Review on methodologies for energy benchmarking, rating and classification of buildingsReview on methodologies for energy benchmarking, rating and classification of buildings Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-152011enThe energy benchmarking, rating and classification of buildings are necessary procedures for energy certification scheme adoption, energy regulation establishment, energy-efficiency promotion and energy consumption reduction, according to the Directive 2002/91/EC and its implementation in EU member states. The aim of this paper is to investigate and present research works, tools and programs focused on energy benchmarking methods, energy rating procedures and classification schemes for the building sector. The European Committee for Standardization method of benchmarking and rating for buildings are analyzed, as well as a proposed integrated classification method based on the application of clustering techniques to virtual building data sets of office buildings in Greece.http://creativecommons.org/licenses/by/4.0/Journal of Advances in Building Energy Research151-18 Stavrakakis Georgios Σταυρακακης Γεωργιος Kolokotsa Dionysia Κολοκοτσα Διονυσια Nikolaou Theodoros Νικολαου Θεοδωρος Taylor & Francis Energy efficiency in buildings
