The MPC-GT project brought thogether a transdisciplinary team of SMEs, large industry and research institutes, experienced in research and application of design and control systems in the combined building and energy world. Based on prior research, supported by (joint) EU and national projects, and practical experience the bottlenecks where identified that prevent at this moment a real breakthrough of geothermal heat pumps (GEO-HP) combined with thermally activated building systems (TABS)-GEOTABS. Solutions, which need to be implemented in an integrated way, were identified and sufficient proof of concept was gathered to join forces in a RIA.
