Fornebu S

Winner BREEAM Awards 2015

Building of Year Norway 2014

Winner BREEAM Awards - Retail New Construction2015

Fornebu S is the first shopping centre in the world to receive BREEAM Outstanding certification (score: 89.5 %).
The shopping centre, offices and other commercial areas are built in addition to “passive house” standards while the housing is built according to TEK 10 building code guidelines. Placed centrally in Fornebulandet the buildings are integrated to the Oslo public transport system including the planned extended tram system. This focus on public transport as an integral part of the environmental strategy of the scheme alongside access to electric car recharge stations and extensive bicycle parking.
Timber cladding was selected for its low carbon footprint, renewability and the short distance from production to site. It also reflects the green context surrounding Fornebulandet and provides a visual challenge to traditional materials and expectations used in the shopping centre typology. The ambition of Fornebu S is to be a pioneer in the field of sustainable development and a role model for future environmentally responsible shopping precincts.

GREEN ROOFS & BIODIVERSITY - Fornebulandet and its environs are now again host to a diverse array of flora and fauna, some species of which are under threat. The roof garden at Fornebu S contrib- utes positively to this biodiversity with the conscious use of native plant life.
The new Fornebu land is formed with landscape corridors from shore to shore. The green roof over the shopping center is not only beautiful to look at for those living in the roof top apartments it also serves to strengthen these green corridors in the landscape The green roof reduces the impact on the local wildlife by creating a high level corridor through the development. The roof is planted with plants of the habitat that were natural to Fornebu before the airport was built in the 1940s, Many of the plant types are rare to Norway particularly “ kalktørreng “ dry chalk meadow yellow and pink stone-crop species.
The planting is in many ways become a metaphor for the design/building process. During concept development in 2012/13 seeds from local grass and flowering plants were collected on the peninsula and surrounding islands in Oslo Fjord. The seeds were propagated ready for planting in spring 2014 now there is created a sustainable landscape with over 84 different plant species. A future environment for a diversity of plants and a multitude of insects and small birds! A green rooftop parallel to Fornebu S below.

ENERGY - The calculated amount of energy consumed in the building is 85.9 kWh/m2 (according to NS 3701), which is about a 60% reduction against the regulatory level. There is little energy requirement for heating. Walls, roofs and windows have increased insulation standards. Air leakage is also minimised through close control of detailing and construction.
LED lighting is used extensively. LED lights use little energy and they emit little heat so as to reduce the energy demand for cooling which is a major energy load in shopping centres and other public buildings even in Norway. The green rental agreement has been critical to reducing tenants cooling demands .Energy for heating and cooling comes from district heating/cooling plants that obtain energy from the Oslo Fjord, The cooling systems in the supermarket are integrated with the heating /cooling systems to maximise energy re-use and minimise energy use. On the roof we have one of the largest solar parks covering an area of approximately 1600 m2. Maximum solar energy combines with maximum cooling requirements.

Other important features associated with the building’s energy performance are:
- 1043 m2 solar cells producing 140 000 kWh/year
- energy efficient and water preserving sanitary equipment
- comprehensive metering and an energy monitoring system to help optimise energy and water use.

MATERIALS - Low carbon Concrete means that a large part of cement content is replaced by fly ash. Production of cement is a high energy process resulting in CO2 emissions. By using low carbon concrete emissions are reduced and waste products are put to use. Virtually all the concrete used in Fornebu S is low carbon. Timber locks in CO2 naturally and processing wooden materials used in construction requires relatively little energy. Timber is also one of the few easily accessible building materials that Norway has in abundance.

FACILITIES - Employees and visitors are encouraged to cycle and use public transport to and from Fornebu S. There is secure bicycle parking, good wardrobe facilities and real-time displays with information about buses departures. Buses and the future tram system stop right outside the main entrance.

INFORMATION - From two information banks “Environment Columns “ placed in the central atrium one can read about the environmental qualities of the centre and follow energy use and production. An Environmental Trail game asks the user various energy and environmental issues related to the centre . You play the Environmental l trail using a smartphone.The game requires in addition to some previous knowledge also active use of the information on the Environmental Columns.
For the very young there is Environment Quest, a game in print. In addition the centre has prepared various “school packs” including various external links for use by local schools and kindergardens.
