The goal of the Siemens researchers is to develop sensors which act as the sensory organs of buildings and pass on their information to a building management system. Thanks to the tiny watchmen, the management system knows, for example, where aggressive substances have leaked or simply where the lights are to be switched off or the windows opened due to too high a CO₂ level in the air.

Today room climate sensors, air quality sensors and presence sensors can already control the air and light conditions in offices in relation to the number of persons present and, in connection with an optimized control technology, thus save up to 30 percent of the energy consumption for heating, ventilation and air conditioning in comparison with a conventional control and regulating technology.
