equipment.
•Capital Cost Avoidance
•Facility Maintainability.
•Reliability of the Facility.
•Reliability of the Facility O&M Personnel Training and
Documentation.
•Overall Quality of the Completed Initiative.
Verifies the required, specified, submitted, contracted, and stated
Benefits of Commissioning
In the 70’s and 80’s you had years to design and construct a project.
The objective was to not have any Addendums or Change Orders.
Due to the fast-tracking of design and construction, the high
complexity of building systems, inter-operabilities, controls and
energy management, Addendums have been commonplace
(unfortunately). Each Subcontractor is responsible and test his own
part of the work. Who’s verifying they have, and verifying the
systems as a whole and the integration of the systems. Well, that
would be the Commissioning Agent.
The Commissioning Process intends to provide a Catch-All for “issues”
during the Design, Submittal, and Construction Phases, before the
they are constructed or become BIG ISSUES.
Benefits of Commissioning
Imaging the indirect savings due to reduction in Warranty Call-Backs,
Complaint time, Occupant Time, etc.
The energy savings we can identify with all the systems working
properly, operating schedule operating properly, and similar.
Lawrence Berkley Laboratories performed a study of 20,000 (approx)
buildings built since 1975 comparing buildings that Were
Commissioning against those that Were Not.
This study identified the Non-Energy Benefit cost savings due to lost
time for calls and call backs came to an average of about 17
cents/SqFt/Year.
It also identified that a building that is NOT Commissioned will cost
about 8-20% more in energy cost to operate.
Benefits of Commissioning
•Design Reviews: Savings are realized by reducing Change Orders
by review for compliance with OPR, BOD, completeness of Scope,
constructability, serviceability and communication of trade
documents.
•Bid Reviews (NOT LEED Req’d): Appropriate “Inclusion” of
Commissioning Process.
•Submittal Reviews: Another set of eyes for review of compliance
with OPR, BOD, and systems inter-relationships.
•Construction Installation Observation: Another set of eyes
while the systems are accessible for observation.
•Performance Verification: Functional Performance and
Operations, fine-tuning, debugging, conflicts, faulty
devices/equipment, Control Programming and Interfacing.
Verification for operation, energy, comfort, and operational costs.
Benefits of Commissioning
•TAB Verification (NOT LEED Req’d): (Test, Adjust, and Balance)
Field Verification (spot checks, % samplings, full-verification) verifies
operation settings for systems, and those receiving work, repairs,
adjustment, or modification subsequent to Functional Testing.
•Warranty Review: The identified “Issues”, newly realized “issues”
of occupied operations, and modifications can be addressed, resolved,
and fixes implemented prior to expiration of Warranties.
•O&M Manual (Systems Manual) Review: for completeness of
content.
•Systems Operations & Maintenance Manual (SOMM) (NOT
LEED Req’d): Detailed O&M that typically includes parts systems,
parts lists, spares lists, complete performance, service, and
maintenance instruction for the systems “As Installed and Configured”
(not per piece of equipment/device), every operating sequence,
mode, failure, recovery, and restart method and expected result,
service and warranty contact info, and more…
Selecting a Commissioning Agent
Selecting a CxA it is important to select a CxA with Technical
expertise in “Commissioning” who also has technical experience in
design.
The CxA develops Design and Installation CheckLists, and the
Functional Performance Test Procedures utilized to verify compliance
with the OPR, BOD, and Construction Documents. The thorough and
detailed continuous review, data collection, and coordination effort
led by the CxA provides insight of the all-inclusive performance and
operation of the systems provided by no single other Team member
or Trade.
The CxA’s scope and effort is concentrated on the performance,
quality, and maintainability of the systems from start-to-finish.
An “Independent Third-Party Commissioning Agent” under direct
contract to the Owner is the preferred contractual arrangement.
This brings objectivity and practical experience to the project to
provide a consistent level of assurance that the Owner’s best
interests will be served.
Selecting a Commissioning Agent
Although Contractors may have the knowledge and capability to test the
equipment they install, they may not be skilled at testing or diagnosing
integration problems. It is difficult for Contractors to objectively test and assess
their own work, especially since repairing deficiencies found through
commissioning may increase their costs.
Although Design Engineer‟s may have the knowledge to perform as the
Commissioning Agent, they may have difficulty in performing proper testing, as
most are not exclusively dedicated to Commissioning.
The CxA needn't be a design engineer, GC, MEP, Controls, or TAB contractor.
The CxA should be experienced in design, inspection, testing, and experience in
leading and performing the Commissioning process and it‟s responsibilities
(learned experience).
LEED Fundamental Commissioning permits the CxA to be a member of the Design
Firm, Contractor Firm, or Owner.
