The aim of the article is to evaluate the actual situation of thermal comfort in old non-modernized and modernized kindergartens in Lithuania. In this case, the level of thermal comfort and air quality of two modernized and two non-modernized kindergartens is ana- lyzed. In order to evaluate the level of comfort and air quality of the kindergartens, the air temperature, relative humidity and CO2 levels in the air were measured. The study follows the EN ISO 7730 International Standard’s methodology based on Fanger’s Comfort Model. The results of the research presented in this article are supported by the indicators of thermal comfort and CO2 concentration values. According to the calculated average thermal comfort values, the thermal comfort level of two mod- ernized kindergartens and one non-modernized kindergarten falls within the bounds of the comfort zone. Though, the results of CO2 concentration measurements show that in all the kindergartens during the working days CO2 concentration always exceeds the standard requirements.
