Living Lab Energy Campus experimental buildings (LLEC)
In the Helmholtz Research Infrastructure Living Lab Energy Campus the construction of three experimental buildings with identical building envelope and generous instrumentation, but different controllable heating systems, was realized. The three experimental buildings enable research on a self-adjusting process control for the network-based regulation of building heating systems and their validation in a real-world experiment. Due to an improved process control, all heating systems equipped with such modern controllers directly save energy. Electricity-based heating systems with network-based controls also provide system services in the electricity network.
