ABSTRACT. Apartment building thermal rehabilitation impact on indoor carbon dioxide releases. This article continues the research presented at the last year conference by Kapalo et al. (2017) in the article "Renovation of the building and its impact on air pollution". The main purpose of this study is to quantify the amount of carbon dioxide produced inside an apartment building with 90 occupants, before and after the thermal rehabilitation process. As expected, the improving actions on building thermal insulation had a positive effect on energy consumption and, as a consequence, the CO2 footprint of the building decreased significantly. After changing the old wooden windows with new tight ones and after using a heat recovery air handling unit, the values of CO2 production were reduced by 48%, as resulting from the conversion of energy savings due to heating of the building. After applying the thermal insulation on building envelope, the equivalent CO2 releases of the apartment building were reduced to a final value of 40% compared to the CO2 footprint before the building thermal rehabilitation.
