The work was carried out by local installer iElektro, by Per Even Sandnes Pettersen and Helge Ivar Orset. They explain that energy savings were a motivating factor for this investment. “For this
reason, we measured the energy consumption of the old installation for 27 days prior to the change, and then we measured the energy consumption for a similar period of time after the new solution was installed.”

The result was astonishing: The old installation used a total of 30,68KWh/ day. With the new solution the energy consumption was reduced to 6:02KWh/ day. This is a major savings on the electricity bill for the university. In addition, there is no maintenance cost since there are no fluorescent tubes that need to be replaced. The modern LED light sources have a very
The Zigbee technology is a protocol controlling the luminaires, enabling them to communicate with each other. Each luminaire has a built-in presence detector that dims the light when there is no one in the room.
The change from old to new solution only took two work days.
