Thermal Comfort and Indoor Air Quality after a Partially Energy-efficient Renovation of a Prefabricated Concrete Kindergarten Constructed in 1980’s in Slovenia

The majority of kindergartens situated in the territory of former Yugoslavia need renovation. Apart from their enhanced energy efficiency, renovated buildings will presumably offer better indoor environmental quality. According to the current case study, children using a classroom with new windows installed are exposed to substantially poorer indoor air quality due to airtightness and improper ventilation, which calls attention to a vital technical issue of the current renovation process.
