Lecturer(s):

Samira Rahnama, Hicham Johra, Mahmood Khatibi

Topic, background and motivation for the course:

Despite extensive research and successful implementation of advanced control techniques, like MPC, in other fields, the application of such techniques is still limited in practice in building services engineering. One of the reasons seems to be the lack of knowledge among building service engineers about advanced control methods. There is a growing need for multidisciplinary education on advanced control methods in the built environment.

 Buildings use a large share of total energy use around 35–40% in many countries. In Denmark, buildings account for 40% of the Danish energy use. Building energy-related activities are responsible for the 19% of GHG emissions worldwide. Therefore, it is motivated to investigate the energy saving potential in the building sector. Advanced building control can considerably reduce building energy use. For instance, numerous studies reported that advanced HVAC control can notably reduce energy use and mitigate GHG emissions with average energy savings of 13% to 28%.

The most popular advanced building control solution among the scientific community is Model Predictive Control (MPC) due its proven ability to handle constraints while optimizing the system performance. MPC on the supervisory level can be designed to find energy-efficient or cost-efficient control settings for the local controllers, taking into account the system level characteristics, interactions and comfort constraints. MPC combines building modelling, measurement, disturbance forecasting as well as information from external sources in the optimization formulation in order to find optimal control settings.
