The document describes the Energy Villab Model called VILAGO, which was implemented by GOLEA. VILAGO is a virtual laboratory located in Nova Gorica that aims to (1) improve energy efficiency in public buildings, (2) monitor energy usage of public buildings, and (3) promote energy retrofitting of public buildings through public-private partnerships. The mission of VILAGO is to become a reference environment for monitoring energy usage of public buildings. It was officially established in 2012. VILAGO aims to create an innovative environment to retrofit public buildings and measure renewable energy and energy efficiency through cooperation between the public sector, ESCOs, schools, universities and other stakeholders.
