【 摘 要 】

The LCC analysis can be applied to assess effectiveness of construction variants or acquisition of new facilities as well as modernization of the existing ones. The authors of this paper intended to apply the LCCA method at analysing a building in the final stage of the building life cycle (grade phase). The authors decided to create and analyse costs for three scenarios assuming combination of a preventive strategy that stops the deterioration of the building's condition with three alternative end-of-life-cycle possibilities: Scenario I - preventive maintenance together with the demolition of the object; Scenario II - preventive maintenance together with the deconstruction of the object and recovery of some materials; Scenario III - preventive maintenance and sale of the object at the set point of the life cycle. An energy-efficient single-family detached residential building was chosen for the analysis. The results show that differences between LCNPV are not significant. Nonetheless, the authors suggest investors to be aware of the possibilities of the last phase of the life cycle of a building and their financial consequences.
