Smart meters only yield small energy savings, research finds

Smart meters are capable of only modestly reducing residential energy demand and yield unimpressive energy savings, recent research from the University of Waterloo in Ontario, Canada, has been able to suggest.

The study compared data for nine months before and after the new features were introduced in November 2011 by a utility company which serves more than 20,000 household customers.

It suggests smart technology only modestly reduced residential energy demand among users during the most expensive peak periods, dropping just 2.6% during on-peak periods and 2.4% during mid-peak periods following the change.

Catherine Rosenberg, Professor of Electrical and Computer Engineering, said: “Is it enough? Of that I’m not sure. We don’t have the data to decide if these kinds of savings warrant the use of smart meters.”

HeatingSave – leading developers of Smart Energy Monitoring and Management Systems

The HeatingSave Building Energy Monitor is a wireless management system that collects information from sensors placed in a building. It is unobtrusive and causes minimal disruption during installation. The system collects internal and external temperature data, along with information on how the heating system works and details of energy use. It also monitors the way a building is used in terms of its occupancy and the occupants’ activities and lifestyles.

Using a password protected standard WiFi connection, sensors can quickly be set up to review and quantitatively analyse the data with user-friendly software graphics, via a laptop, PC, mobile phone or tablet-based device.

A cable connection to the building router also enables data to be uploaded to HeatingSave’s cloud storage servers, where it can be analysed by sophisticated software. This provides a clear understanding of the real impact of energy efficiency measures, for example through pre-installation analysis and post-installation monitoring.

Building owners can access their energy usage details online to help them manage energy use more efficiently. This information is presented using a dashboard system that provides consolidated and drill down views of the energy use data.

Uniquely to HeatingSave, with only a few modifications, the Energy Monitor can also be used for controlling heating and electricity consumption within a dwelling, for even better savings.
