Abstract:

Depending on the place of residence, social status, education or preferences, investors make various decisions regarding the construction material. As far as the functional characteristics of individual materials are known, the factors that govern decision-makers in the choice of construction material for building construction are not fully known. In the article, the authors have therefore attempted to find these criteria and to investigate causal relationships between compressive strength, acoustic insulation, economy, ecology, thermal conductivity and fire safety. The main aim of the article is also to find answers to the following questions: which criterion is decisive? What impact do the individual criteria have on each other? Whether and to what extent ecology influences on the decisions that are made? Unlike the traditional multiple criteria decision-making techniques which typically assume the criteria are mutually independent. By applying DEMATEL method, the importance of six criteria can be determined and the causal relations among the criteria can be constructed. The most important factor in the choice of construction material is price, and in the second place is ecology. The compressive strength (K1) and thermal conductivity (K5) have a strong impact on the other criteria. K1, K2, K5 and K6 have a strong impact on ecology (K4) and economy (K3). However, it should be emphasized that the least affect by fire safety (K6) and sound insulation (K2).
