The paper focuses on comparing the indoor climate in a modern apartment building with mechanical balanced ventilation system to a building with natural stack effect ventilation. The results of 9-month measurements of CO2 concentration level, indoor air temperature and relative humidity are presented. Overall, the CO2 concentration level in the building with the mechanical balanced ventilation is significantly lower in winter and comparable in the summertime. The indoor temperature in building with natural stack ventilation was lower during the cold period. The relative humidity level is closer to preferable in the building with stack induced ventilation most likely due to lower airflow rates.