LEED Enhanced Commissioning requires an “Independent Third-Party
Commissioning Agent” not employed by, or subsidiary to, the Design Team
Firm(s) or Contractor(s).
Selecting a Commissioning Agent
The Commissioning Agents verifies whether or not the Contractor‟s
documentation and systems met the Specification requirements.
The Commissioning Agent identifies any perceived deficiency, or
necessary Design improvement or change.
The Commissioning Agent produces verification tests and reports that
directs the actions of Contractors for testing purposes only by
reference to the Design Engineer‟s design documents.
The verification tests are repeated from the content of the Design
Documents and Approved Submittals, developed in the format of a
Test Procedure to demonstrate the required performance and produce
the expected result.
Commissioning reports may recommend corrective actions to be
implemented by the Contractor or the Design.
Benefits of Commissioning
While developing the Checks and Test is when most problems, issues,
and discrepancies are found.
Secondly is when they are tested, and we find many holes that were
incomplete, not verified, not connected, not programmed, etc. by the
Contractors as there are many hands bringing the building together.
These are to be expected to an extent, but often the CxA is brought in
to Test Phases to obtain partial occupancy while contractors are still
piecing the puzzle and yet to thoroughly complete their own testing
(which should be specified clearly). This is typical due to delivery
schedules, lease schedules, and substantial completions.
The Value that the CxA brings to the table is tremendous!
The CxA is facilitating the team and managing the Cx Process to help
the construction process to go as smoothly as possible.
Behind the Scenes
50% of the Cx Agent’s effort is performed behind the scenes
reviewing, verifying, documenting, collecting data and detail, building
and re-verifying the CheckLists and Test Procedures with every
change order and submittal, updating and maintaining the Cx Plan,
building the Final Cx Report and Systems Manuals, and coordinating
with the Team.
The consolidated product delivered by the CxA at the project
completion reveals only the final data.
Commissioning Agents utilizing Cloud or Web based systems, or
documents accessible via the Web are the current trend to keep
document management, data, status, and issues accessible to the
Team.
Cooperation with the SubContractors (MEP, Controls, TAB) and
Vendors and a thorough and complete Scope of Work for Contractors
inclusive of Commissioning efforts and responsibilities is of utmost
importance.
When to Implement Commissioning ?
Commissioning is most successful when
implemented in the Planning Phase. Include the
CxA (Owner’s Facility Maintenance and Design
Engineers) in development of the Owner’s Project
Requirements (OPR). This facilitates a complete
and proper OPR.
The CxA should also review the Design Engineer’s
Scope of Work for appropriate inclusion of
commissioning process related scope for the
Design, Construction, and Warranty Phases.
When to Implement Commissioning ?
It is important to involve the Commissioning
Authority as early in the project as possible. This
allows the Authority opportunity to review the
design intent (OPR) and BOD for the project, and
verify implementation. Additionally to begin
scheduling Commissioning activities, and begin
writing specifications into Bid Documents for
Contractors.
It is never too late to implement commissioning, but the continuity
and conformity amongst the Team is subject to clear scope and
responsibilities.

  • 6. Building Commissioning is proven systematic “process” that provides documented confirmation, measurement, and verification that the building systems are of design, quality, construction and function in compliance with the Owner identified operational and sustainability needs (OPR). The “Process” is performed under a formal detailed Cx Plan. The Plan is a LIVE document maintained throughout the “Process” and the final deliverable product is a completed binder(s) or eDoc containing all the Commissioning Documents. Communication and organization of the Team and Process are a major contributing factor toward successful Commissioning. This seminar provides an „overview‟ of Building Commissioning including Why, When, the Benefits, Costs, LEED “Commissioning Related” Credits, LEED Commissioning specific Credits (Fundamental and Enhanced Commissioning), and Measurement & Verification.

  • 11. When to Implement Commissioning ? Commissioning is most successful when implemented in the Planning Phase. Include the CxA (Owner’s Facility Maintenance and Design Engineers) in development of the Owner’s Project Requirements (OPR). This facilitates a complete and proper OPR. The CxA should also review the Design Engineer’s Scope of Work for appropriate inclusion of commissioning process related scope for the Design, Construction, and Warranty Phases. It is never too late to implement commissioning, but the continuity and conformity amongst the Team is subject to clear scope and responsibilities for the entire Team.
