Commissioning of Lighting Systems Michael Chow, P.E., CxA, LEED AP BD+C Owner/Founder of Metro CD Engineering, LLC Course Objectives 1. 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 ACG COMMISSIONING GUIDELINE Commissioning Resources ASHRAE Guideline 0-2005 The Commissioning Process Commissioning Resources USGBC: LEED Reference Guides 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.” - IES Lighting Handbook, 9th Edition IES DG-29-11 1.
