“…But in these studies, the problems of geometric modeling of high-rise buildings are considered when using only passive form of solar energy (accumulation of solar heat and light). In [24], analytical dependences of calculating the values of total solar radiation for the use of heliosystems on horizontal and vertical planes are presented, without the possibility of effective modeling of the solar radiation input on the surface of buildings with a curvilinear geometric shape. Thus, the problems of multifactorial optimization of the integration of solar systems on the curved surfaces of high-rise buildings are not presented by methods for analysis.…”

The aim of research is to simulate the zones of solar radiation on the curved surfaces of the shells of high-rise buildings for the effective use of renewable solar energy. An urgent task is the development of tools that can substantiate the decision-making by designers about the location of solar thermal devices in the energy-efficient design of curvilinear high-rise buildings. The main attention is paid to high-rise buildings, is actively growing in modern megalopolises and requires a significant energy resource. To optimize the integration of solar thermal devices in high-rise buildings, it is important to take into account a set of design parameters, including parameters of surface shape and location in space. A feature of curved surfaces, considered in the study, is their aerodynamic properties, which provide them with the advantage of choosing among modern high-rise buildings. At the same time, the complexity of setting the parameters of a curved surface to determine the zones of solar radiation for the effective use of regenerative solar energy lies in providing reliable and convenient tools for optimizing decision-making. The study proposes an application of the method based on a discrete geometric model of solar radiation input on the surface of the shells of high-rise buildings, described by compartments of curved geometric surfaces. As a result of modeling, let’s obtain a family of lines of the same level of solar radiation on a certain curved surface for the given parameters of time and geographic location. As an example of simulation modeling, the performed calculations of the instantaneous model of the distribution of solar radiation on the compartments of the curved surfaces of an ellipsoid of revolution, hemisphere, hyperbolic paraboloid. On the basis of the proposed model for the distribution of solar radiation over curvilinear surfaces of buildings, the influence of factors arising in the design process is investigated: changes in the geometric parameters of the surface shape, orientation to the cardinal points, the formation of zones of its own shadow on surfaces. Calculations were performed and instantaneous solar radiation zones were constructed on the surfaces of a hemisphere, a hyperbolic paraboloid with various geometric parameters, taking into account different orientations relative to the cardinal points, and determining the zones of its own shadow. At this stage of the study, the result is an algorithm for constructing zones of different levels of solar radiation on curved surfaces of high-rise buildings. The advantage of the algorithm is the ability to analyze the results of changes in the design parameters of the surface of a high-rise building when placing solar systems on them. The proposed approach will provide a basis for automating the modeling process, will help expand the scope of solar systems in high-rise construction and increase the efficiency of their work

Non-traditional renewable energy resources (solar radiation, wind energy, etc.), alternative thermal and electric generators have incontestable positive qualities in comparison with fossil fuel (natural gas, coal, fuel oil), classical systems: relative environmental friendliness, vast total reserves, low operational costs, reliability, ease of management. The scale of their implementation in the Central Black Earth Region can be limited by high initial capital investments, the value of the energy resource, and low awareness of the population. The article presents the results of modeling solar plants functioning during their integration into traditional energy systems of apartment residential buildings. In the article we demonstrate technical and economic indicators of projected and modernized engineering heating services in the city of Voronezh. The technically viable period of use is spring-summer-autumn. Economic indicators put solar systems into the experimental category.
