Christian Ghiaus is professor at INSA Lyon, France. He has been working over 30 years on intelligent control of energy and air quality in the build environment with contribution to fuzzy, neural networks, and model predictive control. He developed a method for dynamic models for building energy management based on modelling heat transfer with thermal networks and their transformation in state–space representation. He also pioneered computational psychrometric techniques by defining the sizing of HVAC systems as a control problem. These methods are taught at master level in universities in France and Switzerland. In teaching, he uses extensively personalized tests (for which he developed a method in Python for generating cloze questions for MOODLE) and group projects.
