Computer-based monitoring and control systems offer numerous application possibilities that can lead to substantial energy savings, reduced maintenance costs, enhanced performance, and greater human comfort. Direct Digital Control of Building Systems, written by the developer and manager of Cornell University's massive digital control system, provides thorough coverage of the design methodology needed to create complete and efficient HVAC control systems and to upgrade existing analog technology for such enclosed spaces as buildings, transportation systems, and other controlled environments. It emphasizes throughout the high performance, reliability, and reduced cost of modern digital sensors, control devices, microprocessors, computer memory, and other electronic components. Direct Digital Control of Building Systems goes on to provide an extensive case study of effective DDC system design... step-by-step insight into how to specify, install, commission, operate, and maintain a DDC system... and a concise evaluation of DDC's future. Also included are numerous references to various standards and documents that form much of the foundation of DDC technology, and a listing of available DDC hardware and software suppliers. The many advantages of digital controls in HVAC systems have been amply documented in recent years. Now there's a comprehensive volume that provides today's mechanical engineers with the practical tools needed to effectively realize such systems - Newman's Direct Digital Control of Building Systems.
