FAQs about EAp1 :

Can the CxA authority be a member of the design or construction team?

What type of certification is the commissioning agent required to have?

The comissioning process turned up a few issues with the commissioned systems that should be corrected. Do we have to correct these issues and include documentation of that as part of our LEED documentation?

Our project, registered under LEED 2009 Italia NC, consists in a building whose occupancy will take place in October 2014. It was not possible to conduct the Functional Performance Testing during summer, and the project team wants to submit the whole documentation on LEED Online before the period of the functional test in winter. There will be an intermediate Functional Performance Test in October, at the beginning of the heating season. After the submission of the documentation to GBCI, the CxA will manage to complete Functional Performance Testing during the peak heating period in December 2014 / January 2015 and during the peak cooling period in July 2015. Can the submission be considered feasible at the end of October 2014, taking into account that the following measures have already been taken by the CxA? - a Letter of Intent for the Owner which states the verifiability of the Functional Performance Tests in Dec 14 and Jul 15; - the OPR, the BOD and the construction Checklist were performed and verified.

As you know, I cannot speak for GBCI and the reviewer team, but from what I gather, you are hoping to submit your final documentation with no functional testing done at all. In my opinion, that will not be acceptable. You can certainly ask for a conference call with the reviewer team, and see what they think. In the many projects that I have been involved with, at most we might have a dozen or so outstanding functional tests left to complete at the time of submittal, either due to some action items not resolved (that requires retesting), or truly seasonal in nature. Many, many sequences and functional tests can be done regardless of the temperature through various means, leaving a selection of items that truly need the right temperatures outside to provide the level of confidence that is appropriate as the standard of care for commissioning.
