The aim of this research is to quantify the role of socio-economic and individual preferences on energy performance gap in the residential sector. First, using a two-steps discrete-continuous choice method, we study the probability to live in an energy-efficient dwelling in order to identify the weight of household's characteristics and individuals' preferences on energy consumption. In the second part, we identify the drivers of the energy performance gap using a quantile regression. Quantile regression analysis lets us to tease out the effects of preferences on entire distribution of energy performance gap spectrum instead of focusing on the conditionnal average. The purpose is to explain extreme behaviors regarding energy use. As a result, this research shows that individual characteristics contribute to an important part of the energy performance gap. In such a context, some warnings to public authorities are provided regarding the fair assesment of energy savings benefits after thermal retrofits.
