Profitability Analysis and Assessment of the Possibility of Applying Renovation and Modernization Measures to Improve the Utility Value of Public Buildings

Abstract

Abstract Utility building value depends, among other things, on the renovation and modernization activities undertaken at the maintenance stage. They result from a correct assessment of the building condition. Lack of appropriate methods, which in a comprehensive way, taking into account the utility requirements for these buildings, would allow to assess the condition of buildings is one of the main reasons for negligence in the proper maintenance of public buildings. With this in mind, the author carried out a study aimed at an in-depth analysis and assessment of the possibility of applying renovation and modernization measures in relation to the improvement of the utility value of the building and the cost of their implementation. As part of the research, a mathematical model was first developed, which was used to carry out the research. As part of the development of the model, a set of criteria relating to technical-utility, economic and environmental requirements was selected and a method for their evaluation was developed. Next, proposals of renovation and modernization activities were presented, the aim of which is to improve the utility value ratio of the building. For its evaluation the method based on the theory of fuzzy sets was used, which at the stage of inference uses expert knowledge included in the fuzzy rules database. The calculated utility value of the proposed renovation and modernization activities is the basis for further research analyses. Optimization tasks consisting in the selection of an appropriate repair variant are carried out by means of appropriate optimization methods. The adopted optimization objectives concerned both the possibility of improving the assumed increase in utility value and limitations in their financing. The assessment of utility value of public utility buildings, which has not been carried out yet, taking into account the current legal and utility requirements, will allow to determine the impact of renovation and modernization decisions taken on this basis on the adopted determinants determining the quality of the maintenance process, i.e. the increase in utility value and maintenance cost. The results of these studies may be important in expanding existing knowledge and the knowledge gained may contribute to changes in the way decisions are made and the improvement of the quality of building maintenance.
