Multisensor system for energy consumption awareness in large buildings

Energy consumption awareness is an important first step to reduce carbon emissions. While real time fuel consumption indicators in motor vehicles are widespread, the instant energy consumption of buildings is typically unknown. This paper presents a multisensor system for energy consumption awareness in large, existing buildings that offers real time consumption values of all energy types at low-costs and with little installation efforts. The system aims at educating, motivating and supporting the inhabitants to save energy and reduce their carbon footprint. Sensor data fusion is used to enhance measurement quality while keeping costs low.
