| Summary/Abstract |
Field experiments have shown that information nudging can help households to save energy, however, the effectiveness varies depending on aspects such as information content, delivery mode and study area. This article evaluates the impacts of information nudges on residential electricity consumption with a randomized field experiment. This opt-in experiment was conducted in Finland. Information was administered via monthly email newsletters and an online energy service platform. The aim is to find out whether i) energy saving tips combined with and without online energy service platform providing electricity consumption information, and ii) peer comparisons (i.e., social norm) influence households’ electricity consumption. The results show a high seasonal variation in the treatment effects within the groups who were registered users of the online energy service platform. Those with access to usage feedback and versatile energy savings tips (without the social norm comparisons) reduced their electricity consumption around 10% in wintertime. The results imply challenges in encouraging energy saving behavior among households less interested in following their electricity consumption.

| Summary/Abstract |
Since the Paris Agreement of 2015, 195 countries, including Belgium, have committed themselves to keep the earth from becoming warmer than 1,5 °C since pre-industrial levels. By building and renovating in a more sustainable way, greenhouse gasses can be contained. Previous studies already demonstrated the influence and decisive role of the individual homeowner in energy retrofitting. Recent research highlights that energy efficient renovations are not a solo slim game by the homeowner itself, but a collaboration between various intermediaries and the homeowner. By conducting in-depth interviews, with a focus on the installation of heat pump technology, we identified a series of drivers and barriers that intermediaries experience when installing heat pumps. These drivers and barriers where structured and analyzed according to the “Alphabet theory-framework”. As a result, this paper provides four concrete propositions that can be applied by policymakers that face similar challenges in the transition to climate neutral buildings: (1) Intermediaries should be aided and supported in recommending heat pumps to private homeowners, (2) Inform, guide, and sensitize intermediaries about up-to-date heat pump installations, (3) Sensitize homeowners by providing non-complex information in a centralized and accessible place, (4) Facilitate knowledge transfer between intermediaries who offer their services to the same consumers, transcending time.
