Indoor environment of the renovated building

Building renovation is necessary not only for the maintenance and operation of the building itself but also helps to reduce energy requirements and indoor environmental quality (IEQ). The aim of this study is to determine the condition of IEQ in renovated building through quantitative and qualitative determination of physical and chemical factors. The analytical results showed no significant concentrations of CO or TVOC; however, the concentration of PM10 exceeded the limit by a factor of 4.77. The highest value of CO2 concentration was 740 ppm, so the limit value 1000 ppm was not exceeded due to the fact that no users were present during the measurements. The illumination of the cultural center premises is sufficient.
