Norway’s first Swan-labeled (Nordic EU Eco-label) school is located in Røyken municipality, just outside Oslo. Sydskogen school, built for just under 400 students and around 40 teachers, has a Passive House Standard, a leading global standard in energy-efficient construction. Further, apart from the ground floor, the building is built entirely in solid wood.
The Nordic Ecolabel criteria cover not only favorable environmental properties for the building itself, but also take into consideration health aspects such as daylight, ventilation and acoustics indoors. The certification also has strict documentation requirements to verify that no components of the building are produced with problematic chemicals.

Environmental strategy for Røyken Municipality and Sydhagen school:
Municipal council decision 2016 • Energy and climate plan 2017-2020 for Royken municipality • Steering group • Process with environmental requirements for the projects in sketch, preliminary project and execution • Collaboration between politicians and REAS • Involvement of the Swan Label
The steering group set environmental goals together with REAS. The environmental goals are based on “Energy and climate plan 2017-2020” Passive house (NS 3701)
- Fossil free construction site
- Greenhouse gas accounting
- Use of solid wood
- Clean dry barley BBBLS
- Greenhouses Reuse demolition
- Water delay on roof
- Greenhouse gas accounts
Greenhouse gas reduction consists of strategy-,design- and construction phase, material selection and energy use in operation. Measures to reduce CO2 are: Material use, fossil-free building site and passive house standard. We use One Click LCA, which makes it possible to load the BIM model and extract material quantities.

Process with the Contractor
The Bergmingrud contractor has used close to 900 prefabricated solid wood elements in the project. With a heavy focus on early phase design, much of the necessary drilling was done at the factory.
Røyken Eiendom wanted the school to be environmentally certified and towards this, they picked the Nordic Swan Ecolabel certification.
“BREEAM is, perhaps, more reputable, but this is not a building we will sell or rent to a private operator; it is a school. Our conclusion then was that the Swan Label was just as good, and we had neither worked with BREEAM nor the Swan label before. As an experience, there were no obvious differences to us,” says Ola Mæhlum in Røyken Eiendom.
Although Project Manager Helge Toft at Bermingrud acknowledges that they might have priced the Swan label risk somewhat higher than they ended up, both the contractor and the builder say that it was okay to build according to the Nordic certification scheme.
“The biggest point for us here has been clarification of all material products, and this has led to the fact that we have had to replace some materials with more expensive alternatives, but it is really good that we are pressed to choose more environmentally-friendly materials. We also had to work hard to find a glass and aluminum supplier that could document a certain degree of recycling, and it was a challenge to find fire-retardants that were also Nordic Eco-labelled,” Toft says.
Apart from the materials, the certification scheme also goes on to dictate some design choices for the project.
“The requirements for light emission means that there is more glass in this building and that the windows have been raised to allow more daylight,” says Toft to Bygg.no.
The architect of the project and the Kebony wood facade (ad)
Kebony was the natural choice for materials when the first Nordic Swan-labeled school was to be built in Røyken. The result is Sydskogen School, a place that is good to be, and good to learn.
The official Nordic Swan brand ranks high. The requirements imposed on the building materials are stricter than the authorities’ own requirements. Therefore, it was important for the contractor behind Sydskogen School to make the right material choices. Kebony uses an environmental technology that offsets endangered tropical woods and traditionally impregnated wood. This is in good harmony with the Nordic Ecolabel’s requirement for the timber to be sustainably produced. Preserving the important forest resources on Earth is about thinking long term, and Kebony is a choice for indoor climate and the environment.
No room for chance
When building a school there are many considerations. You can choose to follow the same track as before, or to reimagine the space. It is this second courageous choice that the Røyken municipality took with contractor Bermingrud AS and the architectural office tegn_3. Kebony was quickly brought to the field as the preferred material in the school’s facades, both for aesthetic and practical reasons.
Colors that inspire
“When we arrived at the course, many of the material choices had already been made, so it was important that we chose a color palette that will compliment these choices and work for many years to come,” says the architect team in tegn_3. Wood paneling on the façade and implementing colorful surfaces gives the building a playful look while blending well into the surrounding terrain and nature-filled backdrop. We integrated universal design into the project, where the use of colors and contrasts emphasizes function and creates variation and connection between rooms. Clear road-finding is a priority, so it is easy to orient yourself in the building.”
The architects in tegn_3 have chosen different colors for the building’s entrance doors to make it easy for students to navigate.
“The colorful details will dress the building as it gets older,” the architects explain. Kebony is a natural material that will change color over time. Today the facades are brown, but eventually the facades will get the gorgeous silver gray patina that characterizes Kebony.
Environmentally-friendly, inside and out
Another measure the contractor has taken to meet the Swan Label’s strict requirements for energy use and operation is to put a solar panel on the roof. Sydskogen school is a so-called ‘passive house’ which means that it has about 25 percent less energy demand than a standard building. The goal has been to build an environmentally-friendly school, inside and out.
“A good indoor climate is especially important in a learning institution, and that’s where Kebony contributes with a breathable and natural façade that is documented as free of harmful chemicals. The school will house approximately 400 students and teachers, and we hope and believe they will find themselves in a building that is on nature’s side,” says the architect.
A building to withstand the test of time
Another important point when building a school is that it can withstand being used for many years. Therefore, compromising on quality is not an option.
“From a purely aesthetic point of view, the Kebony facade will become finer over time, but it is also a weather-resistant material that will withstand the test of time well,” the architects say. Thus, the standard is set for a school that can accommodate multiple generations of schoolchildren – and hopefully will inspire other schoolbuilders to make similar choices.
