Building status obtained before renovating multifamily buildings in Sweden

Farsäter, Karin LU ; Strandberg, Paulien LU and Wahlström, Åsa LU (2019) In Journal of Building Engineering
Abstract (Swedish)
The aim of this study was to analyse how energy use, building physics properties and indoor environment data have been obtained in the initial evaluation phases of multifamily building renovations in Sweden. Between 1964 and 1975, approximately one million homes were built in Sweden. These buildings are now in need of renovation. To perform proper status assessment of a building before a renovation is important both to make decisions on renovation measures on correct information as well as to be able to perform follow-ups of renovation projects. The analyses in this study was performed with questionnaires in eight case studies. Studied data included energy use, building physics properties and indoor environmental factors. The study shows...
