Renovation (modernisation) of buildings is one of the priority areas of EU cohesion policy. Growing prices for energy resources as well as living, working and leisure environments that do not conform to requirements of hygiene norms encourage the public to take more efforts towards participation in the process of building renovation.

The dissertation aim to create a theoretical model for the assessment of efficiency of building renovation based on multi-attribute decision making methods and use it in practice with results of investigations made on public buildings (kindergartens) before and after renovation.

The dissertation comprises an introduction, three chapters, general conclusions, lists of literature, resources and publications of the author on the topic of the dissertation, abstract in English and three annexes. The introduction specifies the problem, describes the relevance of the paper, the research object, aim and objectives as well as methodology of the research, its novelty, practical significance of results, and defended statements. Finally, it lists publications and conference presentations produced by the author on the topic of the dissertation and presents its structure. Chapter one is dedicated for literature (scientific publications and legislative acts) analysis. It provides classification of structures according to their intended use and lists factors determining renovation of buildings; describes the analysis into renovation of public buildings; presents the concept of multi-attribute decision making and classification of multi-attribute decision making methods; and specifies the adjustment of multi-attribute methods for construction engineering. Chapter two focuses on design of the model for assessment of the efficiency of building renovation. It presents the model based on the use of multi-attribute decision making methods. The chapter underlines the key attributes for assessment and indicates methods used for determining attribute weights as well as those used for multi-attribute assessment and summarising the results; additionally, it presents methodologies for field experiments conducted in researched buildings. Chapter three is dedicated for adjustment of the designed model for assessment of the efficiency of building renovation. It details field experiments delivered in four public buildings as well as calculations for stages of the designed model to identify the best alternative. The end of the chapter provides the analysis of assessment results.

Nine research articles were published on the topic of the dissertation: two in scientific journals included into Thomson Reuters Web of Knowledge (ISI Web of Science); two in scientific journals included into other databases; two in ISI Proceedings; three in Lithuanian conference proceedings. Five presentations were given on the topic of the dissertation in four scientific conferences.
