In the context of the development of energy-efficient construction production, the issue of eliminating the irrational consumption of fuel and energy resources and regulating their consumption in the course of construction and installation work, including the demolition of an object, has been updated. The article discusses the features of the production of dismantling works in the process of renovation of residential buildings, taking into account the consumption of fuel and energy resources by the main consumers - means of mechanization. On the example of a five-story brick residential building, the total energy consumption during demolition by the method of mechanical collapse and element-by-element disassembly with the preservation of suitable materials was determined, and the relationship between these two options was established. The calculations showed that the consumption of fuel and energy resources during the element-by-element dismantling of all building structures with the preservation of suitable materials for brick heated buildings is 55.3% less compared to dismantling the building by the collapse method; in monetary terms, the energy costs for option 1 exceed the costs for option 2 by 1.55 times.

The possibility of using neural networks to classify the states of complex objects is considered. A software implementation of a neural network classifier is made and the results are compared with a selection algorithm based on K-nearest neighbors.
