The 3rd project meeting and the mid-term review was held in September 19th and 20th at Palazzo Nervegna in Brindisi. The REEHUB project aims to create 4 hubs in the 4 regions of the program. The hubs will establish a network of centers for energy efficiency and sustainable building design with a scientific-technological approach supported by ENEA. The responsible WP Partners presented the Hubs and the instrumentation made available to monitor the energy performance of these centers. The training activities carried out by ENEA's technicians were necessary to analyze the energy savings potential of the buildings with the aim to share a common methodological approach for the Mediterranean regions. MIE, BIRD, ENEA, DiTNE, Municipality of Agnone and the University of Montenegro presented the progress of the WP for which they are responsible and the possible future improvements.
