Abstract
This paper gives examples of the implementation of energy-saving measures in public premises. The introduction of energy-saving measures at enterprises significantly reduces the fixed component of industrial expenditures. As a rule, educational institutions, for example, public premises, are financed from the state budget, and saving money on utilities will enable redirecting finances to the development of the university’s educational and scientific base. Thus, the main purpose of implementing such measures is to reduce the cost of maintaining buildings. The measures are divided into three stages. At the first preparatory stage, the problem elements of a building and communications, which require the introduction of energy-saving measures using a special Fluke Ti25 device, are identified. Problem elements of the building structure were determined by complete scanning of the ceiling, walls, and floor with the help of a thermal imager. A large (more than 10 %) difference between indoor air temperature and the temperature of the building element indicates a problem element. The research method is thermographic. The study contains an example of scanning the wall of the premises. The temperature difference between the left and the right sides of the wall is 2.6 °C (the difference with the room temperature is 21 %). This indicates significant heat losses through the wall. At the second stage of information processing, measures to reduce energy consumption were determined. At the third stage of the introduction of energy-saving measures, the measures that directly affect the energy consumption of a building and effective functioning of communications were implemented. The practical relevance of the study is to obtain results and practical recommendations that can be applied in practice to improve the energy efficiency of premises and buildings.
Highlights
Unstable pricing policy in the provision of energy resources leads to the actualization of the issue of energy-effective use of thermal energy
The aim of the research is to determine the places of significant heat losses in public premises by the thermographic method and to develop an algorithm for the examination of the entire building, which will make it possible to increase the efficiency of implementation of energy-saving measures
Analysis of thermography image IR004422.IS2 of the device Fluke Ti25 indicates a decrease in temperature on the floor stairs to 16.3 °C, which is 18.5 % lower than the temperature in the premises, which is equal to 20 °C
Summary
Unstable pricing policy in the provision of energy resources leads to the actualization of the issue of energy-effective use of thermal energy. The use of the method for minimizing the energy consumption process becomes quite relevant [5, 6] This is done by calculating the justified volumes of energy consumption and approaching them by optimizing heat transfer between processes, methods of energy supply and improving the characteristics of technological processes [7, 8]. This method is called pinch analysis or integration of processes [9]. The issue of the development and improvement of methodological and technical foundations for energy-saving measures is relevant [1]
