THE HUMAN-CENTRIC lighting at a Norwegian bank delivers an ultra-cool 800-lux ‘focus’ boost to employees every day.
The SpareBank 1 Nord-Norge branch office – just 50 miles (80 kilometres) south of the Arctic Circle – is one of the first banks in Europe to install so-called human-centric lighting. It’s hoped that the dynamic lighting will reduce ‘Polar night depression’ for daylight-starved residents of extreme northern regions.
The lighting mimics daylight by changing intensity and colour temperature throughout the day to improve concentration, prevent sleeping disorders by helping to set occupants’ sleep-wake cycles and provide an enhanced sense of wellbeing.
‘Between five and 10 per cent of the population struggles with Polar night depression,’ the bank’s technical boss Øystein Eikrem told Lux. ‘This leads to dejected humour, low level of energy, diminished motivation and constant fatigue. These annoyances can be reduced with the right lighting, and therefore human-centric lighting is even more important for us who live in a country with a long winter.’
The lighting system in the team rooms for the 36 employees are preset according to a fixed day cycle. In the morning when the staff arrive at work, the lighting is warm white.
After a while the lighting shifts to cold white and lighting intensity is increased to 800 lux, before it is lowered again, and turning warmer towards lunchtime. After lunch the blue-white tones increase again, before they decline towards the end of the day, and the warm white light becomes more prominent.
In the meeting and quiet rooms it is possible to adjust the light in three categories – normal lighting (4000 kelvin, 500 lux), calm lighting (3000 kelvin, 500 lux) and focus lighting (6000 kelvin, 800 lux), as required.
‘Several research reports, including from the Netherlands and Norway, reveal positive results from use of human-centric lighting in office environments and schools respectively. This is new and – to say the least - exciting. If human-centric lighting can result in enhanced wellbeing, and a decline in sick leave, then it's a win-win situation for everyone,’ says Eikrem.
'Our most important resources are the people who work in the bank. Then we must organise it so that they have the best conditions. Not just inviting, pleasant work environments, but we must also implement the best technological arrangements for them that includes future oriented lighting. It also promotes a more enjoyable experience for those visiting the bank.
‘We are waiting in anticipation to see how much job satisfaction improves and how much sick leave declines, as we believe it will’.
The luminaires and light management system are supplied by human-centric lighting pioneer Glamox. ‘This is the first time we have installed human-centric in a bank, and this will be rolled out in many of the bank's locations,’ said Glamox sales engineer Espen Ytterstad.
‘So it’s a pilot project for us and the bank. The bank is daring to invest in creating the ultimate in a working environment, and that their people really enjoy their job.’
‘We've only just moved in, and can see we have plenty of light and good lighting,’ said bank branch manager Tor Magne Aanonli. ‘Even though It is still light outside, we can't wait to see what it will be like when the days start to darken’.
