Final Report Abstract

The overall aim of the project was the development of efficient controllers for the energy efficient HVAC of buildings. These controllers should be able to incorporate possible changes e.g. in outside temperature (due to weather changes). This problem is very challenging because the underlying physics leads to complex, large-scale problems which have to be solved numerically very often. To overcome these difficulties we develop an algorithmic optimal control strategy, where the interplay between the optimization methods and the simplification of the physical model (by linearization and reduced-order approaches) was done in an efficient and certified way.
