What would the energy transition be without consumers? In this laboratory, living and working conditions are compared and evaluated. The data provides valuable insights and enables realistic research.
In the Helmholtz Research Infrastructure (FIS) Living Lab Energy Campus, three experimental buildings were constructed with identical building shells and extensive instrumentation, but with different controllable heating systems. The three experimental buildings enable research into self-adjusting process control for grid-friendly control of building heating systems and their validation in a real-part experiment. Thanks to improved process control, all heating systems equipped with such modern controllers save energy directly. Electricity-based heating systems with grid-supporting controls also provide system services in the electricity grid.
