The subject of the thesis is the 10-year-old container kindergarten called Mojca in Grosuplje, which was built as a temporary solution to the spatial distress. The motive for the thesis was a warning by the kindergarten users about the poor indoor environmntal quality that they have perceived (inadequate air quality, temperature, illuminance and excessive noise level).
Article 57 of the Rules on standards and minimal technical conditions for kindergarten premises and equipment has enabled the resolution for spatial distress by temporary mobile units for a period of a decade. The change of the article in 2016, however, prolongs the use of facilities for educational activities for additional 10 years. Considering the users' warnings, we wanted to check whether the Mojca mobile unit is suitable for further use.
The method included a combination of the following activities: 1. an overview of researches, legal acts and recommendations in the field of the indoor environmntal quality parameters; 2. in-situ measurements of the selected parameters of the playroom interior; 3. user surveys on interior conditions and the possible appearance of sick building syndrome symptoms and; 4. data analysis with identification of problems; 5. the definition of the measures.
Measurements were carried out between 22 February and 14 July 2018, in order to identify winter, spring and summer conditions in the facility. To compare the influence of light prefabricated construction to solid construction on the indoor environmntal quality parameters, we carried out the same measurements in the Rožle unit, which is located on the ground floor of an apartment block, which is a solid construction. On the basis of field measurements, we analysed the adequacy of the indoor environmntal quality parameters in comparison to the current statutory provisions.
The thesis was approved by the Slovenian National Medical Ethics Committee. Measures to improve the quality of the interior were based on participatory planning.
We identified inadequate temperature conditions (surface temperature, air temperature and operative temperature), too low relative air humidity, excessive CO2 concentration, and excessive noise level. Sick building syndrome symptoms are more common among users in the Mojca unit than in the Rožle unit. The results of the analysis show that, in order to protect and secure children, employees and visitors, complete measures are needed in the Mojca unit facility. We also recommend to improve the indoor environmental quality in the Rožle unit.
