  1. 1. Energy retrofitting effect on perceived indoor climate: A case study of Estonian multi-family buildings

    Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Kadri Reinumägi; [2023]
    Nyckelord :Indoor environment; Thermal comfort; Indoor Air Quality; Window airing habits; Energy renovation; Occupant survey; Technology and Engineering;

    Sammanfattning : Energy renovations are an important measure for achieving the European Union’s target of climate neutrality by 2050. To meet the EU goal, Estonia needs to fully renovate 14 000 multi-family buildings by that time, affecting the indoor environment conditions of a large number of people. LÄS MER
