Formulation of the problem. To date, in Ukraine, once again demanded the erection of low-rise buildings. Despite the fact that more than 70% of "new buildings" in large cities of Ukraine are high-rise (21-26 floors), public show that already today 60% of people would prefer an individual apartment house. In addition, according to the State Statistics in 2017 in Ukraine, dacha and garden houses with a total area of 73.4 thousand m2 were put into operation, which, in comparison with the corresponding period of the previous year, increased by 16.8% [2, 7]. Since 2017, an updated normative document [3] has been in force, based on European experience, a new model for the calculation of energy losses of buildings is proposed. Therefore, one of the areas of modern building design is the development of efficient energy-saving technologies and constructive solutions for external fencing that meet regulatory requirements. The article is devoted to a new technology for erecting low-rise buildings with energy-efficient enclosing structures. The novelty of the constructive and technological solution is confirmed by the utility model patent [8]. Goal. On the basis of experimental studies, determine the impact of organizational and technological factors on performance indicators (cost, labor and duration) of a new technology for building energy-saving buildings. Conclusion. The methodology and results obtained in this paper make it possible to determine the regularities in the change in the efficiency indices of construction-cost, labor and duration, under the influence of organizational and technological factors. The methodology is based on the construction of three types of models: economic (estimated calculations in the AVK-5 program), graphic (production schedules in the Microsoft Project 2010 program) and analytical (using the COMPEX program). Based on the constructed patterns of change in the performance of construction, zones of effective building solutions are determined.
