The main topic of research within this work comprises of climatic differences between container classes and ordinary classrooms.
The chosen schools are all located in Lower-Austria and were either newly built or have been renovated during the last nine years. Temperature and relative humidity variations over a period of five months of February till June 2011 and indoor carbon dioxide levels during June 2011, make up the main bulk of the experimental data. These factors were chosen for their significant influence on the performance of the pupils and teachers. The outdoor -temperature and -humidity was obtained from the Zentralanstalt für Meteorologie und Geodynamik and the rest of the required data such as the absolute humidity and operative temperature were calculated by the author. The teachers in each school were handed a questionnaire containing information such as their ventilation method, air quality, temperature comfort and the degree of the humidity in the classrooms.
During the heating season, an excessive heating of the container schools was observed. In general the normal (non-container) schools had all acceptable temperature values except during the early morning hours, where the heating system still had not managed to warm up the air to the standard temperature. The absolute humidity and CO2 values in June show that the ventilation of the schools and the container-based schools in particular, had not been as effective as necessary. The measured values indicated that the temperature and also the carbon dioxide values of the container classes vary considerably during the school opening hours.
These findings about the container classes were made more obvious through the psychrometric charts and the high percentages of data points which lay out of the range specified by Austrian norms.
