PROBLEM: Buildings are responsible for 40 % of energy consumption and 36 % of CO2 emissions in the EU. Monitoring building health and energy consumption ensures that technical installation and the building perform and minimize actual energy consumption. Monitoring sensors are often wireless sensors placed in the building constructions, making battery changes cost expensive.SOLUTION: The patented RePower solution to harvest energy for the sensors makes installation and maintenance easy and cost-efficient; as it is simply clamped-on any power cable, the sensor is plugged on and then running during the sensor lifetime. A typically battery operated sensor using long life Lithium batteries have a cost of 180 € due to the batteries. A RePower’ed sensor have no maintenance cost due to the RePower supply.PPROJECT: This project develops, tests and demonstrates RePower in building installations. RePower is a patented and non-invasive solution to power the different monitoring sensors in an installation, harvesting energy from the outside of multicore power cables. The project has a total of 113 person months and project length of 24 months.IMPACT: Three years after market-launch we expect to distribute 1.4 million RePower driven units annual, to public and commercial buildings, generating 256 new employees at Xtel, ReMoni and our partners. MARKET:Sales is established through international service companies, distributors, and OEM customers, using our already established sales network. The global market potential for new wireless sensors nodes in 2020 is estimated to 15 billion units a year for the groing market of the Internet of Things (IoT). EU RELEVANCE: RePower has the opportunity to be an industrial enabler for the EU IoT development, and thereby strength the European competitiveness , with a novel solution to solve the power issue of wireless sensors.
