ABB Centre in Odense, Denmark: 13 % energy savings through KNX technology The building incorporates 123 rooms on three floors.

Museum “Arte Moderna” in Rovereto, Italy: About 28 % energy savings through KNX technology The museum is one of the most important exhibitors of contemporary art in Italy. ABB i-bus® KNX technology is used primarily for control of the lighting. The individual functions are automatic lighting control, timer control and light scenes.

The KNX installation consists of 14 lines with a total of 645 ABB i-bus® KNX components.

In addition to automation of the heating and cooling systems (presence-dependent, time controlled), particular emphasis was placed on constant lighting control.

In a comparison to 2006 and after installation of KNX in 2007, an energy saving of about 28 % can be seen. The power consumption values have been reduced by more than 38,000 kWh per month.

Proven facts after one year of operation: In the open-plan offices, a saving of 13 % of the electrical energy could be verified for the lighting after a comparison of the previous and current consumption measurements. In the measured area, this corresponds to a saving of 29 kWh per day or (at a kWh price of 0.15 € ) 4.35 Euro per day!

The museum has saved almost 80,000 Euro in the first year of usage of the KNX system.
