Bad indoor climates in schools negatively affect learning. This can be rectified with on-demand ventilation, and schools can save money at the same time.
A research group at Aarhus University in Denmark separated a group of pupils into four classrooms and gave them tests to solve. The air quality in each classroom was different. The results showed that pupils concentrated more if fresher air was added to the classroom. The pupils' performance improved by up to 7% when they had fresher air in comparison with the performance of those in the normal indoor climate. The pupils who worked in the classroom where fresh air was added were able to complete more tasks within ten minutes without increasing their rate of errors.
According to Bent Ole Jonsen, market area manager at the energy department of Caverion Danmark A/S, the results confirm what Caverion has maintained for many years: “The air needs to be replaced. The same applies to offices, because as sure as learning suffers in the classroom, productivity also drops in the workplace when the indoor climate is bad.”
“Companies are increasingly following our advice on changing air quality for the better. I can only hope that the study carried out by Aarhus University will also help municipal politicians to realise that there is a simple way to improve learning results,” says Bent Ole Jonsen.
Good ventilation is much more than just opening windows
“Windows can be opened but during the winter, it is not very nice for people who have to sit next to an open window. Installing ventilation systems is much more effective.
“With the technology available today, we can not only improve learning and productivity – we can also save energy,” says Bent Ole Jonsen.
Letting warm air escape through open windows is like throwing money away. By making the air move through a ventilation system, the heat can be recovered. Moreover, if the building is equipped with on-demand ventilation, the air that is replaced the most is in the rooms that have the most people, making the process even more efficient in terms of money saved.
According to Bent Ole Jonsen, the problem with schools is that many older schools do not have a ventilation system. The schools that do have a ventilation system often find that it does not function optimally. Bent Ole Jonsen believes that better ventilation is an obvious way to improve learning.
“The solution is very simple. If municipal politicians want better schools and improved learning, the indoor climate is an area that should be prioritised. And an on-demand solution will save the municipality money,” says Bent Ole Jonsen.
