Lower costs, more climate protection
The Covid 19 pandemic confronted BBS II with special challenges during the measurement period. Regular ventilation of the classrooms generally increased the heating energy demand. Under these conditions, the strengths of the smart technology came into their own, so the trial could hardly have come at a better time for the school.
In the end, the figures speak for themselves: the intelligent individual room control by Homematic IP reduced the energy consumption of the smartly heated part of the building by 31 % compared to conventional heating. By simply retrofitting smart radiator thermostats and window contacts, the energy consumption - and thus also the CO2 emissions - could be reduced by almost a third; without any complex and expensive renovation measures or even new buildings.
The actual savings are even greater. Why? The smart part of the building could hardly benefit from the natural heating by solar radiation due to its north-west location - in contrast to the conventionally heated south-east wing, which was fully illuminated by the sun, especially during teaching time, from morning to early afternoon. If you include the solar yield, the advantage of the intelligent individual room control becomes even clearer. This even results in a potential energy saving of around 40 %.
