A lot of data had to be processed and evaluated in carrying out multivariant design and multiple criteria analysis of a building life cycle. The number of feasible alternatives can be as large as 100 000. Each of the alternatives may be described from various perspectives (economic, technical, qualitative, technological, social, legislative, infrastructural, etc.). The problem arises how to perform multivariant design and multiple criteria analysis of the alternative variants based on this enormous amount of information. To solve this problem the methods of multivariant design and multiple criteria building life cycle analysis were developed. In order to demonstrate the theory an example is given in this paper.
