The CalFlexHub Symposium 2024 featured speakers from across the Hub’s ecosystem. This session will explore the critical role of communication, control, and interoperability in enabling load flexibility in small buildings. As California moves toward a more dynamic energy grid, ensuring that small buildings can effectively integrate and manage flexible energy loads is essential for the state’s energy transition. Panelists will discuss the challenges and opportunities in developing interoperable systems that allow for seamless communication between devices, control systems, and the grid. The conversation will also cover the role of emerging standards and protocols in improving the performance and scalability of smart building technologies, contributing to California’s broader energy goals.
