Ventilation in the classroom

Little progress with ventilation in the classroom'.

In the area of ventilation in the classroom, little has actually changed in the past year, experts complain. Professor of Building Services Innovation Atze Boerstra of Delft University of Technology: "The Ministry of Health, Welfare and Sport has now issued a guideline on ventilation. I could have done that last year. We are really losing time.

Earlier this year Boerstra was one of the 20 scientists who sent a letter to outgoing prime minister Rutte to emphasise the importance of ventilation in press conferences. With results, but it is not enough yet, Boerstra and his colleague Professor Philomena Bluyssen tell RTL Nieuws.

Good ventilation

"Good ventilation remains essential in the fight against the coronavirus. We are not giving up yet," says Bluyssen.

Many school boards have now purchased CO2 meters on their own initiative. A CO2 value that is too high is a signal that a classroom needs to be ventilated.

Next challenge

This is now the next challenge, because in many schools the ventilation is not in order. Last year, 38 percent of schools said they did not meet the ventilation standards set out in the Buildings Decree. And last winter has shown that opening windows during a cold spell is not a workable option.

The SUViS scheme, of which the second pot of 100 million will become available in October, offers some solace in investing in a better indoor climate. The problem is that only 30 percent of the renovation costs are covered and many municipalities are not prepared to co-invest.

Really setting the pace

Atze Boerstra is pleased that 'ventilation' has been added as the fourth basic measure. "But it is now time to give it hands and feet. We really need to speed things up now", he told RTL News.
