November’s Property Technology Live 2018 will explore how ‘human-centric’ lighting at the office of the property company CBRE boosted productivity by 18 per cent.
Additionally, work accuracy improved by 12 per cent, 76 per cent of employees reported feeling happier and half felt healthier.
The findings – by scientists from the Twente University, The Free University Amsterdam – will be seized on by the lighting industry as long-awaited hard evidence that investment in dynamic lighting gives a tangible return.
The time-controlled lighting system features a ‘circadian-friendly’ lighting sequence, which varies the colour temperature and intensity during the course of the day. Employees are stimulated during the morning and early afternoon with high illuminance levels and cool indirect white light. At midday and late afternoon, the light levels fall and become warmer.
The general lighting pendants feature direct light with a colour temperature of 4000K and ulta-cool indirect monochrome light of 6500K. The latter component is distributed across the ceiling during the course of the day via the separately controllable direct and indirect components.
