The evidence we have been waiting for: KNX does save energy and now we proof it
Studies revealed by the KNX Association show how networked home and building control based on KNX allows up to 50% energy savings.
These are the achieved conclusions:
1) Institute for Building and Energy Systems at Biberach University of Applied Sciences: “Particularly automation functions, which present a high degree of energy-saving potential by combining various individual trades, can today only be achieved using modern building system technology based on bus and communication systems.”
2) Bremen Univesity of Applied Sciences: based on a four-year series of measurements, the use of KNX control was found to reduce energy consumption by an impressive 50%. It is thus clear that the expenditure in building automation system has quick payback.
The research project conducted at this University shows Energy saving with KNX on the extent to which energy savings based on the example of heating energy. The newly constructed Centre for Informatics and media Technologies (ZIMT) has been fitted with KNX controls and equipment for regulating heating and lighting. The data collected has been evaluated, and comparisons made between “normal” operation and “automation” mode. The building has a specific energy consumption of 60-75 kWh/m2a. Two identical classrooms were selected as test rooms. One was fitted with a conventional installation, and the second with KNX control.
The above mentioned University calculated that, with an annual energy consumption of 230,000 kWh for lighting alone, the investment would pay itself back after just one year with a KNX bus control. Ultimately it is not just the owners/operators and investors who benefit from the reduced energy consumption: the climate does as well.
In summary, KNX allows the following energy savings to be made:
up to 40% with KNX shutter control
up to 50% with KNX single room control
up to 60% with KNX lighting control
up to 60% with KNX ventilation control
