Energy Efficiency Calculation

Examples for Energy Saving Potentials

The new ABB Energy Efficiency Tool makes it easy to find out Energy saving and efficiency potential through the use of Smart Home and Intelligent Building Control System KNX. The calculation is based on the German Standard DIN V 18599, which is the basis for the energy performance certification of buildings.

Building system engineering supported by intelligent and networked room and building controllers (lighting, sun protection, heating, ventilation and air conditioning as well as the other building engineering systems) contribute significantly to conservative and requirement-based energy use. The worldwide standard for KNX technology enables energy savings in the double-figure percentage range and also provides enhanced flexibility with planning and implementation, a high level of investment protection and a high level of availability.
