The indoor climate impacts more than we think
Along with the health aspects, it is also important that the indoor environment promotes productivity and performace.
We are generally very keen to obtain tools to be as effective as possible in our daily lives, for example creating good conditions for learning in our schools through competent teachers and good teaching materials.
Unfortunately, the indoor climate is often forgotten in these discussions, despite the fact that there are many factors that have a great impact on our performance and productivity.

Increased ventilation improves results
This graph represents results from a study done on students - it shows that by moving from 'open-window' ventilation to a balanced mechanical ventilation, basic reaction time, basic memory and word recognition has a marked improvement.
Children spend a considerable amount of their time in crowded classrooms and most teachers are aware of how sound levels affect children’s learning abilities and therefore put a lot of effort in to keep noise done. However, teachers may not be aware of the impact of factors such as temperature and air quality, and often have no possibility to measure them.
When the carbon dioxide in a classroom is too high, pupils become restless and disruptive. They lose their concentration and their learning ability decreases significantly. When the ventilation rate is doubled, research shows that the students' performance can rise by around 15%.
Moreover, cognitive testing of students shows a 5% decrease in attention in poorly ventilated classrooms. The researchers equate this to the effect of a student skipping breakfast.
