Abstract: As a part of the EU strategy to reduce energy demands of the building sector in order to achieve climate-neutral levels by 2050, energy renovation is required with a rate of 3% of the total floor area of occupied heated and/or cooled buildings. The EPBD requires that buildings should undergo major renovation, in which a building’s final energy demand for heating could be reduced by 50% to 80%. The ambitious goals set up by the EU present a major challenge for professionals on field to take charge of carrying out big number of energy renovations in short time. This study aims to present a novel methodology that facilitates the process of creating detailed simulation models and the application of different Energy Conservation Measures (ECM). This methodology constitutes 5 mains steps, from the acquisition of existing building information to site visits, calibration, application of ECM, and calculating the Net Present Value (NPV) of the taken measures. The methodology has been validated through application on several buildings with different sizes and functions.
