Automotive transport plays a crucial role in the functioning and development of any country's economy. In Ukraine, it accounts for over half of passenger transportation and three-quarters of freight transportation. A promising development direction is using electric and hybrid vehicles in transportation logistics. It also fosters advancements in battery production technologies, components of hybrid power units, recycling, and the country's transportation infrastructure.

The process of intensive industrialisation in the West, and later in many other countries around the world, has led to a number of economic and environmental challenges. According to rough estimates, at the current rate of growth of the world's population, basic energy resources will become increasingly scarce. The main amount of these energy resources is used for heat and power supply to buildings and structures of various purposes, depending on their use. Residential buildings are among the first in the list of such structures.

The paper presents the history of the formation of historical residential buildings in Ukraine and analyzes the reasons for the dense development of historical neighborhoods.

This article presents a comprehensive analysis of hybrid unmanned aerial vehicles (UAVs) equipped with ducted and asymmetric propellers. The results of experimental studies confirm the advantages of using these types of propellers regarding aerodynamic efficiency, energy efficiency, noise reduction, and improved maneuverability. The possibility of combining asymmetric propellers with ducted designs, as well as their impact on thrust, flight stability, and other flight characteristics of drones, is examined in detail.

The article is devoted to the study of circular economy, its concept; the main circular business- models, their essence and advantages in the practical application based on the analysis of researches of their introduction and use in the world and domestic companies are analyzed; features of the development of circular economy in Ukraine in disclosure of researches of sources of financing of innovative activity and a share of innovative enterprises in general scale are revealed; the expediency of introduction of energy-efficient and energy-saving technologies at the enterprises within the li

The article presents an analytical review of promising trends in apartment housing for the next 15 years. In particular, the following trends have been identified: increasing the role of energy efficiency, reducing housing stories, increasing dwelling diversity, increasing the role of environmental and ethical factors in diversifying housing management, modernization, cooperative building retrieval, appearance housing policy. 

The article identifies the main conditions and problems of introducing energy-efficient technologies for business in Ukraine and considers the design experience of building green commercial buildings that have been erected in recent years (innovative parks UNIT.City in Kiev and LvivTech.City in Lviv, on the Sobachie mouth peninsula, Astarta Business Center in Kiev, etc.) It has been established that the main problem of introducing energy-efficient technologies in public commercial projects is the insufficient participation of the state in financing and stimulating business.

The importance of improving energy efficiency in production, transmission, distribution and trade, as well as the use of energy for the implementation of sustainable development policies in the country, has been established. The concept of “energy efficiency” based on the analysis of literary sources is specified. The factors of influence on the implementation of energy efficiency and its barriers were identified.
