Commissioning of Lighting SystemsMichael Chow, P.E., CxA, LEED AP BD+COwner/Founder of Metro CD Engineering, LLC

Course Objectives1. The participant will be able to evaluate how to effectively use both the IES

DG-29-11, The Commissioning Process Applied to Lighting and Control Systems, and the ASHRAE Guideline 0-2005 The Commissioning Process as tools to develop an effective lighting commissioning plan

2. The participant will be able to determine the technical requirements for commissioning lighting and control systems to achieve owner performance criteria.

3. The participant will explore the requirements for verification and acceptance activities during each phase of the Commissioning Process.

Commissioning Resources IES DG-29-11, The Commissioning Process Applied to Lighting and Control Systems

Commissioning Defined “A quality-focused process for enhancing the delivery of a project. The

process focuses upon verifying and documenting that the facility and

all of its systems and assemblies are planned, designed, installed,

tested, operated, and maintained to meet the owner’s project

requirements (OPR).”

- ASHRAE Guideline 0-2005 The Commissioning Process

Commissioning of Lighting Systems Defined

“A systematic process that ensures that all elements of

the lighting control system perform interactively and

continuously according to documented design intent

and the needs of the building owner.”
