Oslo's first positive energy school
At Voldsløkka secondary school, both the facade and the roof are covered with solar panels. The panels make up a total of 1,500 square meters.
1,500 square meters of solar panels provide electricity. In fact, enough electricity for the building to produce more energy than it uses.
An energy positive building produces more energy in its lifetime than it uses. The use includes materials, construction, operation and finally demolishing the building.
Buildings account for 40 percent of EU's energy consumption
The European Commission estimates that buildings account for around 40 per cent of EU's energy consumption - mostly for heating and cooling. In other words, there is enormous potential in reducing greenhouse gas emissions in buildings. To achieve the reduction, we need ambitious projects such as Voldsløkka school.
Municipalities in Norway and the EU manage large building masses, and therefore play a key role on the road to climate-neutral societies.
School and cultural center
Energy accounting and solar panels may not be what the future secondary school students are most excited about when they start on the new school. But the students have more than low climate footprints to look forward to in the next three years:
- The secondary school is built for 810 students distributed over grades 8-10.
- The school consists of a new building and the completely renovated Heidenreich building.
- The schoolyard is green with local and open water management and green areas with biological diversity and planting.
- The building also houses a cultural station where Oslo cultural school and Voldsløkka scene are located.
- New bike lanes and sidewalks have been completed on Uelands gate and Tåsenveien, providing a safe school route.
We wish the students at Voldsløkka school a good start at Oslo’s first positive energy school!
