Indoor air quality is gaining on its significance when designing new buildings. Buildings have to be energy efficient and independant. One of the important aspects in this matter ventilation. Insufficient ventilation system can cause problems with poor indoor air quality, which can reflect in user dissatisfaction.
A comparitive study of indoor air quality in prefabricated and classically built kindergarten is the forefront of this graduation thesis. Objective evaluation of indoor air quality was estimated by site measuring (CO2 concentrations, relative air humidity and air temperature) and calculations. Subjective evaluation was conducted through questionnaires.
The results show that indoor air quality in both kindergartens is poor. Better values of CO2 concentrations were obtained at prefabricated kindergarten. Air flow is better in classically built kindergaten. Calculated and measured CO2 concentrations are comparative. The results
of questionnaires partially confirmed the measures and calculated results.
Values of the CO2 concentrations rarely reach required values of Ventilation and airconditioning regulations for buildings. All measurements shows low and insufficient air flow. To improve indoor air quality in both kindergartens, the ventilation habits or ventilation type should be changed.
