Indoor climate, one focused issue at Nordbygg

The next generation is spending a great deal of their time at school, an environment where knowledge and learning characterises the day. To give children and adolescents the best possible future, a good indoor climate is a prerequisite.

A good indoor climate is a prerequisite for good health and is of great importance for a functional school environment. Poor ventilation affects the ability to learn in a negative way through among other things difficulties in concentrating, fatigue and headaches. With the right temperature and air quality in the classroom, students can reach better results.  

– There is a clear correlation between ventilation and performance. An older study from Denmark shows that performance increases if the air flows in the school increase. It also showed that performance in mathematics and reading comprehension decreased when the air supply was less than 6-7 litres per second and person. If ventilation flows that are already low where to be doubled, performance can be increased by 14.5 per cent, says Britta Permats, CEO of Svensk Ventilation.  

Ventilation in schools therefore plays an important role in children’s ability to learn.  

– Our future is in our premises and we must take care of them. On our part, we have to measure all the factors that indicate good air and ensure an indoor environment that enables good learning. Pupils should be able to focus on their education without having to think about whether it is too cold or if there is a funny smell, says Niklas Dalgrip, Operations Manager at SISAB, Skolfastigheter i Stockholm AB.  

New technology facilitates good air 

In general, good air is about lowering the amount of pollutions that are hazardous to our health and see to it that there is no oppressive air. To ensure good ventilation, there are many factors to consider, says Britta Permats. 

– For example, having low-emission construction materials, ensuring that it is damp proof and that the amount of radon is not too high, as well as having correct ventilation flows. The CO2 level should for instance not exceed 1000 ppm over a longer period of time, since it is an indicator that the ventilation is not good enough. If the CO2 levels are too high, there are often other pollutions as well, says Britta Permats. 

To facilitate good ventilation, we need new technology and innovations. Sensor technology is something that SISAB has developed and worked with the past few years.  

– To ensure a good indoor climate, we need to maintain the existing properties and use new technology. The sensor technology has given us completely new possibilities to guarantee that we are doing it right. To measure is to know, and the sensor technology enables that in quite a different way than was previously possible, says Niklas Dalgrip.
