Criteria are developed to define requirements during the design of industrial ventilation systems. Chapter 2 provides general criteria and Chapters 3 through 10 provide criteria for specific processes. Use the general criteria presented in Chapter 2 along with the applicable specific criteria presented in Chapters 3 through 10 to design the ventilation system. For all other ventilation applications, use the criteria in Chapter 2. Criteria contained in this UFC should be interpreted as the minimum required and should be improved where current technology or situation warrants.

The design concept described in this UFC provides definitive guidance intended to streamline DDC system design and installation leading to maintainable, interoperable, extensible, and non-proprietary control systems. This UFC also contains minimal project requirements. The purpose of this UFC is two-fold, to provide for commonality and compatibility of control systems:
