Purpose. Researching the most energy-efficient warming construction system of buildings among the commonest of them, using their technical, technological and economical characteristics. Methodology. Synthesis, analysis, mathematical methods. Findings. For choosing effective technology, information analysis of systems warming of facades was made. Three types were chosen from the most prominent technics. Technical and economical calculations were made for these systems. Originality. Enhancement of the counting approach whereby the selection of the most suitable variant is making by a few points, which doesn’t exclude each other. Practical value. Discovered is, for the optimal choosing of the warming construction of the facade, there is an importance to use a few technical and economical records at the same time.
