Abstract: Many control approaches have been developed for large solar collector fields but a few studies on Solar Combi-System (SCS) exist for domestic uses. This work presents a simple yet effective control algorithm for SCS coupled to NZEB buildings using a feed forward cascade PID control. Existing works tend to use simplified simulation tools which do not account for efficiency enhancement contribution of a detailed control. Using Modelica, a dynamic control was coupled to a SCS and results show high performance even in harsh climate as Strasbourg. As shown in this paper NZEB should then consider solar energy for space heating too and not only as a way to provide domestic hot water.
