Big data reduces energy waste for King's College London

Signal of change / Big data reduces energy waste for King's College London

By Laura Picot / 23 Jun 2015

King's College London is saving an estimated 2,500 tonnes of CO2 per year, and £390,000 in energy bills, by installing a cloud-based energy-tracking device from UK-based Demand Logic. The company reduces the energy requirements of large commercial buildings by tapping into the building management system which monitors heating, cooling and lighting. A small data acquisition device is installed which can track the performance of every appliance in the building, from major plant items such as boilers to individual air conditioning units. Energy inefficiencies, such as faulty equipment or a room being simultaneously heated and cooled, are identified and the information is then shared online with building maintenance staff who can take action to resolve the issue.

So what?

According to Breaking Energy, the average commercial building wastes 30% of its energy use. Demand Logic’s device is an efficient way to make use of data that is already being collected but is not analysed in detail or put to use.

The technology typically reduces building energy use by 10%, resulting in a lower carbon footprint and energy bill. So far, the company estimates that is has saved 2,750 tonnes of CO2 per year from commercial buildings and there is potential for the device to be installed in a wider range of buildings in the future. “The magnitude of savings possible is staggering”, says Demand Logic CEO Joe Short.

The company recently won a prestigious Ashden Award for pioneering sustainable energy organisations.
