The Düsseldorf city gate is one of the architectural landmarks of the Nordrhein-Westphalian capital. The building rises like a portal above the Rhine bank tunnel and forms the entrance to the city centre. The International law firm McDermott Will & Emery is based right where the top three floors connect the two pillars.

The legal experts there represent companies across the globe. Working across time zones often results in unconventional working hours and that’s where lighting comes into play, making a significant contribution to a productive, comfortable working atmosphere. When creating their new office space, the firm focused especially on state-of-the-art lighting solutions with a completely new lighting concept. Technical expertise and flexibility were needed, since the modernisation works in the existing building required agile solutions. “In Regent Lighting, we found the right partner for our ambitious project”, says Daniel Fahrion, Office Manager at McDermott Will & Emery. “We were highly impressed by the collaborative cooperation and their competent handling of a structural situation that was initially complex”.

Straight lines and a clearly structured interior design concept with carefully selected materials characterise the project. The lawyers' precise way of working is also reflected in the choice and installation of lighting. The streamlined and yet aesthetically pleasing Item pendant luminaire creates homogeneous illumination in offices and meeting rooms alike. As a tailor-made solution, Regent Lighting developed a Tunable White version of Item for this project. Tunable White enables the colour temperature to be adjusted to align with daylight conditions. This has a positive impact on people’s well-being (Human Centric Lighting).

But as working hours at the firm do not always correspond with the course of daylight, the colour temperature of the luminaires can also be individually adjusted from 2,700 K to 5,700 K and their brightness can be adapted too. Employees in individual offices can even adjust the lighting in the room in accordance with their personal needs. This has a positive impact on their performance, concentration and well-being. And with this technology, the rooms without windows and daylight can now achieve the same luminous efficacy as those with daylight.

In the library, cafeteria and lobby areas, the elegant, Solo Slim luminaire creates soft contrasts compared to the strictly arranged Item light lines. The round ceiling-mounted luminaire marks rest zones, breaking up the concentrated atmosphere in the working areas with its interplay of shapes. And in the surrounding areas and corridors, the direct-beam Purelite D ensures uniform, enjoyable illumination. A sensor controls the lighting and dims the luminaire to 40% after a set period of time before it goes out - energy efficiency played a crucial role for McDermott in awarding the contract.

“The new lighting concept is a game changer”, says Daniel Fahrion. “The high-end luminaires with daylight function, the sustainability and the overall outcome far exceeded our expectations”.

Optimum lighting at all times of the day, clear aesthetics reduced to the essentials and a harmonious overall concept are the result.
