Project // CCH Hamburg
Place: Hamburg, DE
Architect: agn Leusmann GmbH & TIM HUPE Architekten
Completion: April 2022
The daylight planning
The large window frontage provides a direct link to the outside world and its surroundings. In addition, during the day there is enough light in the corridors and the entrance area so that no artificial light has to be switched on. Thus, the planned artificial light sources are only gradually switched on in the evening during the twilight hours. This concept saves energy.
The windows were fitted with solar control glazing. The roller blinds attached from the outside provide sun protection on strong sunny days in summer.
The artificial lighting design
The challenge in this project was to stage each hall differently and to equip and coordinate them with two light colours according to their functionality. In addition, each room can be individually controlled with different pre-programmed and free lighting scenes. Each hall is identified by a letter or number outside in the foyer. The halls are suitable for lectures, concerts or similar events and are equipped accordingly.
Forecourt & Foyer
The CCH building can be reached directly from Hamburg's main railway station. Lighting systems are embedded in the concrete façade and ensure good visibility at dusk, but also create an atmospheric mood that is reflected inside the building.
In the entrance area of the CCH building, an incredibly modern chandelier takes centre stage. This has a span of 6m in diameter and weighs 1.2 tonnes.
In order to put the chandelier in the limelight, down lights were installed in the ceiling. In addition to the chandelier, these also illuminate individual zones of the foyer.
A wood-clad wall with nested slats extends up to the first floor. Behind these slats, light strips were installed to create an atmospheric mood.
Hall 3 has special cylinder lights that hang from the ceiling in the shape of jugs. There are a total of 1500 of them decorating the ceiling of the room. These lights were to be preserved. So the challenge here was to dismantle every single lamp and install two fluorescent LED tubes against the previous halogen lights in the colours white/blue and red. In addition, each individual luminaire had to be marked so that it could be re-installed in the correct position.
The walls are illuminated by the downlights in the ceiling. These were additionally installed to ensure atmospheric ambient lighting. As this room is used a lot for presentations and smaller events due to the arrangement of the table groups and the adjacent stage, various lighting scenes were pre-installed here, which can also be individually controlled in terms of brightness.
Nested ceiling, pyramid-shaped structure, this is the best way to describe Hall 4. At the bottom of the ceiling, a light line extends to the front of the stage. The basic lighting is replaced by downlights tilted towards the stage. In addition, stage spotlights have been installed for larger extravagant events.
Hall 1 extends over the second and third floors. The brick-look side walls were to remain. The ceiling was interlocked to create better acoustics. The basic lighting in the entire room, including the stage, has two light colours. In addition, an LED light strip was installed in the circumferential joint of the room. Likewise in the steps. The light from the strip can be dimmed for the performances.
A dark blue surface decorates this room. Carpet is found not only on the floor, but also on the walls and ceiling. This makes for better acoustics. Ventilation as well as lighting are located between the ducts of the shed-like ceiling.
