Course Description
This 1-hour HVAC Commissioning
Seminar Presentation will cover the
commissioning process as described in
the ACG Commissioning Guideline, as
well as valuable practical insight on skills,
strategies, and communication and
documentation protocols essential to
applying the process on “real-world” HVAC
controls projects.

Learning Objectives
At the end of this program, participants will be able to:
Explain the purpose, methodology, and benefits of the
commissioning process as it relates to HVAC controls.
Identify and distinguish between the five phases of
commissioning – (1) Pre-Design, (2) Design, (3) Construction, (4)
Acceptance, and (5) Post-Acceptance – and the activities carried out
in each of them.
Describe the documentation and deliverables that are essential to
the delivery of quality HVAC controls commissioning services.
Identify the roles and responsibilities of all commissioning team
members within the HVAC controls commissioning process, with
particular emphasis on the role of the commissioning provider.

Commissioning Process
A process of documentation, adjustment, testing,
verification, and training, performed specifically to
ensure that the finished facility operates in
accordance with the owner’s documented project
requirements and the construction documents.
It begins in pre-design and continues through
design, construction, and the life of the facility.
(BCA draft document, 2004.)

Commissioning
“retro” ;
“re”; or
