The Intelligent Building Agents (IBA) project is part of the Embedded Intelligence in Buildings Program in the Engineering Laboratory at the National Institute of Standards and Technology (NIST). A key part of the IBA Project is the IBA Laboratory (IBAL), a unique facility consisting of a mixed system of off-the-shelf equipment, including chillers and air handling units, controlled by a data acquisition system and capable of supporting building system optimization research under realistic and reproducible operating conditions. The objective of the IBA Project is, in part, to demonstrate the feasibility of AI approaches for HVAC control in commercial buildings and to provide a research infrastructure suitable for the development and testing of AI technologies for a variety of applications to building systems.
