Between Nucleus and Cytoplasm

Over two million commercial buildings in the U.S. are controlled by direct digital control (DDC) or like systems, and the trend is toward totally intelligent buildings by the end of this century. Even though DDC is quickly replacing traditional methods of controlling temperature, humidity, lighting, security, and life safety in commercial office buildings, guidance on the fundamentals, applications, and economics of DDC has been difficult to find. Applications-oriented and written from a practical point of view, Direct Digital Control for Building HVAC Systems is one of the first books to familiarize the reader with 'how to' specify, purchase, and support microprocessor-based building control systems. Even those with limited knowledge of digital technology will be enabled to implement DDC systems, thanks to down-to-earth descriptions of the purpose, benefits, and limitations, design, construction, operation, and cost of these systems. Especially valuable are the book's methods for interfacing digital control with existing HVAC systems. Mechanical engineers involved in the design of building control systems, mechanical estimators, facilities, plant, and building operations and maintenance personnel in both the public and private sector will all find this book a valuable resource.
