Summary
👤
Senior🎓
Top SchoolJianjun Hu is an engineering researcher with 9 years of experience specializing in whole-building energy simulation, building energy management systems, airflow modeling, shading control, and HVAC design. Based in Berkeley and currently a Researcher III at Berkeley Lab, he combines academic rigor—Ph.D. training and years at Purdue—with hands-on industry work on super-tall buildings and virtual testbeds at United Technologies Research Center. He contributes to open-source building simulation tooling, notably the Modelica Buildings library, where he has merged features spanning model, C backend, Python scripts and documentation. Jianjun’s work bridges control theory and practical implementation—developing MPC frameworks, integrated energy-airflow prediction models, and efficient online optimizers—enabling real-world mixed-mode and high-rise HVAC solutions. Colleagues rely on him for turning complex multiphysics simulations into deployable control systems that improve building performance and occupant comfort.
