This book discusses building commissioning, which is the process of certifying that a new facility meets the required specifications. As buildings have become more complex, the traditional methods for building start-up and final acceptance have been proven inadequate, and building commissioning has been developed, which often necessitates the use of outside consultants to monitor the process. One-half of the guide details the roles of the consultant, contractor, test engineer, commissioning agent, and owner. It describes the process, the needed equipment testing, systems functional performance testing, scheduling, documentation, training, costs, and the process of hiring a commissioning agent. Chapters include an overview of commissioning and discussions of: approaches to commissioning, design requirements, contract documents requirements, the steps of the commissioning process, selecting the commissioning agent, and the costs of commissioning. A case study of commissioning a science building is provided. The other half of the guide consists of a description of terms and 15 different guide specifications in the form of detailed documentation and testing checklists, divided to indicate specific tasks and tests (e.g., general, mechanical, electrical facility startup/commissioning; commissioning--general requirements; HVAC systems, supply air systems, exhaust air systems, environmental control systems, etc.) (JLS)
