Intelligent Building Agents Laboratory: Hydronic System Design



Amanda J. Pertzborn


Achieving national goals of net zero energy buildings requires substantial reduction in the energy consumption of commercial building systems. In 2015, commercial buildings consumed 18 % of the total energy consumed in the U.S. [1]. Although significant progress has been made in the integration of building control systems through the development of standard communication protocols, such as BACnet and BACnet/IP, little progress has been made in making them “intelligent” about optimizing building system-level performance. The purpose of this project is to demonstrate the potential for distributed, intelligent software agents to perform this optimization and to develop a research infrastructure suitable for development and testing of advanced agent-based optimization techniques that can improve the energy and comfort performance of building systems. Towards that goal, the Intelligent Building Agents Laboratory (IBAL) has been constructed to act as a testbed for these intelligent control algorithms. This note describes the design of a portion of that facility.
