The Guide for Commissioning Building Electrical Systems seeks to help you understand the commissioning process and provides recommendations for successful projects. The chapter sequence first discusses reasons to commissioning electrical systems and follows by overviewing project schedules/budgets and levels 1 through 5 of the commissioning process. Using a mentor-based approach, the chapters overview development of documentation, such as Commissioning Plans, Commissioning Specifications, Test Equipment Plans, checklists, and test scripts. Given the electrical emphasis, there is also an overview of power characteristics needed to specify and operate test equipment such as load banks and Power Quality Meters (PQMs). The Author's perspective brings firsthand design and commissioning experience forward, with electrical specific examples throughout, such as recommendations for equipment inspections and field observations. The guide also summarizes relevant codes/standards. Having the cited standard/code references available for review as you read is helpful, but otherwise, they are purely supplemental. The Author recommends this text for anyone, novice to professional, in the construction industry with an interest in electrical systems. The guide includes hyperlinks to helpful web addresses, which are more convenient in the e-book format. The reader may still choose to type the addresses into a web browser if they prefer a physical copy of the guide.
