An effective training took place on the 20^th of June 2023 in Greece, during which the Photovoltaic (PV), Energy Storage Solution (ESS) and Demand Side Management (DSM) were presented. The participants were the employees of two different municipalities in Greece and they were mainly engineers and financial managers. One of the mayors also joined the training. 

The short training gave an overview of the steps towards the energy transformation of public buildings into high self-sufficiency buildings, using PVs, batteries, and load management. During the first part of the training there was a short presentation of BERLIN project, the current situation of renewables and storage systems in Greece, the financial tools that exist, the lessons learnt from the BERLIN pilots and the energy performance of the PV+ESS+DSM solution. During the second part, the BERLIN online tool was demonstrated, by explaining all its capabilities and by running some indicative case studies for public buildings in Greece. The training concluded on the roadmaps that facilitate the adoption of PV+ESS+DSM in public buildings targeting mainly energy managers and engineers in key positions of public institutions.
