Scientific study undertaken on the basis of the DIN V 18599 Data and facts relating to bus technology as well as room and building automation

In 2008, the Biberach University of Applied Sciences, commissioned by ABB, carried out a study on the issue of “Energy saving and efficiency potential through the use of bus technology as well as room and building automation”.

The efficiency of ABB i-bus® KNX components was scientifically studied on the basis of the DIN V 18599. The usage profile “open-plan office” in a classic example building served as the research project.

The DIN V 18599 was drawn up by the German DIN standards committee for heating and ventilation as well as lighting. The standard was introduced to implement the EC directive 2002/91/EC “Energy Performance of Buildings Directive”, and in Germany it serves as the basis for issuing energy certificates for buildings. From the 1st of July 2009, all non- residential buildings in Germany require an energy certificate, if they are re-let, sold or leased. The building owners must submit this document to any interested party on request. In public buildings with more than 1,000 square meters of floor space, the energy certificate must also be visibly displayed.
