Problem statement. The design of ecological buildings requires taking into account all the features of the climate, geographical location and terrain. As a result of such researches there are whole directions of development of architectural design: kinetic, dynamic, glass, water, etc. Experimental technologies combining the movement of the house and the maximum absorption of solar energy make the solar house more energy efficient and energy independent, and today this area of research is very relevant. The aim of work is to determine a rational structural scheme of a solar house and to determine the possibility of using VIM technologies for modeling such houses. Conclusions. The development of building modeling technologies allows the development of new areas of research and design of buildings and structures. BIM technologies provide a powerful source of choice of energy-efficient and rational architectural and structural solutions. There is a stained-glass main facade to increase the energy efficiency of the house and allow the maximum amount of solar radiation inside the premises in winter or it is possible to place transparent solar cells. Also, due to the found optimal value of the roof overhang to minimize the ingress of solar energy into the house, thereby reducing energy consumption for air conditioning.
