Abstract
Brandengen Primary School in Drammen in Norway is a demonstration building within an EU 7FP project, running from 2011 to 2016. The aim of the EU project is to pave the way for future high performance building levels when retrofitting school buildings, i.e. achieving low energy consumption and good indoor climate conditions. Brandengen School's facilities consist of three buildings in bricks, linked together with arcades. The buildings are of historical value and Drammen municipality emphasize to restore the façades to be close to the original historic look.
