Abstract: Because Concrete Core Activation (CCA) actively integrates building mass in the HVAC system, the choice of control strategy and controller settings plays a decisive role in reaching both thermal comfort and low energy use. Although not capable of intrinsically taking into account the system dynamics, conventional feedback control is often applied in CCA buildings. This paper defines the basic characteristics
a CCA-controller should have, by making a sensitivity analysis of the main parameters in a conventional feedback control loop. Without prior knowledge, these parameters are varied, and the behaviour of the controller with the best performance is analysed with respect to energy and thermal comfort. It shows that a performant CCA-controller keeps
the CCA core temperature at a constant level of around 1◦C higher than the lower thermal comfort limit during the whole year. This ensures high thermal comfort and low energy use with a low installed production power.
