The technical and economic efficiency actual problem of the use of building materials, products and structures is considered. Taking into account the purpose, a grouping of building materials was carried out according to eight nomenclature groups of structural, structural and heat-insulating, heat-insulating, acoustic, finishing, waterproofing and roofing materials, as well as the materials for special and general purposes. It is proposed to assess the technical and economic efficiency of building materials that form various nomenclature groups on the basis of two methodological approaches. The first approach should be applied to the building materials with one pronounced functional property, and the second - for the materials with several properties, the priority of which is not obvious. The calculations are carried out according to the criterion of the maximum units of useful effect due to the use of materials per unit of associated costs. In the second case, it is advisable to use the expert assessments to determine the significance of functional properties. Methodical recommendations for the technology of their implementation are provided.
