The problems of irrational expenditure of energy resources leading to the depletion of natural reserves of fossil fuels and environmental pollution are considered. The analysis of the main issues considered in the course of improving solar heat supply systems is carried out. Current scientific, practical and statistical data are systematized, in the process of which ways to increase the efficiency of active solar systems are proposed.

he urgency of determining the reliability as the main criterion for the reliability of ventilation systems. The approaches to the determination of the reliability of the ventilation system, the criteria for estimating the parameters of their work, the model of the process of prognosis and improve the reliability of the ventilation systems. Therefore, to quantify the reliability of ventilation systems proposed an approach based on the analysis and evaluation of the physical premises of failures.
