Engineering aspects of the functioning of the energy management system of housing and public facilities

The authors continued previous studies, which were aimed at creating scientific and technical solutions for the development and implementation of energy management systems in educational sector, methods of energy assessment and certification of buildings, typical structures of control, monitoring and management systems, algorithmic and software for information systems aimed at energy consumption processes management, performing energy modelling of representative premises or buildings of simple geometry, taking into account the influence of climatic parameters, operating modes of the heating and ventilation systems.
A complex has been developed that combines dynamic models of the building energy balances and the thermal comfort of a person, which makes it possible to determine the dynamics of changes in their characteristics and the interaction between them. Multifactorial nonlinear inertial regression models have been created to analyse and predict the heating energy demand and air temperature in a building.
Mathematical models of multi-storey buildings of complex architectural design have been created, which allows taking into account more complex forms of air exchange and energy interaction between zones with different orientations, the level of thermal protection and the characteristics of building technical systems; a toolkit for the functioning of the energy management system for end users of the housing and public sector has been developed. To clarify energy modelling parameters, compare and verify the results, energy surveys of pilot buildings were carried out with the definition of dispersed local data on operating conditions, namely, comfort, energy consumption, etc.
The provisions and methods for organizing energy management systems, methods and models for organizing heat supply using local heat energy markets have been improved.
In accordance with the requirements of the recently adopted laws of Ukraine, the task of improving the quality of building energy costs management and the relationship between the readings of the commercial metering unit and the energy costs for individual consumers of the building is of high importance today. Recommendations for creating the primary database and further management of energy consumption in multi-apartment buildings have been developed, as well as the distribution of costs between individual consumers, depending on technical, operational characteristics and social factors; energy monitoring technology and models for predicting the buildings energy performance for operational control and response to changes in operating conditions.
