  • Human-centric Office Lighting ‘Improves Productivity’

    A survey showed that 'human-centric' lighting at the office of the property company CBRE has boosted productivity by 18 per cent.

     

    THE INSTALLATION of 'human-centric' lighting at the office of the property company CBRE has boosted productivity by 18 per cent, results of an experiment show.

     

    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.

     

    Additionally, light sources were aligned onto the walls to create high vertical illuminance levels. Luminaires suspended from the ceiling in the open office area generate a pleasant indirect light component and avoid glare. In total, the luminous intensity was almost doubled.

     

    The Arktika-P Biolux tunable white system from Osram was used for the general lighting of the office.

    Tunable white lighting in the classroom: The new ROI is ROO

    Throughout the past few years, we at LEDs Magazine have seen more solid-state lighting (SSL) product development targeted at educational environments. School officials, especially in the public-school arena, must manage strict budgets and plan strategically to obtain the best return on investment (ROI) possible, so the potential financial implications are important factors — first, the cost of premium equipment and installation, but then balanced against the possible payback due to energy efficiency initiatives and less maintenance. One consideration beyond the established cost reductions of SSL in institutional buildings such as schools is the possible impact of tunable white lighting in the classroom. Naturally, dimmability and other controls features such as granularity of color temperature can be customized to various classroom tasks and increase visual acuity. But what’s becoming even more appealing to educational administrators is the ability to influence less “visible” factors in the classroom, such as mood, behavior, and concentration. Strategies in Light, co-located with The LED Show and Lightspace California, will draw more attention to so-called human-centric lighting applications as this, also known as lighting for health and wellbeing. One such presentation, “Lighting for pupils…Tunable white lighting in the classroom and the new ROI,” by Tricia Foster of Acuity Brands Lighting and Catherine Hollenshead of Estes, McClure & Associates (EMA), will feature a case study on a Texas school district’s first-hand experience using tunable white lighting in several classrooms. Here the speakers give a glimpse into the new classroom experience. They will offer up additional details during SIL on how ROI has evolved into “return on objective” (ROO) in such installations. — Carrie Meadows
