Résumé

Two very recently completed research projects at DTU (Technical University of Denmark) make it clear that designing classrooms to maintain CO2 levels below 1000 ppm is failing to provide good working conditions. As a consequence, tens of thousands of children in Scandinavia alone, and millions more worldwide, are finding it much more difficult than need be to perform schoolwork during the 10 years that they spend at school. The new findings demonstrate that the problem is almost universal, that the negative effects reducechildren's performance of schoolwork much more than is currently assumed (by 20-30%), and that providing windows that can be opened is not an adequate solution - teachers do not perceive that the air quality is poor, so they cannot and do not open windows when they should. Routinely leaving windows open would often cause thermal discomfort and almost always waste large amounts of energy. Good engineering could make schoolwork seem much easier while reducing energy use in schools.
