Abstract

Abstract This study aims to reveal the effectiveness of energy efficiency advice in the residential sector by using the push notification function of a smartphone app. The app was provided to approximately 1,700 households, who were recruited by an opt-in method, in the Kanto region where the temperate climate in eastern Japan. We conducted randomized controlled trials to evaluate the impact of push notifications with energy efficiency advice. The proposed energy efficiency advice used the data of electricity consumption and attributes as well as behavioral science’s “nudge” approach. The results indicate that the energy efficiency advice reduced electricity consumption by 1.3%, which is statistically significant. Furthermore, the implementation rates had increased for some of the energy-efficiency behaviors that were mentioned in the advice. Additionally, the opening ratios of the push notifications were improved 1.2 and 1.3 times using personalized sentences and adjusting the timing of the push notifications, respectively. These results indicated that personalization of the push notifications could increase the number of users who check the advice. An increase in the energy efficiency rate was observed among households who checked the advice on the standby screen of the smartphone and the dialog and notification list screen in the app. Although this study used relatively simple logic to deliver personalized energy efficiency advice, the results suggest that utilizing smartphones and various data, as well as making communication more interactive between the users and service providers, could effectively induce energy-efficient behavior.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
