Research Data

In 2013, the German Fraunhofer Institute has conducted an energy-saving simulation study on heating control system using human presence detection and weather forecasting technology. According to the study, the housing samples in the test can save an average up to 24% in energy by switching the heating on and off according to human presence detection alone. The Brilliant Energy Saver energy saving solution is designed based on this concept.
