This has not been the case in the past, but nowadays there is a growing awareness of the disadvantages of such thinking through the excessive costs of maintaining and using a building after its construction. Therefore, architects, designers and investors today can greatly reduce the future cost of maintaining and using a building at the design stage. Of course, with the installation of quality elements and materials and the proper execution of works, the percentage reduction in the future total living costs of maintaining and using the building is only increasing.The main task of this paper is to present and make a plan for the maintenance of a public purpose building for a period of 25 years, that is, in the period 2019-2043. The public purpose building selected for this work is the IGK Student Hall. In the preparation of this diploma paper, the net present value method and the sensitivity analysis method were applied with the help of which the change of key factors has an impact on the overall maintenance costs. In addition, all groups of maintenance costs for this type of building are described.
