The most of multi-apartment residential houses in Lithuania were built before 1993. Most of these houses are uneconomical, unecological and consume a significant amount of heat energy. Such multi-apartment houses need to be modernized, and, therefore, it is important to examine and analyse their state. This paper discusses the state of structural elements of multi-apartment houses, their deterioration level, heat energy losses, as well as the problems of microclimate in the premises, layout and living environment. Modernization of buildings is effective only when the state of buildings is carefully analysed and the most suitable renovation method or scenario is selected.
