Visualising real-time in-home energy savings opportunities

Smart meters and in-home displays (IHD) are being rolled out across all GB homes (>27 million) by 2020. IHDs (which display energy consumption and cost in real-time) currently offer limited opportunities to put household energy consumption in context, and as such, fail to deliver the full potential for customer engagement, behavioural change and energy savings that these devices could achieve by leveraging proven consumer drivers. In this project, we will assess the technical feasibility of a new type of IHD which provides real-time comparative consumption, i.e. how real-time consumption compares to the historical consumption of similar households (at that specific time of day and season) with the ability to take into account household occupancy, demographics, building characteristics and appliance ownership. Non real-time comparative consumption feedback has been shown in the US to offer an additional 2-3% energy saving per household. This innovative project will be the first time this is applied in a real-time context with the potential to save GB households as much as £330 million annually on their electricity bills.
