Towards this direction, this paper proposes an integrated methodological framework, determining measures for the case of Greece, which are delivered in the form of a national qualification roadmap. These measures aim to enhance the qualifications of the blue collar workers and generally empower the Greek construction sector. They also facilitate the adherence of Greece to the European Energy Efficiency and Renewable Energy Sources Directives and support the attainment of the national energy objectives for 2020. The methodological framework is initiated with the analysis of the status quo of the Greek building sector and the skills and qualifications gap of the workforce, as well as the identification of the corresponding barriers that impede growth. Subsequently, a number of diverse measures are proposed and evaluated, using a synergy of decision analysis and evaluation methods. The measures that are assessed as of high priority are afterwards specified to concrete actions. Throughout the whole modular procedure, multiple relevant national bodies were actively engaged via transparent consultation procedures and multilateral discussions. Finally, 44 acknowledged organisations declared their endorsement to the roadmap by signing an official letter. http://creativecommons.org/licenses/by/4.0/Renewable and Sustainable Energy Reviews65992-1004 Doukas Haris Ch.
