Intent:
- Verify that building’s energy related systems are installed, calibrated, and perform accord to BOD (Basis of Design), OPR (Owner’s Project Requirements), and Construction Documents.
Implementation: (UPDATED!)
- Designate a Commissioning Authority (CxA) to lead, review, and oversee completion of commissioning process
- Must be experienced for two similar projects
- independent person
- for projects less that 50,000 SF, commissioning can be done by design or construction team.
- 6 Requirements of CxA
- REVIEW the BOD & OPR
- Develop a Commissioning PLAN
- VERIFY the Installation & Performance of the Systems
- REPORT the results and finds to the owner
- A SUMMARY is to be completed with the report
- CONSTRUCTINO DOCUMENTS are to incorporate any commissioning requirements
- Commissioned Systems Include:
- HVAC
- Lighting
- Renewable Energy
- Domestic Hot Water
Code:
- none
Submittal Phase:
- construction
Extra Credit:
- none
More Energy & Atmosphere Credits
- EA P1 – Fundamental Commissioning of the Building Energy Systems (prerequisite)
- EA P2 – Minimum Energy Performance (prerequisite)
- EA P3 – Fundamental Refrigerant Management (prerequisite)

Hi Pat,
you have a typo here EAp1(construction). Thanks for your web site.
jean
In ‘Madatory Report’, No. 3 should say ‘Contract Documents’ (page 158). ‘As Built Drawings’ are something entirely different…
Where did you find ‘Mandatory Report’ and ‘Fundamental Report’? I do not see it in the book any where…
Peter,
there is a handy chart delineating the tasks of the commission team for the prereq and for credit 3,in the ref guide,Credit three section. learn those and which tasks that the commissioning agent alone is responsible for. I listed it in a comment in credit 3 this website.
I think I came across those terms you mentioned in the Colorado study materials..
EA PR # 1 – I’m confused on the CXA requirements. Is the CXA responsible for # 3 thru 6 under requirements? It states commissioning team. Is the CXA the entire commissioning team?
Thanks for the help.
I will be having a lot of questions here in the next few weeks.
Pat thanks for a great site.
Where can I find the list for Mandatory Report in the Reference Guide 2.2 book, as shown on your study guide? Thank you.
Hey,
I am also not finding the “mandatory report” anywhere in P1. Is it applicable in EAc3? Someone please help.
Hi Guys,
I apologize for the “older” informatinon on this post. It has since been updated to the latest edition.
Again, Sorry for the confusion.
Can I use my HVAC designer to commission my 10,000 SF building? What is required to prove that my comissioner is qualified for LEED?
Riddle me this?
If, as stated in the book, the agent must have experience on two prior projects,
Tell me how someone new can ever become a commissioning agent?
Anyone can have commissioning done on their building, LEED or not. Basically LEED wants their commisioning done by people who have done at least two non-LEED projects before they are allowed to commission a building trying to achieve LEED certification
Perhaps this is what some were getting to above. If so, forgive me as I am being dense(er) this weekend. Please clarify 2 issues re: EA p1:
1) If you look at the Requirements for EA p1 (page 153, third ed), it states that the requirement of the commissioning team is to disignate an individual as the CxA. However, in Table 1 (page 155), this responsibility goes to either the Owner or Project Team. Comm. Team or Proj. Team?
2) If you look at Table 1, there are only TWO requirements specific for the CxA alone. 1) To verify install./perform. and 2) Complete a summary commissioning report. Is this true?
Full review of the requirements for the commissioning process, is is quite clear as to WHAT must be done. However, not so clear as to WHO must be responsible for doing the WHAT.
Could be important to the test, given the fact we’ve all been forewarned to be on the lookout for bits of trickery in the phrasing of the exam questions. If the question has as options both the 2 tasks AND the 6 tasks, which is the correct answer. Table 1 is very clear about this, no?
Hey Pat,
What is the difference between fundamental and enhanced commissioning?
Thanks for all the good work you are doing on this site.
Hey Nick
Regarding your riddle asking how someone new can ever become a commissioning agent.
If they work on 2 (similar) projects under 50,000 s.f as part of design or const. team with required experience, they might qualify themselves!
It is my contention that the operative words in qualifying a CxA are “should” and “similar”. A CxA with experience in commissioning office buildings should not be precluded from commissioning an office building simply because it includes the addition of photovoltaic cells.
We must stretch the envelope on every project…
Here is my trick to remember this part:
“energy systems must be impeccable using commissioning”
in-pe-cca : INstalled-PErforming-CAlibrated ,following
b-l-e:
1. b-asis of design)
0. l-aw=owner, requirements
6. e-onstruction doc (notice how “e” looks like a “c” and “mirrored” 6 )
then we need to list the 6 requirements to accomplish it:
imagine the process:
1. review b and l
2. commissioning plan creation
3. verify in & pe
4. report to l
5. add summary
6. e-docs to add commissioning
hi Pat
on the sample test bldg. green.com question #20 states documentation of EA1 also contributes documentation to which credits?
EAp1 was one of the answers. When I was being taught this course, I was told that prerequisites do NOT count as a “credit” and that is one way of tricking people.
What do you think?
thanks
Lisa
Typo and discussed in another thread. You are right.
1 mnemonic to remember who is responsible for the the EA credits
odc /d/ o/d/d/ odc / d/ d/ o
See a pattern in the second half. Its a mirror image with odc at the centre.
WHere O-owner, D-design team, C – contractor
It helps me. Hope it helps you too
nice …Thanx Arpita
Arpita, Gr8 job:). This is awesome!!
Doeas the commissioning agent has to be LEED AP or CxA.?
Can a commissioning agent who works for the owener (university) be the comissioning agent?
Hi, I’m confused by this requirement, as stated in LEED CS 2.0. On page 171 (Requirements) it says the CxA “shall have documented commissioning authority experience”… but on 173, two pages down (Strategies) it says “For LEED-CS projects a qualified
CxA should have experience with two
other projects of similar managerial
and technical complexity”. Any insight appreciated. I’m a “green” Green Associate who’s just been asked to perform CxA…
Hi, I’m confused with the commissioning system and the measurement and verification system. They seem to be the same thing to me. Are they both run by the CxA? What is the difference?
Hi everyone,
Does Best Practice Commissioning, Enhanced Commissioning and Additional Commissioning mean all the same thing?
Can someone explain the difference between best practice and fundamental commissioning? Is there a flow chart or diagram I can find on the internet?
