Are Our Children Gasping for Air?l
Why good indoor air quality is important
within the scope of Germany’s Stimulus Package II
As society has changed in recent decades, the day-to-day lives of children have been changing as well. They are spending increasingly more time in children’s preschool facilities and school (not least because more and more are spending the entire day at such facilities) and they are expected to meet rising performance standards, especially at school. However, their developmental and learning processes cannot proceed optimally unless their brains receive enough oxygen.
For schools and preschool facilities, this means that the necessary conditions are not met unless the air in their classrooms and recreational rooms is of sufficiently high quality. Reality shows us, however, that this aspect is increasingly coming to the attention of decision-makers, but up to now a comparatively small percentage of facilities fulfils the requirements for an air supply that is suited to those needs.

Energy-efficient renovation of schools and preschools
The funds that the German federal government has recently made available from its Stimulus Package II are intended to be used for the comprehensive renovation of buildings. The better part of this total is to be used for renovating children’s preschool facilities, schools and universities. This sets a clear impetus for environmental protection and energy efficiency.
In addition to saving energy and reducing expenses, it is also intended that the renovations will reduce the concentration of CO2 in the indoor air. However, the standard method of ventilation – opening a window – does not provide an ideal indoor environment. This also leads to a heat loss, particularly in renovated buildings.

Stale air in the classroom?
Developmental and learning processes proceed optimally when the CO2 level of room air does not exceed the recommended guideline of 0.15 volume percent, according to DIN 1946 part 2. If the CO2 level exceeds this value briefly, the person’s overall state deteriorates, and it can cause headaches and difficulties in concentration. Exceeding the limit for longer times can lead to chronic illnesses such as asthma or allergies. This is especially true when the indoor air also contains harmful substances.
Thus, in order for the developmental and learning processes of young persons to proceed optimally, their brains must receive enough oxygen. This can hardly be achieved through the standard solution – ventilating by opening windows. The
most effective methods of ventilating manually – cross-ventilation and opening all windows fully – are often accompanied by drafts and problems due to noise, which result in difficulties during the class session. Because of this, the rooms can be ventilated only during breaks, and the required limits cannot be maintained. In addition, intensive ventilation by opening the windows, especially during the winter months, can go hand-in-hand with noticeable heat losses and unnecessarily high expenses.
