Evaluation of Alternative Building Designes According to the Three Criteria of Optimality

The purpose of this article – is compare different designs of building or its structure and to select the best alternative using criteria of optimality. These three criteria make possible to evaluate design solutions which can be charac-terized by quantitative and qualitative criteria which possibly have different weight, dimension and direction of optimization (maximization or minimization). Case study is demonstrated by selecting the best facade system to cover the building. For this purpose four alternatives of building facades are under consideration. Two criteria (out of three) indicate that for the case study the most preferable facade‘s alternative is gas silicate masonry, covered by Roockwool and “Minerit” facade plates
