The article considers the use of renewable energy sources in construction in general and in high-rise unique buildings. Such an approach will allow to design and build buildings in which integrated renewable energy sources can be harmoniously entered into all aspects of construction. This is especially true for high-rise buildings. With the implementation of energy-efficient technologies, the main drawback - high energy consumption - will be cut off. The article analyzes non-traditional sources of energy, such as wind, solar, land, water and biomass. The relevance of their application in construction and influence on all aspects of the project is proved: town-planning, functional, space-planning, architectural and artistic, constructive and engineering.

We obtained the solution of the optimization problem for the step-parallel beam with constant width of the cross-section. The problem was solved by minimizing the strain energy while the volume of beam is constant. The solution was made for the case of simple support at the ends and evenly distributed along the length load. We introduced the parameter α, which is the ratio of height of the average part to a height of side parts. The optimal value of α was found. At this value the stiffness of the beam is maximum at constant volume. The obtained beam of maximum stiffness is not equal strength.

We solved the problem of optimizing the gable beam by minimizing the strain energy at constant volume. The problem reduced to an integral equation for determining the optimum angle of the beam. This equation was solved numerically by the method of bisection. Integral was calculated using the method of trapezoids. Solution was made in software package Matlab. The optimum angle depends on the width of the cross section b, and the volume of the beam. It was found that with increasing of width of the cross section the optimum tilt angle decreases. Also the volume increases by increasing the width of the beam.
