How V2B works
The approved explanation should connect physical systems, communications, data, security, and operating responsibility.
Vehicle-to-Building uses a bidirectional vehicle and compatible charging and transfer equipment to supply building loads, support a microgrid, or reduce site demand. It is narrower than V2G because discharged energy serves a facility rather than being exported as a grid service. Electrical design, controls, interconnection, and available vehicle energy limit operation.

ISO 15118-20
ISO 15118-20 defines second-generation charging messages, including bidirectional power-transfer communication. It matters to V2X because it gives independently developed systems a common technical contract.
