Automated Evaluation of Alternative Solutions of Building Design

The purpose of this article – is to create theoretical model in order to enable in automated manner to compare different solutions of building, its part or structure design and to select the best alternative under specific circumstances. Summarizing variant design theory and practice applications in Lithuania and abroad, evaluation model of alternative design solutions is created. By assistance of this model it will be possible to evaluate design solutions which can be characterized by quantitative and qualitative indicators which possibly have different weight, dimention and direction of optimization (maksimization or minimization). Automated alternatives’ evaluation working principle is demonstrated by selecting the best facade system to cover the building. For this purpose four building facades alternatives is under consideration. It is soundly described how all stages of alternatives comparison is performed and which multiple criteria evaluation methods can be applied by selecting the best alternative.
