The present research aims to advance green energy consumption by integration of energy conversion schemes into buildings, as an inherent part of architectural construction. Realization of such tasks implies variation and adjustment of external shapes of buildings. Particular solutions depend on the chosen types of renewable energy sources, geographic location, and environmental conditions. The novelty of suggested solutions based on the principle of preliminary crowding of solar radiation, but against known analogs concentration of light by mirrors here used not for achieving of high amplitudes, but for diurnal equalization of an energy conversion process. Autodesk software products have been used for adjustment of conceptual schemes, including the models of buildings shaped as right circular, or elliptic, cylindrical reflectors. The basic evaluation carried out for the North Temperate Zone. Obtained results confirm that integration of local energy converters and appropriate modification of external shapes of buildings is more flexible and efficient than the application of centralized solar plants, because of their inexpensiveness and harmonization of beauty and energy efficiency. Application of static self-regulation of illuminance provides a high level of reliability and simplicity in exploitation. Suggested principle provides stepwise promotion of sustainability because it implies not only a passive economy of energy dissipation but also the equipment of architectural objects with inherent modules for active generation of renewable energy. Further development of such an energy sourcing schemes related also with the advancement of general safety (lowering of hazardous voltage) by the transition from common Electrical grid to adaptive local systems.
