New regulations in many countries demand that by 2050 the residential sector will become carbon neutral. To achieve this objective, energy efficiency renovations (EER) in the housing sector are key to reduce energy consumption and carbon emissions. There are many factors that might influence an EER decision which are classified as barriers and motivations. This research aims to understand and classify the underlying motivations and barriers for EER. A bibliographical study through the analysis of articles and institutional/regulatory frameworks has been consulted to identify and classify the barriers and motivations for EER. The research indicated that these are mainly sub- classified as economic and non-economic factors [2]. Different methodologies have been applied to the study of such barriers and motivations to understand the decision-making process of property-owners to renovate their homes. Bibliometric networks have been a useful tool to understand thematic areas for modelling decisions, while other authors have analyzed the subject through models of energy consumption behavior [3]. Among the main economic barriers are the payoff period for the investment, upfront costs and investment and aversion to loan, while for economic motivations the most named are the increase of energy prices and the increase of the property value. Misinformation and uninterest are among the most named non-economic barriers, but reduce on energy consumption, lower environmental impacts, and improve of thermal, acoustic and noise comfort are among the most named non-economic motivations. The identification and classification of the main economic and non-economic barriers and motivations for EER are a useful input to build EER models and to compare them with the trends that can be found through the analysis of the open data. The second stage of this research aims to define a quantitative methodology to analyze the potential of large-scale EER using open-data and to study the impacts of these barriers and motivations in France.
