| dc.description.abstract | Residential buildings account for a significant share of final energy consumption and associated emissions. Therefore, it is essential to rethink current practices to achieve energy transition. This study explores energy sufficiency (ES) in the residential sector, combining an analysis of good practice guides with a survey and experimental monitoring. The research begins with an analysis of national guides promoting good consumption practices, namely ES measures, identifying typical recommendations. This analysis was followed by a survey aimed to understand consumers’ habits, perceptions, and awareness regarding ES measures. Based on this, an experimental component was carried out to assess how the implementation of ES measures influences energy consumption. The measurements focused on quantifying the impact of changes in washing cycles in washing machines and dishwashers and on the temperature setpoint of water heaters. From the guides analysis, it was found that the measures presented in them tend to converge around the same set of measures and are repeated in most documents. The survey responses showed that many of these measures are already being adopted by users, indicating a general awareness, and acceptance of ES measures. However, certain practices still allow for improvement. Regarding the experimental phase, washing machines consistently consumed less energy at lower washing temperatures. For dishwashing, the short program proved to be the least energy consuming, even surpassing the ECO program usually recommended, implying the need to review and update the guides. In the case of the water heater, it was observed that reducing the temperature settings led to significant reductions in energy consumption, impacting both active consumption and thermal losses. Overall, these findings demonstrate that making even minor adjustments in appliance usage can lead to meaningful energy savings. | en |
