The main goal of the article is the efficiency justification of energy-efficient house (EEH) from the different points of view: economic, ecological and social. In this case, the EEH under the green economy context was considered by the authors. In addition, according to the Ukrainian ongoing condition, the key preconditions of EEH implementation among the Ukrainian households were allocated. Besides, the main approaches to define EEH are analyzed and systematized by the authors. On this basis, the main bullet points and features of EEH were indicated. The authors determined the EEH opportunities for spreading among the Ukrainian households. It should be noted, that the lack of awareness among the civil society provokes the slow temp of the EEH enlarging in Ukraine. At the same time, the European experience showed that the huge part of their households can be characterized as energy-effective. With the purpose of understand the efficiency of EEH, the authors had estimated the economic benefits of installed solar collector in the household as one of the parts of EEH. According to the results, the authors allocate the restraining factors of the EEH spreading in Ukraine. Thus, the great payback period is one of them. In addition, the high level of the currency rate has negative impact on the payback period. From the other side the continuously increasing of the utility bills have been indicated as a negative stimulate factor. In order to increase the awareness of the EEH benefits under the Ukrainian civil society, the main economic, ecological and social benefits of EEH were systematized by the authors.

This paper deals with macroeconomic stability impact on improving the countries’ energy-efficiency. For that purpose, the authors conducted the bibliometric analysis using the VOSviewer and Scopus tools. The investigation involved 1335 studies focused on economic stability and 1811 studies – on environmental issues. Thus, the obtained results demonstrated the strong links between investigating environmental factors, particularly, energy efficiency, on business performance, economic and macroeconomic stability. Given that, the authors made forecasting energy-efficiency development. In the current research, primary energy consumption was allocated as a basis for forecast the energy-efficiency. The study involves data between 1991 to 2018 from European countries (EU27) taken from the Eurostat database. The methodology of this study was based on ARIMA model. From the results, the authors concluded that the EU energy targets would be gained by 2020. However, the obtained results allow prognosticating increasing the final energy consumption from 2020 to 2029. Based on analysing the EU experience and the forecast findings, the authors allocated the main recommendations to improve the energy-efficiency in Ukraine. The authors noted that current results are considered to be the base for future investigations aimed at the analysis of the macroeconomic stability impact on increasing energy-efficiency level.
