[Indoor climatic conditions of the floor zone in child nurseries]

The room climatic conditions in the near floor zone were measured in creches. The surface temperature of the floor during the heating season did not reach the desired range of 20 to 22 degrees C. 59% of the measured minimal values, 39% of the mean values, and 18% of the maximal ones were about 15 degrees C or even drastically lower. Of the air temperature in the near floor zone (at a level between 0.15 m and 0.50m) 31% of their minimal values at the level of 0.15 m and 27% of their minimal values at the level of 0.50 m values were below 16 degrees C. The investigations of the vertical temperature gradients during the heating season showed that only 9% of the values measured between 0.50 m and 1.50 m meet the required standard of 1 degree C temperature difference per meter. Conclusions are drawn and discussed.
