This article discusses unresolved scientific issues in assessing the energy efficiency of industrial facilities and compares it with the widely used approaches for residential buildings. The study employed expert surveys and statistical analysis to determine energy efficiency indicators and their weights for different groups. The research resulted in the positioning of energy efficiency classes based on experimental data.
This article examines the issues in assessment of the energy efficiency of industrial facilities, which have not yet been scientifically resolved, in contrast to the widely used approaches to assessing residential buildings, which are similar in many countries of the world. The sequence of the study was determined in combination with the characteristics of the methods used, the leading of which was the expert survey method. Based on the analysis of the collected statistical information, the significance of energy efficiency indicators was agreed upon and assessed for three groups: first-industrial building, second-technological processes, and third-ensuring the environmental friendliness and energy efficiency of an industrial facility. The weight of each group was also determined based on an expert survey. This made it possible to calculate the specific weights of the indicators and formulate a rating scale. The principle of assigning points for each indicator is determined depending on the deviation of actual values from standard values for quantitative indicators and according to the characteristics of the object of analysis for qualitative indicators. The result of the study was the positioning of classes on the scale of energy efficiency within the established boundaries based on experimental data.
