Intermittent ventilation, cross ventilation, tilted windows? How to ventilate properly.


Most people had never heard of them before the pandemic: aerosols. These tiny suspended particles fly through the air and, according to corona research, play a far greater role in the infection with Covid-19 than initially assumed. Like pollen that is blown up by the wind, aerosols also spread in the room, condense and can thus pass the virus on to humans via the air. This is one of the reasons why a method of preventive control has become en vogue these days, which, unlike aerosols, was already known before the pandemic: ventilation.

Actually a deeply German virtue and yet, it turns out, there is disagreement about how properly to ventilate. The general public knows three types of ventilation: burst ventilation, cross ventilation and tilted windows. While the first two methods are effective, the latter does next to nothing. The tilted window, that much can be said at the beginning, can be crossed off the list, because air exchange would take forever. What remains is the intermittent and cross ventilation. If office workers have the opportunity, they should use cross ventilation. Because: This is the fastest way to guarantee a complete exchange of air.

“One of them still wears a T-shirt when it’s freezing cold, others freeze even in summer.”

For cross-ventilation, those interested open two windows opposite one another, the air flows into one and the other out. Obvious. The draft is the best way to carry aerosols out of the room. But burst ventilation is also helpful, especially in smaller rooms. Both of these are particularly helpful when the room is well ventilated once an hour for around 10 to 15 minutes – this is the recommendation of the virologists. And this is exactly where the problem often arises, because, as always, it usually struggles with the user. The team almost never decides whether to ventilate or not without minor friction. One of them still wears a T-shirt when it’s freezing cold, others freeze even in summer.

So who decides? Of course the boss, right? The correct answer is: No, it shouldn’t be done by decree. Because when it comes to room temperature, too, an employer has a duty to protect and should ensure that nobody has to freeze unnecessarily. But how are you doing otherwise? First of all, everyone in the team should be convinced of the blessings of ventilation: In addition to the preventive corona measure, good air also has the advantage that on the one hand each person’s ability to concentrate benefits and on the other hand the organs are better supplied with oxygen, which promotes energy conversion.

By the way, CO2 measuring devices are good indicators for air quality. Whether the air is good or bad is another thing that can be argued about. A fairly impartial referee can be found in the helpful gadgets. If the CO2 value in the room is high, this also applies to the aerosol pollution. Because both values ​​increase the more exhaled air there is in the room. It is fascinating to see how quickly the devices turn when there are only five people in a room. Anyone who thinks it is an exaggeration to ventilate once an hour will quickly be taught otherwise. Yes, it makes you breathless!

Just switch to draft

So: The new smoking is not ventilation! Perhaps with this claim one or the other person can be convinced to open the window wide more often. Those who consider the second step will benefit from this: draw up an agreement together – regardless of whether it is based on the general recommendation of virologists or on individual warning signals from a technical helper. If the team draws up a jointly agreed rule and ensures that it is adhered to, there is no stress. Chilblains can expect it to get cold for a moment, and during this time simply go to the company kitchen for a warm tea.

The best way to resolve disputes in the team about ventilation is probably the most effective method: moving back to the home office. There, employees can decide for themselves which benchmark to apply to their air quality, without annoying or endangering other colleagues. The home office, you can’t argue about that, is one of the best methods for office workers to counter the spread of Covid-19. Anyone who occasionally comes to the office for important meetings is certainly more willing to compromise.
