Aalborg University

Base LED acclaimed for energy savings

< Back
 
Like all universities, Aalborg is concerned with cutting energy use as far as possible without reducing the quality of its facilities. Indeed Danish building regulations (Bygningsreglementet) require a reduction in consumption of 10 and 20% from 2006 levels by 2011 and 2013 respectively. Keld Bo Jensen, electrical installation manager, heard about the potential electricity savings he could achieve using the Base LED downlight along corridors in place of the existing 13W compact fluorescent installation, and invited Thorn lighting consultant Bo Janniche to demonstrate just how much energy could be saved. He was surprised at the result!

“The interesting thing about the transition to Base LED, in addition to the 30 per cent savings, is a more than doubling of the illuminance (70 to 180 lux) with a better light distribution. In addition, the LED light source has a significantly longer life expectancy which extends time-frames for renewal and maintenance, thus contributing to the economies,“ he said.

To date over 100 downlights have been installed. Other Thorn luminaires, such as Planor MPT and Track (Equaline), are used  in the classrooms and lecture theatres helping the university to reduce overall lighting energy requirements by 20 per cent, while still improving levels of comfort.

Rated at 12W, the Base LED downlight matches the light levels of an 18W compact fluorescent downlight, yet uses 50 per cent less energy and lasts over four times longer. Available in 2700K and 3500K options, it has an excellent CRI (Ra) of 94 and is dimmable to 20 per cent.
