Learning Objectives
To understand the 2015 Michigan
Energy Code’s basic requirements for
lighting system commissioning:
◦ Which lighting system elements must
be function tested and how
◦ How function testing results should be
documented
◦ How function testing (commissioning)
benefits construction projects

➢ Document the owner’s
project requirements (OPR)
➢ Provide documentation and
tools to improve the quality
of deliverables
➢ Verify and document that
systems and assemblies
perform according the OPR
➢ Verify that adequate and
accurate documentation for
systems and assemblies is
provided to the owner
➢ Verify that O&M personnel
and occupants are properly
trained
Objectives of Commissioning
➢ Provide a uniform and
effective process for the
delivery of construction
projects
➢ Deliver construction projects
that meet the OPR at the
time of delivery
➢ Utilize quality-based
sampling to detect systemic
problems
➢ Verify proper coordination
between systems and
assemblies as well as
between parties to the
delivery team

budget for Cx• Develop initial Cx
plan• Obtain acceptance
of PreDesign Phase Cx activities
• Verify BOD meets OPR• Update Cx plan • Develop Cx requirements
for inclusion in construction documents
• Develop draft Cx checklists
• Update scope and format of Systems Manual
• Define training requirements
• Perform Cx-focused design review
• Obtain acceptance of Design Phase Cx activities
• Update OPR• Update the Cx plan• Verify that submittals meet
the OPR• Develop detailed test
procedures and data forms• Verify that systems &
assemblies meet OPR• Deliver Systems Manual• Verify training of O&M
personnel and occupants• Obtain acceptance of
Construction phase Cx activities
• Verify seasonal testing of systems and assemblies
• Verify continual O&M personnel training
• Verify systems and assemblies meet CFR
• Verify continual updating of the Systems Manual

1. Lighting controls apply to all new construction spaces
and areas; and to alterations in which 50% or more of
the connected lighting load is impacted
2. Functional testing for controls must be performed and
satisfactorily passed with certified test results in order to
obtain a certificate of occupancy
3. Neither the lighting system design team nor the project
construction team can perform the lighting system
functional testing
Remember…
