Optimal indoor environmental quality (IEQ) is especially important in every living and working environment with present vulnerable population groups. Especially problematic are educational institutions, where prolonged exposure time of users additionally increases health risks. The present study is focused on the problem of deteriorated IEQ in renovated kindergarten. The problem was critically assessed from the aspects of indoor air quality (IAQ) and energy use. A combination of simulations of the selected IAQ parameters and building energy use was performed for five sets of scenarios, where required and recommended design ventilation rates variated according to Slovenian legislation. Characteristics of actual kindergarten in central Slovenia, renovated in 2016, were used for simulations. Concentrations of CO2 and formaldehyde were calculated in two model playrooms with CONTAM 3.2, whereas building energy use was calculated for two thermal zones of playrooms with Energy Plus 8.0.0. If ventilation in playrooms was designed according to the minimal permissible value (air changes per hour) ACH 0.5, CO2 concentrations exceeded the national maximum permissible level by 2.5 and 3 times, and formaldehyde concentrations was close to the value recommended by World Health Organisation (WHO) and exceeded the level recommended by National Institute for Occupational Safety and Health (NIOSH-CDC) by 4.6 and 4.5 times. All required and recommended design ventilation rates resulted in exceeded values of CO2 above recommendation for category I of IAQ, except the design ventilation rate 55 m3/h per person. In-line with public health protection measures, relevant information is an aid for recommendation definitions for policies and strategies towards healthier indoor environments as well as for raising awareness about current design practice.
