The NIST Virtual Cybernetic Building Testbed (VCBT) is a whole building emulator designed with enough flexibility to be capable of reproducibly simulating normal operation and a variety of faulty and hazardous conditions that might occur in a "cybernetic building", where numerous building control systems are integrated together and with outside entities such as utility providers. It serves as a testbed for investigating the interactions between integrated building systems and a wide range of issues important to the development of cybernetic building technology including:
- Automated commissioning of building systems;
- Automated fault detection and diagnostics (FDD) of building systems and components;
- Optimization strategies for interacting building systems;
- Communication and interaction between building systems and utility providers to manage energy loads and respond to real-time price fluctuations;
- Development of decision support tools to aid emergency responders; and
- Extension of BACnet capabilities to new applications.
The VCBT control hardware consists of BACnet products from multiple companies that are used for HVAC control, lighting control, physical access control, and fire detection. The BACnet network topology is an internetwork of all network types commonly found in BACnet systems.
