After the kick off meeting held in Basovizza (Trieste, Italy) last 9 and 10 December 2014, the BU.G.S. project started its activities. Project partners are actively working on the collection of companies and institutional data related to the use of renewable energy sources, building energy performance and training obligations in the construction field in order to set up a sector study and analysis. Aim of this activity will be the definition of a software for a tailor made evaluation of skills gaps to be detected and overcome in the 4 project countries: Italy, Austria, Slovenia and Croatia. The data mining software is expected to be available to public in the second half of the year.
