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.
