Yes, though the terms are often used interchangeably. A Building Automation System (BAS) is the broader category encompassing all automated building functions—HVAC, lighting, security, and more. A Building Management System (BMS) typically refers specifically to the software and hardware that monitors and controls HVAC and mechanical systems. In practice, a BMS is a core component within a full BAS framework.
