Law firm installs circadian lighting

In the private offices, occupants can adjust both intensity and colour temperature of the Litecontrol luminaires with integrated SpectraSync technology based on need or preference.

LAWYERS in a global law firm now have the ability to tune the colour temperature of their lighting to suit their work patterns and activities.

‘Adjusting office lighting to simulate changes in outdoor sunlight levels, based on the time of day, can enhance employee productivity,’ said managing partner Kevin Barner.

When Michael Best recently moved its head office, LED lighting controlled by colour temperature tuning capabilities was at the top of the company’s wish list.

Michael Best is a full-service global law firm with more than 250 lawyers and 13 different office locations. The firm serves international corporations, as well as municipalities, trade associations and individuals.

The firm decided to consolidate operations at a new head office in Washington D.C.

The 3,000 square metre Class A office space features impressive natural light and ten-foot floor-to-ceiling windows.

After evaluating LED lighting Michael Best selected Hubbell Lighting as the luminaire and controls supplier.

Hubbell developed a tuneable system that would meet the needs of varying light colour and quality to provide employees ideal light while also meeting LEED requirements for energy efficiency.

Even with an open office layout with many large windows and significant daylighting options, there would still be areas where employees don’t receive enough daylight due to factors such as season, cloud cover, desk orientation and window shade position.

Research shows that occupants see real value in being able to control the lighting temperature in their spaces. By strategically integrating this technology into its design, the firm understood it would then be able to add to its already impressive list of perks for current and prospective employees.

These areas were targeted to benefit substantially with the SpectraSync system.

In the private offices, occupants can adjust both intensity and colour temperature of the Litecontrol luminaires with integrated SpectraSync technology based on need or preference.

The four presets can be customised in the field or used with default programming. One advantage of the presets – it provides the occupant with the proper colour and intensity of light rather than an average light level or high CCT, without compromise to vertical illuminance.

Michael Best elected to use the following presets:

  • ‘Focus’ – 5000K
  • ‘Work’ – 4200K
  • ‘Normal’ – 3500K
  • ‘Calm’ – 2700K

Additionally, the NX Specialty Switch Station provides employees with the ability to raise and lower the brightness of the lighting, as well as turn the lights on and off in a room or designated zone.

This can be used in conjunction with the colour tuning wall station and operates independently from the colour control.

This offers employees another level of dimming control they can select based on their mood, the requirements of work to be done in the space and daylighting conditions.

Kevin Barner, managing partner of the Washington D.C. office for Michael Best, can set meeting spaces to cool lighting during business and warm lighting during a special social event.

Employees have the ability to adjust the SpectraSync-enabled luminaires in their offices, workspaces and conference rooms with the touch of a button.

Employees can also adjust the lighting to meet their personal preferences, enhance visibility, materials and colours or the aesthetics of the space.

Because the SpectraSync system runs on the NX Distributed Intelligence backbone, there’s opportunity for Michael Best to tweak the system and make updates as needed.

Through its work with technology companies, Michael Best is aware that light does have an impact on people.

Ongoing research is being facilitated to understand how light can affect human sleep cycles, health and productivity.

For example, the integral NX sensors allow Michael Best to automatically adjust brightness levels to account for incoming natural light. Vacancy sensors are already being used to override control of all fixtures, enhancing the project’s efficiency.   

‘Adjusting office lighting to simulate changes in outdoor sunlight levels, based on the time of day, can enhance employee productivity,’ said managing partner Kevin Barner.

‘Happier employees are more productive and more likely to stay with us. Bottom line: this technology helps make people more comfortable, based on their personal preferences.’
