ABSTRACT

In buildings’ life cycle we are often confronted with issue either to renovate the building or to build a substitutional building. In the construction market there is a problem of increasing the number of unsold apartment houses and other buildings. Regarding to high number of new buildings these are older buildings which become evenmore neglected and unadopted because of unuse. Finding the heigh of renewal’s costs (regular maintenance) and sanation of existing buildings, in comparison with costs with possible construction of substitutional buildings in sense of their economic justification, have not been a part of wider discussion so far. Thus we are developing multiobjective decisive model, which will help at accepting the decisions of owners either to renovate the building or to build substitutional building if this is economic justificated considering the criteria of physical deterioration and functional and economic obsoleteness in connection with the value of the building and profitability or benefit. It is the definition of time limit in lifetime of building until it is still justificated to renovate or sanitate it considering also higher profitability or benefit which will be achieved by substitutional building.

Keywords: Physical deterioration, Functional obsolescence, Economic obsolescence, Renovation, Substitutional construction, Demolition.
