Life Cycle Equivalent Annual Cost (LCEAC) as a Comparative Indicator in the Life Cycle Cost Analysis of Buildings with Different Lifetimes

The paper deals with the issue of the life cycle cost in the construction. It also focuses on the part of the model for the calculation of the life cycle cost of buildings with consideration of the risk that allows the calculation of the life cycle cost of buildings with different lifetimes. For the construction of this part of the model, the authors used the life cycle equivalent annual cost indicator (LCEAC). The operation of this part of the model was presented on the example of three scenarios of the life cycle of pneumatic sports halls for which the estimated service life of the building (ESLB) was ranged from 19 to 30 years
