Norway’s most environmentally friendly school?

The new Horten Upper Secondary School was ready to welcome 1,200 pupils in autumn 2019. It is the first school building to be built to the energy-plus standard in Norway.

The new Horten Upper Secondary School is a national pioneer project in the area of the climate, energy and the environment. The school was ready to welcome 1,200 pupils and 200 staff in autumn 2019. In order for it to be an energy-plus building, a range of measures were implemented during the building’s construction to reduce its greenhouse gas emissions. The building has solar panels on its roof that produce 500,000 kWh per year and this, together with deep geothermal wells with thermal storage, helps to ensure that this autumn the school’s pupils will start at Norway’s first energy-plus school.

A range of well thought-through and extensive measures to address the impact of the building on the climate were planned. The school has largely been built out of sustainable materials such as massive timber, low-carbon concrete and recycled steel. This helped ensure that the building would produce 40% less CO2 emissions than a standard reference building. During the construction process itself, the Municipality had an ambition of making the construction site fossil-fuel free, and high-quality arrangements have been made in terms of walking, cycling and public transport services.

KBN commends Vestfold County Municipality on its construction of the new Horten Upper Secondary School – it is a good example of innovation and environmental ambition!
