How do French social housing tenants interpret normative descriptive feedback connected with energy? / ¿Cómo interpretan los inquilinos de vivienda social en Francia los mensajes normativos descriptivos respecto al consumo de energía?

Abstract Energy-efficient houses are designed to reduce electricity. However, a gap between theoretical and actual energy performance of buildings is often observed. Achieving energy efficiency through regulatory norms is insufficient, and ways must be found to change people’s behaviours. In this line, normative feedback could be a powerful tool to reduce residential energy consumption. In the present research, 14 low-energy buildings were equipped to measure energy consumption. Their occupants received descriptive normative messages used to promote household energy saving. We were interested in the quantitative impact of normative feedback on household consumption, but also in the way in which these households receive the information linked to normative feedback and how they adapt to it. The results showed that energy-efficient houses are not an environment in which people could learn new practices if they do not have knowledgeable pre-requisites. A normative feedback can help change habits only for people who have the knowledge regarding energy issues that allows them to understand the feedback. For most households, the information is not understood and does not lead to behavioural change.
