Based on our extensive experience developing low-cost sensing infrastructures and long term deployment of ecofeedback systems, we discuss the possibility of unobtrusively inferring domestic activities from the overall aggregated energy consumption of households. We then postulate how the combination of this information with daily household activities could lead to more effective and meaningful ways to re-aggregate residential energy consumption for the purpose of ecofeedback. Here we briefly present a practical approach towards this new research direction that leverages HCI related methods, in particular using the day reconstruction method to provide semi-supervised approaches for automatic detection of household activities.engPromoting energy conservationEnergy conservationOpportunistic energy sensingEnergy sensing.Faculdade de Ciências Exatas e da EngenhariaTowards using Low-Cost Opportunistic Energy Sensing for Promoting Energy Conservationconference object
