The thesis presents the procedure for the whole life-cycle costs assessment of a building.
Special emphasis is placed on risks associated with decisions in sequential stages of the
construction project: concept, design, construction, operation and end of life.
Risk management, i.e. types of costs and associated risks generated during construction
project, risk identification, allocation and responsibility, is discussed. The whole life cycle
cost analysis (WLCC analysis) is described together with different methods of life cycle costs
prediction. Decisions and the associated risks are presented for each project stage. Possible
risks and adequate responses to these risks are sytematically presented in tables.
Chapters discussing the theory of WLCC analysis and associated risks are followed by the
case study were WLCC analysis was conducted for the selected building. Management,
maintenance and operation costs were calculated by using the existing software package for
the time period of 15 years. The results show that the heating and maintenance costs represent
23 % and 44 %, respectively, of the total operation costs for the analysed building. In
addition, a parametric analysis of whole life cycle costs for a simplified case of a window
frame material variation was carried out. Different types of frames result in different life cycle
costs which include the product price together with the heating and maintenance costs at equal
