What is LEED™?
– Consensus Based Green Rating
System for building design,
construction and operation
What is LEED™?
– It analyzes and measures multiple
aspects of a building’s design and
construction
Why LEED Certification?
– There is no definition for “LEED
certifiable”
– Third-party verification assures you
that what was designed and planned
is in fact what you received.
What is Commissioning?
Term derived by the Navy–
 A commissioned ship is one deemed
ready for service.
 Material, systems and staff have
successfully completed a thorough
quality assurance process
What is Commissioning?
The Commissioning Process is a qualityoriented process for achieving, verifying,
and documenting that the performance of
facilities, systems, and assemblies meets
defined objectives and criteria.”
-- ASHRAE Guideline 0-2005
What is Commissioning?
It’s not just for testing
at the end!
What is Commissioning?
–During Design
»Document Review of Basis of Design
(BOD)
»Helps Owner create the Owner’s
Program Requirements (OPR)
»Defines scope of commissioning
»Performs Cx Review
»Creates Cx Plan
»Incorporates Cx reqm’t in the CDs
What is Commissioning?
–During Construction
»Update the Cx Plan and Schedule
»Review control sequences
»Update test procedures
»Document construction observations
»If performing Enhanced Cx:
»reviews submittals against Cx Plan,
BOD and OPR
»develops systems/ O&M Manuals
What is Commissioning?
–During Cx
»Functional Performance Testing (FPT)
»Documentation of deficiencies found
»Retesting of deficiencies
»If En Cx performed then training of
O&M Personnel
»Final Report
What is Commissioning?
–Enhanced Cx Warranty
»Returns within 10-12 months to
confirm systems are still working
»Confirms adjustments for occupancy
changes are made

Gaps between disciplines
result in:
• Poor coordination
• Lost details
• Costly change orders
• Delays in schedule

Why Commission?
New Project Team Configuration with
Commissioning
Cx helps fill
the gaps in
coordination
Cx encompasses
“All”
Why Commission?
Cx helps by:
• Setting clear, measurable goals for
everyone
– Verifies owner’s requirements are being
met throughout the design and
construction phases
• Establishing accountability
– Changes the way people perform
– Allows designers and contractors to
measure success as well as deficiency
Why Commission?
• Increases the Quality of the Process
– Prevents/resolves problems
– Designers focus on owner’s needs
• Discover/correct design issues early
in design
• Improves specifications & design
documents
• Reduces RFI’s & change orders
• Prioritize systems identified for early
completion
Why Commission?
• Contractors focus on quality work
– Improves submittal process
– Provides resource for MEP
coordination prior to construction
– Catch problems at the start of
installation
– Test finished work to verify proper
operability
– Creates team atmosphere and
accountability
Why Commission?
• Improves
– Energy performance
– Comfort
– Air quality
– Occupant productivity
– Equipment life
– Maintainability
– Facility staff preparedness

and energy efficiency measures

Location of projects in the database
SAMPLE
• 643 buildings
- 562 existing
- 82 new
• 99 million

• $43 million
investment
• 26 states

Deficiencies discovered …
Payback times: new construction
Excellent outcomes for all bldg types
Why Commission?
• Risk Management
- Ensures that a building owners get what
they pay for
- Provides insurance for policymakers and
program managers that their initiatives
actually meet targets
- Detects and corrects problems that would
eventually surface as far more costly
maintenance or safety issues.
In Summary
LEED Certification assures Glendale
Community College that project’s meet
the green goals you established
Commissioning verifies that installed
systems work properly and meet the
defined criteria
Thank You.
