The paper focuses on comparison of indoor conditions in one of Warsaw's (Poland) kindergarten, before, and after installation of humidity controlled air inlets. The kindergarten is located in an old, one storey building with natural ventilation, where old, wooden windows were replaced with new, plastic, air tight ones. Firstly, indoor temperature, relative humidity and CO2 concentration data were gathered with data loggers for a period of one month during winter. Then, the measurements were repeated after installation of humidity controlled air inlets. The analysis of measurements showed significant improvement of indoor air quality and ventilation rate, after the installation of air inlets, but still not good enough to meet accepted standards. Also the yearly children absences before and after modernization of ventilation system were monitored. Although the indoor air quality was significantly improved the absences (also short term absences) did not change.
