Abstract:Increasing requirements for reducing energy consumption result in ther-mo-modernization of the existing buildings. Modernized buildings have significantly lower heat transfer coefficient; simultaneously the infiltration through the windows slows markedly, which may deteriorate indoor air quality (IAQ) seriously. ; The measurements are done in a lodging room of a three-room dwelling in a sixty-year old building after thermo-modernization; one gauge with a vane probe measures the air velocity and tem-perature at a grille in the toilet; second gauge with IAQ probe located in this room measures the mole fraction of carbon dioxide, air temperature, absolute pressure, and rel-ative humidity; moreover there are estimated the uncertainties of: the volume flow rate, mole fraction of CO2, temperatures, and humidity. Heating system ensures thermal com-fort during heating season; despite of proper ventilation performance in the toilet the IAQ in the logging room is low, for vapor condenses on the window; carbon dioxide concen-tration is too high, which curbs mental activity greatly.
