A research project conducted by Twente University, the Free University Amsterdam and property consultant CBRE Holland once again confirms the interplay between work surroundings and health, as well as workers' wellbeing and performance capacity.
As part of the research, lighting solutions provider Osram Lighting Solutions installed a 'Human-Centric Lighting' solution for the survey at the headquarters of CBRE in Amsterdam - consisting of a timecontrolled lighting system with a circadian-friendly lighting sequence.
The Healthy Offices survey involved 124 subjects and researchers analysed more than 100,000 data records. The multidisciplinary research project focused on the impact of work surroundings on the potential of employees. Using questionnaires, experiments, biological data, daily movement evaluations and interviews, researchers measured the effects of changes in work surroundings and health over a period of seven months. The team of researchers specified five modifications to the work environment that could theoretically have the greatest impact on health and employee potential; for example, environmental factors such as suitable lighting.
To implement an adequate Human- Centric Lighting solution in the survey, Osram installed a timecontrolled lighting system with a circadian-friendly light sequence, meaning the luminaires adapted their light colour (Tunable White) and intensity during the course of the day. Arktika-P Biolux Tunable White was specified for the primary, widearea general lighting of the office.
The LED luminaire emits direct (4,000K) and indirect (6,500K) white monochrome light. Cool white light is distributed across the ceiling during the course of the day via the separate, controllable direct and indirect components. In the conference rooms, RGBW ceiling-recessed spotlights enable wireless selection of any white or coloured light via a Lightify Pro control for various work and communication tasks.
The participants working in the 'healthy spot', the part of the CBRE office with the new, modern lighting configuration, found their total work performance to be 18% better. Additionally, 71% found they had more energy, 76% thought they were happier and 50% thought they were healthier. The survey results also recorded an accuracy improvement of 12%.
The research project demonstrated that the modification of work surroundings can lead to a better working future for employees. It also represents an intelligent business investment; costs for illness, burnout and employee fluctuation are significant expenses that can be reduced by establishing healthier offices.
