Project description

The GreenSoul project dealt with increasing energy efficiency in public buildings through awareness-raising measures and the development of hardware components for devices (lighting, printer, etc.) to counteract energy-wasting behavior.

The GreenSoul devices have an intelligence that enables them to act autonomously in order to increase energy efficiency. The devices learn from their usage habits and intervene if energy-wasting behavior is detected or suggestions made by the device are not accepted by the users. The GreenSoul devices were equipped with additional hardware in order to avoid the costly replacement and corresponding disposal of devices.

The GreenSoul devices are primarily intended to be used in public buildings, since the employees there do not have to bear the energy costs directly and therefore usually show little interest in saving energy. GreenSoul therefore aims to prove that the combination of awareness-raising measures can lead to behavior change and the use of ICT (information and communication technology) components can lead to energy savings in public buildings.

The analysis of the energy data shows that in most of the pilot plants (in total there were 6 pilot buildings) in which GreenSoul devices have been installed, the average energy consumption per user and day was reduced (up to 14% savings).
