The article presents and substantiates an extremely important problem of today, which consists in the lack of electrical energy to meet the needs of consumers, as well as the impossibility of clear and detailed accounting of the use of energy resources by individual buildings for the required period - a month, a week, a day or an hour. The shortcomings of existing approaches to accounting for consumption are described, which consist in the monthly collection of information without reference to both the external temperature and the internal parameters of the microclimate. The relevance of the publication is formulated, which is related to the need to develop an automated information and measurement system for monitoring and managing energy supply, which will allow to implement the definition, collection and storage, as well as the possibility of analyzing hourly and daily indicators of energy consumption by various objects or equipment by types of resources, recording parameters of the internal microclimate in the premises, as well as to carry out operational management of the functioning of the energy supply system. The main components were selected and a structural diagram of such an information and measurement system was proposed, which was eventually implemented in a part of the university building and which covers a total of 10 classrooms. The implemented system allows you to get information about the consumption of heat, electricity, and water in specific rooms, as well as get online information about the parameters of the microclimate in them, namely, temperature, humidity, and carbon dioxide content in the air. In addition, the system implements a weather station that allows you to record the parameters of the external environment: temperature, atmospheric pressure, humidity and radiation background. All information from the respective sensors is transmitted via Wi-Fi to the cloud storage, from which both the data history and the real online values from the university premises connected to the system can be obtained. The developed information and measurement system have sufficient accuracy for each of the measurement channels and in the future will allow to implement it as a whole in the university and obtain the necessary information on energy consumption in order to further implement the most optimal energy-efficient measures.
