Visualising real-time in-home energy savings opportunities

到2020年，智能电表和家庭显示器（IHD）将在所有GB家庭（> 2700万）中推出。IHD（实时显示能源消耗和成本）目前提供的机会有限，无法将家庭能源消耗置于背景中，因此，无法充分发挥这些设备通过利用经验证的消费者驱动因素可以实现的客户参与，行为改变和节能的全部潜力。在本项目中，我们将评估一种新型IHD的技术可行性，该IHD提供实时比较消耗，即实时消耗与类似家庭的历史消耗（在一天中的特定时间和季节）的比较，并能够考虑家庭占用率，人口统计学，建筑物特征和电器所有权。在美国，非实时比较消耗反馈已被证明可以为每个家庭额外节省2-3%的能源。这一创新项目将首次在实时环境中应用，有可能每年为英国家庭节省高达3.3亿英镑的电费。

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.
