Lighting at flagship office uses 3W per square metre

A Norman Foster-designed office in Budapest has set a new standard for large premium workplaces with an installed lighting load of just 3W per square metre.
The 27-storey building for the oil and gas company MOL Group uses linear LED lighting to deliver a general illumination of 300 lx. Occupants who require more are encouraged to use additional task lighting.
In a scheme designed by the leading German lighting design firm Licht Künst Licht, linear LED luminaires in three different lengths are mounted to a support rail flush with the ceiling and visually recede in the glare-free ‘light chambers’.
They have two different light distributions – 48 or 72 degree beam angles –  allowing the designers to respond to the respective room geometries and requirements.
The illumination of the approximately 25-metre-tall atrium is provided from lateral openings in the front sides of the gallery floor ceilings, which accommodate clusters of up to four adjustable track-mounted spotlights with a colour temperature of 3000K and 4000K.
The directional light with beam angles adapted to the respective ceiling heights impressively illuminates the floor with powerful brightness and invitingly gives the room attractive warm white light through the reflection of the surface. The spotlights with 4000K light colour additionally accentuate the trees and plants positioned in the spacious and light-flooded atrium.
The building houses a food court and cafés, a gym with spa area, and a conference center as well as providing numerous other facilities for employees on the lower floors.
The upper floors, up to the 27th story, feature flexible-use workspaces connected by the recurring element of a lush indoor greenery. A magnificent view of the city is offered by the Sky Deck at lofty heights, which is also open to the public.
With a total area of 86,000 square metres, a state-of-the-art campus flooded with daylight has been created in collaboration with the local architecture studio Finta and the team from Kinzo Berlin, serving as a social catalyst and offering an attractive space for collaboration, creativity, relaxation and inspiration for up to 2,500 employees.
The building achieves LEED Platinum and BREEAM Excellent ratings.

• Remanufacturing Lighting is the subject of a special one-day conference organised by Recolight and taking place on Thursday 27 April 2023 at the Coin Street Conference Centre in London. This CPD-approved event will give you the tools, insights and contacts make a success of luminaire reconditioning and reuse. You’ll learn how to sell the concept of reconditioned lights, develop best practice policies, comply with the standards, set up a testing regime for reused luminaires and remanufacture fittings at scale. The gathering will also give you inspiration from real world projects which prove that remanufacturing can be a success everyone. You’ll also meet key players in the remanufacturing industry  network with specifiers with the power to get your products into projects. See more HERE.
