Abstract: The paper presents the life cycle cost structure of a newly designed office building where the costs of planning, construction, operation and maintenance are analyzed for time periods of 20 and 30 years according to current market prices and reduced to net present value. The results of the life cycle cost analysis show that for a period of 20 years, the shares of initial or capital costs and operation and maintenance costs are approximately equal. For a period of 30 years, the share of capital costs is 42.6%, and the share of operation and maintenance costs is 57.4%, which exceeds capital costs. These results confirm previous research and the significance of the operation and maintenance costs, and indicate that in engineering practice in the design stage it is necessary to analyze and calculate the total costs of the life cycle of buildings for the purpose of evaluating variant solutions.

Keywords: life cycle costs of buildings, capital costs, operation costs, maintenance costs
