Building Energy Management, Stochastic MPC and a Surprise


F. Oldewurtel

IfA Internal Seminar Series

One of the most critical challenges facing society today is climate change and thus the need to realize massive energy savings. Since buildings account for the largest fraction in total energy use, energy efficient building climate control can have an important contribution. The talk is divided into three parts. In the first part, we will give a short overview of building climate control and the activities in the OptiControl-Project ( The work done in this area motivates to investigate stochastic MPC methods for building climate control. The second part deals with the work to be presented at CDC'08 about a tractable approximation of chance constrained stochastic MPC based on affine disturbance feedback. We consider a discrete-time linear system subject to stochastic disturbances and provide a method for efficiently finding control policies that ensure to satisfy a given set of polytopic input constraints and uncertain linear constraints on the state, but which is sufficiently computationally tractable that it is also applicable to large-scale systems such as for example buildings. Finally, we will give an overview of current research questions.
