The Ruselokka Skole in Oslo is a school for all ages ranging from elementary to junior high . In 2017 , after extensive discussion , the decision was taken to demolish the old school building and build a new school in the same spot . The new school was planned in line with high environmental standards and was completed in 2021 as a nearly zero-energy building . A model project from FutureBuilt
The modern school building has seven floors and a total surface area of around 110,860 square feet . It provides space for a school population of almost 1,000 students from first to tenth grade . One special aspect of the school is its collaboration with the Norwegian Opera in Oslo . A large dance hall and special music and practice rooms were included in the new building for the school ’ s national ballet and dance division . A green roof terrace creates additional

outdoor space for the innercity school building .
The school is a model project from FutureBuilt , a Norwegian platform for urban climate innovation aimed equally at developers , architects , municipalities , contractors and building users . The aim is to produce 100 model projects that meet the sustainable development goals of the UN and the Paris Climate Conference and reduce CO 2 emissions by at least 50 percent . Sixty-nine model projects have already been implemented since 2010 .
The materials cycle and carbon footprint
Innovative strategies were used to build the Ruselokka Skole in order to fulfill the initiative ’ s stringent requirements . One focal point was the circular reuse of materials and building components from the old school building to boost the local value chain , save gray energy , reduce waste and keep CO 2 emissions to a minimum . Another focal point
|
was construction as a nearly zero-energy building ( nZEB ) to the Passivhaus standard . A third aspect of the ambitious strategy was high quality standards for a healthy indoor climate , a lighting concept based on daylight , and high standards for acoustics and noise protection . During the construction process , operations on the building site were free from emissions and fossil fuels .
Before demolition , 4,500 reusable bricks , wooden beams and granite blocks from the old school were saved , mapped and stored temporarily . These were intended for reuse in the new school wherever possible . Unfortunately , for structural reasons , the old bricks from the school could not be used to build the new brick facade , so they were used on two interior walls instead . You can now find the granite from the old stairs being used as outdoor seating . Many of the building components and materials that were stored were also used in other construction projects .
The reinforced concrete structure of the building used a special low-carbon concrete . The CEM III / B blast furnace cement used for concrete production reduced CO 2 emissions per cubic meter of concrete by up to 25 percent . The concrete takes longer to harden , but this wasn ’ t a problem on a summer building site . Reinforcements were made from recycled steel .

Energy production and smart solar protection
Solar cells on the facade and other solar modules on the green roof help produce energy . Each year , the building operators expect the solar energy system measuring over 7,500 square feet to yield 75,000 kilowatt hours of energy . This is intended to contribute to the school ’ s power supply .
Dynamic solar protection glazing from SageGlass , a Saint-Gobain company , also helped achieve interior comfort . The adjustable glass adapts to weather conditions and regulates light and heat in the building automatically . The transparency of the glass and the unimpeded view of the outdoors are always preserved , offering teachers and students alike a high level of visual and thermal comfort . Merete Hansen , Principal of the Ruselokka Skole , is impressed by this innovation in glazing . “ I ’ ve got a large corner office with a view of the schoolyard , looking out toward the city . Thanks to SageGlass , I can always keep track of who ’ s coming to school and what the kids get up to on their break . Although the electrochromic glass darkens on sunny days , the view is always unimpeded , and I can still see what ’ s going on . I ’ m delighted with the sense of transparency and the possibility to screen myself without the outside world seeing me ‘ draw the curtains .’ I would warmly recommend this innovative technology to other school buildings .”
