The Crystal, the new extension to the financial institution Nykredit is sited northwest of the existing headquarters, called the Glass Cube, on the edge of the new waterfront and the historic Copenhagen.

In terms of both form and scale, the building is intermediate between the city and the harbour, and harmonises with neighbouring buildings. On the southern side, it rises with reference to the gable apex of the “Elephant House” and creates space for the main entrance. From the corner of Puggardsgade and Hambrosgade, the passage under the building allows a clear view towards Nykredit’s head office building and the harbour.

The interior of the building complies with the demands for functionality, flexibility and efficiency. The typical floor plan is disposed in a Z-shape around two atria, ensuring that all workstations are well lit and enjoy a view. The disposition of the plan allows the accommodation of an open plan, separate offices or meeting rooms. The large three-dimensional steel structure constituting the building’s constructive system functions as an architectural element while at the same time freeing the building of columns, creating maximum flexibility in the office spaces.

The double-glazed façade has integrated solar screens and is decorated by a subtle silk screen frit design that mitigates solar ingress, reflects daylight, and gives the building a homogenous expression which enhances its sculptural form.

Sustainability:
Energy: The design team has brought a holistic approach to the environmental strategy underlying the project. The scheme manages to combine a completely transparent office building with an exceptionally low energy-consumption at 70 kWh per square metre, which means that the building consumes 25 per cent less energy than the requirements of the existing energy legislation. The roof is covered with highly efficient photovoltaic panels generating 80, 000 kWh per year. In addition, the triple-layered inner glass façade provides extremely effective thermal insulation, with a U-value of only 0. 7 Wh per square metre.

Water: Rainwater run-off is collected and used as grey water for toilet facilities throughout the building, while sea water provides additional cooling for the building.

Ventilation: The scheme operates a night-time cooling strategy where natural ventilation is introduced through the double façade and extracted through the atrium skylights, maintaining optimum internal temperatures.

Context: The building floats above the plaza resting only on a single point and a single line, and it is carefully harmonised with the neighbouring buildings. The additional public space at ground level creates a dynamic public realm.

Daylight: The highly transparent building with a subtle silk-printed design on the outer glass façade functioning as a sunscreen creates a harmonious and versatile working environment for all employees.
