The paper presents a model for selection of building’s external elements. Were analyzed 6 variations of walls and windows area ratio. The authors determined the criteria of those alternatives, which are as follows: heat losses through the building external walls, heat losses through the building windows, heat losses through the bearer thermal bridges, heat losses above the rated air infiltration, external heat inflows in the building from the outside, the building’s energy consumption without consideration of heating system performance, and walls and windows price ratio. According to available data, the initial matrix of a problem was determined. By the use of multiple assessment methods, such as SAW (Simple Additive Weight) COPRAS (Complex Proportion Assessment) and MEW (Multiplicative Exponential Weighting) were calculated the optimal variant of a window and wall aria variation.
