Leading consulting group with a 360° approach
Nordea Bank's new headquarters in Ørestad, close to the city of Copenhagen, is an ambitious sustainable building, aiming at the highest LEED standard - LEED Platinum.
In 2017, Nordea Bank moved from Christianshavn in Copenhagen to an attractive location in Ørestad Nord next to DR (Danish Broadcasting Corporation) and the DR concert hall, Koncerthuset.
The new building features 46,000 square meters of sustainable floor area in six floors, of which 5,000 square metres are occupied by one of Northern Europe's largest trading floors and data centres.
From the beginning, the bar was set high for the new building, both in terms of architecture and sustainability. Only with a complete focus on the sustainable aspects of the construction process, will it be possible for the building to achieve the high LEED Platinum certification, which is reserved for the most energy-efficient and environmentally friendly buildings.
With regard to the data centre, the energy consumption is calculated according to a particular model in the LEED system and measured against a different benchmark than the rest of the building. In this way, it is possible to achieve platinum in the LEED certification, although the building has an energy-consuming data centre.
COWI was consultant for the LEED certification. Along with Henning Larsen Architects, we implemented a number of sustainable initiatives including low energy consumption, a healthy indoor environment including the use of healthy materials, and rainwater management:
Before the building was handed over in 2017, it underwentextensive commissioning. This involved testing all the technical facilities including ventilation, pumps and lighting to ensure that the complex systems can work together.
At the same time, the filters in the ventilation system were replaced, and the whole building was flushed with fresh air before it was put to use.
In the LEED system the office building will be classified as an ordinary office building. The LEED system has a special module for data centres, which are certified according to other criteria than the rest of the building. In this way, it is possible to obtain LEED certification of platinum, although the building has an energy-intensive data centre.
LEED stands for Leadership in Energy and Environmental Design, and is the US system, which is operated by the US Green Council. LEED operates with four categories: Certified, Silver, Gold and Platinum.

Calculations for the solar cells show an energy consumption of 38.7 kWh/m2 a year, when a solar cell area of 1,870 m2 is implemented. This means that the energy consumption of the building will be approx. 6% below the required low-energy class in 2015, which is 41.0 kWh/m2 a year.
