On 13 and 14 December 2017, in Minsk, an important convention was organized for the Covenant of Mayors involving six countries of the Eastern Partnership (Armenia, Azerbaijan, Belarus, Georgia, Moldova and Ukraine). Objective of the meeting: sharing experiences, best practices, ideas and innovations on the topics of energy saving and energy management. The presence of Reverberi Enetec at this important meeting was requested by EnergyCities: the adaptive lighting system of the LIFE-DIADEME project, in fact, aroused much interest. Presentations have been displayed by introducing energy “policies”, projects and concrete case studies, allowing the exchange of “good practices” with respect to specific sectors. LIFE-DIADEME illustrated the expected objectives of the project, generating enthusiastic consensus.
