енергетична ефективність

This study presents an in-depth analytical investigation into the operational efficiency of boiler plants in industrial enterprises, incorporating the principles of building thermophysics as a fundamental component influencing energy performance. The research focuses on the interaction between the thermophysical properties of building enclosures, architectural design parameters, and the thermal regimes of boiler equipment.

The article investigates the European experience of state policy regarding energy efficiency in the residential construction sector and analyzes the primary EU regulations that govern this area. Particular attention is given to the evolution of energy efficiency policy from the late 20th century to the present, with an emphasis on the main challenges and outcomes of implementing the respective directives. The article explores financial and macroeconomic approaches to assessing energy efficiency, as well as the mechanisms of administrative and economic regulation.

The paper presents the results of analysing the activities of a machine-building enterprise, taking into account the influence of factors of the political and socio-economic crisis. Based on the results of the PEST- and SWOT-analysis, the most promising directions of sustainable development of an engineering enterprise are identified, namely, implementation of energy-efficient solutions, use of circular economy principles, application of environmentally friendly technologies, digitalisation, and personnel training.

The growing demand for electricity and the need for environmentally friendly energy sources are driving the active development of renewable technologies, with solar energy playing a leading role. Photovoltaic (PV) systems are capable of converting solar radiation into electrical energy; however, their efficiency depends on the ability to adapt to changing external conditions, such as solar irradiance and ambient temperature.

In today’s environment, domestic enterprises are increasingly aware of the importance of transitioning to green energy. In this direction, organisations are considering emission standards, using energy-efficient technologies, considering environmental aspects of production, etc. Businesses that reduce their carbon footprint are generally more likely to attract investment. They are also more socially oriented and balanced in terms of sustainable development.

Сформульовано вимоги, обґрунтовано принципи побудови, розроблено узагальнену архітектуру інформаційно-аналітичної системи для оцінювання, прогнозування та управ- ління енергоефективністю економіки регіону, визначено основні функції компонентів.

The requirements have been formulated, principles of construction have been grounded, thegeneralized information-analytical system architecture for evaluation, forecasting and energy efficiency management of regional economy has been developed, the main functions of components have been defined.

Predicting a building’s energy consumption plays an important role as it can help assess its energy efficiency, identify and diagnose energy system faults, and reduce costs and improve climate impact. An analysis of current research in the field of ensuring the energy efficiency of buildings, in particular, their energy assessment, considering the types of models under consideration, was carried out.

Considering general trend of energy consumption, according to which the amount of consumed energy increases, its cost and scarcity continuously increase. The 10–12 % of all energy is spent on drying processes in the world. At the current stage of the development of dehydration processes in Ukraine and the world, an urgent problem has arisen in the creation and development of highly efficient thermal technologies that would ensure minimal energy consumption for the process and high quality of the material.

Problem setting. One of the most pressing issues of the development of the fuel and energy complex of Ukraine, the discussion about which has been going on for many years, is the question of the size, forms and directions of state intervention in the activities of individual industries and sub-sectors of the complex, as well as the assessment of the consequences of this intervention for the economy and society as a whole.
