“…Application of the suggested principle even theoretically cannot cause discomfort for people in neighboring location. For illustration of benefits associated with the application of suggested principle, it can be compared with so-called passive water heaters (Morsink-Georgali et al 2017). In multi-storey urban-type buildings, usually they are mounted on the roofs and mainly are available only for the residents of upper-floors.…”

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.

“…However, there is much less information about optimization of the environmental use of solar installations, including solar tube collectors. Previous studies on solar tube collectors focused primarily on flat collectors [1][2][3]5,[50][51][52][53][54][55][56][57][58][59][60][61][62][63]. In addition to determining the environmental impact of flat collectors, there are also indications regarding their optimization at the production stage [1][2][3].…”

This paper presents an environmental impact assessment of the entire cycle of existence of the tube-vacuum solar collector prototype. The innovativeness of the solution involved using a phase change material as a heat-storing material, which was placed inside the collector’s tubes-vacuum. The PCM used in this study was paraffin. The system boundaries contained three phases: production, operation (use phase), and disposal. An ecological life cycle assessment was carried out using the SimaPro software. To compare the environmental impact of heat storage, the amount of heat generated for 15 years, starting from the beginning of a solar installation for preparing domestic hot water for a single-family residential building, was considered the functional unit. Assuming comparable production methods for individual elements of the ETC and waste management scenarios, the reduction in harmful effects on the environment by introducing a PCM that stores heat inside the ETC ranges from 17 to 24%. The performed analyses have also shown that the method itself of manufacturing the materials used for the construction of the solar collector and the choice of the scenario of the disposal of waste during decommissioning the solar collector all play an important role in its environmental assessment. With an increase in the application of the advanced technologies of materials manufacturing and an increase in the amount of waste subjected to recycling, the degree of the solar collector’s environmental impact decreased by 82% compared to its standard manufacture and disposal.
