Philips Lighting has helped to transform the Czech Republic headquarters of energy company innogy by installing an LED lighting system tuned to support the circadian rhythms of innogy’s office staff, including stimulating their energy levels at set times in the day. Employees enjoy a comfortable bright light – similar to natural daylight – to start their day and after lunch. This helps to stimulate energy levels and enhance workplace comfort and vision, supporting a sense of wellbeing and performance. The stimulus from the ‘human centric lighting’ fixtures is likened to a strong cup of coffee.
In November 2017, innogy completed a renovation of 10 000 m2 of office space at its Czech Republic headquarters in Prague. The company went from a traditional closed office environment to open plan, and used the opportunity to create a work environment that enhances the comfort, wellbeing and productivity of its 550 office employees. Lighting played a key part of the renovation which involved a new restaurant, furniture, healthy food, kitchens and creativity spaces.
Philips Lighting installed a networked lighting system consisting of approximately 2000 Philips LED luminaires. These include 860 Philips PowerBalance tunable white ceiling fixtures and 96 Philips LuxSpace tunable white downlights, programmed to provide different light settings at various times of the day. The subtle differences in the colour temperature and intensity of the lighting also support eye comfort and may be personalised by employees to suit specific tasks. While the emphasis of the lighting system is on enhancing employee comfort, it is also helping to improve operational efficiency through remote monitoring and maintenance.
“We wanted to create an outstanding environment for our employees. At the beginning of the day, office lights mimic natural daylight, providing a useful energy boost. The light levels decrease until after lunch when we give another boost to help staff over the post-lunch energy dip. Nearly 80% of employees surveyed described the new lighting as better or much better than the previous fluorescent tube lighting, while 60% agreed that it contributed to a place in which they wanted to work,” said Tomáš Michna, senior manager for facility and services at innogy Czech Republic.
The installation includes approximately 150 sensors that detect human presence and switch the lights off in a room or area when it is vacated. The combination of energy-efficient LED lighting and controls has enabled innogy to reduce electricity used for lighting by around 50% compared to its previous fluorescent lighting.
