Energy HOW YOUR DISPLAY AFFECTS WHAT YOU PAY Smart meter displays could be key to changing consumer behaviour S cotland is committed to ambitious climate change targets, for example renewable sources are to meet 50 per cent of our heat, transport and electricity needs by 2030. One way to achieve this goal is to be smarter about the energy we use. A roll-out of smart meters is supposed to herald a revolution in energy consumption habits. But are these meters up to the task? Will access to data influence our behaviour? Researchers from the Scottish Energy Centre attempted to answer these questions by installing smart energy devices in Scottish homes and the results of the study were clear: over a 37-month period the device resulted in reductions of 27 per cent in gas consumption and 21 per cent in electricity consumption compared to households without a smart meter. 21% 27% CONSUMPTION WHEN SMART DEVICE INSTALLED Interested in this project? Dr Jon Stinson The smart home revolution Utility companies are rolling out smart meters – 53 million in the UK by 2020 – but how the information is displayed on these meters is crucial. The Scottish Energy Centre’s research evaluated the effectiveness of the user interface on smart meters by monitoring changes in gas and electricity consumption behaviour before and after device installation. Dr Jon Stinson, from the research team, wanted to get to the bottom of an important problem: “We wanted to engage with occupants and understand their needs and expectations. Is simply providing data enough? Does it prompt change in behaviour and lead to new energy saving habits?” Jon and the team pin-pointed the need for further research on how meters display energy consumption. The smart meters they tested appear to be particularly effective because of the straightforward way they visualise data. What’s next for smart energy technology? How information is displayed is therefore as important as the installation of a smart device in the first instance. By developing exactly how this data is presented, even more radical and sustained behaviour change might be possible. Could connected mobile apps, for example, encourage lower energy consumption? Jon says: “Smart technology is worthless unless it can help us understand exactly how energy is being used and incentivise us to lower – and keep low – both our utility bills and carbon footprint. Truly smart technology should result in smart outcomes: reaching climate change goals through better interface design could well be one.” School of Engineering & the Built Environment [email protected] Find out more on these stories at www.napier.ac.uk/impact 25
