In the article the author develops uniform integrated criterion of fibrous heat-insulating materials assessment, which reflects all the aspects of their life cycle. When developing such criterion both computational and expert methods of assessment are used. The uniform ecological safety assessment system will allow to carry out assessment of materials of heat-insulating application adequately beginning with the scientific point of view at all levels and stages of the life cycle from specifying competitive strength of the uppliers in the market and to an ecological situation in the given area.When developing the uniform criterion the author uses the approach offered by Charles A.S. Hall (State University of New York) for efficiency assessment of fuel production (energy return on investment — EROI). The offered criterion provides the analysis of thermal energy quantity, which allows to keep a heat-insulating material throughout the year, the energy referred to expenses on life cycle of a considered heater. As a methodical base for calculations the methods of the theory of risks can be used (Elmeri, Fine-Kinney methods, etc.), an important role is played by quality management methods (for example, creation of charts of Walter Andrew Shewhart). Besides, there already exist acknowledged methods of building materials assessment: methods of parameters grid generation, ecological sieves, ecological trace, backpacks with impacts on environment, etc. The most important factor of the analysis of an offered indicator is discounting of the indicators connected with economy or expenses of energy resources as it allows to increase objectivity of an assessment. Besides, the article offers the way of analyzing emissions of greenhouse gases throughout life cycle of heat-insulating materials. In particular, it is offered to count the decrease of greenhouse gases emissions by reducingenergy consumption taking account for the number of emissions of COlife cycle.on the whole
