The consumption of buildings is strongly influenced by the behavior of its occupants. Therefore, it is important to make users aware of their consumption and help them reduce it.
THE4BEES project presented in this publication aims to raise users’ awareness of building energy consumption and to optimize comfort and energy efficiency through better user -building interaction. The designed method gives an important role to the user, while increasing use and acceptance, which is sometimes difficult to achieve with fully automatic solutions.
To achieve this, a user building interface (ICT application on a tablet) was developed. This tool provides occupants of two monitored offices with information on their electricity and heating consumption, comfort indicators (temperature and air quality), light control and hints & tips on how to improve their behavior.
The implemented architecture system is multiprotocol in order to communicate with sensors and actuators of any type and any manufacturer. A 32 weeks measurement campaign has led to a significant reduction in the electrical consumption of lights and electrical appliances. Air quality in the working environment was also improved thanks to the user interface.
This research highlighted that including occupants early in the design process of a user-building interface that meet their expectations is a good way to inform them and make them realize the impact of their behavior on the energy consumption.
