Applying the EP label tools for energy certification of buildings in Greece

The primary aim of the EP label project was to develop a methodology for energy benchmarking and certification of buildings, based on Operational Ratings, to address the EPBD Article 7.3 requirement for Public Buildings over 1,000 m to display an Energy Performance Certificate.Within the EP label project, an easy-to-use yet robust system for building owners, occupiers and managers has been developed that produces a provisional energy performancecertificate in advance of national legislative requirements being finalised in each Member State.Energy assessment and certification have been approachedin a series of progressive levels, increasingly detailed but requiring more stringent verification procedures,the so-called graduated response methodology. The concept is that assessments can be at different levelsof detail within a cohesive framework.The system has been developed by leading experts on the field of energy performance of buildings, both as an Excel program and a web-based version (EPLabel Online). An impressive feature of the software is that with EC funding it is working with the data and languages of fifteen European countries. It is proposed as a reliable and pragmatic way for benchmarking and production of energy certificates which offers sufficient flexibility to support harmonization between the differentmember states.
