“…It was noticed that about 84% of changes in the seasonal heat consumption CH depends on the changes in thermal power q, while 16% does not depend on the changes of this quantity [5]. This state can be caused by not very accurate consideration of the actual conditions of buildings' heating in the methodology of thermal power q calculation.…”

“…The value of energy consumption CH is the effect of, inter alia, the duration of the heating season and the conditions inside and outside of a room. The obtained results of calculations (for example Qk,H) should correlate with the results of measurements (measured directly or indirectly) (CH) [2][3][4][5][6][7]. The connection between discussed quantities should be the stronger, the better are rendered the heating conditions and the specificity of an operated object.…”

“…The author in his earlier studies [4,5,6] analyzed the relationship between the seasonal consumption of heat for heating educational buildings and the peak power needed for heating. It was noticed that about 84% of changes in the seasonal heat consumption CH depends on the changes in thermal power q, while 16% does not depend on the changes of this quantity [5].…”

Abstract. The calculative methods, which are adopted in various fields of engineering, are usually a certain kind of theoretical approximation of reality. The deviations from a full consistency of actual conditions and theoretical assumptions occur also in case of building heating. This work presents the selected results of examinations connected with an annual energy consumption C H and annual final energy demand Q k,H for heating and conducted on the group of educational buildings. The presented analysis and its results regard the group including 46 of 50 educational buildings, which form a municipal group of the buildings of this type. The purpose of presented analysis was to examine the influence of possible occurrence and level of differences between the annual energy consumption C H and annual final energy demand Q k,H for heating of examined buildings. The realization of this purpose is the basis for further research and analysis aimed at determining the dominant reasons of mentioned differences, establishing their level and propose a calculative method for reducing the differences between the values "picturing" the thermal needs of educational buildings in actual (energy consumption C H) and theoretical (final energy demand Q k,H) conditions.

“…In addition to providing comfortable conditions in the room, an important role is played by the technical and economic evaluation (Aedah, 2018) of the efficiency of the ventilation systems. Therefore, thermal modernization (Lis, 2019;Lis, 2013) of the ventilation and air conditioning systems is an effective way of reducing energy costs, at condition of inflow and exhaust recuperators application with the utilization of heat of the exhaust air in small industrial premises.…”

The article is devoted to solving the urgent task of increasing the efficiency of air distribution by swirled-compact air jets to ensure the normative parameters of indoor air. The dynamic parameters of the swirled-compact air jet during its leakage in the alternating mode and the formation of a dynamic indoor climate in the room are determined. For improvement of comfortable conditions in the room and design of energy saving circuits of air distribution it is suggested to use swirled-compact air jets, which flow from the inflow and exhaust heat recuperators with heat recovery of the exhaust air. An energy audit of the ventilation system reconstruction with a recuperator using was carried out. The method of taking into account the fact of application of several measures, which cannot be carried out simultaneously, and discount rate dynamics is proposed.
