BLOX

OMA, the studio of the Dutch architect Rem Koolhaas, designed the Blox. 27,000 square metres on five storeys above and below ground. The white and green frosted glass facade is non-transparent to the outside and forms interlocking geometries. An abundance of glass – in stark contrast to the surrounding historical old town district of Copenhagen with red clinker facades that are typical to Denmark.

The building is a mixture of architecture and design centre, workplaces in a network for urban renewal, rented apartments, children's playground, fitness studio, restaurants and fully automated underground car park. This is a building which is designed to reflect every aspect of urban living, explained the press officer of the DAC.

The motivation of the Realdania foundation, Denmarks biggest private investor and sponsor of the Blox "We want to breathe life into what up till now has been a lifeless place" has transformed the harbour from a deserted ship mooring point to an inner city experience.

The building was built over Copenhagen's busiest arterial road. Increased sound insulation was therefore one of the special requirements for the glazing and the window. Gretsch-Unitas developed parallel-projecting hardware for the windows measuring 2110 x 4280 mm and weighing 750 kg. These are special fittings for parallel opening windows with six Y scissors. The windows are opened by motor via chain drives and two locks (up to 600 N) with a stroke of 120 mm. A free cross-section of 65 mm is achieved. The hardware components are connected to the sash and frame profile by means of a back lining adapted to the weight. The drives are supplied with a specially developed special control system and are operated by dead man's switches. The special control with relay and power supply unit is designed in such a way that the fabricator could easily carry out the wiring of all components independently.
The continuous function test was carried out on site (in the workshop) at the customer's premises, with Gretsch-Unitas providing all the test equipment and accompanying and monitoring the test. In order to obtain the system test, the locking devices were contributed by the system supplier.

Everything from one source: As a specialist for all types of opening in the facade, Gretsch-Unitas combines object-related special parts - which are developed as innovative engineering services according to individual customer specifications - with elements from the proven standard range. GU supports customers from the technical planning and design, through testing, to the implementation of projects all over the world.
