Model supporting decisions on renovation and modernization of public utility buildings

The aim of the research is to develop a model to support renovation and modernization decisions in the process of maintaining public buildings. The scope of the research includes, first of all, the development of a method of building assessment on the basis of many criteria, applied also in the evaluation of residential buildings, but also specific ones, related to public utility facilities, i.e.: environmental compatibility of buildings, adaptation to the elderly and disabled, fire safety. On the basis of this assessment, a set of proposed renovation and modernisation measures will be determined. In the next stage, knowledge will be acquired from experts (including property managers), who will indicate the ranges of criteria values for the adopted assessments of building utility value. This knowledge will be used to build a rules base of fuzzy inference system for assessing building utility value. The next stage of research will be conducting computer simulations with the use of a mathematical model assessing the impact of the above mentioned decisions on the increase in the building utility value and the renovation cost and modernization activities. All calculations will be carried out in the Matlab Simulink environment with the use of optimization and fuzzy methods. Knowledge of the relationship between decisions on the scope of renovation and modernization solutions and the quality measures of the maintenance process is the basis for decisions in the area of buildings maintenance. The results of these studies can contribute to improving the quality of maintenance of public buildings.
