Results of multi-criteria decision making
                        In order to find the best design solution in the building, the AHP and multiple criteria decision-making method COPRAS have been applied. First of all, the results of the survey were analysed.  Fig. 10 shows the results of parameters weights and their priority. The results show that among the three groups of professionals there is a different perception of the importance of the four sustainability parameters. Among the designers, the parameter that most influences their professional choices is the cost, followed by the energetic, comfort and emissions parameter. Among the researchers, the comfort parameter is considered the most important, followed by the emissions, the cost and the energy factor. Finally, the cost parameter is the most relevant for the administrative and technical professional, followed by the energetic, emissions and comfort parameter. To ensure the consistency of the comparison matrix, the consistency ratio (CR) has been evaluated and has satisfied condition CR < 0.1. The results show that the priorities of criteria (and weights) are as follows: cost (0.306), energy demand (0.258), comfort (0.233), carbon dioxide emissions (0.204).
