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:
- Commonality. Describes a definitive methodology for the design of building-level control systems and strategies (primarily for HVAC) where the intent is to achieve at least a degree of commonality in systems designed and procured through different channels. Common sequences of operation are specified in UFGS 23 09 93.
- Compatibility. Describes a definitive methodology to obtain multi-vendor systems that can communicate and interoperate with each other and with a supervisory monitoring and control system such as a basewide UMCS through the use of an Open communications protocol.