  • 12. Value of Commissioning •Reduce energy and water waste. •Reduce CO2 and improve IAQ. •Adds Value to the building by optimizing comfort, performance, and operation. •Promotes Healthy working environment that promotes productivity. •Reduces operating costs. •Improves employee/occupant comfort. •Reduces operation and comfort complaints of occupants. •Increased Rents •Tenant Retention •Increase market value of the building. •Improves Operating Life of equipment. •Capital Cost Avoidance •Facility Maintainability. •Reliability of the Facility. •Reliability of the Facility O&M Personnel Training and Documentation. •Overall Quality of the Completed Initiative. Verifies the required, specified, submitted, contracted, and stated
  • 13. Benefits of Commissioning In the 70’s and 80’s you had years to design and construct a project. The objective was to not have any Addendums or Change Orders. Due to the fast-tracking of design and construction, the high complexity of building systems, inter-operabilities, controls and energy management, Addendums have been commonplace (unfortunately). Each Subcontractor is responsible and test his own part of the work. Who’s verifying they have, and verifying the systems as a whole and the integration of the systems. Well, that would be the Commissioning Agent. The Commissioning Process intends to provide a Catch-All for “issues” during the Design, Submittal, and Construction Phases, before the they are constructed or become BIG ISSUES.
  • 14. Benefits of Commissioning Imaging the indirect savings due to reduction in Warranty Call-Backs, Complaint time, Occupant Time, etc. The energy savings we can identify with all the systems working properly, operating schedule operating properly, and similar. Lawrence Berkley Laboratories performed a study of 20,000 (approx) buildings built since 1975 comparing buildings that Were Commissioning against those that Were Not. This study identified the Non-Energy Benefit cost savings due to lost time for calls and call backs came to an average of about 17 cents/SqFt/Year. It also identified that a building that is NOT Commissioned will cost about 8-20% more in energy cost to operate.
  • 15. Benefits of Commissioning •Design Reviews: Savings are realized by reducing Change Orders by review for compliance with OPR, BOD, completeness of Scope, constructability, serviceability and communication of trade documents. •Bid Reviews (NOT LEED Req’d): Appropriate “Inclusion” of Commissioning Process. •Submittal Reviews: Another set of eyes for review of compliance with OPR, BOD, and systems inter-relationships. •Construction Installation Observation: Another set of eyes while the systems are accessible for observation. •Performance Verification: Functional Performance and Operations, fine-tuning, debugging, conflicts, faulty devices/equipment, Control Programming and Interfacing. Verification for operation, energy, comfort, and operational costs.
  • 16. Benefits of Commissioning •TAB Verification (NOT LEED Req’d): (Test, Adjust, and Balance) Field Verification (spot checks, % samplings, full-verification) verifies operation settings for systems, and those receiving work, repairs, adjustment, or modification subsequent to Functional Testing. •Warranty Review: The identified “Issues”, newly realized “issues” of occupied operations, and modifications can be addressed, resolved, and fixes implemented prior to expiration of Warranties. •O&M Manual (Systems Manual) Review: for completeness of content. •Systems Operations & Maintenance Manual (SOMM) (NOT LEED Req’d): Detailed O&M that typically includes parts systems, parts lists, spares lists, complete performance, service, and maintenance instruction for the systems “As Installed and Configured” (not per piece of equipment/device), every operating sequence, mode, failure, recovery, and restart method and expected result, service and warranty contact info, and more…
  • 17. Selecting a Commissioning Agent Selecting a CxA it is important to select a CxA with Technical expertise in “Commissioning” who also has technical experience in design. The CxA develops Design and Installation CheckLists, and the Functional Performance Test Procedures utilized to verify compliance with the OPR, BOD, and Construction Documents. The thorough and detailed continuous review, data collection, and coordination effort led by the CxA provides insight of the all-inclusive performance and operation of the systems provided by no single other Team member or Trade. The CxA’s scope and effort is concentrated on the performance, quality, and maintainability of the systems from start-to-finish. An “Independent Third-Party Commissioning Agent” under direct contract to the Owner is the preferred contractual arrangement. This brings objectivity and practical experience to the project to provide a consistent level of assurance that the Owner’s best interests will be served.
  • 18. Selecting a Commissioning Agent Although Contractors may have the knowledge and capability to test the equipment they install, they may not be skilled at testing or diagnosing integration problems. It is difficult for Contractors to objectively test and assess their own work, especially since repairing deficiencies found through commissioning may increase their costs. Although Design Engineer‟s may have the knowledge to perform as the Commissioning Agent, they may have difficulty in performing proper testing, as most are not exclusively dedicated to Commissioning. The CxA needn't be a design engineer, GC, MEP, Controls, or TAB contractor. The CxA should be experienced in design, inspection, testing, and experience in leading and performing the Commissioning process and it‟s responsibilities (learned experience). LEED Fundamental Commissioning permits the CxA to be a member of the Design Firm, Contractor Firm, or Owner. LEED Enhanced Commissioning requires an “Independent Third-Party Commissioning Agent” not employed by, or subsidiary to, the Design Team Firm(s) or Contractor(s).
  • 19. Selecting a Commissioning Agent The Commissioning Agents verifies whether or not the Contractor‟s documentation and systems met the Specification requirements. The Commissioning Agent identifies any perceived deficiency, or necessary Design improvement or change. The Commissioning Agent produces verification tests and reports that directs the actions of Contractors for testing purposes only by reference to the Design Engineer‟s design documents. The verification tests are repeated from the content of the Design Documents and Approved Submittals, developed in the format of a Test Procedure to demonstrate the required performance and produce the expected result. Commissioning reports may recommend corrective actions to be implemented by the Contractor or the Design.
  • 20. Benefits of Commissioning While developing the Checks and Test is when most problems, issues, and discrepancies are found. Secondly is when they are tested, and we find many holes that were incomplete, not verified, not connected, not programmed, etc. by the Contractors as there are many hands bringing the building together. These are to be expected to an extent, but often the CxA is brought in to Test Phases to obtain partial occupancy while contractors are still piecing the puzzle and yet to thoroughly complete their own testing (which should be specified clearly). This is typical due to delivery schedules, lease schedules, and substantial completions. The Value that the CxA brings to the table is tremendous! The CxA is facilitating the team and managing the Cx Process to help the construction process to go as smoothly as possible.
  • 21. Behind the Scenes 50% of the Cx Agent’s effort is performed behind the scenes reviewing, verifying, documenting, collecting data and detail, building and re-verifying the CheckLists and Test Procedures with every change order and submittal, updating and maintaining the Cx Plan, building the Final Cx Report and Systems Manuals, and coordinating with the Team. The consolidated product delivered by the CxA at the project completion reveals only the final data. Commissioning Agents utilizing Cloud or Web based systems, or documents accessible via the Web are the current trend to keep document management, data, status, and issues accessible to the Team. Cooperation with the SubContractors (MEP, Controls, TAB) and Vendors and a thorough and complete Scope of Work for Contractors inclusive of Commissioning efforts and responsibilities is of utmost importance.
  • 22. When to Implement Commissioning ? Commissioning is most successful when implemented in the Planning Phase. Include the CxA (Owner’s Facility Maintenance and Design Engineers) in development of the Owner’s Project Requirements (OPR). This facilitates a complete and proper OPR. The CxA should also review the Design Engineer’s Scope of Work for appropriate inclusion of commissioning process related scope for the Design, Construction, and Warranty Phases.
  • 23. When to Implement Commissioning ? It is important to involve the Commissioning Authority as early in the project as possible. This allows the Authority opportunity to review the design intent (OPR) and BOD for the project, and verify implementation. Additionally to begin scheduling Commissioning activities, and begin writing specifications into Bid Documents for Contractors. It is never too late to implement commissioning, but the continuity and conformity amongst the Team is subject to clear scope and responsibilities.
  • 24. LEED v3 2009 EAp1 Fundamental Commissioning  Develop and Maintain a Commissioning Plan  Functional Performance Testing of Equipment & Systems  Commissioning Documentation EAc3 Enhanced Commissioning CxA is required to be an Independent-Third Party  Peer Review of Design and Submittals  Systems Operation Manual  8-10 Month Warranty/Occupancy Commissioning Review
  • 25. FUNDAMENTAL Cx Sustainability Verification Engage a Commissioning Team that does NOT include individuals Directly responsible for Project Design or Construction Management. (individuals employed by those firms is permitted).

Existing Building Cx Re-Commissioning & Retro-Commissioning: 5 % to 10 % Excess Operating Expense Savings from Re-Commissioning or Retro-Commissioning $15k/year in Incremental Operating Expenses 5% Excess duct leakage for an average facility with 12 AHUs and 200k cfm. $100,000 in Capital Savings, and $6,000/year Energy Savings for a 10% performance reduction on a 250-Ton AHU system, at approximate $4,000/Ton installation cost, due to extended run times. Utilities = 20% of total building operating cost. A 10% reduction on a 100,000sf building = approximately $20,000/yr
  • 41. Measurement & Verification (M&V) Is the field measurement and verification of installed operating facility and system performance in comparison to the Design Engineer‟s identified energy model and basis of design benchmarks. (energy, water, CO2, IAQ, comfort, etc.)
  • 42. $ Project Cost of Commissioning $ An Initial Budget Setting “Rule-of-Thumb” is • 2 to 3 % of Mechanical Construction Cost PLUS • 1 to 2 % of Electrical Construction Cost Varies based on: • Scale of the Project • Commissioning Scope (variables and extras) • Complexity of Systems • Quantity of Equipment and Systems to be Commissioned. This rule includes Design, Construction, Commissioning and Owner Team participation and costs.
