Purpose
This study evaluates natural ventilation under normal conditions at two daycare centres. Indoor air temperature, air circulation, intensity of turbulence and air change rates were investigated in particular. The authors’ motivation for this study is the fact that children spend a significant amount of time indoors when in daycare, and therefore the indoor climate is important for their health.
Result
The indoor air temperatures in buildings A and B were compared and were found to be almost identical. High levels of CO2 were measured in both buildings, and these levels were often close to, or higher than, the maximum accepted value. The authors call for systems that make it possible to avoid these high values. The study concludes that on the basis of these pilot studies, further research is needed in order to obtain more knowledge about the indoor climate and air quality, ventilation capacity and energy requirements. Furthermore, analysis of the performance of ventilation systems as well as strategies for controlling indoor climate, is required in situations where special emphasis is on indoor climate perspectives related to children aged between zero and six.
Design
The study is a pilot study. The ventilation in two different buildings was measured. In building A, there was a hybrid ventilation system, whereas natural ventilation was the only form of ventilation in building B.
