How to Use This Book

Abstract

There are two current and related acknowledgements within the HVAC industry. The first is a recognition of the necessity of proper validation and verification of today’s powerful DDC control systems. Closer attention must be given during the shop drawing review process that the DDC system meets the design intent and satisfies the needs of the end user. The second acknowledgement is of the need, due to the increased sophistication of all mechanical system components, including the DDC system, for proper commissioning of complete mechanical installations. It is no longer profitable, nor acceptable, to simply “start-up” and “turn over” systems without verifying that performance conforms to thedesign intent.The common link between these two industry efforts is the DDC system.
