Abstract
Historic buildings that have survived to the present day have been subject to maintenance, repair, and overhaul. Repair work is being carried out so that it can be enjoyed by future generations. However, there have been changes in the construction technology: some construction products have been discontinued and replaced with others of different quality parameters, lower prices, etc. It is necessary to use substitute products during construction work—that is, replacement products that are shaped after the original. Therefore, there is a problem of selecting the best possible substitute material, taking into account many important factors, including the recommendations and requirements of the conservator. This paper presents a methodology for the process of material substitution planning and selection of a substitute with the use of multicriteria analysis, by implementing it in the refurbishment of a historic building façade.

Construction artefacts are characterized by a long life cycle
Substitution of construction products is a common practice at every stage of the life cycle of a building
Substitution occurs in the further exploitation of facilities, especially when carrying out any repair and refurbishment works in facilities used for Substitution of construction products is a common practice at every stage of the life cycle of a building
Summary
Construction artefacts are characterized by a long life cycle. The longest phase of this is exploitation. The authors focus on the application of the possibility of construction products substitution. This solution might be needed due to variables such as the object’s standard improvement, cost conditions, and limitations resulting from the lack of original materials available during construction. The latter aspect applies in particular to refurbishment works carried out on buildings found in the inventory of historic buildings
